Though expensive


Interesting item

I purchased two of these to use in two large 2 feet wide planter pots. I wish I purchased more-- the roll may have been better for my needs. Since I just put them in the pot with soil covering them just last week, I can't really give an assessment of whether or not they work well-- but it was easier and a lot lighter than using gravel/rocks.More > < Less


I'm very glad I decided to try it!

No more smashing up old pots or hunting in the garden for rocks for drainage. This drainage material really works! It's neat and handy. Just keep some around, and you're always ready to re-pot. I'm very glad I decided to try it.More > < Less


Smart idea

This product is so easy to use & saves time by not having to scoop lots of soil into pots, & the best feature is that it is so lightweight & I don't need to lug such heavy flowerpots. Also doesn't interfere with root growth & allows for ventilation.More > < Less

Better Than Rocks - Planter Drainage Material

About Better Than Rocks

This gardener's tool rocks

Container gardens are magical. Whether they’re made up of colorful flowers or stunning foliage, they can turn an ordinary rooftop into an urban paradise, or transform a bare front porch into an inviting retreat. Smart gardeners know that the key to keeping plants healthy is good drainage. Traditionally this means lining the bottom of planters with rocks, which makes the containers heavy and unwieldy and can quickly turn a green thumb into a pain in the back.

Enter John and Sarah Hoggatt, who discovered that the recycled plastic mesh John’s brother-in-law patented as a building material could double as lightweight, eco-friendly drainage at the bottom of a flower pot. Better Than Rocks works just like rocks do, allowing water to flow freely, yet trapping needed moisture inside the pot. Presto! Pots are pounds lighter, making it easy to rotate them according to your plants’ sunshine needs. The result: a lush, long lasting garden you can enjoy all summer long and no more back pain. As a bonus, Better Than Rocks is also conveniently reusable. Simply shake out, hose off, and you’re ready for the next planting.
