- In Zones 9 and 10, you can direct seed or transplant out your squash. We recommend direct seeding into freshly irrigated soils.
- To direct sow, plant seeds in debris-free, well-worked soil that has been deeply watered. Cover with 1″ of finely sifted soil.
- If you are planting seeds in starter pots, plant seeds into thoroughly moist high-quality seed starting soil. Place seeds on top of the soil and cover with 1″ of finely sifted soil.
- Once your squash has germinated and the first set of true leaves show, fertilize with an organic liquid fertilizer. When the plants are 3-4″ tall you can plant them out into the garden. Space at least 12″ apart.
- Squash should be planted into deeply irrigated, fertile soil. In Zones 9 and 10, adding tons of compost will help create a healthy soil structure and keep soil moistures in.

Growing Squash in Containers
- Squash plants like to grow across the ground but alternatively can be grown up a trellis if hanging fruit are supported. If growing in a container, make sure your container is at least 20″ deep. Keep in mind containers will dry out faster because they have more surface area and less soil to hold onto moisture. Mulch heavily on the top layer of soil in the pot to keep the soil from drying out or heating up too much.
