Luffas sponges are probably best known for use in the shower to exfoliate your skin, but they can also be used for washing dishes or windows.
If you have never done this, here is an opportunity to grow and make your own luffa sponge!
There are several species of Luffa plants that you can do this project with, and they are:
Luffa cylindrica
Luffa acutangula
Luffa aegyptiaca Mill
They are all in the Cucurbitaceae family. Most seed catalogs offer luffa seeds, so they are not hard to find.
Growing the plants:1. The plants are very easy to grow with no insect problems, but frost will kill these plants so be careful to make sure either it is warm enough out, or you give them some frost protection until all threat of frost is over.
2. They need around 4 to 5 months to grow and produce sponges that you will be able to use, so sowing your seeds now, in the spring or early summer is the best time.
3. Like many gourd and squash plants, they like full sun, regular water, and they are natural climbers so you can train the vines up a trellis or fence, or up the side of a wall or your house.
4. The fruit is edible when young, but will get very tough to eat if allowed to get too big.
5. They can get about 15 feet (4.6 m) tall.
Making the sponge:1. Harvest mature sponges in the fall; you can pick the fruit just after the first frost kills the vine, and then peel off the outer skin.
2. Cut of the ends, and then squeeze the fruit repeatedly from the middle towards the ends to remove the pulp and seeds that are inside. Some people call this “milking” the squash.
3. If seeds do come out, make sure you set some aside for next year!
4. Next, if the sponge is discolored, soak it for 5 minutes in warm water with a little bit of bleach.
5. Allow the sponge to dry thoroughly by hanging them up or placing them on a drying rack.
6. Last, make sure to clean your luffas throughout the year in the washing machine. Most luffa sponges will last for years!
Note: It is also possible to dye the luffas if you want your sponge to be a different color than it’s natural tan.
