To prepare for planting loofahs, choose a location with full sun and well-draining soil, preferably rich in organic matter. Start seeds indoors 2-3 weeks before the last frost date or plant directly outdoors after all danger of frost has passed. Position the plants about 1 meter apart to allow ample room for growth. Water regularly, but avoid overwatering as loofahs prefers moderately moist conditions. Note that while these guidelines are generally applicable, individual loofahs species may have specific requirements. Always research your specific type for best results.
