More about Trenching-in Tomatoes

By Jan Hersey

Regarding Peter’s TWIG post on planting tomatoes, here’s what I did with tomatillos (same technique for tomatoes).

Remove lower leaves from tomato plant.

Dig about a 14-in trench, 6-8” deep on the end where root ball will go, sloping the trench up to original soil level at opposite (stem/leaf) end. Place tom as shown below, gently bending up leaf end, supporting it with and securing it to a small stick.

 

Cover root ball and stem with soil, then create a moat around the former trench. Trim off more leaves if needed. Ultimately, you’ll want a foot of leafless stem (helps prevent getting water on leaves) before allowing plant to branch into 1-3 stems).

 

Weight down an empty gallon plastic pot with some stones and place it on the soil between the root ball and growing stem. Throughout the season, water into the pot, which will slowly release the water into the trench.

 

Spring Update, and Brassicas

Crops planted earlier in April are starting to take off. The first potato leaves are pushing up at the bottom of their trench and will need repeated hilling around the stalks to make more spuds and less foliage. The bush snap and tall snow peas are knee-high and starting to flower as they climb their trellises. The storage onion seedlings and the onion sets are 6-8 inches high, while the first beds of leek transplants are being installed.

In the hoop house all the tomato and pepper plants are finally in, the cucumber transplants are adding leaves, and the direct seeded cukes are starting to pop up. I have a few eggplants, but I do them in large pots filled with commercial soil to avoid the verticillium wilt disease that has built up in the garden soil over the years.

Finally, the early cabbage, broccoli, and cauliflower starts, as well as the long-term Brussels Sprouts, are starting to push up against the floating row covers.

A Note on Brassicas: the 4-Season Crop

In the coastal Pacific Northwest’s moderate maritime climate vegetable gardeners are able to a grow one or more variety of brassicas year-round.

Cabbages start in the spring with a variety such as Early Jersey Wakefield, continue on through the summer with large heading varieties for slaw and sauerkraut, while long-standing red cabbage matures slowly over 100 growing days. Hardy Fall/Winter green cabbage such as January King, planted in mid-to-late summer, keep sprouting through our mild winters. Other cabbage varieties include the crinkly Savoy, as well as the various types of Oriental cabbage.

Broccoli is much the same, with early, mid-summer and fall crops. There are also two purple over-wintering varieties: the Valentine broccoli that heads up in late February or March, even amidst brief snowfalls, and the Purple Sprouting broccoli that slowly develops as a leafy bush all the winter and then produces masses of small edible buds in early spring.

Cauliflower I find is usually just one crop in summer, with both the standard white variety and the green Romanesco with its circular pattern of pointed buds. Brussels Sprouts, started in the spring, start to mature in late fall, and stand tall all winter.

With all these possibilities to fill up the garden space it is vital to rotate your cabbage crops to avoid build up of soil disease. Do not plant brassicas where they were grown the prior year. There are also endemic insect threats, especially the cabbage root maggot fly, which will destroy the roots of young brassica seedlings. The cabbage butterfly, the familiar white floater, produces caterpillars deep inside the cabbage head, but the damage is usually minimal. And aphids will hide in the soft tops of Brussels Sprouts in both summer and winter, but can be deterred by spraying with a mild solution of detergent and water.

Protect all brassicas initially against insects with floating row cover, well-sealed on the ground on all sides, and held up by wire hoops over the beds. I leave the cloth protection on until the plants are at least half grown or more and can survive on their own. Check often under the cloth to remove weeds, snails or slugs. The final reward is when you remove the cover to reveal the luxurious maturing crop. Almost like magic.

