I have several large containers with dirt left over from plants that didn't make it. My question -- can I reuse this soil for new plants? If so, is there anything special I should to do prep and/or repair the soil? It seems rather dried up, although weeds seem to be thriving in the containers. Thanks in advance!
the plants in it before didn't die of some disease you can reuse the soil.
First loosen the soil, packed down soil is not good in a container. I would mix in some compost or depending on the container size, a small bag of Miracle Gro potting soil.
