Recent Question from Gardeners
Question
Jacaranda tree
I have a recently planted jacaranda tree with a central trunk...it doesnt seem to be branching out its about 10 feet tall now. Should I pinch back the top to force branching?
Answer
Pinching back the tips of the canopy will encourage more lateral growth however it sounds like the tree has only been planted for a short period of time and may still be adapting to its new location. You may want to give the Jacaranda tree sometime to adapt. If you do choose to pinch back the tips or remove the most advantageous limbs at the top of the canopy do not top the tree. Topping trees leads to insect, pathogen and structural problems that may not be correctable.
