Crab Apple Trees Flowering in November?

You may have noticed that certain varieties of Crab Apple trees are displaying some  minor flowering right now. The below photo was taken October 31st.

The months of September and October were abnormally warm. This warm weather will confuse many flowering trees and shrubs.

Flower buds for the following year always form during the prior season. Ordinarily these buds sit closed on the tree throughout the Fall and Winter waiting on Spring. However, if the Fall season is unseasonably warm and those buds receive above average warmth for an extended period of time, a second flowering can occur.

What this means is that these trees will not flower as fully next Spring and in some rare cases, may not flower at all depending on the variety of tree involved. Even though you may not be seeing this second flowering occurring on your tree at the present time, that does not mean that your tree might not be affected next year.

Even if flower buds fail to open as those shown in the photo, they may have swelled beyond the point that they normally would. If that is the case, it is possible that Winter’s cold temperatures and winds might burn the swollen buds that are not as dense, compact and insulated as they normally would be. Should this occur, the buds will sustain damage and not open next Spring. Only time will tell.

On a better note, we have been driving past clients homes this Fall checking on our fungal treated Crab Apple trees and we hope you are as happy with their condition as we are. We promised our new treatment products for 2017 would produce tremendous results and they obviously have! We are seeing Crabs that are still fully leafed!

Have a wonderful Fall and upcoming Holiday Season.
