There are lots of new gardeners now, as a result of the pandemic causing people to stay at home, cook more and want more food security without going inside grocery stores. Maybe last year you bought packets of seeds in a hurry, either online or off a rack in as store. Maybe you hope your garden will go more smoothly this year and I’m here with this blog post to help you.

Or perhaps you are a new professional grower, seeking to improve your game. Or an established one, looking to hang in there by farming smarter in these hard times.

‘Tis the season for garden planning. Inventory your seeds left from last year, peruse the catalogs and prepare your seed orders. The earlier you get them in, the more likely you are to get the varieties you want, before anything is sold out. Be prepared, note your second choice, and fend off disappointment!

I have a course on garden planning for home gardeners, on the Mother Earth Fair Online. It consists of eight half-hour workshops, covering all aspects of garden planning from clarifying your goals, choosing crops, making maps of what will go where, planning when you want to harvest, determining how long your rows will be and how much seed to order, deciding when to plant and scheduling everything to make the year go smoothly. There are also workshops on ways to pack more in, and how to be prepared for things that don’t go according to plan!

Commercial growers and energetic home growers will also be interested in the information on garden planning in my book Sustainable Market Farming.

I have a couple of slideshows on SlideShare.net,

 First, a basic 6 steps of garden planning

  1. See How to Decide Which Crops to Grow.

Think about what you grew last year, and whether you want the same again. Think about what you wished you’d grown. Every year we try to introduce a new crop or two, on a small scale, to see if we can add it to our “portfolio.” Some-times we can successfully grow a crop that is said not to thrive in our climate. (Brussels sprouts really don’t). We like to find the varieties of each crop that do best for our conditions. Later we check how the new varieties do compared with our old varieties. We use heirloom varieties if they do well, hybrids if they are what works best for us. We don’t use treated seeds or GMOs, because of the wide damage we believe they do. For ideas of what you might grow, see our Twin Oaks Harvest Calendar by Crop.

2. Are any of your leftover seeds OK to keep?

See making an inventory, and Ordering seeds! Seed Viability Many seed catalogs include information about seed longevity, and so does Nancy Bubel in The Seed Starters Handbook. Frank Tozer in The Organic Gardeners Handbook has a table including minimum, average, and maximum.

A simplified version of how long to keep seeds is as follows:

  • Year of purchase only: Parsnips, Parsley, Salsify, and the rarer Sea Kale, Scorzonera
  • 2 years: Corn, Beans and Peas of all kinds, Chives, Dandelion, Martynia, Okra, Onions,
  • 3 years: Asparagus, Carrots, Leeks, Rutabagas, Turnips,
  • 4 years: Artichokes, Basil, Cardoons, Chard, Peppers, Pumpkins, Spinach, Squash, and Watermelons,
  • 5 years: Beets, most Brassicas, Celery, Celeriac, Chicory, Cucumbers, Eggplant, Endive, Lettuce, Muskmelons, Tomatoes,

Rather than deteriorating with age, some very fresh seed has a dormancy that needs to be overcome by chilling (lettuce).

The fuller story is that storage conditions make a big difference. Keep seed cool, dark, dry in airtight, mouseproof containers.

  1. How Much of What to Grow?

Make a rough map of your garden space and see what will fit. Remember you can plant a later crop in the same space after an earlier one finishes. See below for more info on quantities of potatoes and garlic, two staples.

  • How Much Garlic to Plant

A yield ratio of 1:6 or 7 seems typical, and makes complete sense when you consider you are planting one clove to get a bulb of 6–7 cloves. Divide the amount you intend to produce by six to figure out how much to plant. For large areas 750–1,000 lbs/ac (842–1,122 kg/ha) are needed for plantings in double rows, 3″–4″ in-row (7.5–10 cm), beds 39″ (1 m) apart. For single rows, 8 lbs (3.6 kg) of hardneck or 4 lbs (1.8 kg) of softneck plants about 100′ (30 m). In the US, one person eats 3–9 lbs (1.4–4.2 kg) per year.

  1. How Much Seed to Order?

Hopefully you kept some kind of record on whether the amount you bought last year was enough. When we figure out how much seed to order we add in some extra for some things – crops that can be difficult to germinate, or we really don’t want to cut too close. We add 20 percent extra for most crops, but only 5 percent for kale, 10 percent for onions and collards and 30 percent for melons. These numbers are based on our experience – yours might be different. We also know which seed we can buy in bulk and use over several years. This gives us an additional security against poor germination, or plagues of grasshoppers or caterpillars. For me, a big bag of broccoli seed for each of our main varieties gives some kind of warm glow of horticultural security! Buying too much either leads to wasting money (if we throw it away) or wasting time and money (if we sow old seed that doesn’t come up well, then have a crop failure).

If you use spreadsheets, see my post Cooking Greens in December Special Topic: Ordering Seeds.

Here’s a helpful table of 1000 Seed Weight for 13 crops. Another of the challenges with seed ordering is converting between grams, ounces and seed counts – have your calculator at the ready, or easier still, just type “Convert ½ oz to grams”into your search engine.

