Delta Squash is a hybrid, semi-crookneck squash variety known for it’s productivity and plant vigor. This variety produces vigorous plants that are resistant to powdery mildew and will perform even in the toughest growing conditions. The plants also have a dense bush growth habit, so you get maximum productivity with a slightly smaller footprint compared to the average squash plant. Delta Squash produces heavy yields of beautiful, yellow squash that are tender and delicious. This is an excellent variety for frying, sautéing, grilling, or just about anything you could imagine!
Squash may be direct-seeded or transplanted, although we highly recommend direct seeding. To ensure a good stand, we recommend planting squash seeds every 12″ along the intended row. Once plants emerge, thin plants to one every 2 feet. 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 the 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.
Squash are a crop that will require multiple harvests throughout the growing season. Regardless of variety, squash will have better flavor and texture when harvested on the small end of the spectrum. We recommend harvesting every 2-3 days to ensure no fruits become too large and unpalatable. When squash plants cease production, 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 squash varieties to reduce disease and pest pressure.
