Peeling last season’s homegrown luffa never gets old! From vine to sponge - this is one of the most satisfying crops we grow. Luffa needs a long growing season, so if you’re in a cooler zone, starting seeds indoors soon is key. By the end of summer, you could be peeling your own homegrown sponges! Check your personalized seed-starting dates in the Seed to Spoon app and add luffa to your 2026 garden plans! Grow your own bath sponge this year! You’ll never look at a store-bought one the same again
