Hey there fellow gardeners! I’ve been growing and harvesting loofah (also spelled luffa) for several years now, and let me tell you – there’s nothing quite like producing your own natural sponges. Today I’m gonna share everything I’ve learned about harvesting these amazing plants properly.
What is a Loofah Plant?
Before we get into picking, let’s quickly talk about what these plants are. Loofah comes from the gourd family, which includes cucumbers and squash, and its long, fibrous fruits can be used as natural sponges. The scientific names for these plants are Luffa aegyptiaca and Luffa cylindrica.
When to Harvest Your Loofah
Timing is super important when harvesting loofah Here are the key signs that your loofah is ready
- The gourd turns from green to yellow or light brown
- It feels lighter in weight compared to when it was green
- The skin begins to feel loose or papery
- When you shake it, you can hear seeds rattling inside
- The gourd feels slightly soft when squeezed
Pro tip: Don’t wait until the gourd is completely brown and dry on the vine – this often leads to moldy sponges, especially in humid climates.
Step-by-Step Harvesting Guide
1. Gathering Your Tools
You’ll need:
- Sharp pruning shears or knife
- Garden gloves
- Large bucket or container
- Garden hose with spray nozzle
2. Picking the Loofah
- Cut the loofah from the vine using your pruning shears
- If possible, harvest in the morning when temperatures are cooler
- Handle gently to avoid damaging the fibers inside
3. Peeling and Cleaning Process
Here’s my tried-and-true method:
-
Give the skin a light squeeze if it’s still a little green but turning yellow. It should feel slightly soft.
-
Remove the skin:
- For softer loofahs: The skin should peel off easily
- For tougher ones: Soak in water for 5-10 minutes to loosen the skin
- Start from the bottom and peel upward
-
Clean out the seeds:
- Cut off one end of the loofah
- Shake out the seeds (save them if you want to grow more!)
- Use water pressure to remove remaining seeds
-
Wash thoroughly:
- Use a strong water spray to remove the slimy sap
- Continue spraying until water runs clear
- You might need to squeeze and rinse several times
4. Drying Your Loofah
This step is crucial for preventing mold:
- Place on a drying rack or mesh screen
- Position in a well-ventilated area
- Keep out of direct sunlight
- Rotate occasionally for even drying
- Allow 2-3 days for complete drying
Common Problems and Solutions
| Problem | Solution |
|---|---|
| Mold spots | Harvest earlier next time; use bleach solution if needed |
| Too fibrous | Harvest when younger |
| Won’t peel | Soak longer in warm water |
| Seeds stuck inside | Use stronger water pressure |
Tips for Different Climates
Warm Climates
- Harvest before complete browning
- Watch for mold in humid conditions
- May need faster processing
Cold Climates
- Harvest before first frost
- Can allow to dry more on vine
- May need to ripen indoors
Storage and Use
Once your loofahs are completely dry:
- Store in a dry, well-ventilated area
- Keep away from moisture
- Can last several years if properly dried
- Cut into smaller pieces as needed
My Personal Experience
I gotta tell ya, my first attempt at harvesting loofah was pretty interesting (read: messy). I waited too long and ended up with some moldy ones. But hey, we learn from our mistakes! Now I know to harvest them when they’re just starting to yellow, and I’ve gotten much better results.
Final Thoughts
Growing and harvesting your own loofah is super rewarding. Sure, it takes some practice to get the timing right, but once you do, you’ll never want to buy store-bought sponges again! Just remember – don’t wait too long to harvest, keep things clean, and make sure they dry properly.
Feel free to share your loofah growing stories in the comments below. And remember, if you’re just starting out, don’t be afraid to try new things. That’s how we all learn.
Happy harvesting, y’all!

How to Dry Green Loofah / Luffa
- Put on rubber gloves and start peeling the loofah from one end to the other. Because it’s slippery and slimy, it helps to have gloves on.
- Make sure to peel off all of it, because any that’s left over will turn brown and grow mold.
- Take off the slimy, dark brown or black parts that are rotting and throw them away.
- Once the skin is all off, use the hose with the strong spray attachment to give it a good rinse on the inside and outside, getting rid of as much of the slimy sap and seeds as you can. You may need to repeat this step a few times. Discard the seeds as they’re not viable.
- The loofah is a little cleaner now, but it’s still slimy inside and needs to be cleaned really well. You could cut it down the middle and take out the core, but I had other ideas. If not, soak it overnight in water with some eco-friendly detergent.
- The next day, squeeze out as much of the pulp and seeds as you can, then rinse the loofah well under running water and rinse it again.
- To get the loofah back to its original color, you may want to soak it again, this time in a mixture of bleach solution and water. I left mine soaking overnight.
- The next day, run water over the loofah several times to get rid of any leftover seeds and sap. Then, squeeze it all over to get rid of as much of that as you can.
- When the loofah is clean, hang it on a clothes line or leave it out in the sun to dry. Turn it around every so often so that all sides get sun. As it dries out, keep shaking it to get the seeds out. But I haven’t tried this method. You could dry it in a very low oven at 50oC or by putting it in front of a fan.
- The loofah is ready to use once it’s completely dry and all the seeds have been taken out.
Here’s the end result. I’m very pleased I was able to salvage some of what I have spent months growing and nurturing.

The process of drying a green, ripe and in this case rotting loofah takes time but if you’ve invested months growing the fruit on the vine, it’s well worth a few extra days’ work.
