Are these the same tree
I purchased these 3 hornbeams but the one on the right seems to be growing differently. Can you tell if they’re the same?
I can't compare leaves or bark from these images; but the first image shows them appearing very much the same.
It looks like you have some differences in growth pattern since their planting.
This could be due to moisture levels, sunlight conditions or nutrient levels.
American hornbeam is sensitive to drought, heat, and soil compaction. Plant it where soil moisture can be maintained with mulching and supplemental irrigation during summer dry periods.
I found this info; 'Landscape trees and shrubs should not be fertilized unless a soil test indicates a need. Correct soil pH, if necessary, by amending the backfill soil. No nitrogen fertilizer should be added at planting or during the first growing season.'
Your County Extension Office can help with a soil test.
