Hurrah! Mother Nature says it’s time to plant the peas.

It’s important to wait until your soil is adequately warm to plant seeds or transplants. If it’s too cold and damp, the seeds will rot, or germination will be delayed. Don’t ask me how I learned these facts.

I planted ‘Oregon Sugar Pod II’ and ‘Cascadia.’ It’s always dicey, planting peas, because our springs can go from cool to blazing hot in just a couple of weeks. Fall crops tend to perform better, but I try every year for a good spring batch.

Planted some ‘Bloomsdale’ spinach, flat-leaf Italian parsley, and bok choi as well. Hope that harvest looks as good as this one.

A quick garden postcard: fresh January salad (and recipe)

Lettuce 'Freckles'

Lettuce ‘Freckles’

I peeked under my row cover yesterday to see how the greens are doing. What could be better than a fresh salad from the garden in January?

Lettuce grows quickly. This variety, ‘Freckles,’ can be harvested in 55 days from seed. The critical thing is to ensure it has steady moisture. With our unending rain, that hasn’t been a problem.

I’m going to toss this with a tablespoon each of dried cranberries and pecan pieces. I’ll top it off with some parmesan cheese, and dress it with olive oil, red wine vinegar, salt, and pepper. I may throw in a few leaves of fresh thyme.

Try it. You’ll like it.

Zone 7 Gardeners, Start Your Seeds!

If you live in USDA Hardiness Zone 7 or warmer, it’s time to sow seeds (indoors) of

  • Onions
  • Hot peppers
  • Artichokes
  • Celery

If your onion seed is left over from last year, pitch it out. Onion and leek seed seldom remains viable longer than one year.

How to sow vegetable seeds:

  1. Fill a clean, sterile flat with a soilless mix. Ideally, choose one made for seed starting.
  2. Moisten the mix and tamp it down firmly.
  3. Sow the seed according to package directions.
  4. Cover lightly (if indicated) with sand, perlite, or grit to thwart damping off.
  5. Water lightly again.
  6. Cover with clear plastic and place in a warm, well-lit location.
  7. Monitor every day or so to maintain good moisture levels. When seedlings emerge, remove the plastic covering.

If you’re looking for good varieties to try, consult Cornell’s Vegetable Varieties for Gardeners website. This citizen-science database includes reviews of thousands of vegetable varieties by gardeners across the country. You can filter results by your state, frost-free season, or soil texture.

You won’t transplant these outside for some time yet, but these crops need an extra-long head start. Aren’t you glad you have some indoor gardening to do when it’s so cold and nasty outside?

Controlling flea beetles in the fall garden (help wanted)

I didn’t get row cover on my beans in time this spring, and the flea beetles found me.

Flea beetle is something of a catch-all term used to describe several species of beetles (not all of the same genera), all of which are tiny (1/16 to 1/10 of an inch long), that live in the soil and cause mayhem in North American gardens. They adore feeding on your vegetable plants, and can reduce a favorite crop to smithereens if not dealt with promptly. One treatment won’t suffice: They can produce four generations or so in a warm-climate growing season. Overwintering adults typically emerge when temperatures hit about 50 degrees (10 C). In recent years, it’s been 50 degrees at Christmas.

Here is my quandary: Their preferred cuisine is cruciferous, which happens to be what I need to get planted soon. Most winters are mild enough here that greens and root crops may be harvested year-round if grown under horticultural fabric, but that means getting seedlings and transplants off to a good start, starting now.

Row covers can be effectively employed to exclude flea beetles from pristine soil, but (clearly) that’s not what I have. Installing row cover where an infestation has already occurred just traps the beetles inside, keeping them safe from predators while they devour your spinach. Row cover must be sealed tightly all the way around to be effective, by the way.

Trap crops come highly recommended. “Plant a crop of mustard greens!” the gardening literature exhorts. Alas, the trap crops are what I want to eat this winter. Kale, collards, mustard greens, broccolini, radishes, tatsoi, arugula. These are the seed packets sitting on my desk, awaiting my decision. I fear that planting a trap crop, even far away (relatively speaking) from the vegetable bed, will only encourage more of the little punks to move in and feast upon everything in sight.

The garden literature also recommends scouting newly planted beds and counting the beetles as they arrive. This presumes the gardener can count insects best differentiated from dirt with a hand lens before they jump to the safety of the earth. Anyone who has brushed against a plant infested with flea beetles has seen a spray of tiny bugs fleeing the scene of the crime. Who can possibly count them in situ? Even if the gardener manages to hunker silently down and get a view of the action, must she hold her breath to avoid disturbing them? What if she needs to sneeze? (It’s fall pollen season, you know.)

I don’t want to spray if I can avoid it. I have been known to pull out the neem oil from time to time, but it’s only moderately effective against flea beetles.

What to do, then?

Possible solutions to flea beetle infestation

I’m tempted to try one or a combination of the following. Have you had success with any of these?

1. Diatomaceous earth. DE is a fine powder made of fossilized remains of diatoms, a kind of algae. When used as an insecticide, the powder absorbs components of the waxy coating of insects’ exoskeletons and causes them to dehydrate. It’s critical to obtain food-grade DE for this application to be effective.

2. Interplanting with garlic. Garlic is a moderately effective insect repellant when sprayed on plant surfaces. I have to plant my garlic somewhere; I suppose it may as well go between my rows of kale.

3. Parasitic nematodes. To read about parasitic nematodes is to discover another of Mother Nature’s horror shows. Employing them can be a bit tricky, because the gardener must get the correct kinds of nematodes (families Steinernematidae and Heterorhabditidae, and some species are picky about who they infect); time the application to coincide with a larval stage of the target species; and keep the soil moist, not too hot, and not too cold.  On the plus side, they don’t infect birds or mammals.

Given my warm climate, and extrapolating unscientifically from the graphic above, I guess I might be able to interrupt a larval cycle if I went out tomorrow and applied the nematodes…maybe?

Please send your advice, post-haste.

Crop experiment: Growing shallots

Have you ever grown shallots? I haven’t, but I’ve just ordered my first sets to plant this fall. I love the way they taste, so I’m excited to try them.

Shallots (Allium cepa var. aggregatum) are botanically related to onions and garlic. They are native to Central Asia and have a very mild, delicate onion flavor that is wonderful in salads and egg dishes. They grow like garlic, forming clusters of offsets (small bulbs that form off the main bulb). Inside the bulb, shallots are layered like onions.

I’m growing French gray shallots (Allium oschaninii), which some consider to be the “true” shallot, and French red shallots, the ones most often found in grocery stores and markets. The red shallots are supposed to be easier to grow, but the gray ones allegedly have better flavor. The red shallots grow larger; the grey produce prolifically.

Like other root crops, they like well draining soil amended with lots of organic matter. My raised beds should suit them very well, as they contain equal parts composted manure, decomposed bark, and washed sand. I’ll perform a soil test before planting to make sure the pH is appropriate. I cannot plant them until mid-October, but if I wait until then to order them, they won’t be available. I made that mistake last year.

What crops are you trying out in your fall garden this year?
