What To Do This Spring While PPCG Is Closed

Complete a free vegetable gardening module from Oregon State University’s Master Gardener program. Some of the information in this program may be best suited for Oregon’s growing climate, but most looks like it’s relevant to us.

Follow the Insect Xaminer, a short video series from UMass Extension starting with (drum roll) the Gypsy Moth caterpillar. This first installment is quirky-gruesome in the context of  the pandemic, but I’m sticking with the series for its promised information on common insect pests.

Try a modified version of a technique known as winter sowing. I’m not encouraging anyone to run out to the store to buy anything, but if you can get your hands on a milk jug (or similar container functioning as a mini greenhouse), a small bag of seed-starting mix, and some lettuce seeds, cilantro, or spring onions, you can grow outside in a small, sunny space.

  • Because these plants like cold, you’ll have to open your containers on warm days or they’ll cook.
  • Once they are established with a few sets of leaves, you can probably leave the top off for good, unless we have an overnight with temps down into the 20s F.
  • I’ve never tried it, but some gardeners even start up their warm weather plants  (around now) in this fashion, though again, you’ll have to keep an eye on the weather. If we get a cold snap, throw a blanket over them.
  • There are a few benefits to protected outdoor sowing of garden plants. They’ll receive more light outdoors. (Even a sunny windowsill might not be bright enough for your plants, even if it looks bright to you.) Plus you won’t need to harden them off if you transfer them to a larger growing space. Just be aware that I don’t know when we’ll be able to get back in the gardens.

Holly Hill Farm–which like many other businesses is in need of our support–appears to still be having its early plant sale on April 18 & 19. (Their warm-weather plant sale usually happens in May.) Keep an eye on their website and/or sign up for email updates. They have altered their sales methods in response to COVID-19 concerns.

Stay tuned for more details from Braintree Farmers Market. They went to a virtual model on April 4, and it looks like the next date is May 2.

Five Indoor Seed-Starting Tips from Margaret Roach’s A Way to Garden

Select Seeds Suited for Indoor Sowing and Transplanting

Many crops start well indoors–and need the extra growing time in a protected space while the weather is still too cold–but a few grow better when sown directly in the garden. There aren’t any no-break rules here. Even carrots can be transplanted, though it’s not generally recommended. Especially if you are trying a crop for the first time, read the seed packet for instructions on which method typically works best. Pay attention, too, to the days to maturity information and your crop’s cold tolerance to help decide where and when to sow.

Start with Good Materials

DSC_1656
Many seeds are viable for more than one year, but members of the onion family are notoriously short-lived. Pictured here, I sowed the far corner with fresh onion seeds and the near corner with seeds only 1 year-old. Barely any of the old seeds germinated.
  • Clean your seed-starting containers with a 1:9 bleach:water solution or soapy water.
  • Use a sterile grow medium formulated for seed-starting.
  • For best results, use fresh seeds. (See this link to a chart on seed viability and a great discussion on the difference between viability and vigor. More info here.)

Water Wisely

Keep your planting medium evenly moist until your seeds sprout, then let it dry out slightly between watering. In no instance should it be soggy or bone dry. Be gentle if you water on top and use a mister or similar method. Bottom watering avoids the problem of dislodging seeds and young transplants and helps prevent diseases.

Get the Light Right

This one is Margaret Roach’s most emphasized tip. Seedlings will need supplemental lighting–more than they’ll likely get on your windowsill–or they’ll grow tall and spindly.

For Perkins Park Gardeners: What to do if you don’t have a fancy grow light set up and still want to sow your own seeds for transplanting?

    • Try inexpensive shop lights. I’ve had reasonable success growing seedlings with a couple of shop lights purchased for around $15 at Ocean State.
    • Squeeze one or two cell packs on your windowsill and supplement with a simple clamp light fixture (bulb separate). Set them outside on warm-enough days, taking care to harden them off (see next tip) along the way.
      DSC_1682
      Lettuce seedlings grown on a windowsill get a little long and floppy, but do all right if you don’t have to hold them long indoors.
      DSC_1685
      But seedlings quickly dry out and outgrow their small egg carton confines.

