Now we’re just three weeks away from the longest day of the year (summer solstice on June 21st), so the soil is warm enough to plant squash and bean seeds. Even in colder climates where the nights are still frosty, the growing season is just around the corner.
Maybe you have already planted carrots and lettuce, and your spring planted vegetable garden is already producing. Remember that planting more seeds now will produce a vastly extended harvest period. Planting more flower seeds now will extend your garden’s bloom time.
And now is the time to seriously consider planting seeds for fall and winter harvest. This is our list of seeds to start in June.
Direct sow outdoors:
Celeriac (for winter harvest)
Endive & Radicchio (for fall & winter harvest)
Leeks (for winter harvest)
Rutabaga (wait until after June 21st)
Seeds to sow indoors in June
Brussels Sprouts (transplant in early August, fall & winter harvest)
Cauliflower (transplant in August for fall harvest)
Overwintering Onions (sow in late June, transplant in August)
Purple Sprouting Broccoli (transplant in August for winter & spring harvest)