Beans

With the warm weather in May, once the soil temperature is above 60 degrees, it is time to plant beans. At the large vegetable garden I share with another family, we plant three 8-foot long rows of Blue Lake pole beans, a reliable northwest variety that is good both fresh and frozen. In the past we used tall metal fence posts supporting string or netting to hold the vines. This year to make it easier to do the initial set up, and the removal of the dead vines in the fall, we are using galvanized 4×8 metal cattle guard fencing set on end. Once the beanstalks get to the top, and want to keep on growing out of easy reach,  I redirect them laterally on horizontal sticks laid between the the tops of the bean walls. The result is a covered arbor; the beans hanging down over the inner walkways, easily picked like overhanging fruit.

I like pole beans because they can be harvested continuously over a long period of time. The trick is to keep them picked while they are still tender, before the beans swell inside the pods and become inedible. Unless you want to save seed for next year, be sure to remove any bean pods at the bottom of the stalk that start to turn brown, to keep the plant producing new beans at the growing tips at the top.

 

There are many types of bush beans, which generally produce a more concentrated crop over a shorter period of time. My personal favorites include Burgundy beans, dark purple beans that turn bright green when cooked, along with tender French filet beans, a gourmet variety that is picked when very thin and delicate. This year I am trying Venus, a white Italian cannellini bean for either fresh use or when dried as the standard dry bean for minestrone soup.

With our longer and warmer summers these days, it is increasingly possible to harvest dry beans in the maritime Northwest. Several pioneer-era varieties of beans that will dry successfully before the fall rains were carefully saved by Puget Sound area gardeners over the years. The short-season varieties have been rediscovered and are now beginning to be available commercially. The WSU Agricultural Research Extension in Mount Vernon is also doing trials on other dry beans for local use. Grow your own vegetable protein.

Finally, there are Scarlet Runner beans, well-known for the red flowers that attract hummingbirds and for the vigorous vines that will easily ascend the tallest pole you can supply. As dry beans, the large, dark purple and black beans are very meaty tasting . A unique trait is that a mature Scarlet Runner bean that falls to the ground and gets buried in the soil will sometimes overwinter and sprout in the spring.

Let’s Save Seeds for Local Food Security

by Sequoia Ferrel

Posted May 6, 2020

In such uncertain times our thoughts turn to making sure we’re secure in basic necessities such as food and clean water. The best way to achieve food security is to have a robust local system where the majority of our food needs are provided through small farms and home gardens.

As gardeners and farmers we’re dependent on having access to seeds for the plants we want to grow. Since the Covid-19 crisis, there’s been a high demand for seeds and many have sold out. So, in order to work towards developing a strong local food system, it’s imperative that we start with the seed supply.

TF&F hopes to start a seed-saving network in which participants will each be responsible for growing and saving certain seeds based on their experience and preference. Then, before the next growing season (two seasons for biennials) we’ll be able to share the seeds so everyone can have a full garden worth of seeds and more to spare.

What follows is just a basic overview of seed-saving. I’m aware many of you already know all this stuff.

 

To get high-quality seed involves a little more than just waiting for something to flower and set seed and then  gathering it up. Especially if we’re selecting for food crops, we want to choose seed from the healthiest plants that perform best for us under our growing conditions.

To start, we must be willing to set aside some garden space for our seed crops (if they’re biennials, that will involve this year and next also).

We also have to use open-pollinated seeds and not hybrid seeds (which won’t make new seed true to its parent). Seed catalogs will let you know whether the type of seed you’re buying is a hybrid or not.

Seeds can also be either self-pollinated or cross-pollinated. For those of you new to seed-saving, it’s best to start with self-pollinated crops as they can be grown fairly close to other varieties of the same species without fear of cross-pollination. Some of these are peas, beans, lettuce and tomatoes.

For those of you more experienced or up for a challenge, you can try growing crops that cross-pollinate, which may be pollinated by insects or wind. If you choose this option, you’ll need to know not only to keep other varieties in your garden from flowering at the same time but you’ll need to be aware of other gardens and farms that may be within your isolation distance. Some seed crops just can’t be grown here — for instance carrots will cross with Queen Anne’s Lace — which as far as I know grows everywhere in this area.

