Planted a Japanese maple cultivar near a shrub dogwood (Cornus racemosa) for wind protection and summer shade. I am in South central Kansas so not the ideal climate and hoped to create a micro climate.
In its third year I have noticed that all the maple branches closest to the dogwood are gone, all the growth is away from it. See the pictures.
Is this too much shade? Maybe an Allelopathic thing going on? What are your thoughts?

Look up “Japanese Maple winter die back”, most common reason is temperature fluctuations.
Perhaps this unknown cultivar is growing towards the light, or the prevailing winter winds are from the direction of the dieback, or some other reason having to to with environmental factors, but *Cornus* are not allelopathic.
