Sponge gourds require consistent moisture. Water deeply at the base of the plant, especially during dry periods and when fruits are developing. Avoid overhead watering to minimize fungal diseases.

Allow the top 2-3 cm of soil to dry out slightly between waterings.

Pruning is minimal for sponge gourds. Focus on removing any yellowing or diseased leaves.

You can also pinch back the tips of vines if they become overly rampant to encourage bushier growth and potentially more flowering sites. Ensure good air circulation around the plant.

Propagate sponge gourds from seeds. Start seeds indoors 3-4 weeks before the last frost or sow directly into the garden after all danger of frost has passed and the soil has warmed to at least 21°C.

Seeds germinate best in warm conditions.

Repotting is not typically necessary for Luffa aegyptiaca grown outdoors as it's an annual vine. If grown in containers, ensure pots are large enough to accommodate mature root systems.

Repotting might be needed if plants are started indoors and become root-bound before transplanting.
