We  wanted to help raise awareness of the fact that rocks, gravel, bark and packing peanuts can actually hinder rather than aid drainage in pots and containers. This can lead to root-rot and can actually end up killing plants and flowers. That’s why Drain Smart discs are so useful. They not only help better drainage through their proprietary technology, but they also stop soil and dirt leaking out of the drainage hole. We have put together a guide of useful articles and academic research into the subject matter. We hope you enjoy reading them.

Just say “NO!” to inferior drainage materials that can hinder rather than help container drainage! Use Drain Smart discs to promote better, uniform drainage.
