plant the rest of the seeds in the pack in the local HOA president's rose garden.
squash, peppers, and cucumbers are the most space efficient
If I can find my seeds, I was going to three-sisters some planters with mini pumpkins (for feeding dogs), edamame and sweet corn.
Carrots and leeks in planter bags, and lettuces with a grow light in the cellar.
I had good luck (when I had the spoons for gardening) with the marinara planter, especially with marigolds nearby for pest protection.
