I have about 20 solid white brick that look like ceramic. I am going to make a small square foot or rather 8 inch square bed just for my peppers. This will be interesting . I will line up the the brick in a row about 8 inches appart and plant the peppers every 8 to 10 inches appart. The brick will be laying flat so the full surface reflecs light and adds heat to the area!The reflected light and extra heat should make the peppers grow fast! I guess you could paint brick white! These brick are very heavy about twice the weight of a regular brick!
+++My dad use to put lime on the surface of the garden or around the base of trees near the garden. I am wondering if the white did help the plants grow since his garden was always so nice and healthy!
