Cover Fall Edibles Now

In my Seattle garden, fallen leaves are drifting up around the edges of my vegetable beds like Technicolor waves lapping at the shore. Time to deploy the season extension.

This time of year, nature is getting ready to go dormant. Despite the occasional warm, sunny day, the weather pattern is changing. Shorter days (and longer nights), cooler temperatures, glorious rain, from drizzle to downpour, all signal the change in plants. Growth slows down. Cell walls begin to thicken in the plants, mirroring our defensive layers of fleece and wool.

Stave off the inevitable decline in your vegetable garden by covering those plants that are actively growing. The ones that will feed you salad this fall can be nursed along for a few more weeks if covered with a cloche or a cold frame.

Three devices

Three season extension devices protect fall and winter crops: hoop-house cloche, triangle tunnel and cold frame.

The root crops that are going to be overwintered will be aided by a blanket of garden fleece, also known as floating row cover. Later this fall, you can pull off the FRC and cover those beets and carrots with a cloche, giving them more protection during our coldest time.

The last of the summer basil crop is nursed along under the dome hot cap.

The kale, cabbage, broccoli and Brussels sprouts will benefit from a top-dressing of compost and straw mulch, between the rows and around the plants. This step can be taken for all the fall and winter veggie plants, but isn’t as necessary for those under a cloche or cold frame until the weather really reaches our daytime winter temperatures of 45 degrees. Still, I often do this now around my salad greens too, just since I’m out in the garden with the straw at hand. It’s often more pleasant to do it on a nice fall day than try to wait for a break in the winter rains that will take hold in November.

The main reason to do this season extension and mulching work is to protect our plants from the colder temperatures, pounding rains and desiccating wind.

A few weeks ago I put in a late batch of lettuces and raddichio into a long hoop-house cloche. With the unseasonably warm weather, I’ve been able to take that off for days at a time, and the veggies are nearing harvest. Now that rains and cooler weather are predicted, I’ve put it back on again.

Often at this time of year I’ll set up the cold frame over a bed with starts. It’s amazing to check the soil temperature inside the cold frame and in the bed next to it. Inside the bed, the temperature of the soil will be well above 60, while in the open garden the soil temperature is inching down toward the mid-50s. Capturing that warmer soil temp, keeping it from dropping so fast, is a key benefit to season extension.

cold frame

My Twinwall cold frame is keeping the fall salad greens robust.

Also this week we’ve had a couple of days of significant rain. At times, it’s come down pretty hard. A soft rain is great for watering the beds, and I open the season extension devices for a few hours in early afternoon if a light rain is coming down. The best situation is a nice soft rain for an hour or two, followed by a clearing and light breeze, so the plants dry out. Regular moisture on the leaves and stems of fall veggies can promote rot. If I can’t get the timing right to open the season extension during a light rain, I hand-water the beds as needed.

And I always keep the devices closed during a heavy rain. Over time, heavy rains will compact the soil, leach out the nutrients, and reduce those soil temps — all things I’m trying to avoid. Score another benefit for season extension.

floating row cover

Fall beets and carrots are growing nicely, and bug free, under a layer of floating row cover.

The winds are also gusting this time of year. Combined with cooler temperatures and rain, the wind can be hard on tender vegetable crops. The worst effect is when it blows the top layer of

A couple of unusual kales that were struggling are getting a boost by being covered with glass hot caps.

mulch away from the base of the plant, exposing the plant’s fine root system. Those roots will dry up, making it tough for the plant to survive, much less grow. Such stress will invite pests, and can trigger the plant’s desire to bolt and go to seed.

One final idea concerning season extension: what’s good for the plants is also good for the pests. In this sense: the pests love the warmer, drier location too. I’m picking a lot of slugs and snails out of my season extension devices right now, and off the plants. I need to be diligent about this, because they’re all drawn to the warm place with plentiful food. As the temperatures continue to drop they’ll become less of a problem, but right now, I need to pay attention if I want to keep those fall crops around for my autumn dinners, and not just be feeding the pests.

new cloche

I’m having fun with my commercial-made cloche. The long single-row device has an internal wire frame and zippered vents with mesh.

Fall in the maritime garden is a time to appreciate our weather. The change is usually not abrupt, giving me a chance to also adjust my own pace to the slowing rhythm of nature. But the decline into winter is inevitable, which is another lesson. At this pace, it seems more possible to stay in the moment, enjoying the color and patterns of those fall leaves as they naturally mulch the margins of my garden.

 

Holiday weather blues? Don’t despair, plant!

It was the best of weather, it was the worst of weather.

