Q.Weeping Cherry
Hello! So I planted it about 3 weeks ago, and the leaves have all gotten brown and dried up. Do I remove them? Do I trim the branches as well? Is it salvageable? Thank you for your assistance!
Watering a newly planted tree is very important.
Make sure the soil and planting area is well draining.
Daily water for 2 weeks, then a bit less; but regular irrigation throughout the growing season.
3 to 4 inches of hardwood mulch will help with moisture control.
If the branches snap and break off, they have died.
This article will refresh you on the care requirements.

Most reputable garden centers will guarantee a new tree for 1 year, so if it does not come back next year, you may be able to have it replaced.
