Hi, I saw some Weeping Cherry trees for sale at our local Lowe's Home Improvement Store. They are about 5 feet tall, and in 7 gallon containers (maybe larger). It is now mid-September and we are in Growth Zone 7a (Southern New Jersey) I have a great spot for it, where it gets full sun all day long, and I think would be a beautiful addition to the side yard. My question- is mid-September too late to plant? Our temperatures are now in the 70's to 80's by day, and 50's -60's by night. Thanks for any suggestions!
