Demystifying Seed Catalogs

Get seed catalog savvy

Lisa Hilgenberg —  February 16, 2017 — 6 Comments

The arrival of seed catalogs in mailboxes ranks as one of the most hopeful times in a gardener’s year, as it provides us with a welcome link to spring.

February is the perfect time to plan next spring’s vegetable garden. One of the first considerations is deciding what to grow. This can be answered by simply listing the veggies or asking your family to name the veggies they like to eat. There are a few other considerations before placing your order for next year’s garden—such as deciding if you should plant seeds or transplant vegetable starts. Seeds of many vegetables can be sown directly in the garden, including root vegetables like carrots, radish, and beets. Peas, beans, and squash are also best directly sown. Cabbage, tomatoes, and peppers are better given a head start inside first, and then transplanted into the garden as small plants, because they need a long, warm growing season.

For spring plantings, set broccoli transplants out two to three weeks before the last spring frost date.

Timing is important in the vegetable garden, and knowing that our growing season has approximately 170 frost-free days helps guide decisions on which plants to plant and when to plant. Our risk of frost is generally from October 15 through April 27, but can vary two weeks in either direction. Understanding that vegetable varieties have varying tolerances to frost helps you plan your planting calendar. For example, those very hardy plants like collards, kohlrabi, kale, spring onions, pea, spinach, turnip, and cabbage can be planted out four to six weeks before our last frost date. Those called “half hardy” or “frost tolerant”—such as beets, Swiss chard, carrots, cauliflower, and mustard—must be planted a bit later; two to three weeks before the last frost date.

The best seed catalogs will help decipher a gardener’s questions, and help plot, measure, and sort out the seed math needed to get started on a vegetable garden. Most seed is available in organic and non-organic options, with the latter usually the least expensive. Good catalogs provide keys to help decipher the icons (vegetable resistance codes) in plant descriptions. After all, a seed company’s success is based on a gardener’s success with their products.

As our nutritional consciousness rises, the taste and the health benefits of growing your own organic produce is a pursuit worthy of winter afternoons spent planning.  

Here are a few of my favorite seed companies:

The fittingly named Rare Seed Catalog is like the Vogue magazine of the vegetable world. It wins the prize for the most beautiful photographs of the most avant-garde produce collection, complete with nutritional factoids and culinary inspiration. Stories from seed collecting expeditions around the world—recently Thailand, Myanmar, and India—are in the Heirloom Gardener, an associated and nationally distributed magazine written as a tool to not only promote and preserve our rich agricultural history but as explanation of why we need to care about it. The Rare Seed Catalog provides a selection of 78 varieties of melon and 20 types of okra. Baker Creek has a limited but diverse availability of live plants to ship. If goji berries, ginger root, and dragon fruit tickle your fancy (and you either live in the subtropics or have a greenhouse available) look no further, they’re in the Rare Seed Catalog. Baker Creek encourages political activism, and the catalog is written with an underlying ripple that we’re reaching the tipping point in the struggle against GMOs.

Varieties/cultivars and tips for direct seeding into spring gardens

It’s hard to resist a list of a few of my favorite varieties to directly sow into the spring garden. Knowing how much seed will sow a 10-foot row and the days to maturity (when the harvest can be expected) is the type of garden math that tangles up many a gardener, but quality catalogs will provide vegetable grower’s guides to help to sort out how much seed you’ll need. 

Radish: Direct-sow spring radish as soon as the ground can be worked, or four to six weeks before the last frost. Radish is best grown quickly in cool, damp conditions. It’s easy to grow, and requires only 28 days from planting to harvest. Try these spring radish cultivars: ‘Early Scarlet Globe’, ‘Rudolf’, and ‘Crunchy Royale’.

PHOTO: Beets.Beets: Nothing says spring like tender, freshly harvested baby beets. Sow about two weeks before our last frost date and thin to 3 inches between seedlings. Fertilize with liquid seaweed. Beets have great culinary versatility, so plant a combination of gold and red. ‘Detroit Dark Red’, ‘Bull’s Blood’, and ‘Burpee’s Golden’ are great choices.

Swiss chard: We love ‘Rhubarb’ and ‘Five colored Silverbeet’. These greens can grow through the entire gardening season. By harvesting just the outer leaves with a harvest knife, the plant stays in place and the integrity of your design stays intact.

PHOTO: Carrots.Carrots: The sweetest, juiciest, and most flavorful carrots are the French heirlooms. Sow two weeks before the last frost date. Carrot is slow to germinate, so have patience. Our favorite varieties for Chicago growers: ‘St. Valery’, ‘Paris Market’, and ‘Scarlet Nantes’.

Spinach: One of the earliest-germinating cool season vegetables, spinach can be direct sown in 2-inch bands or rows four to six weeks before the last frost. Plant ‘Corvair’, ‘Tyee’, or ‘Donkey’ for the most reliable spring crops.

Lettuce: We love ‘Tennis Ball’, ‘Black Seeded Simpson’, ‘Rouge d ’Hiver’, and ‘Winter Density’. One gram of seed will sow a 15-foot row.

Spring greens: Try mache, arugula, or mizuna; 30 to 50 seeds will seed one foot of row when sown as a cut-and-come-again salad mix.
