Grenade Squash is a hybrid zucchini squash variety that produces beautiful, egg-shaped fruits on prolific plants. These squash are highly-desirable in the culinary industry for their flavor and bright yellow coloration. These can be sliced like traditional zucchini varieties, but are great when sliced in half and grilled.
Grenade Squash has vigorous plants with an excellent disease package including resistant to squash mosaic virus and watermelon mosaic virus. The plants have an open bush growth habit which makes for easy harvesting. The plants also have few spines which helps to keep the fruits blemish-free during harvesting.
Grenade Squash may be direct-seeded or transplanted, although we highly recommend direct seeding. To ensure a good stand, we recommend planting seeds every 12″ along the intended row. Once plants emerge, thin plants to one every 2 feet. Winter Squash can be susceptible to plant diseases like downy mildew and powdery mildew if leaves receive excess moisture. As a result, we recommend using drip irrigation on winter squash to reduce plant moisture and feed plants more effectively. During periods of heavy rainfall, using a fungicide like Liquid Copper can help to alleviate disease pressure as well.
Winter Squash is a crop that will produce a one-time harvest at the end of the growing season. They should be harvested when plants die back and the fruits obtain their full color. Stem hardness is also an indication of fruit maturity. Once stems harden, fruits are ready for harvest using a set of pruning shears. Winter Squash can be stored in a cool, dry place for several months, depending on variety and sugar content. Once fruits are harvested, remove the plants from the garden to prevent any fungal spores from overwintering and becoming a problem in future years. Proper crop rotation is extremely important with all pumpkin varieties to reduce disease and pest pressure.
