Thinking and being green in the garden

Buy less plastic, stay away from chemical fertilizers and compost

Do you want to be a better steward of the environment? If so, the first step is to be a gardener: Grow some of your own vegetables and plant some native trees, shrubs and flowers while using no chemicals. But there is even more to think about than what kind of tomatoes to plant, and how many.

First, what should you do with all those black plastic pots that come with the plants? Most recycling facilities do not accept black plastic pots, but some pots are numbered #2 or #5 and can be recycled. A few have no numbers. Plastic pots are made from oil in factories around the world. I imagine that these factories spew and spill a certain amount of chemicals, and create waste and byproducts that are bad for the environment.

My mantra for plastic is this: Refuse, Re-use, Recycle. So how do you refuse to buy plants in plastic pots? Start your own plants. If you save plastic pots and rinse them out, you can reuse them. Some for years. You can also buy peat pots and coir (palm fiber) pots. Some companies, like Gardener’s Supply, sell sturdy flats to use instead of those flimsy six-packs, strong enough to be used many times.

Trees and shrubs are most often sold in big black plastic pots. But they are also sold “balled and burlapped.” Those are usually bigger trees that are dug up and wrapped in burlap after years growing in the ground. Some local nurseries still dig their own plants, and I recommend supporting them. When you plant, be sure to take off any burlap and wires that may be holding the root ball together. And beware of any “fake” burlap made of plastic. Don’t buy it.

For years we have been offering sturdy plastic pots to our local, family-owned garden centers. Most just want them cleaned before you drop them off. I find it easiest to do that right after planting, before the soil bakes on. Reusing pots saves the garden centers money, assuming they have the time to sort and store them. Tell those that do how happy you are with them.

Recycling is really not the answer: Many loads of plastic at the recycling center are contaminated and end up in the landfill or incinerator. Too much dirt, food or items of the wrong number can condemn a whole Dumpster of plastic.

I was pleased to learn that most Home Depot stores now accept all kinds of plastic pots. I went to the one near me in West Lebanon, New Hampshire, and there was a rack outside with the plants just for returned pots. The pots don’t even need to have come from them.

We recently took a big step forward toward being “green.” We bought an electric lawn mower. I’ve read that the EPA estimates that using a lawn mower is 11 times more polluting than driving a new car. One hour of mowing, apparently, is equal to driving 93 miles. Of course, these statistics are not perfect, as they do not indicate what kind of mower or car is being compared. Older, bigger mowers are worse.

We bought a 21-inch, self-propelled battery-powered lawn mower on sale for $500 at our local True Value Hardware store. It has a quick-charge battery charger that takes an hour or less to recharge the 54-volt battery, which is good for an hour of mowing. The mower has plenty of power and is so much quieter than our old gas mower. Our lawn takes more than an hour to mow, but so what? I have plenty of other garden chores to do while the battery recharges. The technology in batteries in electric mowers really has improved just in the last few years.

Being green also means using no chemicals in the garden. That’s an easy one. I don’t use herbicides, insecticides or chemical fertilizers. I don’t want something to kill dandelions or moss, neither of which I consider a problem.

There are perfectly wonderful organic fertilizers that offer so much more than the chemical ones. Instead of just offering three plant nutrients (nitrogen, phosphorus, potassium), they offer calcium, magnesium and many more nutrients plants use. They do this because they are manufactured using natural ingredients like seaweed, cottonseed meal, ground oyster shells and ground peanut hulls.

Organic fertilizers are also slow-release fertilizers. Pro-Gro, made in Vermont, has about 25 percent soluble nitrogen that is ready right away. The rest is released slowly as microorganisms break it down and make it usable by plants. And it will not damage root hairs the way some of the chemical fertilizers can if too much is applied.

Compost is one of the best things you can add to your soil. It helps sandy soils hold moisture and loosens up heavy clay-based soils. You can buy it by the bag or, better yet, by the truck load. Even though my soil is terrific, I add compost every year. It is not a fertilizer, but it feeds the microorganisms that work with our plants. And if you get a good grade of compost, it will improve the texture of your soil, no matter what it is.

Lastly, speak up. If your suppliers are trying to reduce use of plastic, or are taking it back to reuse it, tell them that is why you are buying from them. If they’re not? Ask them to! Every voice counts. We gardeners should be on the cutting edge of reducing plastic and chemical use.

