How to Grow Summer Squash in a Container Successfully

Growing summer squash in a container works well when you give the plant what it needs from the start.
 
Here’s how to grow summer squash in a container the right way:
 

1. Choose the Right Container Size

To grow summer squash in a container, you need a pot that holds at least 5 gallons of soil.
 
A 12-inch deep container with a 12- to 14-inch diameter is the minimum for most summer squash varieties.
 
If you want to grow summer squash in a container without the plant getting root-bound, go bigger.
 
A 7- to 10-gallon pot gives your squash plenty of room to spread its roots and stay healthy.
 
Make sure your container has drainage holes, because squash roots hate sitting in soggy soil.
 

2. Pick a Bush Variety for Containers

Not all summer squash varieties grow well in pots, so choose a bush type instead of a vining one.
 
When you grow summer squash in a container, bush varieties stay compact and produce heavily.
 
Good choices include ‘Black Beauty’ zucchini, ‘Patio Star’, and ‘Eight Ball’.
 
Yellow straightneck and crookneck bush types also grow summer squash in a container beautifully.
 
Avoid sprawling vining types, as they’ll quickly take over your patio.
 

3. Use Rich, Well-Draining Potting Mix

The best way to grow summer squash in a container is to start with quality potting mix, not garden soil.
 
Garden soil compacts in pots and drains poorly, which can rot your squash roots.
 
Instead, use a potting mix blended with compost and a slow-release organic fertilizer.

Place your pot where it gets morning sun and some afternoon shade in very hot climates.
 
If you grow summer squash in a container in too much shade, you’ll get leaves but few fruits.
 
Rotate the pot occasionally so all sides of the plant get even light.
 

4. Watch for Pests and Pollination

Growing summer squash in a container doesn’t protect it from squash bugs or vine borers.
 
Check under leaves regularly for eggs and handpick pests when you spot them.
 
Since bees may visit your patio less often, you may need to hand-pollinate summer squash flowers.
 
Use a small brush to move pollen from male to female blossoms for better fruit set.

Leaving squash on the plant too long slows production and makes the flesh tough and seedy.
 
Use a sharp knife or pruners to cut the stem cleanly instead of twisting the fruit off.
