Vegetable Planting Calendar

The third vegetable planting season is here - mid-July.  There is plenty of time to seed many different crops that will mature in about sixty days. This is based on a mid-October hard freeze.

Scroll over to the right to view the Fall Planting column.  You may have to tuck in the seeds here and there, wherever you have room for them to grow.  Keep in mind that later in August, even early September you can seed lettuce, spinach, arugula and radishes, the quicker maturing cool-season crops. 

Cool-season vegetables and herbs that can be seeded right now include beets, Brussels sprouts, cabbage, cauliflower, cilantro, Swiss chard, celery, collards, bunching onions, parsley, peas.

Warm-season vegetables and herbs that can be seeded right now include basil, bush beans, slicing cucumber, okra, New Zealand spinach, summer squash.
