Charging Into Winter Gardening

If you’ve tackled a big garden project on a hot summer day, you know how fast you can drain your internal batteries. The heat seems to sap it out of me. But as weird as it may seem at the height of summer, right now we should be recharging our garden’s batteries with some new plants for winter.

Peas in a pot

I planted peas in this pot next to my compost pile, and now they’re ready to be moved into the sun and under a trellis.

In the Maritime Northwest, August and early September are great times to plant. I’ll tell you what seedlings I’ve got in pots and in the ground right now, and what you can get from the nurseries in the coming weeks if you don’t want to sprout your own.

If you can start from seed, I recommend it. It’s amazing how quickly seeds will sprout in a summer garden. Parsnips, which are notoriously finicky seeds, sprouted in just four days during one of our recent warm spells. And they came up in such a prolific little forest that I had to get down there and do some serious thinning.

I’ve also started Brussels sprouts, purple sprouting broccoli, beets, carrots, peas and arugula.

Beets

Beets and other seeds will sprout fast in warm summer soil. Be sure to thin to proper spacing. These beets need to be thinned to 4 inches apart.

Of course, with warm days and no rain, I’ve been hand-watering the seedlings to supplement my automatic watering regimen.

What to start now

Greens:

  • Arugula
  • Asian greens (mustards, bok choi, tatsoi, shungiku)
  • Corn salad (aka mache)
  • Cress
  • Endive/radicchio
  • Lettuce (Marvel of Four Seasons, Continuity, Merlot, Red Oak Leaf, Green Deer Tongue, Forellenschluss, Little Gem… so many – plant a rainbow salad!)
  • Swiss chard

Brassicas:

  • Broccoli (fall)
  • Broccoli raab
  • Cauliflower
  • Kohlrabi
  • Kale (choose Lacinato, aka Dinosaur/Palm Tree, the best tasting of all)
Dino kale

The best tasting kale, and very reliable in a mild maritime winter.

Roots:

  • Beets
  • Carrots
  • Radish (winter varieties, like Black Spanish)

Alliums:

  • Leeks

More alliums go in later this fall, but you can plan now. Leave space for garlic and shallots.

Seeds or starts?

Most of these plants can be directly sown into the garden, and many of them can now be found as starts in good quality plant nurseries. I always recommend planting root crops only from seed, not transplanting.

If you’re starting from seed and want more control over the plantings, consider starting many of these in pots. It helps you keep a better eye on the seedlings to keep them well watered. You can move a flat of pots into the shade on hot days, or even protect them under some hoops and floating row cover for extra shade and to maintain soil moisture.

When space comes available in the garden and the plants have grown enough to establish hearty roots, you can transplant them. Remember that transplanting in summer is pretty stressful on young plants. Do it on a cooler, cloudy day if you can, and pay extra attention to watering until they’re showing new growth. You can also move the starts to a very large pot and keep them growing there until harvest.

Peas under a trellis

We’ll have plenty of peas for fall. I planted this batch along the house where spring salad greens had been.

More for fall

Also, plan ahead to fill the space when summer vegetables are done. Purchase a supply of cover crop seeds (often sold as a blend, which is a good way to go) and have them on hand to throw down when you pull out the tomatoes, peppers, squash, etc. You can plant a cover-crop blend up until late October.

If you have crops coming out even later, plant fava beans. They can be sown into early November and will reliably sprout in that late-fall cold soil.