For the water-logged garden

Plants that thrive in wet or moist places

I like to say that plants can be as fussy as a 2-year-old facing a plate of overcooked broccoli. Plants know what they want, and will not behave the way you want them to unless you accommodate their wishes. Today let’s look at a few that love wet feet.

First, please understand that plants need oxygen but do not get it from their leaves. No; they get oxygen from their roots. Some plants have evolved ways to get their oxygen despite sitting in water-logged soil while others quickly drown or develop root rot. If you have heavy clay soil that holds water, be sure to pick plants that can tolerate wetness.

I have a small stream running through my property, so much of my land stays quite moist, even in dry summers. In spring I often have standing water between raised beds in the vegetable garden. Yet I have plenty of wonderful flowers that thrive here. Here are a dozen I like, arranged roughly according to bloom time, from early spring to late fall.

1. The drumstick primrose (Primula denticulata) blooms in early spring in hues of blue to red or white. Then comes P. kisoana, which spreads by root in either wet or dry places. Last, starting now, there is the candelabra primrose (P. japonica) which sets out a series of blossoms on an increasingly tall stem over a month of bloom time. All love growing under old apple trees in dappled shade.

2. Forget-me-nots (Myosotis sylvatica). I have these blooming now by the hundred everywhere I look, sun or shade. These lovely low-growing blue (or sometimes pink or white) flowers self-sow bountifully. They prefer rich moist soil and will do well in sun or shade. Because they come back from seeds so easily we let them bloom, then often pull them out like weeds to plant something else.

3. ‘Thalia’ daffodil. Most bulbs require good drainage, but ‘Thalia’ does fine in soggy soil. She is nearly white, and each bulb can produce three flowers at once. She blooms with the forget-me-nots. Order now for fall planting.

4. Globeflower (Trollius spp.). An early summer bloomer, it does best in part sun and moist soil, but will also grow in ordinary garden soil and in full shade. The blossoms are an inch or so across and bright yellow. Blooms in late May to June, but may sometimes re-bloom in the fall.

5. Japanese iris (Iris ensata). These beauties will bloom in standing water or in damp soil. They are like the Siberian iris, but their falls (petals) lay back almost flat. Blues and purples. Early summer.

6. Cardinal flower (Lobelia cardinalis). These flowers are native plants that bloom on 3-foot stalks in fire engine red! I’ve seen them growing on the banks of the Connecticut River, but they do well in moist soil and full sun in my garden. Will tolerate some dryness, but prefer wet. I avoid modern hybrids that are other colors but not as hardy.

7. Swamp milkweed (Asclepias incarnata). Related to ordinary milkweed, this likes moist soil and full sun. Unlike the wild one, this does not send runners out and spread by root. Mine get 3 to 5 feet tall and come in pink or white. Readily available at garden centers.

8. Astilbe (Astilbe spp.) These flowers come in red, pink and white and various heights. They can survive in drier soil in shade, but really love moist, rich soil and full sun. Good cut flower with an almost woody stem.

9. Goldenrod (Solidago spp.). There are many species, some of which spread by root while others do not. It is the very best perennial for supporting pollinators. Mid-summer to fall. ‘Fireworks’ is my favorite.

10. Joe Pye weed (Eutrochium purpureum). This is a native plant that thrives on stream beds and swampy areas that has been domesticated. A cultivar known as ‘Gateway’ is the best but gets to be over 6 feet tall. ‘Baby Joe’ is supposed to be a smaller version, but I haven’t tried it yet. Pollinators love this plant, which blooms in fall with pinky-purple blossoms.

11. Turtlehead (Chelone lyonii). Gorgeous tall stems loaded with pink flowers shaped like helmets – or turtle heads. Will do sun or shade, loves moisture but will grow in ordinary gardens, too. Bumblebees force themselves inside, and seem to growl in there at times. Great cut flower. Fall.

12. ‘Henry Eiler’ rudbeckia. One of the latest flowers I grow. Petals are distinctive: They have space between each one, like missing teeth. Tall, often 6 feet or more. Needs to be staked early, or perhaps cut back in early June to reduce height. Blooms past frost. Full sun, rich moist soil.

If you have a clay-based soil that is sticky when you rub it, wet, between your fingers, you would do well to add compost to the soil before planting any of these lovely flowers. Yes, they like the moisture clay holds, but compost — a shovel or more mixed into the planting hole — will improve their performance.

I’m pleased to report that our new young dog, Rowan, is learning to stay out of garden beds. He’s an 18-month-old golden/Irish setter mix with lots of energy. But so far, he hasn’t dug up any plants.

