The main effects of pruning on pistachio tree and its pistachio shell advantages and disadvantages are summarized as follows: Basically, pruning a pistachio tree, like other fruit trees, has a shortening effect on the tree. If the tree is not pruned, it will grow more naturally and the crown of the tree will be more dense and full. The effect of pruning a pistachio tree is not the same as that of other fruit trees because the non-productive lateral buds in this tree are less than the flowering buds, so its vegetative shoots will be less for next year. Summer pruning, by reducing the hydrocarbon content in the branches and leaves, practically shortens the longitudinal growth and increases the transverse growth of the tree. Decreasing the number of leaves due to pruning causes a lack of nutrients in the roots and thus reduces the general growth and development of the tree. Pruning, although it stimulates the growth of part of the tree organs, but in general reduces the strength and overall growth of the tree. Winter pruning The exact role of summer pruning slows down the growth of the tree.