There are also 3 other main categories of plants: annuals, biennials and perennials. Annual seeds can be saved the same year they are planted. Biennials, such as the cole crops and root crops, will make their crop the first year and need to be kept alive into the second year, which is when they put their energy into making seed.

I’m willing to head this seed-saving network and if anyone wants to help, you’re more than welcome! My idea is that initially everyone interested will notify me, and the group, as to which seeds we want to save, and then we’ll  make adjustments so that we don’t have, for instance, 10 people saving lettuce and no one saving beets.

Once we decide who grows what, I can send you specific info concerning your seed choices. I’m not an expert but I do have reference materials, including The Organic Seed Grower by John Navazio, which is the definitive reference. I also have a few seed screens and fan, and can help with the seed cleaning when we get to that point.

Growing Tomatoes

by Peter Heffelfinger

Posted May 4, 2020

I plant a mix of cherry tomatoes, beefsteak types for slicing, Italian sauce tomatoes for freezing, and always a few heirlooms to try out for intense flavor or unique coloration. Once the soil has warmed to a toasty 60F inside the hoop house, usually by the end of the first week in May, it’s time to transplant. This year I have an improved metal soil thermometer that looks just like a large meat thermometer from the kitchen, but geared, of course, for much lower temperatures. Well worth the expense to know exactly when the ground is warm enough for heat-loving plants. I put a large pot or a box over all new transplants to shield them for a day or two to reduce shock, especially on the sunny days that have been more prevalent the past few years.

Growing tomatoes involves some form of staking, wire cages, or a vertical string assembly. When I was a kid back in the hot and humid East Coast, we just let the vines spread out on the ground, with the suckers sprouting laterally in all directions over a wide area, just like a pumpkin patch. With smaller gardens, and tomatoes inside greenhouses or hoop houses in the Northwest, growing them vertically saves space. A support system also helps prevent diseases, such as the blights that come from foliage contact with soil, and of course elevates the clusters of fruit, making them easy to pick.

 

The big issue is pruning: removing suckers on a regular basis. Otherwise you end up with a tangled mass of too many stems, too much overlapping foliage, and smaller, less numerous fruits. For me, the best advice comes from local NW Garden maven Cisco Morris: select 3-4 main stems and then let them rip. Prune out any additional long skinny stems that start creeping up from the base.

Most importantly, make sure the first set of stems is 4-6 inches above the ground to avoid contamination. Then, as the plant bushes out, trim off any lower branches of leaves that start to touch the ground. No leaf contact is the order of the day, to prevent disease.

As the bushes fill out, it’s also vital to thin the crowded upper areas of leaves for better air circulation and to allow sunlight to penetrate into the central area of the plant to ripen fruit. Be vigilant with your pruning. Remember that this is a rambling, tropical ground vine being reoriented to growing on a vertical support.

I prefer the tall conical tomato cages that allow the branches to drape over the hoops. I tie up a series of cages in a conjoined row so that the bed becomes one long connected tomato hedge. To keep the heavy clusters of ripening tomatoes from breaking their fragile branches, I run lengths of rope along the sides, connected to the wire cages, to hold them up. A bit untidy looking, but I think of it as a seasonal espalier.

Compost at Home: Food Digester Method

by Callie Martin

posted May 2, 2020

Gardens offer us a hopeful perspective. “They give us a way to connect to something immediate here and now and watch it grow,” says Dr. Rupa Marya, a professor at the University of California San Francisco’s Medical School.

One of the best ways to bring your home garden to life is through the creation of healthy soil. Did you know that all the leftover food scraps create conditions conducive for life to grow? They can when you make them into compost.

Since food scraps from the kitchen can attract rodents in the backyard, it’s best to begin using a method specially designed to break down food scraps, rather than tossing them into a traditional, open-air compost pile.

Building a Food Digester

One of the simplest ways to compost food scraps is in a sunken garbage can. The can should have a tight-fitting lid and holes punched into the sides and in the bottom. A galvanized can works well for this project, you can also use a five-gallon bucket. Here is the step-by-step:

  • Drill or punch about 20 drain holes that are one-quarter to three-eighths inch diameter, in the bottom of the can.

