The Loofah Plant (Luffa) is a vegetable vine from Southeast Asia that produces the fibers of Luffa Sponges. If you are looking for sustainable and biodegradable home and body care sponges, growing your own Loofah sponges may be the perfect plant for your garden.
This guide discusses how to plant and care for your Loofah Plant and common problems that you may encounter.
About Loofah Plant
Loofah, Loofa, or Luffa is a member of the Cucurbitaceae family, or the cucumber family. The Luffa vines are native to Asia, are fast-growing, and have a long growing season. Also known as sea sponges, these vigorous vines are great climbers and will trail up a trellis to create a beautiful canopy in your home garden.
The most popular varieties of Loofah are the Luffa Aegyptiaca and the Luffa Acutangula (Angled Luffa). These vegetables in the gourd family contain natural fibers that are often used as scrubbing material. The Asian vines grow thick and produce bright yellow flowers that attract pollinators in the late summer.
The Luffa plant fruits are slow to mature and are ready for harvest in late autumn.
Can you eat Loofa plants?
Yes! Young luffa plants are, in fact edible. Luffa plants are part of the cucumber family, and young fruits resemble okra and can be used in cooking along side other squashes, cucumbers.
Loofah Plant Benefits
The plant’s fruit (sometimes called Chinese Okra) is technically edible and can be used in soups, stir fry, similar to other summer squashes.
However, the fibers of the luffa sponges are more often used as scrubbers. These fibrous, natural sponges are dried and also used as fall decoration.
Loofah Plant Varieties
Angled Luffa (Luffa acutangula) - This variety of Luffa has ridged edges or angled edges native to central and eastern Asia.The young fruits are edible raw or cooked, and mature ones are used as scrubbers.
Luffa Aegyptiaca/Luffa Cylindrica - The Egyptian Cucumber or the Vietnamese Luffa has smooth edges and is more cylindrical in shape. Their fruits are much thicker, more like cucumbers opposed to Angled Luffa. This one is more commonly used as a sponge gourd.

How to Grow Loofah Plant

The Loofah plant grows well in USDA hardiness zones 7 and above. It prefers full sun and moist soil that is rich in compost, manure, or mulch. This vine will climb a sturdy trellis and create a welcoming shade canopy for a full sun location.
The vine will grow quickly and spread over a large area. The beautiful yellow flowers will bloom in mid-summer and the fruit will mature in the late fall. This gives you the attractive vines for a longer time frame than most summer fruits and vegetables.
When & How To Plant Loofah Plant
Soak your loofah seed for 24 hours before planting to “wake” them up. You can plant the seeds in a seed starter mix or directly in the ground (we recommend this method).
If germinating indoors, they will do best when planted in 85℉, so you may want to using a heating mat. You will want to start Loofah seeds four to six weeks before the danger of last frost has passed or when you plan on planting them outdoors.
If growing outdoors, plant your Loofah seeds or sprouted seeds in the ground after the last frost in the early spring.
Plant Loofah seeds ¼ inches deep into soil and gently sprinkle soil over the seeds. Cover with plastic to maintain humidity and seed germination will occur within 7-14 days.
Luffa seeds should be planted 8-12 inches apart and will take 120-200 days to fully mature.
This plant will attract pollinators but it may benefit from manual pollination as well.
When do I harvest Loofah plants?
Loofah is best harvested in the fall time when the fruits are tan in color and light. This is a sign that the fruit, itself, has fully dried and is best ready to produce scrubbers.
How to Make Loofah Sponges

Once the Luffa fruit is mature (approximately 12” long), you can harvest the fruit and let it dry out.
- Open the skin of the mature luffa gourd and shake out the seeds.
- Peel back the skin and remove the sponge-like fibers.
- You can soak it in a diluted bleach solution
- You can cut the loofah sponges into different sizes and use on your skin or household items such as dishes, counters, and appliances that may need extra abrasion.
How to Care For Loofah Plant

Loofah vines are very easy to care for once they are established. They will grow sturdy vines up to 30ft long and create lush ground or canopy cover. Keep in mind that you’ll need plenty of space for these vines to thrive, and we don’t recommend growing them indoors.
💧 Water
Loofah plants need moderate amounts of water and prefer consistently moist soil. Be aware ov overwatering which can lead to soggy soils that can make loofah plants susceptible to fungal diseases like root rot.
Avoid watering the foliage directly because this can cause moisture buildup leading to diseases like leaf spot.
In the warm months you may need to water every 1-2 days to maintain moist soil. As the weather cools in the fall, watering needs may reduce, however, the large plant may continue to require watering every few days.
☀️ Sunlight
Full sun for 8-12 hours is ideal for the Loofah Plant. It loves to sunbathe and will reward you with long vine, large leaves, and beautiful yellow flowers.
🌡️ Temperature and Humidity
Even though this is a tropical plant, it can tolerate temperatures in the mid 50s. It is a fall harvest vegetable, which will ripen in mid-September to mid-October. After harvest, the vines will die back.
Overwintering Loofah Plant
Once harvest is complete, the Loofah vines will die back. This is an annual plant like many fruits and vegetables and it will not grow back in the spring without replanting seeds. Be sure to wait until after the last frost to plant the seeds the following year.
🌱 Best Soil for Loofah Plant
Loofah plants like moist soil that are rich in nutrients. Adding compost, manure, and/or mulch to the soil will encourage growth of a healthy plant. Keep the soil moist but not soaking wet throughout the growing season.
🌻 Fertilizer
Loofah plants prefer an NPK ratio of 1-2-2, so a fertilizer like 5-10-10 or 10-20-20 is ideal for fertilizing during the growing season. You can fertilize your plant once a month during the summer.
Loofah plants prefer higher phosphorus and potassium levels will encourage stronger roots and better blooms.
😎 Pruning and Maintenance
For best results, you will want to pluck the first male flowers of this vine. You may also consider pruning the vines to keep them shorter and encourage more branching and less length. This will encourage the plant to push out more fruits instead of spending its energy on leaf growth.
