Planting in mulch or putting plants 鈥渙n hold鈥 in mulch does work for a short time. It works to keep roots cool. However, it’s best for annuals or plants that don’t need to survive a long blooming season. Plants are unable to draw important nutrients from the soil. And the plants will require water frequently, as moisture drains through mulch very quickly. So, if you put the plants in pots of mulch, it’s not a long-term solution. We’re not sure what you mean by putting mulch in between two pots. Mulch should help cool the pots if you place between the two pots. However, I’m not sure it does much more than that.