  • Drill 20 more holes in the sides of the can, but only in the lower third, which will be covered by soil.

  • In a well-drained spot, dig about 15 inches deep and set the can into the hole. Then, push the soil back around the sides and tamp it down with your foot or a shovel.

  • To get your digester ready for food scraps, gather shredded paper, dry leaves, or other chipped woody debris and layer it on the bottom of your digester, several inches thick.

  • Follow this by sprinkling two to three cups of garden soil onto the brown materials. This “inoculates” your digester with all the oxygen-breathing microorganisms that encourage healthy, odorless decomposition.

 

Your new digester is ready to use!  Collect food scraps, storing them in a container in your kitchen and once or twice a week, throw them into your food-scrap digester. A good way to keep fruit flies from getting into the bin is to layer the top with a thick piece of cut-out cardboard or newspaper. Placing a handful of shredded paper or dried leaves atop each addition of food scraps will keep mold or odors from developing and help the food scraps break down evenly. No worms need to be added to your digester. They’ll find their way in through the holes and help the composting process. Depending on your household food habits, compost should be ready to harvest in 6-12 months.

Integrated Pest Management Resources for Home Gardeners

Jane Billinghurst, WSU Skagit County Extension Master Gardener volunteer

Posted April 29, 2020
[To receive an email when the Fidalgo Grows! blog has a new post, enter your email in the blog subscription area to the right.]

In a recent post, I outlined the amazing free bulletins WSU Extension provides for people wanting to grow vegetables at home. Here are the two main links where these resources, tailored specifically for growing conditions in western Washington, can be found:

http://gardening.wsu.edu/home/

https://pubs.extension.wsu.edu/general-gardening

After you have planned and planted your garden, the next item on your list is to protect your hard work and keep your vegetables healthy.

The bulletins help here. There is info, for example, on dealing with voles and using row covers to keep insects away from your veggies.

But there’s another way to access info about dealing with pests and diseases that are common in western Washington. If you suspect a particular bug or disease, you can go to Hortsense and check out what the damage caused by those bugs and diseases looks like. The site then describes the biology of the pest or disease, lists non-chemical management options available to you, and provides general links to pesticide information.

WSU Extension also has a bulletin that explains how Integrated Pest Management works—that is, choosing the least invasive way of dealing with pests and diseases and keeping your vegetables healthy. Where and how you plant and your choice of what to plant all make an enormous difference to how healthy your vegetable garden will be. If you understand IPM (both in the planning stages and after you’ve planted your vegetables), you can set yourself up for success and have fewer pests and diseases to deal with in the long run.

WSU Skagit County Extension Master Gardener plant clinics are here to help if you’d like more info about how best to deal with a plant problem. The Master Gardeners (MGs) are not offering in-person plant clinics at the moment, but they’re taking inquiries via email (skagitmgplantclinic@gmail.com). You can also leave a phone message at 360-395-2368. Please provide the location and a detailed description of the problem, plant, or insect. Send digital photos if possible. Also, provide a phone number in case the MGs have more questions. You can find more information here.

Tomato Season Opens!

By Peter Heffelfinger

Posted April 21, 2020
[To receive an email when the Fidalgo Grows! blog has a new post, enter your email in the blog subscription area to the right.]

Early May is the time to transplant tomatoes, perhaps the most wished-for home vegetable in the relatively cool Northwest.The raised beds inside my 40-foot long plastic hoop house have been warming up for several weeks. Tomatoes are a tropical vine that needs warm soil to start out as well as a minimum nighttime temperature of 50F degrees in order for the flowers to set fruit. And of course, warm daytime temps to fully ripen.

