Gardening on Concrete With Raised Beds and Patio

Things to keep in mind when installing raised beds on concrete or pavement: Concrete is alkaline. Over time, this may affect the soil in your raised beds. Test periodically with pH meter and adjust as required. Raised beds built on dark pavement will usually have higher moisture needs than those built on a lawn or natural substrate.
