Skunk cabbage, witch hazel and more

Here in Cornish Flat, New Hampshire, we recently had our first day that shouted, “Spring is here!” After a night of cool rain, the sun came out and temperatures climbed into the 50s. Now all we need are spring flowers. Me? I solved that problem by potting up bulbs last November and storing them in my cool basement. They rested, grew roots, and now my windowsills are crammed with pots of daffodils and crocus, some blooming, others on the way. They will help to keep my spirits up when we get, as I know we will, day after day of gray drizzle before summer gets here.

Of the outdoor bulbs, the first to bloom are snowdrops. They push up through frozen earth on south-facing hillsides starting in late February. I imagine they can do this by the process of “thermogenesis.” That’s a process whereby a plant can produce a chemical reaction that produces heat. Few can do it, but those that do can get pollinated before anything else.

The poster child for thermogenesis is skunk cabbage. This is a plant I remember well from my boyhood home in Woodbridge, Connecticut. We had a small brook behind the house, and some wet areas along the banks in a woody area. Aside from being the first green plant to sprout, skunk cabbage had the ability to produce a noxious odor that was endlessly fascinating to young boys. I discovered that if I disturbed them they produced a skunky odor that my sister did not like.

Skunk cabbage is related to the common Jack-in-the-pulpit we all know and love. Like Jack, its flower is hidden inside a spathe, or outer leafy jacket. I bought a skunk cabbage plant at Garden in the Woods, a native plant sanctuary in Framingham, Mass., about 25 years ago.

What I did not know was that skunk cabbage is very slow growing and does not spread at all quickly, at least this far north. Only in recent years has it bloomed, though every year the leaves have gotten bigger. Now I know when buying plants to buy at least three in order to make a statement in a reasonable amount of time. Skunk cabbage produces big green leaves and a barely noticeable flower.

Of the native woody plants, spring witch hazel is the earliest that I know. In southern New England it can bloom in January, and here in New Hampshire it can bloom in March. I bought one last summer, and look forward to seeing the blossoms soon. I have several fall witch hazel that bloom in October and November. The blossoms vary from yellow to brownish red and are spidery in form. Small, but plentiful right near the stems.

Forsythia is a nice yellow-blossomed shrub originally from Asia and eastern Europe. Michael Dirr, my woody plant guru, describes it this way: “Rank-growing, deciduous shrub, differentially developing upright and arching canes which give it the appearance that the roots were stuck in an electric socket; always needs grooming, one of the most overrated and overused shrubs; will sucker (slowly) to form large colonies.” That from his “Manual of Woody Landscape Plants,” my favorite text on trees and shrubs.

His remarks notwithstanding, I grew up with it and like it. It is a burst of yellow at a time of the year — April, here — when not much else has bloomed or even leafed out. My gardening Grampy had a large patch of it that had suckered and created a bed 10 feet wide, 50 feet long and 8 feet high or more. My sister Ruth Anne and I would crawl inside the patch of forsythia in the heat of summer for a cool respite — and to hide from grownups.

The trick to managing forsythia is to prune it hard and often. Keep the tips of branches off the ground as they will root in if touching the soil. One can keep it as a nice vase-shaped shrub, and it really does not take much work to do so. Cold-hardy varieties that will bloom in Zone 4 include New Hampshire Gold, Vermont Sun and Meadowlark, among others. Ask at your local independent nursery.

Forsythia forces easily. Cut some stems with flower buds now and place them in a vase, and place it in a sunny window. I shall cut some today and get them blooming in a couple of weeks or less. The key is to recognize the flower buds: they are pointy and often appear on clusters without stalks, right on the stems. Straight young stems that grew last year rarely have flower buds.

In contrast to the flamboyant forsythia is a nice native, leatherwood. This understated plant blooms just as it leafs out in March, April or early May, depending on where you are. It does best in full shade. Although Dirr’s book says it prefers a moist, dark soil, I have it in a dry location and it does just fine. The blossoms are pale to bright yellow, small, but plentiful. The bark is a handsome gray. But it is hard to find in a plant nursery. I bought one several years ago and have looked for others, but have not found another nicely shaped specimen. Look for it. Slow growing, it requires little or no care.

T.S. Eliot wrote in his poem “The Wasteland” that April is the cruelest month. I disagree; I think March is. Muddy roads and gray skies predominate. Flowers are scarce. We have April to look forward to, but if you pot up some daffodils next November for forcing, you can at least have some indoor blossoms now, in March.