Memorial Day Weekend in Seattle will bring up brooding Dickensian thoughts. What should herald the start of summer here often disappoints. When all you want to do is take your kids hiking, go to a music festival, wheel off on a nice long bike ride, or simply just host a BBQ, you have to look to the skies, and judge the depth of the grey.

Why, then, would I start this post so optimistically? The best of weather, by what standards? Well, my Brussels sprouts love it.

Brussels sprouts seedlings

These Brussels sprouts, sown on May 7, got potted up to 4″ pots this week, and will be ready for the garden by mid-June.

At this stage of the year—what I call mid-spring in my catalog of mini-seasons—I am engaged in a garden tug-of-war. Part of me wants to grow the fattest red tomato on the block, so juicy it drips down my shirt. I want big pepper plants heavy with spicy pods. Some years, I even yearn for a stand of corn.

But my muscles yank me back to cool-season crops too, and possibly more to reality. Mid-spring is a time for struggle on the part of my tomato plants, and the peppers can stay under cover or fight for their survival. But it’s a glorious time of growth for cool-season vegetables. They celebrate this dreary holiday weekend weather like twirling hippies at a Phish concert.

And now, when you’re focused solely on getting those hot crops of summer in the ground, let the cool breezes of a maritime spring clue you in: time to give those long-season vegetables of next winter some love.

Tomatoes and Peppers in Greenhouse shelves

The tomatoes are getting leggy, and the peppers aren’t getting any younger in their pots. But the greenhouse shelves work great!

Here’s a quick list of what to sow now in pots for planting out in June and July:

  • Purple sprouting broccoli
  • Brussels sprouts
  • Cabbage (winter)
  • Parsnips

And here are some things to plant directly in the garden in mid-July for fall and winter eating:

  • Collards
  • Jerusalem artichoke
  • Kohlrabi
  • Rutabaga
  • Turnip

There are many other, shorter-season veggies that can be sown later in the summer and into the fall for fall and winter eating, but for right now, instead of trying to jump-start summer, skip over it and look to fall. Put on a Dead record and rave on with your brassicas.

Final presentation at City People’s

Many Seattle gardeners are mourning the impending loss of City People’s Garden Store on Madison, which got the land sold out from under it for the inevitable mixed-use development. It was the first nursery I used when I moved to Seattle in the mid-1980s, and I still hold it fondly in my mind. When it closes at the end of this year, it will be a major loss for city gardeners. I will miss it.

I’ve been giving a series of edible gardening talks there for years, and my last talk is coming up next weekend. On Sunday, June 5 at 11 a.m. I’ll do a seminar on starting long-season vegetables. Hope you can join me, support the store with some purchases and give City People’s a proper send-off.

My Edible Seattle Column Debuts

It’s all about edibles in my garden. And in my writing. And on this site. So I was delighted to be offered the task of writing a new column for Edible Seattle called (you probably guessed it) The Edible Garden.Edible Seattle cover

Now on newsstands and in subscribers’ hands is the excellent first issue of 2016, which includes the column’s debut, and a lot of other great stories.

My first topic covers something of perennial amazement to me: why our winter vegetables get sweeter after a frost. I dug into this topic during the cold, rainy days of early winter.

I’d love for you to buy the issue–or better yet, subscribe to the magazine–and read the entire thing for yourself. But I’ll give you a hint as to what I found: the plants are making sugar as a defensive mechanism against the cold. There’s a lot more to it than that, and I hope you’ll find it as fascinating as I did.

Only one problem: we haven’t yet had a frost in my garden. It’s been relatively warm and wet. But hope springs eternal. Mind you, I only want a little hoar frost, not the killing deep-freeze kind. But I think that we’re safely beyond that.

If you’re hankering for some photos of frosty vegetables like the one below, see my post from exactly three years ago when we had a nice, sweet cooling spell.

Broccoli

Event alert

Here’s a warming event to spice up a winter weekend: Edible Seattle and Metropolitan Market are sponsoring a Whiskey and Chowder Festival. Coming to Fremont on Feb. 4, it will showcase 7 local distilleries and 16 restaurants, who promise a variety of chowders and soups, but also other tasty treats. A unique event that looks like a winner.

Early Winter in My Outdoor Refrigerator

A good rule of thumb for winter edibles is to have your vegetables large enough for harvest by mid-December, which I achieved with some of my plantings. Carrots, beets and kohlrabi are ready anytime.

The goal is to use the garden as an outdoor refrigerator, planting crops that will store well in situ and can be harvested as needed. Broccoli, Brussels sprouts and kale are on that list.

With leafy greens, I have some ready now, and some smaller plants under good protection that will hopefully give me a very early harvest when the days begin to get noticeably longer a month from now, well after the solstice.

