Growing Luffa - It's a Green Thing

Spring is a busy time of year and we all do our best to pitch in to keep the farm moving forward. Things like sheep sheering, lambing season in addition to the garden and crop planting all come full circle.

This year our large crop will be Luffa and we decided to scale back planting so we could test an idea using buckets.

Luffa is an exfoliating sponge, it’s an annual plant that grows on a vine and has a 200 day growing season.

What you’ll need to begin

After researching this plant for months we decided it was a good fit for our climate because we do have a rather long growing season.

The first year we learned a lot and decided to move forward by adding another field and wow was that ever intense growing because it required a lot of our time.

Luffa plants require a sturdy structure to grow on because the pods are heavy and grow from a vine.  Use a sturdy fence or build something like we did to test grow Luffa on a small scale.

For seed purchases keep it simple that first year and purchase online unless you can find seeds already native to your area.

The first year we learned a lot and decided to move forward by adding another structure in a half acre field; this was intense.

  • Build a structure from landscaping timbers and 2 x 4’s


Learning more

The first thing I learned in our second season was farming on a large scale is hard work.

Growing thousands of plants at one time and individually attaching each vine to the netting was more than I could handle.

I spent most of my mornings from May- June attaching vines with string to netting and it wasn’t fun, it felt overwhelming like it would never end.

It definitely went faster when my husband was able to help after he came home from work.  Needless to say we learned a lot that second year and decided we needed to change things.

We’re in our third season and we went back to our test field.  We had this idea to plant in buckets instead of directly in the ground.

The point of the buckets was to decrease labor, this will keep us from having to till the ground and allow us to focus on each plant as luffa can grow out of control very quickly.

The root system on these plants is pretty compact and requires a lot of water so we’re hoping the buckets will help hold the moisture; this is why some are under ground.

Things to Know Before Growing Luffa

  • You need a strong structure for them to grow on.
  • Annual with a 200 day growing season
  • Thrives in warm, humid wet climates, 70 – 100+ degree temperatures.
  • Transplanting is temperature tricky – We recommend direct seed only.
  • Soil must be well prepared before planting.
  • Plants will turn black after the first frost/freeze.
  • Luffa vines attract Fire Ants – this detours other bad bugs.
  • The Bees love it and every variety will arrive to pollinate.
  • This plant requires a lot of water.
  • Harvesting is intense with a large crop.
  • You replant from seed every year.
  • Luffa’s should grow hanging free to harvest nice healthy sponges.
  • Don’t press on Luffa when it’s growing – you’ll bruise the sponge.
  • Harvesting begins when the outer skin turns yellow to brown and light in weight.
  • You can eat Luffa in the early stages under 6 inches.

It will be interesting to see how this test crop produces,  this experiment could change how we do things in the future or if we even decide to keep growing this crop.

What I’ve learned about farming over the years is that there’s always a journey of learning and discovery.

    Thank you for sharing that! I have always wanted to grow these but when we moved to Utah (no way I'm getting a 200 day growing season!) I gave up on the idea. We're moving to Missouri now and I'm hopeful my climate will support their growth since its Southern Missouri to which we're headed. We'll see!
    Have I invited you to pin to my Children's Garden/Homesteading board yet? I'm totally pinning this article there but I see a lot of your posts that could be used to inspire the next generation of homesteaders, which is the goal of the board. If you're interested, here's a link; just follow the board and I can send you and invite!

    1. Glad you enjoyed this post. Luffa is a tricky plant to grow but I can't imagine not having luffa in my home. I love it for more than exfoliating. I followed that board would love an invite. THanks for thinking of me and I'm glad you stopped by to share. -Carole

      Luffa is a great skin exfoliator and more: use as a surface-safe, renewable scrubpad for washing dishes, sink, bathtubs, etc. Young luffas can be peeled and diced into soups or stirfries, too.

    3. Yep Luffa is Awesome! You should check out my Farm Website –

    This post has been a learning thing for me as I had not idea what was Luffa not to mention how to grow it. Now thanks to you I have even googled it up and I today I have already learn my little 2 cent's for the day :). And one of the things I found out is that I knew what it was except I had no idea it was called luffa. It's great to have a passion and I can tell what is yours.
    Have a lovely day!!

    1. That's neat! It's an interesting plant to grow but Luffa itself feels wonderful when it's grown naturally. In my 40's with baby soft skin. Thanks for sharing and stopping by! Carole
