Growing Tips for Squash
- Plant only after soil is fully warm (65°F+) — cold soil rots seeds and creates disease-prone seedlings.
- Squash vine borer kills plants from the inside in July–August in the eastern US; plant a backup crop in early July.
- Hand-pollinate using a small brush if fruit falls off small — squash need bee visits for fruit set.
- Harvest at 6–8 inches for summer squash; letting squash grow large signals the plant to stop producing.
Companion Planting in Victoria
Pair squash with Corn, Bush Beans, Nasturtium, Marigold for mutual benefit. Avoid planting near Potato, Fennel, which compete with or inhibit squash growth.
