Grenade Squash is a hybrid zucchini, summer 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 resistance 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 help 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.
