One week after planting leaves look to be drying.
Care for Bottle Brush
Leaves drying one week after planting is not a good sign. Handling and planting technique are important, but the most vital is adequate water at the time of planting, and a good water management program to follow.
If you think that the soil root ball and soil backfill in the planting hole may not have been soaked thoroughly at the time of planting, then try this. Poke a running water hose end down into the loose soil backfill around the outside of the root ball. Use a stick to poke straight down in multiple spots and try to settle the soil and fill any air pockets that might have developed in the backfill. Follow up with deep watering a couple of times a week. Give it a month to respond with new growth. If it continues to dry and die back then it may be lost.
