A healing chamber is necessary to protect the newly grafted plants while they are healing. For one or two plants, simply have a large plastic bag handy to place over each plant after the grafting occurs.[11] For a larger number of plants, and a better chance of survival, build or purchase a large wooden or PVC frame, then draping it fully with polyethylene sheeting. Have a tarp or opaque shade cloth ready to block most sunlight from entering the chamber during the first stage of healing.[12] Place a bench in the chamber to hold your plants.