Getting rid of invasives

How to rebalance your plant life

Well-intentioned people of the past century imported many handsome plants. Unfortunately, some of them, absent the predators of their homeland, became pests here in America. These “invasives” generally spread quickly by seed and root, and can take over our gardens and adjoining wild places. Many will grow in sun or shade in wet or dry soil — in other words, anywhere!

This is a good time to work on removing as many invasives as you can. You can obtain the entire list online as each state keeps a list of plants that are considered invasive and are prohibited from sale, propagation or transportation. But let’s look at a few that are common and important to remove, no matter where you live.

For me, those include bush honeysuckle (Lonicera spp.), barberry (Berberis thunbergii) and common buckthorn (Rhamnus cathartica). I recently organized a work day on a hiking trail in Cornish that focused on honeysuckle and barberry. We tried to pull these shrubs by hand, but also used a device called a weed wrench for bigger specimens.

Although “weed wrench” is used generically, it was in fact a trade name, but the company has gone out of business. Similar tools can be found under the names “Pullerbear,” “Uprooter” and perhaps others. I have used Weed Wrenches, but not other brands. These are steel tools with sturdy handles and a gripping mouthpiece that bites onto the stem of a shrub up to 2 or 3 inches in diameter, depending on the model. You pull back, and with great leverage you pull out the culprit, roots and all. Some brands come in different sizes.

Many invasive plants are hard to eradicate because if you leave a part of the root in the ground when pulling it out, it will re-sprout. And simply cutting down an invasive tree or shrub usually will often not work: The roots will send up new shoots, and may respond by sending up many, many new shoots.

But don’t be discouraged if you can’t get all the roots out. You are severely setting back the plant you pulled and it will be several years before the plant can produce seeds for birds to distribute elsewhere.

Buckthorn is one of those that responds to cutting by sending up many new plants. Instead of one buckthorn or a clump of buckthorn, you get dozens of buckthorn. But you can kill buckthorn by girdling the trunk. Take a small pruning saw and cut through the bark all the way around the trunk. Don’t cut into the hardwood, just cut the bark. Then go 12 inches higher up, and do it again.

Girdling a buckthorn is a slow death: you are interrupting the flow of sugars from the leaves to the roots, which slowly starve to death. I have done this in winter, and the tree leafed out and seemed normal that spring and the next spring. The third spring it never leafed out — it was dead, and did not send up any new sprouts around the tree.

That said, it is not always easy to girdle buckthorn. They often grow with several trunks that merge near the base and grow tightly together. So a folding saw with a pointed tip is the best way to get into the cluster of stems. Or try to cut the clump twice down low, near the base.

During the recent work day in Cornish, I spoke with someone who explained a theory of invasive plant control that made a lot of sense to me. It was a theory proposed by Dr. Steve Dewey of Utah State University, and was based on the way firefighters approach wildfires. When a fire is raging, sometimes all you can do is try to contain it, and look for places where the wind has sent sparks that are just starting a new fire.

Likewise, when there is a bad infestation of an invasive plant like honeysuckle or barberry on a property, look around for spots where a single small plant is growing. It will be easier to pull than a big one. And within a few years, a small plant will be a big plant producing seeds for birds, wind or water to move to a new location — and to produce a big patch. So put out the glowing ember first, then work on the big fire — or infestation — next.

An easy invasive plant to pull is garlic mustard. This is a biennial weedy plant and might not be thought to be so bad. But its roots produce a toxin that kills beneficial soil fungi that will, in time, reduce tree viability. It can grow in deep shade in our forests. The toxin it produces will eliminate the mycorrhizal fungi that live in symbiotic relationship with our trees, gradually weakening the trees — and killing them. Not only that, garlic mustard inhibits the germination of seeds of many species of native plants, including many spring wildflowers.

As a biennial weed, garlic mustard has two forms. In the first year it produces a low rosette of rounded leaves. The second year it sends up 18- to 36-inch flower spikes with pointy, heart-shaped leaves with jagged edges. The small white flowers have four petals and bloom in clusters about an inch or more in diameter. One plant can produce about 4,000 seeds. And although about 70 percent of the seeds will germinate the next year, some will remain viable in the soil for up to 10 years.

So organize a work party in your town — it’s more fun than taking on invasives on your own. Try to remove any one of the invasives that threaten our woodlands and wetlands. Your grandkids will thank you one day.

