Q.Newly planted Nectarine Tree slowly dying
I planted a young nectarine tree about a month ago. Now, the leaves are wilting and beginning to drop and I noticed that many of the little branches are drying up and turning a reddish brown. It had just started growing some fruit but now those are dry and hard. I’ve been trying to research the problem but so far I haven’t found anything that matches the symptoms I’m seeing in this tree. Please Help!

Make sure you have planted your new tree properly.
Water is key for new trees; daily for the first 2 weeks.
