world's longest dormancy? was created by Smilkste

Hi all,

Our Chinese Elm was severely unwatered 5 months ago, lost all leaves and looked grim. However, trunk and branch scraping revealed underlying green, so we've continued to water and periodically scrape to check for life. Still zero budding or regrowth over 5 months, but still green when scraped!! Is it possible that it has simply gone into dormant mode and stayed there? Any other ideas? If dormant, other than prolonged cold, is there anything that might stimulate regrowth? Has anyone out there seen one go this long without coming back or dying? Thanks!!

If you are in the northern hemisphere and the tree has been leafless for 5 months of spring and summer I would assume it is dead.

I’ve heard of trees staying dormant all season, and coming back the following year.

I have a maple that just sprouted out about 2 weeks ago (USA) after staying dormant since last fall. It’s weird, but it can happen. Make sure it has the right amount of water, and maybe some fertilizer every once in a while.

Maybe look at make sure new buds aren’t getting eaten by pests.

Leafless decidious temperate trees in summer is not a sign of dormancy.

5 months ago was the end of dormancy, not the start of it.

Actually in climates with very hot summers there is a summer dormancy period. I have a dogwood in the yard that loses its leaves during August some years. This year has been crazy with rain and cool, but usually there are weeks of >35C and the trees don't even try to function.

I don't think the tree is is dormant. The summer dormancy here is usually a couple of weeks and then leaves start again.