Where I garden even on the warmest days of summer the onshore wind starts to roll in every afternoon around 4 pm and the temperatures start to drop. Each evening the hoop house needs to be closed up to maintain a constant overnight warmth. Conversely, the house needs to be opened up early in the morning before it gets above 80-85 F inside, which can happen quite suddenly on a sunny morning with no wind. If it gets too hot, say above 90F, the flowers will drop off. In addition, condensation forms each night on the ceiling; the droplets need to air dry in place instead of falling on the plants and causing disease. And, for watering I let the chilly well water sit in a large tank for a few hours in order to warm up a bit. Warm soil, warm air, and slightly warm water, allows a tropical plant to grow well in the cool maritime Northwest.

What with watering, pruning and staking, and watching the temperature gauge, tomato production is a full time gardening chore. But large, ripe beefsteak tomatoes, Italian Romas for sauce, and handfuls of cherry tomatoes for eating out of hand are worth all the work.

Note on transplanting using the Trench Method:

I use 1-2 foot tall starts (pinch off any flowers that may have appeared). If you dug a 2 foot deep hole in the ground, the roots would be buried in cool soil. To keep the roots close to the warm topsoil, and to propagate additional root growth, make a lateral trench with one end 8-12 inches deep, but with a gradual slope of dirt rising at 45 degrees up to the other end. Gather a small berm of dirt at the far end, rising 1-2 inches above ground level. Add a standard organic fertilizer for vegetables, mixed into the soil at the bottom of the trench.

Trim off the lower suckers and branches, leaving intact the top three branches and the main growth bud at the top. Make a small puddle of water at the deep end, put the root ball into a small depression in the mud, lay the bare stem gently on the inclined plane, with the stem of the top 3 branches resting against the berm at the other end. Use a thin bamboo stake to gently secure the exposed top branches in a slightly vertical position. Fill in the trench and continue the berm around the entire root and stem planting area. This is the permanent watering crater.

Make sure you water consistently above where the roots are, not at the stake. Water by can or hose gently onto the soil, without splashing dirt up onto the leaves, which can transmit disease. I place the gallon plastic pots the tomatoes came in, with a few pebbles inside for stability, at the center of the crater and then water directly into the pots to avoid splashing dirt on the leaves. The water also drains out slowly into the crater instead of arriving all at once and possibly breaking through the berm. Never water from above; keep the foliage dry at all times to avoid the dreaded tomato blight.

Happy Tomatoes!

[To receive an email when the Fidalgo Grows! blog has a new post, enter your email in the blog subscription area to the right.]

Now is a great time to embark on new projects or brush off old skills. Vegetable gardening might be on your mind. There’s lots of info in books and on the internet, but how do you know what really works and whether the advice is appropriate for where you live?

The researchers at WSU Extension have put together a series of free downloadable bulletins to guide you through what works best in western Washington.

Here is the link to one way of accessing them: http://gardening.wsu.edu/home/. There’s a handy menu on the left-hand side of the page where the bulletins are sorted by subject, including Garden Construction, Organic Gardening, Pest Management, and—of course—Vegetable Gardening.

Alternatively, you can go directly to the WSU publications site at https://pubs.extension.wsu.edu/general-gardening and browse through the offerings or type in key words for the subjects that interest you.

There are a lot of resources, so what’s a good way to sort through them?

An excellent place to start is “Home Vegetable Gardening in Washington,” which includes information on preparing your site, planning what to grow, when to plant, and ongoing maintenance.

Maybe you have a specific crop in mind? In that case you can look for bulletins on carrots , peas, or many other vegetables and small fruits.

Perhaps you are interested in attracting beneficial insects to your vegetable garden? Or using organic products?

If you don’t have a vegetable garden, you might have a strip along the roadway or space for a straw bale or two in your driveway. There are bulletins to help you grow vegetables here, too.

There are also publications on general topics such as soils and fertilizers and composting.

All the advice is free, science based, and specifically tailored for our area, so dive in and happy gardening!

 

It All Starts with the Soil

TWIG (“This Week In the Garden”) posts will appear weekly, on Mondays, to help you know what to focus on for a successful growing season.

