Kid Seed Co. Luffa Gourd

Luffa gourds require a long growing season, typically taking 150 to 200 days to reach full maturity. Because they need significant heat to develop, it is best to start them early or ensure you live in a region with a long, warm summer.

Yes, luffa is a vigorous vining plant that performs best when given vertical support. A sturdy trellis, fence, or arbor is essential to keep the heavy gourds off the ground, which helps prevent rot and ensures the fruit grows straight.

Once the gourd turns brown and feels lightweight, harvest it and let it dry completely. You can then peel away the outer skin to reveal the fibrous interior, which should be shaken to remove seeds before rinsing and drying for use.

While you can direct sow in warm climates, gardeners in cooler zones should start seeds indoors 3 to 4 weeks before the last frost. Luffas are sensitive to cold, so wait until soil temperatures are consistently warm before transplanting them outside.

These vines are aggressive growers and can easily reach 10 to 15 feet in length. Space your plants at least 4 inches apart if planting in a row, but ensure they have plenty of room to climb and spread horizontally if you aren't using a vertical support system.
