How To Grow Loofah Sponges From Seeds

Loofah sponges are an easy to grow gourd that will make an awesome addition to your garden. They are useful and interesting. 

Loofah gourds require a long growing season, so if you live in the northern hemisphere, you will need to start your seeds indoors.

You can purchase luffa seeds at many online retailers. I purchased mine on ebay for just a couple of dollars. They look kind of like watermelon seeds.

So, let's grow some loofahs. 


- loofah seeds
- nail clippers
- paper towel
- ziploc bag
- a few small pots
- potting soil
- a tray
- spray bottle with water


1. Examine the loofah seeds. You will notice that one end is round and the other is slightly pointy. Using your nail clippers, clip off the very edge of the rounded side. This will allow water to easily enter the seed and speed up germination.

2. Fold the seeds into a wet paper towel and place them in a sealed ziploc bag.

3. Place them in a warm area that's above 70 degrees.

4. Check daily to see if the seeds have started growing and make sure to keep the paper towel moist. They should start to grow in 1-3 days.

5. Once they have started to sprout, transfer them into small temporary pots filled with potting soil. Plant them root side down. I planted 2 seeds per pot. They don't need to be planted very deep. Just enough to cover them gently with soil. Mist them generously with water and then fill the tray under the pots with half an inch of water to keep them moist.

6. Place the tray in a sunny window, south facing is the best. Lots of light will prevent the seedlings from being spindly. Mist them every day until they start to grow.

8. Water the sprouts carefully and whenever necessary to ensure they stay moist but don't drown them.

7. Once they have a few sets of leaves and there is no danger of frost in your area, you can plant them outside in a sunny area. Care for them the same as you would any other variety of climbing squash.

8. Once they start to flower you can hand pollinate to increase yields. Learn how to do that HERE.
