Its not too late to plant!

Broadcasting seeds is easier and more productive than planting rows for parsley, lettuce and herbs. I like to plant green onion seeds in rows, because they look so much like grass, it's hard to weed unless they're in rows. My coworker, Val the Volunteer has a planter on her porch that she planted basil in. It's close enough to the kitchen that she can dash out to snip off some leaves to use with dinner. I  have done this with lettuce in years past. Cherry tomatoes are nice to have in a planter on your patio too, to add to dinner.
Michiganders can still put plants out and plant seeds for lettuce, Swiss chard and other greens, beans and squash. Summers are long enough for two plantings of beans.

To plant a straight row, use a hoe to slide down the length of desired row or use a long string, tied to 2 sticks placed at each end. Then use that same string for every row,  putting sticks at each end of every row. For planting beans, push each seed down in the ground with a finger, 3 inches apart down the row. Then go back and cover with dirt. Be sure to make a garden map, writing down what you planted in what rows. I know it takes the mystery out of gardening, but its more rewarding that way.