 

  1. Choosing varieties.

See How to read seed catalogs for tips on getting what you really want by paying attention to what’s in the small print and what isn’t mentioned. We carefully look for varieties that offer the flavor, productivity and disease resistance we need. The catalogs are starting to appear in my mail box. The early bird catches the preferred varieties! The main companies we order from are Fedco Seeds, Johnny’s Selected Seeds and of course, Southern Exposure Seed Exchange. We like SESE for regionally adapted varieties, Fedco for great prices on bulk sizes, and Johnny’s for some varieties we really like that aren’t available from the other two.

 

  1. Formatting and placing seed orders

We grow lots of different crops, so we make a spreadsheet, and include columns for the name of the supplier we buy each variety from (we just use the initial), the item number in the catalog, the packet size and the price. (Be careful though, if you carry this information over from year to year – prices change.) Once we have composed our total seed order, we sort the orders by the name of the supplier. Then we can calculate the total price for each supplier. This also gives us the opportunity to look at price breaks for large orders and move an item from one supplier to another, if that makes sense. At this point we usually make a cup of tea and reward ourselves with an “impulse buy” or two, if that doesn’t push us up into a higher shipping cost bracket or blow the budget. We place our orders online these days, nice and early, to increase the chances of getting exactly what we want.

Here are a few more thoughts on crops to consider:

  1. Insurance crops that are there when you need them

For an overall sense of success, grow some “Insurance Crops”. These are reliable vegetable crops that grow without much attention and quietly wait until needed. Chard is one of those. We sow chard in April, after the early spring rush. We plan for it to provide us with leafy greens in the summer, after the brassicas have bolted. We prepare a bed, unroll hay mulch over it, then make “nests” in the hay for planting. Nests are holes in the hay down to soil level, at each spot where we want to plant. After transplanting. we water and tuck the hay tight around the plants to keep the weeds at bay. Some years there isn’t much demand for chard and we just leave it growing. If we need it, there it is with a generous supply of leaves. If we ignore it, nothing goes wrong. It’s worth having some crops like this in the garden, to help ensure there’s always something to eat.

One year we grew Malabar spinach and it played a similar role: hot weather leafy cooking greens. Malabar can be used when small for salads, or when larger for cooking. It wasn’t hugely popular in either role, but it was beautiful. To be fair, I don’t think we did the best by it. Because it was new, and because it had the word “spinach” in its name, some cooks served large leaves for salad. Alone. I don’t recommend that.

Another insurance crop for us is asparagus beans, also known as yard long beans. Once trellised, the plants need no attention, other than regular picking. If not picked, the pods grow puffy and useless, so this is not a crop to ignore for too long. Asparagus beans are related to southern peas (cowpeas), and are more resistant to Mexican bean beetles than regular green beans are. They do need trellising, but once you’ve done that, the same plants will feed you all season. Very little seems to trouble them.

While we’re on the topic of crops that do need trellising, but can then produce all season, I’ll add in the West Indian gherkins. I found I did need to tuck these plants into the netting, so they weren’t work free. But the plants were disease-free and very productive. If you have trouble with regular pickling cucumbers, you might sow some of these as well, to be sure of being able to have something to pickle.

Another insurance crop is Tokyo bekana, or its cousin Maruba Santoh in late summer as a substitute for lettuce. It can be hard to germinate lettuce in hot weather, but these tender brassicas germinate under hot conditions and produce fast-growing very tender leaves with crunchy stems. Some people don’t know they’re not eating lettuce!

Senposai is a cooking green that does well in spring and fall outdoors, and in our hoophouse in the winter. It’s fast-growing, productive, disease-resistant, easy to cook and delicious to eat.  In spring it needs an early start in our climate, so that it has time to be productive before it bolts. In fall it’s cold-hardy down to 12F.  Its Achilles Heel is that it can really attract Harlequin bugs! We did spend time every day for a while squashing the bugs on the senposai leaves, and we made a difference in the number of bugs.

Well, I hope this has given you some thoughts about ordering seeds of some insurance crops for next year, when you plan your seed order.

  1. VEGETABLE CROPS THAT OFFER FAST RETURNS

Because things can go wrong in agriculture, (we are, after all, not in control of the universe!) I like to have on hand seeds for fast-growing crops that can fill unexpected gaps.

  1. Eat-All Greens

Carol Deppe, in her delightful book The Tao of Vegetable Gardening introduces us to the concept of Eat-All Greens. Carol grows these by broadcasting seed of one of her carefully chosen greens crops in a small patch. When it reaches 12″ tall, she cuts the top 9″ off for cooking, leaving the tough-stemmed lower part, perhaps for a second cut, or to return to the soil. I wanted to try this idea in Virginia, where the climate is fairly different from the Pacific Northwest where Carol lives. I decided fall was a promising time of year to try this scheme, as our spring planted greens only have a short season before they bolt. And summer is too hot, winter too cold. . . We sowed in mid-September.

These can also be insurance crops, in that, if you don’t need them, you can cut and compost them, to let fresh leaves grow. I wrote three posts on Eat-All Greens, because they were such fun and so productive

    1. Hi Raina,
      We grow buckwheat as a cover crop, but I hear that on a small scale, it’s possible to tickle mature plants and collect ripe seed into your hand. Of course, if you do this, you risk ripe seed landing on the soil and sprouting. If you are close to planting your next crop, you don’t want buckwheat seedlings coming up and smothering your intended crop. Pam