Everyone I know is thinking about spring — despite the fact that we could still see snow and sub-zero temperatures before we see tulips. This might be a good time to take an inventory of your tools to see if you have everything you need, and buy the ones you need. This is also a good time to clean up, sharpen and oil the tools you have.

First, a list of the basic tools all gardeners need:

1. Garden fork. This is a straight-handled tool with four flat tines that can be used to loosen the soil for planting, or to dig out things like a clump of daylilies. These come with either fiberglass or wood handles, and I always choose wood. Both handles can splinter over time, but an oiled and well-maintained wood handle will outlast fiberglass. I have some wood-handled tools still in great shape after over 50 years of regular use.

2. Pointed shovel. I like the short D-handle shovel better than those with a long straight handle, but that is for you to decide. The short-handle model is lighter weight and has a nice grip. A pointed shovel digs into the soil more easily than a straight-blade spade.

3. Garden rake. This is the rake that has short tines spaced an inch or so apart. It is good for smoothing the soil or forming raised beds.

4. Lawn rake. There are a dozen different styles, and all will do the job. The old-fashioned bamboo rake is nice, but the tines do break after a while. Plastic rakes are lightweight but also break after a few years. I prefer those with metal tines.

5. Drain spade. This is a shovel that has a blade that is long and narrow (16 inches long, 5 inches wide). Great for transplanting, it can get all the way under a plant to help you pop it out of the ground.

6. Hand tool for weeding. There are plenty, but I like the CobraHead Weeder best. It is a hand tool shaped like a curved finger, and can loosen roots from below while you give a gentle tug from above. I use it to loosen the soil for planting, too. They are available at garden centers or online at cobrahead.com.

Tools require some maintenance, and this is the time to sharpen, clean and oil them if you didn’t do it last fall. Fiberglass handles generally require no maintenance, though I suppose you could take off any rough spots with steel wool or sandpaper.

Wood-handled tools should never be left outdoors, but most of us forget occasionally; strong sun or rain will damage them and give them a rough surface. If the handle is very rough, use a piece of sandpaper and lightly sand the handle, tip to stern. Wipe it well with a rag before applying oil. For less damaged handles, rub with fine steel wool. Don’t sand a handle that has a urethane finish unless you intend to take it all off — but you can use steel wool on it.

Next apply a coat of boiled linseed oil. I like to heat the oil until hot before applying, as this is a fairly thick oil, and heating it will help it to penetrate the wood. I use a paintbrush or a rag to apply the oil.

Let the oil sink into the wood, which might take overnight or just a few minutes, depending on the grain and how dry the wood is. Never try to oil a wet handle. Apply a second coat and let dry. Then rub it down with a fine steel wool, labeled 000 or 0000. This will take off any bits that are raised up by oiling and burnish the wood.

Next look at the steel of your tool. If it has crusted soil on it, clean it first with a stiff brush — either a wire brush or even a stiff bristle brush. If it is rusty, clean off the rust with your steel wool.

If you have a well-used shovel, it is probably dull. It is easy to sharpen it, but you will need a good 8- to 12-inch file, either a rough or medium file, often called a mill bastard. Be sure to get one with a handle, as some only come with a short pointy part and require you to add a handle.

Shovels should only be sharpened on one side, the side that faces into the hole as you dig. The back side will stay flat. Push your file across the shovel blade in only one direction, away from you. You may wish to clamp the shovel to a saw horse or bench so it stays in place as you work, or push it down on the bench and file with one hand.

Go from the edge of the curve to the middle in one long stroke of your file, and repeat, keeping count of your strokes. Turn the shovel around and do the opposing edge, using the same number of strokes. Keep your file at the angle set by the manufacturer if that is evident. If not, an angle of about 45 degrees is good. That will make a sharp cutting edge, but not be so thin that it will get dull quickly. You don’t need to sharpen the sides. And don’t worry: You can’t ruin your shovel even if you have never done this before. Just keep at it, and stay consistent.

When you have the shovel sharp, turn it over and you probably will be able to feel burrs on the back side — little bits of sharp metal. Clean those off with a few flat strokes of your file.

Finally I take a rag with linseed oil and wipe the shovel blade. Some people use machine oil to oil their tools, but I don’t want petroleum products in my soil, even a little bit.

