Ginkgo freeze troubles #749934

Asked May 14, 2021, 2:02 PM EDT

Hello, I planted a 5 ft ginkgo about 5 years ago in my tree lawn...I believe cultivar autumn gold. Did lots of research and they were recommended by city of Denver and Various Colorado tree resources I follow. It has been a bit of a disappointment tho. It’s never really grown much and doesn’t really like our fall and spring temp swings. It’s very much alive but I think an early freeze in fall 2019 or maybe late freeze last year got the tips of most branches. I know one year It leafed and froze and then releafed late summer. But ever since leaf in spring of 2020 it has only really leafed toward central areas of the tree and the tips sort of still look frozen and dead. It’s hard to tell on a gingko of course what’s alive or dead. But I gave the tips all last year to leaf and they never did. They appear to not be leafing this year either. Most of the inner growth looks fairly healthy. I saw one fairly large (30 ft) one last summer that looked similar. I guess I just hoped mine would eventually recover. I’m fine pruning off what’s not leafed out but is this never going to be a good tree for Colorado's springs and falls? I planted it becuase they are known to be strong trees. I have never seen fall color on it...leaves always freeze green. And I don’t want a tree that I’ll forever be fighting dead wood on from freezes. Should I cut my losses? Will it eventually look better as it matures?

Many factors could account for your ginko's failure to thrive. We would need much more information to diagnose the problem. It is possible that it was not planted correctly, there are many environmental and weather considerations, and pruning may have removed some living tissue. I noticed in my research that ginkos are extremely slow-growing, so it is normal that it appears to not grow for several years. 

Any time we receive questions about trees, we recommend contacting a tree company that has a certified arborist on staff to evaluate the situation.

See https://isarmc.org/Certification for information about finding a tree company with certified arborist on staff.

I am sorry I could not find anything more specific about your tree.
