Fresh Greens to Harvest from Fall through Winter

Fall and winter offer a second chance to grow all the delicious greens and wonderful roots we savor in spring. They’re even easier to grow, thanks to decreasing weed pressure and reduced need to water. Many winter greens, like kale, collards, and spinach, even taste sweeter in fall as they concentrate sugars to withstand colder temperatures.

Our garden is brimming with greens ready for harvest now, as well as younger plants that we won’t harvest until early spring when they will grow rapidly as the days begin to lengthen.

Elliot Coleman coined the term “Persephone Days” for the period when there is less than 10 hours a day of sunlight and plant growth slows to a halt. Typically November 21st through January  21st, or a little longer due of outside ground temperatures. So what you see in the garden now is what you get until early February for practical purposes, unless you are growing under cover in a greenhouse, cold frame or low tunnel.

With an extended drought and weeks of record breaking highs, 2016 was a really tough year for establishing our fall crops. In many cases we had to do a third succession planting to get the beds full of thriving plants. In the case of spinach and kale, our last and most successful sowing was in early October. For an idea of what and when we sow most years read our blog post on Summer Sowing: Continuous Harvest All Summer into Fall or look at our Southern Exposure Fall and Winter Growing Guide.

So let’s take a look at some of what we have green and growing in the garden on “Black Friday Weekend 2016”:

Kale, collards, and spinach are our largest plantings for winter greens because of their versatility in the kitchen and dependable winter hardiness. Because our earliest succession plantings had spotty germination we have a lot more plants from the later sowings. Luckily for us the unusually warm temperatures continued into November so we have nice full beds of Abundant Bloomsdale spinach and Lacinato Rainbow kale going into December. Fortunately half grown ”juvenile” plants often survive the winter and last longer into the spring. In addition to the heat and drought our collards were also attacked by grasshoppers in August so the remaining plants are smaller than usual at this time. Heirloom collards are survivors so I expect they will do well and start vigorous growth again in early spring.

We have already harvested many of our oriental greens for stir-frying and to make Kimchee, but our Tatsoi greens are still looking and tasting great. In winter we enjoy the shiny dark green leaves in salads, stir-frys and soups. One interesting thing with the spotty germination on some of our early sowings is how large the plants can get in fall and still be sweet and tender.

Another favorite green for us and many others in our region are Creasy Greens and their cousin from grower Frank Morton of Wild Garden Seeds in the Northwest, Belle Isle Cress. They are lightly spicy and crisp in winter. Take care as they will naturalize if left in the garden to produce seed.

Let’s not forget Arugula, another winter salad favorite.

We also grow a lot of winter lettuce. I especially like red varieties for the deep color they develop in winter. Outredgeous and the Wild Garden Lettuce mix are favorites that have been joined by the heirloom Crawford, a Texas winter salad Lettuce.

We still have some winter roots in the ground: carrots, beets, salsify, parsnip and winter radishes. We have potatoes and sweet potatoes in storage.

Maybe we can look at what we still have canned, dried, fermented and frozen sometime soon. Until then enjoy your garden.

Transplanting Tomato Seedlings

Most of you have probably already transplanted your tomato seedlings, but here at SESE we do it a bit later than most. Why? Because we want the vast array of tomatoes we grow for the tastings at our late August open house and at the Monticello Heritage Harvest Festival in September to be ready for picking just at the right time for those events. We’re growing more than 70 varieties for you to come and taste!

Here’s the technique we use for quick and successful transplanting of tomato seedlings:

After hardening them off for a couple weeks in our cold frames, we’re ready to take them out to the garden. For us, this means lots of careful labelling and mapping to keep all those varieties clearly separated!

Step 1: We start by spreading hay thickly over the whole area where the plants will go. This serves to keep the ground cool, hold moisture in, and choke out weeds, and in the long term it adds organic matter to improve the soil. If you try this, make sure you get hay that hasn’t been treated with herbicides or pesticides. You’ll also want to get hay that’s been sitting for a year or so, giving all the seeds a chance to have sprouted and died, or you’ll be growing grains alongside your tomatoes.

Step 2: Make a nest in the hay at each place where you want a tomato to go. Space them about 4 feet apart and make each nest about a foot in diameter, pushing the hay away until you can see the ground.

Step 3: Dig a hole at the bottom of the nest, toss in a double handful of compost, and mix the compost with the soil you have loosened.

Step 4: Gently pull the seedling out of its container and lay it on its side at the bottom of the hole you’ve dug, all the way at one edge of the nest space. This way you can cover not just the root ball, but also a good portion of the stem with soil. You want to bury a third to a half of the plant. Tomatoes will grow roots along any portion of the stem which is underground, and this method gives you a much sturdier root structure. Be careful that the sideways portion of the stem is supported by soil so it doesn’t break.

Step 5. Cover the root ball and stem portion with soil and press it down firmly. Good soil to root contact is essential to get the plant sucking up water and nutrients right away. Then pull the hay back into place all around the stem of the plant, tucking it in cozily. Finally, give it a good watering and watch your baby grow!

If you do come to the Heritage Harvest Festival, here are a few of our top picks to look out for:

  • Rutgers 250 This is a brand new variety which brings added durability to a flavourful old heirloom and we plan to add it to our 2017 catalog.
  • Matt’s Wild Cherry This one is always a favourite at tastings, an intensely sweet wild cherry tomato originating in Mexico.
  • Garden Peach A delightful novelty tomato disguised as a peach.
