Gardenia growing in Middle East
I live in the Middle East, and I'm trying gardenias in my garden. I'm new to this and I'd like to know if is possible to transplant the gardenia now (38 to 40 Celsius at noon, 27 to 30 at night) or shall I wait until the temp is lower? Additionally, I'd like to know if is a good idea to place some stones below it to improve the draining after spraying some water. Thanks in advance!
