Inspiration, Seed Swaps Focus of Upcoming Events

The season starts early for a cool-season gardener. Not just the planting season, but the speaking-at-events season too. I’ll be at nurseries, garden shows and seed swaps in the next month, evangelizing about getting your edible garden underway.

Seed swaps first

This Saturday I’ll be hosting the Great Seattle Seed Swap up on Phinney Ridge. This first one happens on National Seed Swap Day, and is the first of four area swaps — three in Seattle and one in the Snoqualmie Valley.

Brussels sprouts in pots

I’ll also be at the Snoqualmie Valley swap on Feb. 6. At both, I’ll be giving a short talk as well as staffing a table for Q&A and seed research.

The King County Seed Lending Library has received a wonderful donation from the Organic Seed Alliance of Port Townsend. They sent copies of their recent book, The Seed Garden, for each of our locations. What a resource! It’s comprehensive, easy to use for research and a great read. The book was co-published with Seed Savers Exchange, another essential resource.

OSA also sent a generous supply of their locally adapted Abundant Bloomsdale spinach seed and phacalia tancetifolia, which has a flower that’s a pollinator magnet.

Come to the swaps to see the book and get the seed!

Nurseries coming

Before the swap on this Saturday I’ll give my first nursery presentation of the season, up at Swansons Nursery in northwest Seattle. It will naturally be about starting seeds, but also focus on soil-building at this time of year. And I’ll throw in some ideas about where to get inspiration for this year’s garden.

I’ll do another talk at Swansons on Feb. 27 on special techniques to get the most out of your veggie plot.

In March I begin my annual four-class series at another great Seattle nursery, City People’s Garden Store. I’ll head down to Madison Valley for the first talk on March 12 about starting the early-season garden.

Portland on tap

I’m getting out of town, too, with a pair of talks at the Yard, Garden & Patio Show in Portland. Walking the human-scale display gardens at this show always energizes me to try something new in the garden.

Get a book

At all the talks and shows, I’ll have my two books, Cool Season Gardener and Edible Heirlooms, available for sale, and I will happily personalize your copy with a signature.

I’m doing a special signing at the Northwest Flower & Garden Show. Find me at the University Book Store booth #211 on Friday, Feb. 19, 3-4 p.m.

Hope to see you at an upcoming event!

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.

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.

Beets

A winter beet harvest is just what the doctor ordered.

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.

Pest Hunting: A Brassica Task

My many fall and winter Brassicas are sizing up nicely, but the ones not tented with floating row cover are showing a little chewing and some curling leaves. The culprits are cabbage butterfly larvae, snails and aphids.

Predator insects are still plentiful in the fall, but these pests can stunt the growth of young plants at a time when they need to be powering into winter with a strong growth spurt. To ensure robust, healthy plants, I am going hunting.

Cabbage butterfly

The larvae of the cabbage white butterfly or imported cabbageworm (Pieris rapae), often called the cabbage moth, are my first prey. Mostly what I’m finding right now are the slender green worms. They can hide — almost — by stretching out for an afternoon nap in the stem of a young leaf. They are further protected from my predatory grasp by secluding themselves inside the youngest leaves, the curled and furled ones sprouting from the plant’s center.

Cabbage butterfly larva

Cabbage butterfly on leaf

Can you spot the green cabbage butterfly larva on this leaf? Hard to get a good camera focus, but it’s on the lower right edge.

Carefully, so as not to snap the tender growth shoots, I unfurl the rolled green shoots and lightly scoop through the inside with a fingertip.

Then I bend back the plant’s slightly larger leaves and unfold them one at a time, checking the base of the stem for the pale green body. Finally, I flip the leaf over between fingers and eye the back, in case one of them is on the move. (I look also for the elongated eggs, white or yellowish, on the undersides of the leaves. Those get squished too.)

Just the act of inspecting the plant can cause these critters to fall to the soil below, where they would pretty promptly inch under a leave and climb back on the plant, so I scan the soil surface too.

These pests can go through 3 to 5 life cycles per year, and can be in the garden from April through October. The jerky white butterflies with black wing dots flit around from plant to plant. Amazingly, they mate in the air. Their eggs take 4 to 8 days to hatch, and the green worm larvae lives for 3 weeks before pupating, where they cocoon themselves for a couple more weeks before emerging as a butterfly and beginning again.

I think — I hope — they’re on the year’s last life cycle.

 

Aphids

Green and grey aphids are a regular presence in my garden, and I’m finding small colonies on the broccoli, Brussels sprouts and kale. They take up residence on a stem or in the folded end of a leaf, and as they suck the juices out of the tender leave edge, it curls, providing them a cozy home.

Ones hiding in the leaves are fairly easy to spot, as the leaves also turn slightly purple on the edges when attacked in this way.

Aphids curling leaf

A colony of aphids on a fall broccoli start has caused the leaf to curl due to their feeding.

predator and aphids

Predator to the rescue! This native bee, just peeking over the leaf edge, happened to be checking out the aphid supply as I took pictures. I did not see him feed on them, but I hope he came back for dinner.

Again, my preferred method is to gently curl back the edges of the leaf and expose them. As they are also soft-bodied insects, they also will get quickly smooshed in between a thumb and forefinger. There is a little inevitable damage to the leaf area that was their home, but it’s much preferable to letting them form a stronghold there and begin to feed farther down the leaf and fill the stem, as they would like to do.

Aphids on Russian Red kale

These aphids crowding the stem of a Russian Red kale are doing plenty of damage.

When the aphids have colonized the base of a set of leaves, or the stem of a plant, a hard spray of water from the hose, straight down into the center of the plant, will wash them all off and drown a lot of them. Most of the rest are too weak to climb back onto the plant. I find that I need to return and do this again in 3 days to make sure I’ve gotten them all.

 

Snails

I used to see a lot more slugs, but the garden ecosystem has evolved to be more hospitable to snails. They are moving from my dying summer plants into my winter beds. It’s happening at a snail’s pace, but that’s fast enough for me to put on my camo gear and start stalking them.

These guys are a lot more visible than the others, as their brown shells stand out on a green leaf, even at a smaller size. They especially come out on a cool or rainy day, or right after dark.

Sometimes I’ll find their gelatinous, round white eggs in a cluster on the edge of a bed, usually near a rockery or some other good hiding place.

Snail eggs

These snail or slug eggs were found about six inches down along the inside edge of my stacked-stone raised bed.

But the hatched snails, or slugs, are most often found on the underside of the leaves, and they are quickly transferred to the underside of my foot on the path. Score another one (or ten) for the big guy.

These creatures are fascinating, and are all part of nature’s plan. And I don’t mind sharing a bit of my food with them. But this time of year, when the tastiest things on their menu are the young plants that will comprise my winter dinners, I am in a less permissible mood. Fall is for hunting.
