Here are the steps that you need to follow to grow a loofah from seeds:

Obtaining the seeds

You can obtain a loofah seed from an adult loofah fruit. If you don’t own a loofah plant, you can easily obtain seed from your local store.

Soak the seeds overnight before sowing them. You can also thin out the skin of the seed with the use of sandpaper. Thinning out the coating of the seed will help hasten the seed’s germination. Use warm water to soak them and leave them in that state for 24 hours.

Sowing the seeds

Fill the small plant pots that you prepared with compost and sow the loofah seeds 1 to 2 centimeters deep, then water them well. Place the pot in the large plastic box and place the plastic box in a sunny spot with the lid on but slightly open. A loofah seed typically germinates in about 20 days at a temperature of 25 to 30 °C.

You can speed up the seed’s sprouting and germination process with the use of a heating mat. Loofah plant is a heat-loving plant and using a heating mat can greatly enhance the seed’s sprouting process.


Once the loofah seeds start to sprout leaves, you can carefully transfer your loofah plants to larger pots outdoors. Place your loofah plant in an area where it is sunny but also has a lot of shade.


In choosing the right location for your growing loofah plant, keep in mind that these plants can grow up to 30 feet long. Finding a location with enough room for your loofah plants to grow freely is very crucial. It is necessary to place supports that they can climb because loofah plants are known to be excellent climbers and will climb any sturdy supports that they can grab.


Once the seedlings develop their first set of real leaves, you can begin fertilizing them. You can choose between compost, animal manure, and even commercial fertilizers. The most recommended is the liquid organic fertilizer as it consists of essential nutrients that your loofah plant needs and has beneficial microorganisms that can also help recycle organic matter. These microorganisms are very helpful in the degradation of substrates during fermentation.

Monitoring and Watering

As your loofah plant grows, you also need to water the plant regularly to keep the soil moist but also keep in mind to not soak your loofah plant in too much water so that it won’t drown. As the plants continue to grow, you can use the twines and canes to help support the plant’s vines and branches.

Do not hesitate to water your loofah plants if you start noticing that the soil around them dried up. Be careful not to overwater your loofah plants as this can cause their roots to rot and ultimately kill them. Instead, deeply water your loofah plant so that the water is dispersed evenly all over the pot.

Fruit Bearing

About 100 to 120 days after planting your loofah plant, it will start to mature and start to produce yellow flowers. These flowers will soon become the long and green fruits that the loofah plant will produce.


Hand pollinating is advised to ensure that the first flowers that your loofah plants produce are properly pollinated and can turn into fruits. It is very easy, you only need to spot the difference between the male and female flowers. Use a clean and dry small paintbrush to transfer pollen from the male to the female flowers of the plant. You can hand pollinate your loofah plants every couple of days a week.


There are two ways to harvest a loofah fruit. The first one is to harvest as a young and green vegetable that is usable for home dishes like stir-fries, stew, or curries. The second one is to let them mature enough that their green skin turns brown. You can use the old loofah fruit as a sponge.

To make a loofah sponge, peel your homegrown loofah fruits that have dried up. Remove the seeds inside the loofah fruit. You can also use these seeds to grow a new loofah plant once its growing season starts. After peeling, the whole body of the loofah fruit can be turned into a sponge. Rinse your loofah sponge clean and if they are still discolored, you can soak them in a bleach solution for about half an hour.
