Pruning Mango : Season 2

Our Imampasand and Alphonso mangoes turned 2 years this October. Most of them have already been pruned twice. With the onset of this years monsoons, the vegetative growth was accelerated and it was time to control the foliage and shape the canopy. The right canopy makes a difference in the trees ability to flower and later during fruiting during later years.

There are conflicting theories on whether to prune above or below the whorl, which is the inter-modal ring found in the branches. In traditional cultivation, the cut is made above the whorl to attain maximum shoots. In UHD, since the tree structure is smaller, it is important to control the shoots to avoid overcrowding. By cutting below the whorl, you would typically get 2-3 shoots which is ideal for UHD form of cultivation.



It is important that you allow enough sunlight to penetrate the foliage which involves pruning secondary branches present in the center of the plant. These branches will not bear fruit and you want to decrease non productive foliage as much as possible so that the necessary nutrition goes to the productive branches. Tertiary branches are typically found on the side of the canopy and are fruit bearing. It is imperative tertiary and above branches are not too long to avoid sagging of fruits and branches due to weight.



Before Pruning, with multiple secondary foliage.

After pruning, with healthy tertiary branches which will grow into multiple fruit bearing branches

Alphonso and Imampasand are both premium Mango varieties with wonderful texture and fragrance. With all the desirable qualities, these varieties do have a constraint since they are shy bearers. Not only is the annual fruit yield significantly less than Baiganphalli or Dusheri varieties but significant fruit yielding in these premium varieties often occurs in alternate year. Producers planning new orchards should take the expected yields into account and consider the right mix of heavy and shy fruit bearers.

  2. Good growth. Are you spraying any growth regulators? Also after prunning are you applying any fungicide on the cut? How often do you deweed?

    1. No, we are not using any promoters. We apply Copper oxychloride 2g/L. Just a spray over the cut. Deweeding is done once in 2-4 months depending on the growth.
