Squash - Summer & Zucchini

Summer Squash and Zucchini Seed

Zucchini and summer squash like warm temperatures, plenty of sunlight, and a fertile, well-drained soil. Because they are quick to harvest, 'summer' squash are easy for Northerners to grow. Best germination is in warm soil (70-80F). If starting indoors, use deep peat pots so as to not disturb roots when transplanting. Sow 1/2 to 1 inch deep, thin to 24-36 inches apart. Many folks use raised rows or hills to plant the seed to avoid rotting the seed and crown. Bees and insects are critical for good pollination and fruit set. SPECIAL CAUTION: Untreated zucchini and squash seed is particularly susceptible to failure if planted in soil that is too cool or wet.
