3. Sowing method
The survival rate of towel gourd transplantation is low. Generally, direct seeding is adopted, with 2-3 seeds per hole, and the depth is 1-2cm. The seeds should be laid flat, and the field water capacity of the soil is 75%. If it is too dry, you can water it slightly, and cover it with hay after sowing to keep it warm and moist.

Luffa usually emerges in 4-6 days. After the seedlings are unearthed, the temperature should be lowered appropriately. If the water is insufficient at the seedling stage, it should be properly watered or sprayed, and attention should be paid to the prevention and control of pests and diseases. When the seedlings grow 2-3 true leaves, they can be planted.