      DSC_1686
      Here’s another windowsill setup, fashioned out of a recycled cell pack and a milk carton, that gives seedling roots more room to grow.

Take Time to Transplant with Care

Harden off plants before you transplant them to their final space in the garden. They’ll need to gradually acclimate to outdoor conditions, especially to the sun. Start with no more than 1 hour outside in direct sun on the first day (not midday) and gradually increase the time of outdoor exposure over the course of about a week. You’ll know you’ve overdone it if you see bleached or brown and crispy patches on your plants’ leaves. Alternatively, some people like to choose overcast days, leaving them outside during daytime hours for a few days.

Once you’ve gotten your plants hardened off, make sure you’re not rushing to get your plant in the garden too early, before you are reasonably clear of of unsuitable weather.

Spring Crops

What are the first crops that we should consider planting in our gardens in the spring? When the soil can be worked, we have a wide range of cold-hardy choices to consider. These crops all have a few things in common. They:

  • germinate in cold soil
  • grow well under cool conditions, and
  • tolerate a light frost.

Many of these crops can and should be planted in cool conditions, else you risk poor germination, poor development, and inferior flavor and/or texture. You’ll want to get them in the ground as early as you can to allow them time to develop before the heat of summer sets in. With good planning and a little cooperation from the weather, you’ll be able to harvest these crops in time to follow up with a warm weather crops such as beans, tomatoes, and cucumbers. Pay attention to the days to maturity information listed on many seed packets, and look for quick-growing varieties to make the most of your growing season. Also, be prepared to cover your crops with frost protection if temperatures take an abrupt and extreme downturn. Or stagger your plantings with the anticipation of a few losses.

  • arugula
  • beets*
  • broccoli
  • Brussels sprouts
  • cabbage, including Chinese cabbage
  • carrots*
  • cauliflower
  • celery

  • lettuce
  • onions*

Cilantro (foreground) often reseeds itself and grows in the spring when conditions are just right. If you like it, leave it be. Self-sown plants are often the least fussy.
img_20191210_082746432
Lettuce, spinach, tatsoi, and Hon Tsai Tai, a broccoli-like green, thrive under cool conditions. Damage thanks to slugs.

In my home garden, I’ve been able to overwinter a few of these crops–lettuce, arugula, bunching onions, spinach, tatsoi, carrots, parsley, cilantro, kale, and Hon Tsai Tai, a broccoli-like green–under protection. They didn’t grow much, but under protection, the limitation seemed to be more about diminishing winter light than cold.

On the other side of spring, a few of these crops such as the ones marked* generally can carry over well into hot conditions. With regard to one of these crops–carrots–I think a better option is to select quick-growing cultivars that mature in late spring/early summer, and then squeeze in another crop of in the fall, perhaps for overwintering. They’ll taste sweeter if they are harvested in cool conditions.

Some of the others on the cool list, such as lettuce, have cultivars purported to withstand the heat. I have yet to find a lettuce I can grow well in the summer heat, no matter what the claim on the seed packet. (Anyone? I’d love to have some lettuce with my summer cucumbers and tomatoes.) BUT, you can cheat the season a little by growing leafy vegetables in partially shaded areas.

One other note: Last summer my parsley bolted (went to seed) in early summer, and I have since read that young parsley seedlings exposed to substantial cold are more likely to have this tendency. In this case, you may want to grow a backup batch for late summer/fall. If the winter is not too harsh, they’ll even overwinter.

Ready to do some cool growing? Happy spring, everyone!

Use this planting schedule as a very rough guide.

