It went from wet tropical, to hot, dry desert like conditions in just over a week. Rain has been in the forecast almost every day up till a few weeks ago. With the tropical like conditions, plants grow fast. There is lush growth on all the M. basjoo . It's been so hot here lately, (in the hundreds), with full sun, and no breeze, that the leaves on my M. basjoo are burning. They've been in the same location for many years and this never happened before. Is there anything I should do for them?
