July 3 - I forgot to vent and shade a greenhouse before leaving home for the day, and according to my temperature sensor, it was over 120 degrees Fahrenheit for a long period of time. Many of the cuttings I was trying to root got sunburned and severely dehydrated.

July 5 - Trying to salvage what I can, I performed a graft of this cutting (1st time ever ). It's been 3 days since the procedure, and the tips have noticeably browned and withered. The stem is still firm, and I was wondering what you guys thought would be the best course of action to improve its chances of survival. Thanks!

Looks good. Leave the stems on. Wrap the graft with moss and cover the graft with clear plastic. Keep moss moistened. I usually use duct tape to keep the moisture inside the plastic . Moist not wet is key.

Another method would be to put the pot on a saucer of rocks and add water. Then cover the whole plant in clear plastic like a small greenhouse to help retain moisture . Open the plastic enclosure during day if water beads form on plastic to air dry.

Keep in a temp controlled area in a shaded area inside. It may take over a month to 6 weeks to see progress . Open the enclosed area around the graft carefully to check for seal around graft.

I have grafted several trees and shrubs using the moss process . Especially in hot summers it's important to keep the graft moist not wet. Check daily for excess moisture or add a small fan to control the moisture build up. When the graft has grown and sealed remove the moss. Keep in protected area and harden off before placing out in hot sun and temps.

Do you happen to have a picture of what it's supposed to look like? Otherwise I'll try to do my own research. My greenhouse is essentially a clear plastic enclosure, but vented and shaded, it still reaches over 100 degrees Fahrenheit. I actually bought a portable humidifier, so humidity in the greenhouse shouldn't be a problem, but keeping temps down might prove difficult. Thanks for the reassurance and suggestions!