Every gardener has her own favorite tools. If you’re a rookie, visit a good gardener and ask for a tour of tools. Then go buy what you need. And remember: Sharp tools work better than dull ones.

Plant your seeds indoors

By now many gardeners are fed up with winter: icy sidewalks, misplaced mittens and dogs that need to go out at 5 below zero. But it will soon be time to start planting seeds indoors, so you might want to start getting ready now.

It’s true that greenhouses and garden centers do a nice job of starting plants if you are not interested in babying seedlings along for 8 to 12 weeks. I do let them start some for me but find that there are plenty of things I want to grow that are not available. So I do both. I start some now and buy others later.

In order to be successful with your seed-starting efforts, you will need supplemental lights. If you try to save money and just start a few seedlings on a sunny windowsill, you will most likely be disappointed. Even under the best conditions, direct sun only reaches your seedlings about six hours a day, much less than they need.

Fluorescent lights are the least expensive solution to the need for supplemental light. My fixtures are 4 feet long and use two T-8 tubes each. The fixtures are available at hardware and big box stores, and cost from $16 to $40 each, depending on where you buy them.

T-8 tubes use 32 watts of energy per hour, while older-model T-12 tubes use 40 watts. This year I bought some LED bulbs that fit my 4-foot fluorescent fixtures but use only half the electricity. I’m switching over to LED for the sake of the environment, but as the tubes cost about $8 each, I am spreading out my purchases over a few years. If you want to make the switch, make sure the package says they do not require any rewiring of the fixtures (older models did require that). One nice thing about the LED lights is that they don’t break if you bump them hard or drop them. Select lights that are 4000K or 5000K color spectrum, which are close to daylight color.

I use a biodynamic calendar called Stella Natura to help decide on planting dates. It uses the sun, moon and stars to determine the best time and day to plant four categories of plants: flowers, fruit, leaf and root. It also has “blackout” days when nothing should be done. I am not 100 percent convinced that this calendar really works, but have done some informal experiments planting seeds on their suggested days, and on blackout days, and it seemed to make a difference.

Read the seed packages carefully if you are new to starting indoors. Onion-family plants and peppers take a long time to develop, so most people start them in early March, though I started my onions and scallions on Feb. 20 this year. Tomatoes I start around April 10 — I don’t want them to get root-bound or too tall before I put them out on June 10. If you plant outside earlier, start seeds earlier.

Not everything needs to be started indoors. Most root crops are direct seeded in the garden, though you can start beets indoors. Some flowers hate to be transplanted — larkspur, for example, which also needs cold temperatures after planting. Lettuce can be planted indoors or out, or both. I like to get some started early indoors. All the cucumber family plants I start indoors four to five weeks before planting outside as this protects them from striped cucumber beetles when they first germinate.

An important key to success with your seedlings is to water properly. If seeds dry out before they germinate, or when they are tiny, they are likely to fail. On the other hand, keeping seeds soggy all the time can lead to root rot. Check them every day. If you see the planting mix turn a lighter color or if it feels dry to the touch, water. I water with a dilute solution of fish or seaweed fertilizer once a week.

To get seedlings to wake up and start to grow, I use heat mats sold for that purpose. They plug in and gently warm the seed flats. But I only use them until most seeds have germinated as too much heat for seedlings is bad. For one thing, the “soil” dries out fast with extra heat. I prevent that by using clear plastic covers sold to fit over the flats, creating mini-greenhouses that hold in the moisture.

I mostly use flats with 32 cells per trays that are roughly 9 by 18 inches, although others are sold with up to 108 cells per flat. I want plenty of room for roots to grow, so I buy cells that are as deep as I can find. I plant two or more seeds in each cell, just in case one seed does not germinate. For onions, I plant three or four seeds per cell, as they don’t mind a little crowding.

Most seeds germinate about 90 percent of the time. For tomatoes I sometimes snip off one plant when young, other times I let both grow, and separate them and replant both in bigger pots when they are 4 to 6 inches tall. For me, it’s hard to kill seedlings by snipping them off and I can always share seedlings with others.

Garden centers and catalogs sell a variety of stands with lights for growing seedlings. Most are quite expensive. You can also go to my website, gardening-guy.com, and search for “Building a Plant Stand.” That will give step-by-step directions for building an inexpensive A-frame plant stand that will hold six flats, and have room below it for four to six more flats on the floor.

