Pre-Seed Vegetable Seeds

To seed in advance for fall, winter, and spring.

Advancing seeds for fall, winter, and spring gardens means starting or preparing seeds early—either by sowing, pre-seeding, or transplanting—so that you maximize your growing time, especially in climates with short seasons like much of Canada.

Here’s a breakdown of which seeds you can advance (start early or pre-seed) for Fall, Winter, and Spring harvests and how to do it:

Fall Garden (Plant in Summer for Fall Harvest)

Start seeds in July–August, either directly in the garden or indoors for transplanting.

✅ Great seeds to advance:

  • Leafy Greens: Kale, spinach, Swiss chard, mustard greens, arugula
  • Root Vegetables: Carrots, beets, radishes, turnips
  • Brassicas: Broccoli, cabbage, cauliflower, Brussels sprouts

🧑‍🌾 Tips:

  • Pre-seed indoors or under shade during hot summer.
  • Harden off seedlings before transplanting in cooler fall soil.
  • Use row covers or cold frames to extend the season into late fall.

Creating a Winter Garden from seed involves selecting hardy, cold-tolerant crops that can either be sown in late summer/early fall for winter harvest or overwintered for early spring harvest. Here's a list of seed varieties ideal for a winter garden, especially in Canadian and northern U.S. zones:

🌱 Winter Garden Seed Varieties

🥬 Leafy Greens

  • Kale (‘Winterbor’, ‘Red Russian’) – Extremely cold-hardy.
  • Spinach (‘Bloomsdale Long Standing’, ‘Giant Winter’) – Sweetens with frost.
  • Swiss Chard – Survives mild winters with mulch.
  • Mâche (Corn Salad) – Very cold-tolerant; perfect for salad greens.
  • Claytonia (Miner’s Lettuce) – Thrives in cool, damp conditions.

🥕 Root Vegetables

  • Carrots (‘Napoli’, ‘Merida’) – Can be overwintered in the ground with mulch.
  • Beets – Early fall sowing gives sweet winter roots.
  • Turnips – Fast-growing and frost-tolerant.
  • Parsnips – Require frost to develop flavor; sow midsummer.
  • Rutabaga – Cold-hardy and stores well.

🥦 Brassicas

  • Cabbage (‘January King’, ‘Wintergreen’) – Overwinters with protection.
  • Broccoli (‘Purple Sprouting’, ‘Calabrese’) – Best for overwintering in mild climates.
  • Brussels Sprouts – Improves with frost.

🌿 Herbs

  • Parsley – Cold-hardy biennial.
  • Chives – Hardy perennial, regrows early in spring.
  • Thyme, Oregano, and Sage – Hardy perennials in many zones.

🧤 Tips for Winter Gardening Success

  • Use Cold Frames or Row Covers to extend harvest and protect seedlings.
  • Mulch heavily to insulate soil and root crops.
  • Choose short-day or overwintering varieties specifically labeled for cold climates.
  • Succession plant in late summer (August–September) for a steady supply through winter.

🌱 Spring Garden (Start in Late Winter or Very Early Spring)

Advance seeds indoors in February–March to transplant after the last frost.

✅ Ideal for seed advancement:

  • Tomatoes, peppers, eggplant (start 6–8 weeks before last frost)
  • Brassicas (broccoli, cabbage, cauliflower)
  • Herbs: Parsley, dill, thyme
  • Lettuce, onions, leeks (early starters)
  • Peas: Soak and pre-sprout for fast germination

💡 Tips:

  • Use grow lights or sunny windowsills.
  • Harden off plants before transplanting outdoors.
  • Use cold frames to get an early start in the ground.

Waltham 29 Broccoli, North American Favorite, Broccoli Seeds

Broccoli Waltham 29 is prized for its large 4-6" dark blue-green heads and marvelous flavor. It has a reputation as a superfood because it contains a wealth of nutrients and antioxidants that support many aspects of human health. 

Broccoli seeds can be started indoors.

Start seeds inside 8 weeks before the last frost date. Place seeds 1/2" deep in pots with growing mix and place in bright light. After 5 weeks transplant the seedlings 2' apart into enriched garden soil with full sun. Broccoli is a cool-season vegetable that likes daytime temperatures in the 60s and can tolerate light frost and temperatures down to the 20s. 

Seeds take 3-4 months from the time of planting to a broccoli harvest while transplants only take 2-3 months. Unless you start seeds indoors over the winter, it may be difficult to grow a spring broccoli crop from seed, because the weather will warm too quickly. Fall crops are much easier to start from seed directly in the garden. For fall planting, build rows 2' apart and plant broccoli seeds 1" deep and 6" apart. When seedlings are 6" tall thin them to 2' apart.

Broccoli grows quickly and it needs a lot of nutrients. Rich compost will help feed your plants, and they can also benefit from applications of compost tea or from monthly applications of a balanced organic fertilizer. Like other veggies, broccoli needs to be kept evenly moist and water deeply to encourage deep roots. Mulching can help to provide uniform moisture, conserve water, and reduce weeds.  

Each packet contains 50 Broccoli Waltham seeds. Brassica oleracea. Annual. Open-pollinated, heirloom, non-GMO. Harvest in 85 days.

Australian Yellow Leaf lettuce is a tender, mild-flavored leafy lettuce best known for its soft texture and gentle sweetness. While it’s most commonly used fresh, it also works well in light cooking where minimal heat is applied. The leaves can be quickly wilted into stir-fries, added at the end of soups, or gently sautéed with garlic and olive oil as a delicate side dish. Its tender structure makes it ideal for lettuce wraps, braised dishes, or lightly steamed preparations where it absorbs flavors without becoming bitter, adding a subtle, buttery note to warm dishes.
