Growing Instructions
Starting your seeds
You can start luffa sponge seeds indoors using a heat mat to encourage germination. Once the seedlings sprout and grow a few sets of leaves, move them outdoors. Keep the soil moist and provide 6–8 hours of sunlight daily. When direct sowing luffa sponge seeds, plant them about 1/2 inch deep in well-drained soil. Space them 12–18 inches apart to allow for proper vine growth and support.
Harvesting your seeds
To harvest luffa, wait until the fruit reaches a length of 6 to 8 inches. Harvesting at this stage ensures the luffa is still young and tender. Use sharp scissors or pruning shears to cut the fruit from the vine, leaving a small portion of the stem attached. Harvesting regularly promotes ongoing fruit production.