Starting seedlings is not rocket science. It involves some investment, but the lights and plant stands last nearly forever. And, as the bumper sticker says, “Growing Tomatoes Is Cheaper than Therapy — and You Get Tomatoes!”

A few ideas to get you started

When I was a young man my mailbox was often blessed with seed catalogs at this time of year. Now? Not so much. Back then I pored over them. I drooled over the listings. I wrote checks for small amounts and mailed them off to the companies offering the best-sounding varieties.

Now? Most seeds are sold online. Yes, my favorite feed-and-grain store, some hardware stores and the local food coop still sell seeds over the counter. And I do get a few catalogs in the mail. But seeds are largely sold through the internet.

One company that still sends me a catalog in the mail is called “Seeds from Italy” (also at GrowItalian.com). I’ve been following this company, which is based in Lawrence, Kansas, since a friend of mine bought it in 2011. His son, Will Nagengast, just took over and I called him to chat a bit after I got his catalog.

According to Will, the American palate is just discovering bitter vegetables. Italians, however, have been eating and enjoying those distinct flavors for a long time. So they feature many vegetables that are not commonly sold by other seed companies; they market seeds from Italy.

One I have tried is Cima di Rapa or broccoli raab, which I often see in cooking magazines, but not at the grocery store. It is unpleasant unless cooked, but cooked it is much like broccoli. It does not form a big head like broccoli, however — it’s all side shoots.

Do you like arugula? They sell five kinds, including a wild arugula (which can seed in if you let it). Then there are a dozen kinds of radicchio, including a pink-leafed one (Radicchio del Veneto) that Will says is very popular. Never grown radicchio? It can be eaten raw in a salad, or fried with bacon and shrimp, or put in a stir-fry or soup. Grilling or cooking it makes the flavor sweeter. Most varieties are red-leafed and round, but some are elongated like romaine lettuce.

I’m ordering seeds for a winter squash Will recommended: Butternut Rugosa. He says it is much larger than the Waltham butternut I normally grow: up to 30 or 40 pounds! He said it keeps for up to four months in a cool, dry place. He oven-roasts them and then freezes most of these big squash. Will uses the sweet, creamy meat for making homemade ravioli.

Fruition Seeds in the Finger Lake Region of New York State was started in 2012 by Petra Page-Mann and Michael Goldfarb. They are fully organic farmers, and most of what they grow are heirloom seeds, but they have developed a few varieties themselves through their breeding program. They encourage their customers to save seeds and use their own. I called Petra recently to see what they have added to their seed line.

August Ambrosia is a short-season watermelon that Fruition developed over a six-year period in collaboration with Cornell University. They tested it each year with visitors to the farm to get just what people wanted: sweet, juicy melons that, even if planted in June, will produce ripe melons in August. The rinds are thin and the seeds are small. Petra told me on the phone that you can eat the seeds — or have fun spitting them!

“Food is so social. Growing and sharing food is how we remember to be human,” Petra told me. So she welcomes visitors to the farm, and shares her food — and her fantastic enthusiasm — with her visitors. And she learns what appeals to her customers, which is good business.

Fruition sells seed for two interesting cabbages: Kalibos is a deep purple cabbage, cone shaped, with big hips. According to the website, it is best as a fall cabbage; sow in early or mid-July for best results. You can seed them in six-packs in early July and transplant them into the garden in early August at two-foot spacing. Harvest them in October and November to get heads of optimal size and sweetness.

Mermaid’s Tale is a cross between Kalibos and early green cone-headed cabbage. Each one is unique in color, shape and flavor: lime green to emerald with lavender to burgundy veining. Sharp or subtle flavor.

Another specialty of Fruition Seeds is their “Hope is a Verb” dahlia. Each seed is unique and each flower is different, made from innumerable crosses of dwarf and semi-dwarf collarette-style dahlias. Petra explained to me that dahlias have eight sets of chromosomes, and consequently have many ways of expressing their genes. The plants are 2 feet tall or less, with blooms 1 to 3 inches across. She said they are fabulous for short seasons and lower light conditions. I shall start some.

Lastly I shall order Spotlight Snow Peas from Fruition Seeds. Some will be green, some purple, some mixed colors. They are very early (or late if planted in early August for a fall crop), very sweet, and 3 feet tall or less. Petra says they taste great and only take 52 days to harvest!

Every company has something unique and wonderful. Buy your seeds now, as some seed companies will sell out before summer. And if you haven’t tried starting seeds indoors, I’ll tell you about that next week.