Planting the vegetable garden

Every gardener has an opinion about when to start planting the vegetable garden. Frost-hardy plants like spinach, onions and peas should already be in the ground for most everyone, but tomatoes and peppers? I believe that waiting until June is right for my garden, even if we get no more frost.

Why do I plant later than many others? Tomatoes and peppers like warm soil. In fact, they’d rather be growing in Mexico than Cornish Flat. Yes, you can plant them early, but they won’t grow much. They’ll sit there and sulk. If you can get your hands on a little soil thermometer, check your soil down 3 or 4 inches. If it is 60 degrees or more, fine. Have at it.

Another way to decide when to plant is to ask an “old timer.” Ask someone in your neighborhood when it is safe to plant various crops. If she has been gardening in your neighborhood for the last 25 years or more, her advice is probably excellent.

If you started seeds indoors, your tomatoes or broccoli may be tall and lanky. So tall that they will fall over when planted. The solution? Plant much of the stem in the ground, either in a deep hole for the root ball, or sideways in a shallow trench. Remove any low leaves to make it look like a little palm tree. Then make a hole for the root ball with a 6-inch trench next to it. Lay the tomato seedling in the ground, and gently turn up the top while covering the stem with soil. All the buried stem will produce roots. Broccoli or other brassicas I just plant deep if they are too tall.

Potatoes can go in the ground now unless your garden is still soggy. In fact, don’t plant anything in soggy soil. I have a somewhat soggy place for my garden, but I make raised beds, which helps with drainage. I have made two kinds of raised beds: raised mounds (30 to 36 inches wide) or wood-sided raised beds. I use rough-sawn hemlock planks that are a full inch thick and 8 inches wide. Pressure-treated wood is now said to be safe to use in the vegetable garden, but I prefer untreated hemlock, which I find lasts about 10 years.

Potatoes are started from chunks of sprouted potatoes, or from whole, small potatoes. Buy “seed potatoes” at your local feed-n-grain store, hardware store or garden center. Grocery store potatoes are likely treated to avoid sprouting, although organic potatoes are probably fine. Seed potatoes are sold as disease-free, which is important. If you cut large potatoes into chunks, make sure each has a couple of “eyes,” where they will sprout stems. Leave them in a shady, breezy place for a day or two to heal the cuts.

Loosen the soil well and dig a hole with a hand tool. You want the spud to be at least 3 inches deep when planted as the new potatoes need space to grow above the seed potato. Cover with just an inch of soil at first, but then fill the hole with more soil after the leaves and stems are up above the soil level.

Peppers and eggplants I plant as small plants in mid-June. To give them even more warmth at night I sometimes cover them with row cover (a thin agricultural fabric sold at garden centers). And I’ve been known to place dark-colored rocks near some special French hot peppers I grow to store heat during the day and kick it back at night. Peppers and eggplants can be wind-pollinated, but bees help too, so don’t leave row covers on once they start blooming.

Parsnips I plant by seed in mid-June, and they generally take two weeks or more to germinate. Most seeds are good for three years, but you must buy parsnip seeds every year. Like all root crops, parsnips benefit from having loose soil with few rocks (oh, sorry, Vermonters).

Be sure to thin all root crops in early July once they are big enough to grab onto. Give the carrots an inch to start, then a month later thin to 2 inches. You can eat the thinnings. Beets, same thing. And beet greens are delicious.

What about unusual veggies? I like to buy an artichoke plant at my local greenhouse. I have started them from seed, but it is a long process starting in February. Give your artichoke a 2-foot square of space, add lots of compost and a little organic fertilizer, and place it in full sun. Make sure it does not dry out. It will produce one good-sized artichoke at the top of the plant, and smaller ones as side shoots. The foliage is lovely, so you can plant one in your flower garden!

Swiss chard is pretty enough to sneak into your flower beds. Get Bright Lights chard, which has red, yellow and green stems.

Beans come as bush beans or pole beans. Bush beans all ripen over a three-week period and are then done. Pole beans, if you keep on picking them, will keep producing until frost. Kentucky Wonder is the classic pole bean, though Kwintus is my favorite. It’s good eating, even when large.

A word of caution about fertilizers: More is not better. Chemical fertilizers can burn fine roots. And too much organic fertilizer can push growth too fast. Compost is always a good addition to your planting hole.

I never use insecticides in the garden. Their side effects can be awful for you, your kids or pets. Just hand-pick bugs, or spray off little things like aphids with a stream of water.