Here are some images of my garden right now.

Carrots

The soil for these carrots could have been lighter. Heavy soil with rocks can lead to deformed roots. Still, how sweet they are!

November Tasks: Slow Gardening

Grab that sliver of sunlight between showers and get out into the garden. Fleece up and tidy the shed on a rainy day. Scratch out some thoughts on next year, with notes on this year’s successes and duds.Garlic and favas

There are some November tasks for us Maritime Northwest gardeners. But this season is also a time to take it easy and practice “slow gardening.” Moving at slug speed on these chilly wet days seems most appropriate.

Granted a glorious Sunday afternoon last weekend, I rallied to rake out the last open space in my vegetable beds and plant garlic. Three varieties, six rows, 48 cloves. That should keep us in spicy sautés for most of next year.

The rest of the open space got filled up with favas. I had a box full of the thumbnail-sized beans saved from last spring’s harvest. They sat for six months waiting for this occasion, so I could no longer deny them their special purpose: Get under the soil and send up next year’s crop!

Favas are one of the few vegetables whose seed will sprout in our chilly November soil. Garlic, of course, needs a little chilling to trigger its emergence. I’ll see the fava shoots in a few weeks, but the garlic won’t poke through the straw mulch until January. It always warms my heart to see it during that coldest month, just as I am starting to notice the days lengthening beyond the solstice. Another season beginning.

A few more tasks that are getting some slow action on these short November days:

Sorting the bees. Yes, you read that right. I’ve had a box of Orchard Mason bees wrapped loosely in a mesh bag on my basement shelf since I brought them in in early fall. Now it is time for them to be transferred to the refrigerator for the winter.

Bees in tubes

Orchard Mason bees are in their cocoons. I’ve removed them from their paper sleeves to clean and store the cocoons in the refrigerator for winter.

Bee cocoons

The mites have mostly been cleaned off these Orchard Mason bee cocoons.

The task is simple and rewarding. First, I open the stacked grid that holds the bee nesting tubes, paper sleeves in which they laid their eggs and mudded up the holes. I pull out the paper tubes and carefully peel them open to reveal the bees in their cocoons. (Since the eggs were laid in the spring, the eggs have hatched, the bee larvae have eaten the pollen deposits left with their eggs, and the larvae spun their little cocoons.)

Along with the bees in those tubes are a couple of interlopers that need to be removed. Spiders have laid their eggs in some of the tubes. No big deal, except I don’t really want those hatching on my basement shelves.

More concerning are the mites: hundreds of mites have glommed on to the bee cocoons. If left with the cocoons, they would attack the bees when they emerged, and decimate the population.

Fortunately, right now the mites and the bees are pretty dormant, so as I pull the cocoons away from the paper tubes, I brush off all the mites.

The clean cocoons are then counted and stored in a plastic bottle inside a plastic bag in my refrigerator. The bottle has some vents cut in the lid, and the plastic bag contains a damp paper towel that I’ll refresh from time to time. Refrigerators are low-humidity places, and my bee cocoons need a bit of moisture to survive.

Weeding the beds. Winter weeds grow more slowly, but so do your vegetable plants. And with less nutrition available in the soil, your winter vegetables don’t want the competition from weed roots. I clear a space at least a few inches around the base of each winter veggie. I also run the fork along the edges of the raised beds and pull out any grass that is encroaching. It seems to really spread if left to take hold over the winter.

Some of the less harmful, more beautiful weeds like viola tricolor (Johnny Jump-up) get left in the beds between the plants. They can be good filler to shield the bed from winter rains, and I can use the flowers to brighten up my winter salads.

Mulching the fall and overwintering veggies. After I weed, I try to tuck in some straw or other light mulch around the base of the plants.

This provides a number of benefits:

  • keeps heavy rains from compacting the soil
  • prevents wind from drying out any partially exposed roots
  • prevents the soil from becoming too dry if we don’t get rain
  • prevents weeds from sprouting.

And it looks nice!

Broccoli mulched

Servicing the watering devices. I garden in a mostly mild winter climate, but sometimes we’ll get a hard freeze or a week of snow, so I need to protect against freeze damage.

First, I make sure my drip irrigation system is drained to avoid having the pipes burst. (Water is one of the few things that expands when it freezes.) I also check the downspouts and gutters to make sure there’s nothing clogging up the system that fills my water catchment. I clean and store my ceramic bird bath so it doesn’t crack. Finally, draining the hoses and storing them in the garage each winter will help them last many more years.

I appreciate the slower gardening days of winter. I can review some of these tasks as I peer through a rain-streaked window, looking to the western sky for that actionable opening of blue.
