How to Grow Serpent Gourd, Snake Gourd and other Trichosanthes Plants in the Garden
When growing Trichosanthes plants, such as Serpent gourd and Snake Gourd, from seeds it is best to start the process off indoors.
Sow the seeds in peat pots about two months before they are due to be transplanted into the garden (aim to transplant outdoors in the middle of spring).
Once sown it should take Serpent gourd from two to four weeks to germinate at a temperature of 18 to 24 degrees centigrade (64 to 75°F).
Once ready, transplant Serpent gourd outdoors singly, or at least 1.5 m apart (5 feet). Grow Trichosanthes in a sunny area, that has afternoon shade. Ideally this location should have a moist soil that is humus rich.
