Pinetree Garden Seeds Luffa Gourd

These gourds require a long growing season, taking approximately 130 days to reach full maturity. Because of this, it is best to start them early in warm climates or use seed starting indoors if you have a shorter growing season.

While you can grow them along the ground, a trellis is highly recommended. It keeps the fruit off the soil, which prevents rot and encourages the gourds to grow straight, resulting in a more uniform shape for your sponges.

Once the gourd turns brown and feels lightweight, harvest it and peel away the outer skin. Shake out the seeds, rinse the fibrous interior thoroughly, and let it dry completely in the sun before using it as a scrubber.

Because these vines can reach up to 15 feet in length and are heavy feeders, they are best suited for in-ground planting in fertile soil. If you must use a container, ensure it is very large, provides a sturdy support structure, and receives consistent fertilization.

Luffa seeds require warmth to germinate successfully. Aim for a soil temperature between 70 and 90 degrees Fahrenheit, and keep the soil consistently moist until you see sprouts, which typically appear within 7 to 10 days.

To ensure proper airflow and accommodate the vigorous growth of the vines, space your plants about 36 inches (91.44 cm) apart. If planting in rows, allow for 48 inches (121.92 cm) between each row.
