Related Question Answers

Will Styrofoam kill plants?

The answer: Not really. In fact, if you are using a pot with little to no drainage, adding Styrofoam packing peanuts could do more harm than good. Deep plant roots can grow into the foam material, and without sufficient drainage, they can become waterlogged and rot or die.

Should I drill holes in my planters?

Potted plants need holes in their containers to allow drainage, which supports plant growth. Without an escape route, excess water saturates the soil of plants, preventing their roots from receiving adequate air. With the correct drill bit for the container's material, you can create proper drainage holes easily.

Is Styrofoam harmful to plants?

What are the white pellets in potting soil?

Perlite Explained Perlite used in soil resembles tiny white plastic foam balls, but it's actually a naturally occurring volcanic glass.

Does concrete stick to foam?

How do you cover styrofoam on concrete?