Here’s a more tailored seed-starting and setting-out calculator from Johnny’s. (Note that you have to enter our region’s frost-free date, which can be tricky to figure out. The Farmer’s Almanac reports a frost-free date of April 22, using weather data from South Weymouth and allowing for a 30% risk of frost.) I feel all right using this data for cold-weather plants, but for warm-weather plants, I like less risk of frost.

Spring In the Wings

Overall, this winter hasn’t been a bad one here on the South Shore–right?–but it seems to be going out with hooks.

So I’ve put together a list of a few garden-related doings to get us to the end. After all, opening day at PPCG is only a little more than a month away, and then we’ll be within easy reach of peas.

Boston’s Community Garden Scene

Next week on Wednesday, February 27, the Trustees, which owns and operates the largest chunk of community gardens in Boston, is showcasing a documentary film about Boston’s community gardens at More Than Words bookstore. Pre-registration recommended. Reduced rates for members.

Gardening Aside

By the way, More Than Words is one of my favorite indoor spaces, a used bookstore run as a nonprofit, so if you’re just looking for a nice place to get out of the cold, go check it out. I don’t know their schedule this year, but in the past they’ve held big sales on/around March 17. (And while I’m on the topic of used bookstores, have you been to the Montague Bookmill in western Massachusetts? It’s a great road trip destination with a few good hiking spots nearby.)

Countertop of Greens

Grow a crop of microgreens before you need your sunny/lamp-lit spaces for seedlings. Here’s my favorite how-to video. Or sign up for Holly Hill Farm’s workshop on growing microgreens on March 9 from 1 – 3. Or buy a bunch of greens and shoots at their weekly farm stand. See their website for details; locations vary.DSC_1648

Library Harvest

Have you used Hoopla, a free source of electronic media that’s available at our public library? Hoopla currently has a surprising number of gardening books, such as Countertop Gardens, Indoor Kitchen Gardening, High Yield Vegetable Gardening, and Thrifty Gardening. Or how about Dogscaping, How Carrots Won the Trojan War, or A Woman’s Guide to Cannabis?

Braintree’s Hidden Garden Source

Go check out all of the living things growing indoors under lights at Gardin, which outgrew its location at New England Wildlife Center and moved to its current warehouse space at 137 Bay State Drive, near the Braintree high school.  This place makes you want to turn your whole house into a terrarium. They have a huge array of indoor and outdoor growing supplies, some of which are hard to find elsewhere in our area, plus friendly, informed service. Matt helped me pick out a grow light for starting some microgreens and herbs on my countertop.

Plus, they have a turtle. This guy has the best turtle home ever.

Hang in there, everyone.

 

 

 

Deer Vs. Gardeners II

I used to say that while we had a few deer visitors every year at PPCG, the humans always took home more from their gardens than the deer did.

And then last year happened.

Going into our 2019 growing season, I’m going to assume that if we want more harvest than heartbreak, we’re going to need to start off with active defenses. The good news is that many of us found some reasonable solutions that worked well for us.

For more info about deer control, see this post. Here I’m going to focus on the methods that seemed to work well for our gardeners, along with a few sources and best prices. (If you find some better options, please share!)

Repellent: Plantskydd

At least one of our gardeners, Gary  (plot 31), had good luck with this product, which is sprayed on plants. OMRI-listed, it’s main ingredient is dried animal blood. For the best results, you’ll want to spray it early in the season, before deer get a taste of what’s in your garden. 

Pros:  One of the least expensive options in terms of initial outlay. No need to struggle with fence installation. Allows you to keep your garden open and easily accessed. Doesn’t wash off in rain. Organic.

Cons: Needs to be applied to new growth, so you do have to keep up with it. Since its main ingredient is animal blood, it (1) may not be an option for vegetarian gardeners and (2) will add nitrogen to your soil, which you may or may not want. Also, although the product specifies it’s safe for garden vegetable plants, you can’t spray it on any part of the plant that you intend to eat, such as lettuce leaves or tomatoes. There’s also a granular formula that you can sprinkle around your plants.

