How to Grow Watermelon in the GreenStalk

by GreenStalk Grower on June 25, 2015 3 comments

Originally, we classified growing watermelon under our 2015 “Experiments” because we honestly weren’t sure how they would grow using the GreenStalk gardening system. We started our testing growing sugar baby watermelon by seed. Here’s how we did it:

This was our first sighting. How cute! At this stage, they were very low maintenance. No staking required. They just vined all around the GreenStalk.

We knew we were on to something when we saw about 8 of these baby watermelons! At this stage we began looking for ways to start supporting them as they grow larger.

We came up with a support system that includes a garden staple, twine, and nylon netting. It has held up great and was inexpensive and easy to put together.

Here’s how it works:

Start with a square piece of netting material.

Tie two pieces of twine on opposite sides of the netting to create loops.

Place a stake or garden staple in a tier above the watermelon you wish to support.

Lastly, carefully wrap the netting around the watermelon and place the twine loops on the upper stake or garden staple.

    Just like most of these blogs, There are no details. ie. did you plant them in the upper or lower pockets, did you grow 1 or 2 or 3 per pocket, how far did the plants sprawl on the ground etc. The little net thingies are great and very important to know, don’t get me wrong. How about some planting charts, I started with one planter, and am getting another for my birthday, so with two planters I would like to combine the different veggies to have a good dinner salad almost daily as well as some cooked greens, I have my strawberries, corn, tomato’s planted traditionally, as well as collards because they grow so big, I will use one planter just for beans for eating and canning, but, most of us can’t afford more than one planter, so we have a need to know how to grow a variety of plants in one tower.

    Hi Jo,

    Thanks for the feedback. We are always looking to write blogs to give specific details on how/what we grow in our GreenStalks to give our customers ideas on what they can grow at home. To answer your questions:

    We planted in the upper pockets and planted squash below. We didn’t mention it, because you can do either! We always recommend that you plant your largest plant on the bottom so it doesn’t shade the ones below, but if you’re growing all large plants (like we did here) it just depends on personal preference. Since watermelon is a vining plant, we knew we would have to create a support system for the watermelon and that’s a down side to growing in the upper portion of the GreenStalk (but it sure does look pretty!). Otherwise, if you grow a vining plant in the bottom of the GreenStalk, you would just need to prepare for vines growing out on the ground. With our cucumbers, they spread about 2 feet around the GreenStalk. But that will change with plant and variety.

    Stay tuned for more info on planting multiple plants in a GreenStalk. I have a couple of GreenStalks at my house and I grow something different in each pocket. I will be doing a post soon 🙂 Thanks for reading, Happy Gardening!

    Oops! Almost forgot, we planted every other pocket just to test out. You may be able to do 1 per pocket depending on the variety.
