“I have a problem with my EarthBoxes (self-watering containers) staying too wet. I need better drainage. Which of your products would you suggest I try? Thanks!” Question from Larry of Mooresville, Indiana
Answer: There are several things that you can do to fix this problem. First, remove all of the old potting mix from the boxes, and make sure that the self-watering system and holes are free and clear. It is not uncommon for them to get plugged up with soil and roots over time. Next, choose a very fast-draining potting mix. I suggest using Black Gold Natural & Organic Potting Mix and boosting its drainage with added Black Gold Perlite. Consider four parts potting mix to one part perlite. Finally, be sure not to overwater the boxes. Allow them to dry somewhat between watering. I hope that these tips help!
