Spring Veggie Updates
Posted by piedmontgardener in Favorite Plants, Greenhouse growing, piedmont gardening on March 10, 2015
Sorry for the prolonged silence, folks. I’ve been too busy to write, thanks to a break in the weather. After the snow melted, we got 1.28 inches of rain, which caused my creek to flood.
Although our vegetable garden is at the top of our hill, a good 200 yards or so up from that active floodplain, the raised beds were still unworkable for a while. I actually hit ice in the first one I tried to weed before the rain came! But my property is blessed with sandy loam instead of Carolina clay, so my raised vegetable beds became workable a few days ago, and just in time. My greenhouse was overflowing with eager spring lettuces, spinaches, and assorted other greens.
I rid two vegetable beds of their winter weeds. The crimson clover I had planted to prevent their takeover was killed by our super-cold February temperatures. But the henbit and chickweed thrived. At least they are relatively easy to remove.
I was hoping to direct-sow some carrots, but they need a minimum soil temperature of 55 degrees, and as of yesterday afternoon, my soil temperature was 48 degrees. Maybe next week, if the clouds will part to allow the sun to warm the beds.
I know they don’t look like much, but that’s a lot of potential salad in that shot. I left a bare spot in the middle for a few carrots, when the soil temperatures allow. I mulched the new transplants with the last of the mushroom compost we had delivered last season. I finished off that pile, so we’ll be getting more delivered as soon as the weather allows.
The kind folks at WordPress who created and maintain the blog software I use provide me with many useful statistics, including a daily list of search terms folks are using that lead them to my blog. From this, I know that a number of Piedmonters are starting to think about spring gardens and what they should plant. So I thought I’d share with you what I’m growing this year and why.
First, gardening — especially vegetable gardening — is a trial-and-error endeavor. Even if you grow the same varieties every year, you won’t get the same results. Weather, diseases, insects, seed quality, pollinator availability, varmint invaders — these are just a few of the variables that make it impossible to be sure you’ll end up with what you envision. That being said, I’ll tell you what usually works for me.
This assumes, by the way, that your garden area is already prepared and waiting. If you’re just now contemplating breaking ground for a spring garden, forget about it — unless you’re going with a container garden. The soil is too wet, and you don’t have time to get it ready for a spring garden. If the soil dries out soon, you could still grow summer crops in new ground, but it will take some serious work on your part. I wrote about soil preparation here.
What I Grow
I like to experiment, so most years I try at least a few varieties that I’ve never grown before. Sometimes the hype in the seed catalogs leads me astray, but sometimes I strike gold. That’s how I found Sweet Treats tomatoes — a cherry tomato variety I can’t live without now.
In the spring garden, there’s really only one kind of onion variety that grows well in our area. Onions are tricky, because most are sensitive to the amount of daylight they receive. The only kind I find worth growing are Yellow Granex onions. These sweet onions remain reliably mild. Mine rarely obtain the enormous size of the ones I see in the grocery stores, probably because I never manage to give them as much water as they want. But we always end up with a nice crop of medium to small sweet onions that store very well in our cool basement.
Spinaches come in two forms — smooth-leaved and savoyed-leaved. Savoyed-leaved varieties have wrinkly leaves. For me, the savoyed-leaf types seem to grow better, but if I plant early, I usually get at least some smooth-leaved leaves worth eating too. Spinach in my garden bolts at the first sign of heat. An 80-degree day is enough to get it to start sending up its seed stalk. When that happens, the leaves turn bitter and inedible very quickly. I always look for varieties that are described as “bolt-resistant” or “heat-tolerant.” Even so, the spinaches are done well before the lettuces every year in my garden.
This year, I’m trying three different spinach varieties. Tyee is one I grow every year, because it always seems to be the last to bolt. It is a savoyed-leaf type. I’m trying another variety, Crocodile, of the same leaf type. This year, the smooth-leaved spinach I’m trying is Corvair. I purchased all three varieties from Johnny’s Selected Seeds.
OK, I admit I always go a little nuts with the lettuces. Back in January when I’m perusing catalogs, I’m nearly always craving fresh greens. I look at all the pictures, read the enticing descriptions — and I just can’t seem to stop myself from ordering an array of selections. A few tried-and-true varieties are always on the list, but I’m always on the lookout for new varieties touted as heat-tolerant, productive, and tasty. My selections this year:
- Annapolis — This is a red romaine that I grew last year and loved. I think it was the last lettuce to bolt last year.
- Coastal Star — This a green romaine that also holds up very well in the heat. In the most recent growing years, the romaine lettuces have outlasted all other types.
These are the only two lettuces I ordered from Johnny’s this year, because I had already been tempted by the Baker Creek Heirloom Seed catalog to order a few of their offerings:
- Merlot — a leaf lettuce reputed to be “the darkest red lettuce in existence.” Red lettuces, as with red/purple fruits, contain beneficial phytochemical nutrients. Baker’s claims it’s very bolt-resistant. Time will tell.
- Slo-Bolt — a green leaf lettuce with a name that tells you why I’m trying it. The Baker’s catalog claims it to be an excellent variety for the South. That’s me.
I also love the bitter speciality greens so often featured in fancy salads these days. The arugulas, mustards, and assorted other brassica relatives are very quick to bolt in my spring garden. So I limited myself to one mix from Johnny’s called Ovation Greens. They did produce a nice mix, which I interplanted in the bed with the lettuces and spinaches. I also got a complimentary packet of Tuscan Baby Leaf Heirloom Italian Kale from Renee’s Garden. The packet says it is a fast-growing variety designed to be picked small for salads. Free seeds for salads? You know I had to try it. I suspect it will bolt quickly; I’ll keep you apprised.
I started a few dill plants in the greenhouse when I planted the greens. Like the greens, dill bolts in the heat, and I wanted to try to give some an earlier start than I can provide with direct sowing (that soil temperature thing again). Interplanted with the greens are a few, slightly spindly Superdukat Dill plants from Johnny’s. This variety is supposed to produce more leaves than flowers, and it is the leaves we use in cooking. I’m hoping the plants will look more lively after they adjust to their new surroundings.
Interplanted with the onions are a few Red Ace beets that I started in the greenhouse. They germinated quite well for me. I’m hoping that I’ll get bigger beets by having plants in the ground this early.
I am absolutely gambling on the weather by transplanting now. I plan to cover the greens bed in a tent of heavy-weight garden fabric to protect them from freezes. But I won’t be able to get to that for a few days. If the temperatures dive more than predicted, I could be in trouble. But the prospect of an early, prolonged salad season was too tempting to ignore.
After I finished planting yesterday and took pictures of the results, I walked around the yard to document some of the early-blooming trees and shrubs beginning to explode with color. I’ll share some of those shots soon.
For those of you wondering about summer garden plants, if you’re growing from seed, you should not wait any longer to start your tomatoes and peppers. I’ll share my progress with those veggies soon too.
So much to do and show and tell. Surely, it must be almost Spring!
