Most people wait until Victoria Day to put their garden in, but there are many vegetables that can be planted before the end of May. If you prepare your garden in the fall, you will be able to spread the work of planting over several weeks instead of doing it all in one weekend. You will harvest sooner and feel like there is less work to do.
In mid-April to early May, there are many frost tolerant plants that can be seeded into the garden, such as broccoli, beets, cabbage, Swiss chard, leaf lettuce, onions, peas, radishes, rutabaga, asparagus, garlic, kale, kohlrabi, leeks, turnips, parsnips and spinach.
In early to mid-May, plant carrots, cauliflower, head lettuce, celery, corn and potatoes.
The only plants that cannot be seeded until after the last frost date are beans (try planting some early, some on the last frost date, and some later for beans all summer), cucumbers, squash, and zucchini. Eggplant, tomatoes, melons, peppers, and pumpkins should be started early indoors or purchased as transplants, and set out at this date.
If your ground stays frozen all winter, try a fall planting of carrots, lettuce, onions, parsnips, spinach, and Swiss chard. At least some of the seeds will probably survive, and you will get a much earlier crop than usual. Fall is also the best time to plant garlic. So don't wait until spring is here - invite it with an early harvest!
