We purchased this tree at the Denver Botanic Gardens in May 2023 and planted it in our backyard. The tree trunk has a diameter of 1 1/2 inches. It grew well last year and it was the first of our trees/plants to produce blooms and leaves this spring in April. Then the final snow of the season and freezing temperatures hit and the opening buds of the chokecherry shriveled with frostbite (?). Since then there is no more budding/leafing activity. Will the tree eventually put out more buds? Is there anything we should do to encourage this? Has the tree actually died? Any advice you can give us would be appreciated.