Bulbs, shrubs and trees

Spring blooms I love

Spring has teased us this year. She comes, she goes; warm sunny days are followed by high winds, cold rain and even pellets of ice. But the spring flowers persist, starting with those dainty white snowdrops that appear reliably in early March for me. Let’s look at a few — bulbs, shrubs and trees. Perennials I will do on another day.

Snowdrops (Galanthus spp.) bloom with white blossoms on short stems in early March, but seem a bit depressed, I think. They always turn their faces down to the ground. I have some “double” snowdrops that really are gorgeous, but I only see their extra petals when I bend down and turn their faces up. Probably not worth a dollar a bulb, which is what they cost. Snowdrops tend to naturalize, becoming more numerous each year and moving out from flower beds and into the lawn.

After the snowdrops come Glory of the Snow (Chionodoxa luciliae). These are cheerful blue, pink or white flowers that look up to look at me. Sometimes I think they wink at me, saying, “Hey dude, look at us. We are spring.” I mainly grow the blue ones. These naturalize well, spreading quickly.

Related to Glory of the Snow, but more intense in color and attitude, are Siberian squill, most commonly referred to by their scientific name, Scilla (Scilla siberica).They are a deep purple, and their faces point down, looking at their sneakers.

Along with those flowers come a bright yellow one, Winter Aconite (Eranthis hyemalis). These are low-growing, upward-facing flowers with five to eight petals (actually sepals, but who cares?). Like the others, they tend to spread and increase in number. Order some now, along with the others mentioned, and plant them in the fall.

You know crocus, but you might not know that there are 80 or more distinct species of crocus. Some are very early, others bigger and later. Go online and look at all the varieties. These are good for early pollinators hungry for pollen and nectar.

Daffodils are mildly poisonous to rodents and deer, so they avoid them. Mine are now in full bloom. There are 13 classes of daffies, each quite distinct. Tulips are flavor treats for deer, and rodents love the bulbs. So maybe you should grow them as potted flowers. Or take your chances. Having several cats will help tulip bulbs survive, and a dog will keep the deer away. My favorite is ‘Maureen,’ a 24- to 28-inch-tall late bloomer, but I love them all!

Most trees do not have showy blossoms. Why not? Most are wind-pollinated, so do not need to attract pollinators with flashy blossoms or great fragrances. You might never have noticed the blossoms of pines or oaks or maples. Actually, you must have seen red maples (Acer rubrum) bloom. They are early, one of the first trees to blossom. The blossoms are small and fuzzy in appearance. But there are so many blooming at once, you will notice them if you hike in the woods in April.

But of the showy trees, the best in my opinion is a hybrid magnolia called ‘Merrill’ or ‘Dr. Merrill’ (Magnolia x loebneri ‘Merrill’) named after the Director of the Arnold Arboretum at Harvard in 1952, but actually bred by Karl Sax. It blooms reliably for me in the last week of April and into May. The blossoms are double, fragrant, and 2 to 3 inches across.

This week my leatherwood bush (Dirca palustris) is in bloom with heart-stopping beauty. It is a small native shrub that blooms in dry shade for me. It has lovely gray bark much like beech trees and yellow blossoms that appear before the leaves. The blossoms are small and elegant, and almost seem to glow. It is not a common shrub for sale in nurseries. Mine has upward-growing branches in a vase-shaped arrangement. I love it and visit every day when in bloom.

Then there is February Daphne. Well, maybe it blooms in New Jersey or Virginia in February, but it blooms in April for me. It has lots of small pink-purplish stemless blossoms up its branches. It is highly fragrant. It is only 3 to 5 feet tall and wide, and rarely needs pruning. It is native to Europe and Asia, not here, and is said to spread by seed distributed by birds. But in 20 years I have never seen a volunteer on my property. Some people react poorly to the sap, and the berries are toxic if eaten by humans. It likes a part sun-part shade spot.

Perhaps a better shrub to choose would be a fothergilla, which is native and early. There are two species, Fothergilla major and F. gardenia, also known as dwarf fothergilla. It has wonderful white bottlebrush flowers in May and best of all, it has fabulous fall foliage color. Red, orange, purple and yellow leaves on one plant! It is not a fast-growing plant, and rarely needs pruning.

Another early bloomer and a great producer of berries for birds is small tree or large shrub called shadbush, serviceberry or by its scientific name, Amelanchier spp. I see them blooming along the roadsides in May, nice small white blossoms that remind me of wild apple blossoms. It has nice gray bark, and they often grow as multi-stemmed plants. I have a few, but the fruit is eaten by birds before I ever get to it.

