Self-Irrigating Gutter Update

We’ll get back to our thoughts on responses to the Three Headed Hydra of Doom tomorrow, but for today we’re going to take a quick break for a practical post: Self-Irrigating Strawberries!

This spring I built a self-irrigating gutter (SIG) using two gutters based on a video by Larry Hall. You can see my original post about this project here. Essentially, it is a gutter filled with potting mix, sitting on top of another gutter filled with water. Every eight inches there is a 3 inch perforated pot filled with potting mix that hangs down into the water filled gutter. For mulch I used re-purposed billboard vinyl scavenged from a dumpster by my neighbor Ray.

The SIG works, but there have been a few problems. My strawberries, I believe, have a fungal disease called red stele (Phytophthora fragariae) which came either from the soil that came with the starts or from the planting mix I used. If I want to grow strawberries again I’m going to have to thoroughly disinfect the gutters.

The SIG is hooked up to a 55 gallon rain barrel. Unfortunately the lower gutter leaked around 50 gallons of stored rainwater down into the garage below (our house is on a hill and the garage is at street level). To prevent this problem in the future I put a manual irrigation timer on the barrel so that if there is a leak, I won’t lose all the water at once.

If I were to do this project again, I’d also use a refinement that Larry Hall just posted in the video above. This improvement on the design replaces the lower gutter with a 4-inch drain pipe. The drain pipe is easier to keep water-tight. And instead of using a gutter filled with soil I might use a series of pots (an idea that’s also in the video)–gutters are too shallow for most plants.

Despite the problems, I would call the project a success. In fact, I may expand my gutter system out onto the rest of the garage roo.

  1. An added plus to the video was the link to the Texas Preppers greenhouse (bottom right). I love the ease of construction and rigidity of his design.

  2. Pretty neat, the cool thing about doing it in a pipe is maybe you can make interesting shapes by bending the PVC. I guess it has to be level though right for the water?

    I’m thinking Strawberry Hentai Gazebo……doomers gotta have a place to philosophize and whatnot.

    • Get Claudio working on this pronto. And get out the respirator, I’m seeing some fiberglass work in our future.
