The best time to germinate bitter gourd seeds is when they are fresh. Knowing when bitter gourd seeds are ready for sowing is very easy as the fruit dries, splits open, and shows seeds in a golden yellow background.

Don’t forget to protect your hands by using gloves as bitter gourd seeds are toxic if ingested. Note that sprouts must arise within 10 to 14 days. For quicker germination, soak the bitter gourd seeds in water before sowing. 

Soak bitter gourd seeds in clean water for approximately 25 minutes. Keep in mind that if seeds are still floating after the end of the immersion, throw them away.

Next, take the bitter gourd seeds and wash with boiled water. Drain and leave them open until it dries on its own. 

Another method to accelerate germination is by thinning seed skins. Hold the bitter gourd seeds and rub gently on fine sandpapers. Once the seed skin begins to change colour, stop rubbing. 

Keep in mind that rubbing one side of the seed allows the germination process and prevents damage to the seed.

Once you stop scrubbing the seeds, place them in boiling water for no more than four seconds, and then carefully drain them on a sheet of paper towel for a couple of minutes before sowing. 

Please note that the bitter gourd seeds germination ideal temperature is between 30-35° Celsius.

Sowing bitter gourd is easy; all you have to do is make about 1.27cm deep holes in the vegetable garden. Make sure to space them 10cm apart to secure the vines and ensure they don’t eat each other. 

Make sure not to sow more than one bitter gourd seed in each hole or pot to leave room for the roots to expand. Remember to water the bitter gourd plant to keep the soil moist continually.

Consider starting bitter gourd seeds inside, and once seeds germinate, transfer them to a sunny location in your garden.

The Bottom Line

The key to accelerating the germination process is high temperatures and adequate moisture. Remember, you can soak bitter gourd seeds overnight in water or thin seed skins before sowing for quicker germination. 

It takes approximately 25 to 30 days for the plant to start flowering. Once the vine is 1.80 – 2.50 meters long, cut the growing tips.

Doing this strengthens the plant and boosts the growth of side branches producing more flowers and fruits.
