Seeds to Start in June

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.
