Hello Jerry,

Thank you for your question regarding your peach tree. As you may already know, flowers appear before the leaves. Did you notice a standard amount of flowers this year?

I wouldn't be too concerned yet. Leaves will generally appear on the newer scions (the newer woody growth). I see lots of new growth, just not new leaves yet. The leaves that have appeared look normal from the photos you sent. If you are able to send a photo of the base of the tree where it meets the ground and a closeup photo of a leaf, that would be helpful. Also how many hours of sun does the tree get?

Thank you,

Hello Jerry,

Thank you for the additional photos of the canker on the trunk. That is an important symptom to notice. Cankers like that can often be a symptom of bacterial infection. The high relative humidity and cooler temperatures can lead to infections like this taking off. More information on causes and management can be found in this fact sheet: https://ipm.ucanr.edu/agriculture/peach/bacterial-canker/

Unfortunately, management of bacterial cankers on peach trunks can be difficult and is not always successful. You may want to have an ISA certified arborist come look at the tree if you want to move forward with any of the treatment strategies in the fact sheet. I'm very sorry that I don't have better news to share. 

Feel free to reach out with any additional questions.

Thanks,
