Loofah (Luffa sponge) Profile
Loofah (Luffa sponge) are best known as bath brushes, but they actually started out as gourds like cucumbers. Two types of Loofah (Luffa sponge) are commonly grown in Florida: angled luffa and smooth-fruited luffa. Both types of Loofah (Luffa sponge) can be eaten when young, but most gardeners grow them for their fibrous insides, which are great for cleaning houses and bodies.

Loofah (Luffa sponge) History

Loofah gourds are thought to be native to India. The plants and the sponges that come from them were likely introduced to western countries like the U.S. in the 1800s. Loofahs were given names like “vegetable sponge” and “poor man’s dish rag.”
The seeds were offered for sale in drug stores so that people could buy them and grow their own novelty plants. They were used not only for bathing but also for scrubbing in the kitchen.
Before other synthetic materials were created, loofah fibers were sometimes used as insulation, packing material, and mattress stuffing.
Loofah gourds were also grown as an edible plant, especially by Chinese immigrants. The fruits were harvested when they were small and cooked on their own or in vegetable dishes. Their flavor is a combination of cucumber and zucchini.

Ecological Habits of Loofah (Luffa sponge)

The Loofah vines must have a strong trellis system to climb. The vines prefer to grow tall and will do well on a 6 to 10 feet (2-3m) high trellis. The vine length can exceed 30 feet (9m). 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. Loofah (Luffa sponge) produce large yellow flowers.

Loofah (Luffa sponge) Distribution Area

Luffa sponges don't come from the ocean. And they're not from manmade materials. Rough-textured exfoliators originate from luffa: dried fiber from the vegetable of the same name. Luffa or loofah (botanically Luffa aegyptiaca) is a vine-grown member of the pumpkin, squash and gourd family, Cucurbitaceae. Centuries ago, the luffa plant was brought to this country by European settlers. They planned to domesticate it in the New World. Though a few varieties are edible, most were cultivated for their utilitarian value.

How to Grow and Care for Loofah (Luffa sponge)

How to Grow Loofah (Luffa sponge)

  • With Seeds
Loofah seeds don't germinate quite as easily as cucumbers or courgettes, so sow a few extra to be sure to have enough plants.
Soaking the seed for a few hours in lukewarm water ahead of sowing can help to encourage better germination. Fill your pots up loosely with compost and tap down lightly once or twice.
Hold the loofah seed, sides on, between finger and thumb and push it sideways down into the loose compost, about 1.5cm deep.
Tap the pot again to settle the soil over the hole. Make sure you pop a label in to avoid mix-ups later.
Then the pots need heat, lots of lovely heat! 25 degrees Celsius of heat. So, putting your pots into a heated propagator box is best for success.
Once you've sown your seeds and placed them into the propagator be sure to water them water them. Avoid overwatering though, as this can cause the seeds to rot.
Try to resist the temptation to keep taking the lid off for a peep, as this will let the built-up moisture out of the propagator.
Germination won't take long at 25 degrees, so check in a week but they may take 2 or even 3 weeks at cooler temperature. Too cool a temperature and the seed may rot rather than germinate, so the warmth is very important.
Once the roots are starting to show through the holes at the base of the pot it's time to pot them up. We pot ours into bucket-size pots but if your indoor space is limited you could use smaller ones and increase the size as the plant grows.

How to Care for Loofah (Luffa sponge)

  • Light
Luffa needs at least six or more hours of full sun—the more the better.
  • Soil
To grow healthy and vigorous, your luffa gourds will require the well-drained, loam or sandy ground, with a pH of 5.5 – 6.8. It is always a good idea to do a soil test before planting your veggies.
  • Water
Loofah sponges need moisture to sprout, and their seedlings need time and adequate watering for proper roots’ development. Never let the ground get too dry. If the pot is small, you need to water the soil every day, but you should take care not to over water. Keep watering your plants once you transplant them in the garden. On average, they will need 1 inch (2.5 cm) of water a week. Consider installing the drip-irrigation system for your luffas.
  • Temperature and Humidity
Luffa needs warm to hot weather, in cool weather, its growth will slow down.
  • Fertilizer
Add organic matter to the soil before planting, and add nitrogen-rich fertilizer two to three times during growing season.

Varieties of Loofah (Luffa sponge)

There are two species of luffa – Luffa acutangula, best for flavour, which looks like a fluted green barrage balloon about 28cm/10in long and L..cylindrica, which looks very similar to a courgette, except that the skin is smooth, shinier and fairly hard rather than slightly bristly. Both have similar leaves, deeply lobed and sprawl rather than climb, using tendrils. Individual plants have flowers of a single sex. Inside both species of luffa is a creamy flesh with many small seeds, similar to a courgette in texture and flavour. The two species will hybridise if grown even at considerable distances apart, so if you want to save seeds it's better to only grow one species at a time. The smooth luffa tends to produce fruits in shortening days (after midsummer in the UK) while angled luffa is unaffected by day-length. At present there are no specific cultivars sold in the UK, but a range of varieties exists elsewhere, including plants with long, short or rounded fruits, and differences in length of time from seed to fruit production. Some cultivars are selected for the quality of their hard internal fibres, used for sponges, while others are grown for medicinal properties, particularly in China. ‘Satiputiya’ is a hermaphrodite variety.

Loofah (Luffa sponge) Common Pests/Diseases

Loofah (Luffa sponge) plants can be attacked by the same insects and diseases that other winter squash and gourds are beset by.
Cucumber beetles, squash vine borers, and squash bugs are the main insect pests. Regularly check your plants for signs of an invasion. You can also check the underside of leaves and remove eggs before they hatch.
Squash vine borers can be especially detrimental to your plants because they bore inside the vines and will eventually kill them. You can prevent this in young plants by wrapping strips of row cover around the base and up the vines as they grow.
If you notice little piles of shavings at the base of your plants or along the vines, you probably have a borer already inside. You can cut it out with a sharp knife by slicing open one side of the vine. After you remove the culprit, bury the sliced section under soil if possible.
The most common disease problems are fungal pathogens like powdery mildew. These usually aren’t bad enough to kill your plants, but the best prevention is to space plants properly and avoid getting the leaves wet as much as possible.

Loofah (Luffa sponge) Design Tips

The bright flowers are also attractive, opening in the morning, and attracting honey bees, blue-banded bees and carpenter bees into the garden. If you've got an unsightly shed or a bare fence, you might like to grow luffas as a productive screen. They're best grown on a pergola so the fruits hang down. But grow them as an unusual gift because they are always appreciated.

Loofah (Luffa sponge) Harvesting

Harvest when the skin feels thin and loose, as if it is going to come of easily. Leaving it to dry in the sun can make it easier to peel. Many people find it easier to cut the bottom off before peeling and shaking/banging/tapping out the seeds into a bucket, there should be a few hundred in a good sized loofah. The banging and tapping will also help to loosen the skin making it easier to peel. Peeling the loofah itself is not that dissimilar to peeling a banana. Once peeled wash thoroughly and then dry out completely before storing to avoid it going mouldy. It can then be cut into different shapes as scrubbing pads for pots and pans or left whole as a back scratcher.