Love your lawn

It may be time to rethink your outside space

It’s about the right time to do a little work on your lawn if it needs it. According to Paul Sachs, owner of North Country Organics and the author of several books on lawn care, if you want to fill in bare spots, wait until the lawn greens up after winter.

To fix bare spots I use a short-tined garden rake to scuff up the soil. Then I scatter some seed with my hand, just sprinkling it over the spot. Next I sprinkle a thin layer of compost or fine garden soil over the seed. Finally, pat it down with your foot, lightly, or with a metal tamper.

It’s important that the seed not dry out while it is getting ready to grow, so often people shade the seed with a fine layer of hay or straw. Of course hay has seeds, so straw is better, albeit more expensive. You can leave the straw and just let the seed grow through it.

Why do places in your lawn need help? Most lawn grasses do not like to grow in compacted soil. So if you park cars on the lawn, or walk over it every day on your way to the mailbox, it will get compacted. Enter (drum roll) CRABGRASS. Crabgrass will grow in compacted soil, but it is an annual, so it dies each winter — or by late summer if it gets too dry. The solution is simple: Build a stone path to the mailbox and park cars only in designated parking areas.

Let’s rethink the concept of a lawn. Why do we need a large patch of short grass at an even height all around our house? Sure, people with kids and dogs need some place to play ball or Frisbee. And if you like to have friends over and sit around a barbecue grill, a little lawn is nice. But do you really like mowing an acre of lawn once a week, or paying someone else to do it? Maybe it’s time to reduce the size of your lawn and plant some more native trees and shrubs.

Entomologist Doug Tallamy is the author of a terrific book called Nature’s Best Hope: A New Approach to Conservation That Starts in Your Yard. He suggests that we can help birds and pollinators by growing native trees and shrubs — and by adding more to replace some lawn, especially in new subdivisions and in-town lots.

Birds depend on the caterpillars of moths and butterflies to feed their young. He determined that 6,000 to 9,000 caterpillars are needed to feed a clutch of chickadees from hatching to fledging. That’s an amazing number of caterpillars, especially since most of us never even notice them.

Those butterflies and moths will mostly only lay their eggs on trees and shrubs they know: our natives. Even if your barberry or burning bush has been growing in your yard for 50 years, they probably will ignore it and look for an oak, a cherry or a willow — trees they evolved with over tens of thousands of years.

Dr. Tallamy makes a great suggestion about how to think about lawns: Think of lawn as you might throw rugs, not wall-to-wall carpeting. Bump out with trees planted along the edges of your property line, reducing the lawn with native trees. Create nice curves, then add some understory shrubs along the edge of the newly “forested” area.

In addition to the oaks, native cherry and willow trees, other “keystone” trees include birches, poplars (he calls them cottonwoods) and elm. He said just five percent of the genera of plants support 75 percent of the caterpillars. Great perennials include goldenrod (the absolute best), asters, and members of the sunflower family. There are many tame goldenrod species that will not take over your garden, so expand your plant palette to include “Fireworks” goldenrod and other nice varieties.

But back to lawns. My philosophy of lawns is this: If it is green and you can mow it, it’s a lawn. It need not be free of dandelions and Creeping Charlie. Yes, dig out thistles, or anything that hurts your bare feet. But violets? Sure, why not? Anything that blooms will provide nectar or pollen for bees and other pollinators.

Clover actually helps your lawn, despite being called a weed by the companies that promote using the “Weed-n-Feed” chemicals that kill it. Clover fixes nitrogen, taking it from the air and putting it into the soil, reducing a need for lawn fertilizer.

If you want a rich, lush lawn, don’t cut it too short. The longer the grass, the more food produced to grow grass roots.

When you add grass seed to fill in spots, I recommend a mix of seeds, not a pure Kentucky bluegrass, which is the neediest of all grasses. It needs fertilizer, and watering. A “conservation mix” will do better for you. And if you are planting in a shady area, get a mix made for shady places. Those sun/shade mixes are not as good for shady areas as those designed for them.

Soil pH is a measure of soil acidity. If you are serious about your lawn, buy a kit at the local feed-and-grain store or garden center to test the pH. If you have chlorinated water, buy some distilled water to use with the kit. If the soil pH is lower than 6.2, add some lime (ground limestone) to your soil to bring up the number. Lawns don’t do so well in highly acidic soil.

When I see a weed-free lawn, I know it’s been treated with chemicals, and so I won’t walk on it. You, your kids and dogs shouldn’t either.
