Year-round vegetable gardening

In the Southeastern U.S, we have ample sunshine (over 10 hours a day, except for about a week and half around the winter solstice) for growing vegetables year-round. 

In 'normal' winters, we can grow kale and collards that sail through normal freezes, as well as garlic and onions.

In exceptionally cold winters (like the last couple of years), unprotected hardy greens have suffered significant frost damage.  But even this year, mustards have re-emerged looking pretty leafy in protected walled gardens like the kitchen garden next to the visitor center at the Garden where I work.

I've been delighted with my winter greens experiment in the unheated hoophouse at the Garden --totally amazing.  I'm planning to sow a short season sequence of greens in the pots and bags of soil mix, as well as chard and beets, just to see what happens.

More winter vegetables

A comment on a post made in December about winter vegetables and an after-school program this afternoon have me thinking about change-outs in vegetable garden beds.

I had harvested some Tuscan and redbor kale, spinach, and purple mustard from the kitchen garden next to the visitor center to show a group of 2nd graders from a nearby school learning about eating and growing vegetables as part of a Clemson University Healthy Campus Initative outreach program.

It was a fun program; three Clemson students in a nutrition class had talked to the kids at their school last week about eating a rainbow of colors and will do a follow-up next week.

We sniffed herbs, sampled flowers from the bolting collards, looked at lettuces, saw strawberries in flower, and tasted garlic chives. Another three Clemson students (student athletes) helped with the kids, too, and were great (they're part of a group called Tigers who Care -- we're the Clemson Tigers in our athletic programs.

I showed them my flat of spicy salad mix (they all tasted young purple mustard leaves), spinach seedlings, and had them 'plant' in dry potting mix seeds of scarlet runner beans and yard-long beans.

We're about two weeks out from our average last frost date.

The variable temperatures and moisture levels have the kales and collards bolting (some years they last until May). So we'll be pulling out (and giving away) the greens in the visitor center vegetable garden over the next couple of weeks, to make room for the warm-season transplants.

Spinach, lettuce, mustard, and mache

In the main vegetable garden this winter and spring, I'm avoiding planting brassicas (kale, collards, arugula, mustards, etc.) to dampen the root-knot nematodes (even though I have a few overwintered collards).

I'm also only going to plant nematode-resistant tomatoes and peppers when warm weather comes.

So, garlic, onion sets, lettuce, mache, and spinach are what I've planted so far. The garlic went in last fall, with the onion sets being stuck over the last couple of weeks, and the greens just sown.

I also sowed a couple of flats of spicy mesclun and radicchio, as well as large containers of spinach and mesclun. These can all be protected if a hard frost threatens. It's been mild for the last few days; not as warm as last week, but pleasant in the afternoons.

I've got all the beds ready to sow greens and early cole crops in the satellite garden, and hope I'll be able to snag the woodchuck who will be undoubtedly hungry as s/he emerges on warm days!

And my seed potatoes should arrive soon.

Fall vegetables

The recent rain, (slightly) cooler weather, and the greening up of the garden overall have me thinking about sowing greens for fall. It certainly seemed way too hot in August to contemplate sowing broccoli for transplant and I certainly wasn't able to get chard or beet seedlings to survive, although maybe the squirrels nibbled them.

But I've had tremendous success in previous years (photo above) with a variety of greens in fall -- Tuscan kale (also known as dinosaur kale), different sorts of red kales, radicchio, and perpetual spinach (a sort of beet). Mizuna, red mustard, chard, and argula are all great, too, if there aren't too many late cabbage butterflies. Lettuces are beautiful in fall, and the really hardy winter varieties can make it through heavy frosts in mid-winter, if conditions are right. I also need to start sowing the small Violas that are so much nicer than pansies, and less demanding and take cuttings of Spanish lavender, to increase my supply.
