Growing Squash and Zucchini
Summer squash and zucchini are famous for producing more food than seems reasonable from one plant.
The main challenge in Alabama isn’t usually getting them to grow. It’s keeping pests from ending the party early.
When to Plant
In Central Alabama, summer squash is commonly planted in April, with another planting window around August 1–15.
Plant after frost danger has passed and the soil has warmed.
Seeds or Transplants?
Direct sowing works very well.
If you use transplants, set them out while still young and avoid disturbing the roots.
Sun and Soil
Squash prefers:
- Full sun
- Rich soil
- Good drainage
- Plenty of space
Add compost before planting.
Spacing
Do not crowd squash.
Leaves grow quickly and need airflow.
Allow enough room for the mature plant rather than judging spacing by the tiny seedling.
Watering
Water deeply at the base of the plant.
Avoid repeatedly wetting foliage when possible.
Mulch helps preserve moisture and reduces soil splash.
Pollination
Squash produces separate male and female flowers.
Male flowers usually appear first.
Female flowers have a tiny squash-shaped ovary behind the blossom.
Bees move pollen between the flowers.
Poor pollination can cause tiny fruit to yellow and drop.
Squash Vine Borers
These are among the most frustrating squash pests.
Signs include:
- Sudden wilting
- Frass near the stem base
- Damaged stems
Check plants often because early detection matters.
Squash Bugs
Look for:
- Bronze egg clusters
- Gray nymphs
- Adults hiding near stems
Removing egg masses early can make management easier.
Powdery Mildew
White powdery patches on leaves are common later in the season.
Good spacing, airflow, resistant varieties, and proper watering can help.
Harvest
Pick zucchini and yellow squash while still tender.
Overgrown fruit becomes tougher and seedier.
Harvesting regularly also encourages continued production.
GardenGrowz Tip
Plant fewer squash plants than you think you need—and consider a second planting later instead of trying to keep one planting alive forever.