This Week in the Garden (TWIG #1)

April 20, 2020

​

Peter Heffelfinger

If you are new to gardening this year it is important to remember that everything begins with your soil. While Fidalgo Island is blessed with a moderate climate for year-round vegetable production, there are challenges in finding a good garden site. 

The first few gardens I had here lacked any real layer of topsoil, the healthy, friable layer of dark dirt that is the basic need for growing a crop. Due to the Ice Age glaciers and various former river beds, we have layers of gravel and clay or concrete-like hard pan that can lie right under a layer of regular soil. In the worst scenario, one needs to build an enclosed raised bed filled with new topsoil. It is vital, though, that the hard sub-soil be loosened up first with a spading fork to provide good drainage. Soggy soil means poor growth, more pests, and eventually dried-out unbreakable clods. Note: do not invert the gritty subsoil to the top layer; keep it at the bottom, underneath the topsoil.

 

I rake up the available dirt into raised beds 6-8 inches high to warm up the soil in spring and to drain better in the winter. It is important to regularly add composted organic matter to keep the soil loose for aeration and good tilth. Note: compost alone does not supply large amounts of balanced nutrition to your plants. Amendments are needed, whether from well-rotted manure or organic commercial mixes. I use a combination of both. In addition, given that our native soil is acidic, a dusting of slow-acting dolomite lime (not fast-acting industrial lime that may burn your plants) is also required (except where you plant potatoes, which prefer acid beds).

 

Given that we are well into spring, I would concentrate on planting early, cool-weather crops, such as lettuces, radishes, and greens such as spinach and Bok Choy, which will readily go to seed in summer heat. Once the soil heats up in early to mid-May, it is time to plant beans, squash and other warm weather varieties. I hold off on corn until June 1st. For tomatoes, peppers and cukes I use a grow tunnel for added heat during our cool night mists that roll in off the Sound. We are in a maritime climate, even as our summers get warmer and drier.

Fidalgo Grows is Alive!

April 17, 2020

Welcome to Fidalgo Grows, where experienced local gardeners will help your garden be the best it can. We look forward to your comments and questions.  

We’re happy to begin the blog with Fidalgo’s own beloved Peter Heffelfinger, who has gardened in the Fidalgo Island/Skagit Valley area for over 40 years. A Master Gardener, he has taught classes for the Eat Your Yard program, the Know & Grow series at the WSU Extension, the Anacortes Senior College, and Christianson’s Nursery. A former garden writer for Fidalgo Magazine, his column currently appears in the Whatcom Watch newsletter.

 

Introduction to Four Season Vegetable Gardening  

by Peter Heffelfinger

Fidalgo Island has been rated by Seattle Tilth as the best site in the Maritime Northwest for growing vegetables year-round. With low rainfall due to the Olympic rain shadow, and cool temperatures moderated by the Salish Sea, one can plant a wide variety of crops starting in March and continuing on a monthly basis right through October. Early peas and lettuces in the spring; classic tomatoes, corn and beans for summer; hardy greens in the fall; and overwintering brassicas and leeks for harvest during the chill of winter. Not to forget potatoes, onions and winter squash for storage. And finally garlic, the fall-planted bulb that, like the tulips, appears in the spring. 

It is best to think of gardening here not as a one-time rush to get everything in at once, but rather a steady monthly rhythm of “what do I plant today to harvest during the next succeeding season?”  

Since the garden will be in use on a continual basis, it is important to rotate crops to avoid disease, maintain fertility with added organic matter and amendments, and sow winter cover crops to avoid erosion. Endemic pests and diseases come with our moderate climate, but there are strategies and tools to deal with them organically.

Climate change is now an added challenge that is expanding our main growing season at both ends, early and late. With warmer, drier summers and less winter snow-pack, water supply will be the critical issue.

All in all, gardening takes a watchful eye as well as flexibility when things go a bit awry. Given our fortunate locale, there’s always time to replant.
