Luffas are gourds, and the only source of vegetable sponge. Although they can be eaten like zucchinis or cucumbers when young and tender, allowed to grow to their full maturity, they will give you a very good exfoliating sponge. The more mature they are, the better the sponge fiber quality. Some smaller ones may mature more quickly yielding a small soft sponge good for washing delicate skin.

Luffa is quite easy to grow, and when the fruits are still young, they're actually quite delicious.

Luffa is quite easy to grow, and when the fruits are still young, they're actually quite delicious.

Luffa gourds also called "loofah", are sometimes called "vegetable sponges" The name comes from luff, the Arabic word for this plant. Luffa gourds are grown primarily for their fibrous tissue skeleton, which is commonly used as a bath sponge, but young Luffa sponges are the fibrous interiors of the fruits of the luffa sponge gourd plant {Luffa aegyptiaca Mill}. A tropical member of the Cucurbitaceae, the luffa sponge gourd plant is an annual vine with tendrils and large, cylindrical fruit that are edible when young. When allowed to fully ripen, the flesh becomes quite fibrous, and then dries out and becomes light, and the rind will be hard. The dried out flesh frees up many small, flat, smooth black seeds, that will rattle inside. Luffa is a hot weather plant and growth slows in cool weather. The flowers appear over an extended period of time blooming sequentially as the vine progresses. The vines can grow 30 feet(10m) or more over the growing season.

Here are some photos and videos with step by step descriptions of luffa sponge gourds being planted and grown in my organic garden.

. Luffa Seeds Planting . The most important step is to select good seeds for planting





Part of the reason I had such good success with my germination rate is that I harvested the seeds myself, from my own Luffa, only a few months ago, and i have fresh seeds. But if you don’t have that luxury you can buy a packet of luffa seeds on Amazon











Sow germinated seeds, two to three per pot. they will show up two or three days later if you're in a hot climate, or up to four days later in a cooler one.

Grow the seedlings in a pot until they're a reasonable size, thin to one plant per pot after the first true leaves appear.





The seedlings grow slowly while the roots develop. Provide lots of sun and don't let the soil get too dry. Small pots may need water every day but don't over water.





. Growing Luffa .

To grow luffas, you'll need well drained, rich soil with a high content of compost and organic matter as chicken manure. Luffa prefer slightly acidic soil with a pH of 6.0 – 6.8 . Luffa gourds require a well-drained soil in a location where they will have full sun and good air circulation.









Vigorous luffa vines will require plenty of water and fertilizer, so water deeply once or twice per week. Loofah vines must have a strong trellis system to climb. The vines prefer to grow tall and will do well on a 6 to 30 feet (10 m) high trellis.









The Loofah sponges can get heavy, so the more places the vine tendrils can hold on to the better, it may need to be supported so that it doesn’t pull the whole vine down. Shortly after training the vine on the trellis, you may find lots of flowers on the plant.









The flowers appear over an extended period of time blooming sequentially as the vine progresses. All gourd varieties produce male and female flowers. The male flowers form first before the female flowers so remove the early flowers to encourage the vine to grow and become more sturdy before fruiting. This will improve the quality of the gourds that grow. A healthy vine growing in rich soil will give a good crop of gourds over the growing season.

Luffa blooms are bright yellow and about four to five inches across. Abundant male flowers open pretty early in the season, followed some weeks later by periodic female blooms. The honey bees will spend much time visiting these, gathering valuable pollen.

. Female Luffa Flower .





The female flower can be distinguished by the small fruit attached to the flower. Female flowers are large, solitary and have long, bulbous stems, female flowers can benefit from hand pollination. This is best done in the morning . To pollinate, pull off a male flower and rub it gently on the female or use a cotton swab or fine paint brush to transfer pollen. Unpollinated flowers will fall off and pollinated ones will form the start of a luffa at the base of the female flower.





. Male Luffa Flower .





The male flowers form clusters which flower one at a time on a thin stem.The flower is just plain without any fruits.





If you don’t have a big vegetable garden there is No Problem. You can plant Luffa plants in a big pot on a balcony or backyard as long as you provide the vines with something to grow on. Don’t forget they can easily get to be 30′ long under the right conditions.





. Insects And Pests .

Luffa sponges are members of the cucurbita family, which includes pumpkins, squash, watermelon and cucumbers. They are susceptible to a wide range of insects. They include the cucumber beetle, aphids, slugs and snails and squash vine borers.

. Disease . luffa sponges are affected by a range of fungus and viruses. Most notable is Downy and powdery mildews. Start treatments when the hot and humid summer weather begins in your area.

. Harvesting Luffa Sponge .





You can harvest luffa sponges when they are brown. If they're still green they'll feel heavy, as they dry they lose their weight . They'll be ready to peel when they turn brown, they are light in weight and you can peel the crisp skin off. Be sure to pick and peel the fruit immediately if they get hit by frost. Fruit that aren’t fully mature don’t have enough tough fiber to make a good sponge





When you have all your luffas peeled and all the seeds out, soak all of them in a bucket of water with a tablespoon of liquid bleach added. This will kill off any mould spores that might be lurking.





Whether you choose to eat young luffas, or hold fruit on the vine to mature for making your own luffa sponge, you will enjoy experimenting with this unique vegetable. Allow the luffa sponges to dry completely in the sun and make certain that sponges are completely dry before storing or mold may grow on any remaining sap. Dried luffas can be stored for years as long as they stay dry and dust free. These natural sponges are extremely durable and will last for years.

. Uses for Luffa Sponges .

These natural cellulose fiber wonders of the vegetable world have many uses. Luffa sponges are most excellent in the bath or shower. The exfoliating action leaves your skin feeling the cleanest and tightest it could possibly be. Luffa sponges are great for washing and cleaning almost everything, including cars, plastic buckets, and anything that needs scrubbed .

. Caring For Luffa Sponge .

1 . Rinse your luffa after each use. Use hot, clean water, making sure all the soap is gone.





2 . Dry the luffa completely between uses. Put it in a place with good circulation so it can dry completely.





3 . Replace your luffa every three weeks.

. Precautions .

Luffas are vegetable matter that is dry and hard when wet. So your old and hard luffa may need to retire anyway as they retain bacteria after a few weeks use and then need to be replaced.
