Organic Dark Star Zucchini Seeds

Dark Star zucchini is a unique summer squash grown for its “open habit” which makes it easier to locate any hidden zucchini and harvest regularly. We are happy to offer this interesting and prolific zucchini, a rare variety produced by our friends at Feral Farm.

Planting by Zones

Zones 9-10

• Squash should be grown in the warm season when soils are at least 70° F.

Zones 2-8

• Direct seed in the spring once soils have warmed.

Planting Dark Star Zucchini

• 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.
• Fertilize with an organic liquid fertilizer once your squash has germinated and the first set of true leaves show. When the plants are 3-4″ tall, you can plant them out into the garden. Space at least 12″ apart.

Growing Dark Star Zucchini

• 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.
• Mulching heavily around your plants will also help with weed suppression and moisture retention.
• Pollination is key to producing squash. You should hand pollinate your squash if you doubt you have good pollination.

Harvesting Dark Star Zucchini

• Squash is best harvested at peak ripeness. There are two ways to know that your fruit is ready; this is by knowing what kind of squash you are growing.
• Summer Squash is eaten when it is young and tender. You want to be able to pierce the flesh of the squash with your nail. These are crops like zucchini and scallop squashes, among others.
• Winter Squash will mature with a hard outside and can keep for several months through the winter. Hence the name! These squash you want to fully mature on the vine.

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.

Southern California Pro-tips

• Mulch heavily around your squash plants to ensure the soil does not dry out or overheat.
• Do not overhead water as this promotes foliar diseases.
• Grow at least two squash plants to ensure good pollination.

Companion Flowers/Crops

• Squash are aggressively growing plants that look wonderful with cosmos, zinnias, and sunflowers. If you love the flavor of zucchini, try our Ronde De Nice Squash. It is similar in flavor and texture to zucchini but has a round shape, making it great for veggie lasagna.
