Overview

Zucchini, pattypan and yellow crookneck are just a few of the choices when it comes to summer squash. These plants all produce an abundant crop from midsummer through fall. Summer squash grows well in pots if you do not have the space for a traditional garden bed. The sprawling squash vines require support in a container so the plants take up less room. A benefit to this is the squash is easier to access and harvest. Potted summer squash care is similar to that of garden squash.

Step 1

Fill a 14- to 18-inch diameter pot with a well-draining potting mixture. Use a pot with bottom drainage holes that is 16 to 18 inches deep.

Step 2

Sow the summer squash seeds to a depth twice that their width, or approximately 1 inch deep. Plant two seeds per pot.

Step 3

Water the soil in the pot until the excess moisture drains from the bottom. Water the pot when the top 1/2 inch of soil begins to feel dry.

Step 4

Insert an espalier-style trellis into the pot near the rim, pushing the trellis into the pot until it touches the bottom. An espalier is a small lattice trellis that is narrow at the bottom and wide at the top.

Step 5

Thin each pot to one plant once the seedlings grow in their second set of leaves. Pluck out the smaller, weaker seedling leaving the stronger one to grow on.

Step 6

Tie the summer squash vine loosely to the trellis once the vine is 8 inches long. Use a cloth or plastic plant tie to secure the vine. Continue to tie the main vine of the squash to the trellis every 4 to 6 inches as it grows.

Step 7

Fertilize the summer squash every two weeks with a soluble plant food formulated for vegetables. Follow the label application rates.