Available at: Amazon for $23.99 for a 32-oz. spray bottle or at Park Seed for $21.95. Check here for local dealer locations. You can also buy larger quantities in powder concentrate that you have to mix and a granular formula for sprinkling.

Fence Option 1: Multi-Purpose Netting

IMG_20180503_103531591.jpgJun (plot 24) and I (plot 30, photo right) used this product by Tenax with good success. At 4-feet tall, it’s an easy jump for deer,  but I’ve read that deer don’t normally like to jump into enclosed spaces as small as our gardens. For extra measure, I put a few obvious tomato cages inside my plot to clutter up the landing zone.

This product is sturdier than the netting described below, but not really sturdy enough to support  vines such as cucumbers. I installed it using 60-inch u-posts, slipping the fence onto the hooks on the posts as I wrapped it around the garden. 

Pros: Sturdy. Should last a few years. Relatively easy to install; I was able to do it myself. Most difficult part for me was pounding in the u-posts. Allows easy access to gardens–just unhook the netting from the posts. (The whole garden can be opened quickly and easily.) Even though it’s thicker than the deer netting below, it’s still unobtrusive and doesn’t cast significant shade. Can also be purchased in 7′ x 100′ rolls, enough to keep out jumpers from two garden plots. 

Cons: Costs about $24 for the netting plus $27 – $45 for 6 – 10 u- or t-posts. Not a good choice for folks who don’t want to go to the trouble of installation or who don’t like enclosed garden spaces. Not tall enough to prevent jumpers or “leaner-overs.” The 7′-tall fencing will need sturdy, more expensive posts to be installed properly.

Available at: Lowes in Weymouth and on Amazon.

Fence Option 2: Deer/ Wildlife Netting

Product Image 2A few gardeners used a product like this one, which is finer and less stiff than the multi-purpose netting above. They installed it using bamboo or green plastic garden posts, attaching the fence to them with twine, zip ties, or tomato Velcro. I’ve also seen recommendations to hook the netting onto nails, screws, or cup hooks fastened to wooden garden stakes, which then could function a lot like the netting above.

Pros: Tall enough to keep the champion jumpers out. Reusable. Lightweight and unobtrusive. No problems with product casting shade. Depending on how it’s installed, it can be removed easily if you need better access to your garden for maintenance, etc.. The cost of the netting itself is reasonable, around $20.

Cons: Must be secured properly. Potential tripping hazard. Does a number on our lawnmower. Ideally, should be marked with flagging tape so deer see it and don’t blunder into it. Could be chewed or torn. A little fiddly to use. Best installed with a second set of hands. To make full advantage of the height, you need tall support posts, which may cost more than the netting itself.

Barrier Cover: Bird Netting

Bird netting is similar in weight to the wildlife netting above, but sold in dimensions that allow you to drape it over large sections. This option is a good, inexpensive one if you want to protect certain plants or sections of your garden. 

 

This slideshow requires JavaScript.

Pros: Perhaps the least expensive option. Allows you to section off areas of your garden, leaving open access to other areas. 

Cons: Like the wildlife netting, it’s fiddly to use. Must be secured properly! (I used clothes pins, attaching the netting to twine stretched between stakes.) Potential tripping hazard. Gets tangled in our lawnmower. Depending on how it’s installed, can make garden access annoying. Your plants won’t like bumping up against it, so your netting supports have to be taller than your plants at full height.

 

Available at: Lowes in Weymouth and Home Depot in Quincy. (See photos below.)

Final Thoughts…

Repellents, fencing, or cover netting…there’s no perfect solution here, but we managed to find a few workable options that allowed us to recover last summer. Pick the one that works best for you and go for it–early in the season. It’s better to set up your repellents and barriers as soon as possible, before deer get a taste of the good stuff  in your garden.

Happy gardening, everyone!
