Q.Trees not growing
I have 4 trees, 2 trees are mulberry and not sure the other 2. I planted each pair the same day in different locations. 1 of each in front yard and the other 2, side if house and back yard. The 2 in front are close to a mesquite tree. Is it possible that the mesquite tree is stunting growth of those 2 trees? They look perfect, just dwarfs in front yard and the others at side of house and backyard compared to each of their mates planted elsewhere. They are very short but would look the same if not short. I have heard that mesquite tree roots find water from other plants. Just curious and no one can answer this for me.
Though it is possible that the Mesquite Tree has lots of feeder roots and may effect nearby plantings, I think it is more likely a soil issue or watering.
I would have a soil test performed and find out if you need to amend or change anything in the planting area.
Newly planted trees need daily water for the first 2 weeks, then you can cut back.
