Additional Information You will not need to grow many of these plants as they are quite prolific producers unless you have lots of friends and family that enjoy zucchini. The bush habit is rather closed and can make harvesting a bit of a challenge. Sow zucchini in the garden as early as 2 weeks after the last average frost date in spring. To get a head start on the season sow zucchini indoors about 3 weeks before you transplant it into the garden. Sow successive crops every 2 to 4 weeks to extend the harvest and to protect against crop loss to insects or disease. Time all plantings so that squash comes to harvest before the first frost in fall. By the time the Black Beauty Zucchini reaches its mature size, they can be monsters that can be 76 cm (30”) long with a tough hide.
