Pruning is one of the most important cultural practice in orchards. It could be manual or with a pruning machine. After pruning it could be sprayed with broad-spectrum fungicide.
Time of pruning
After harvesting of fruits, April is the ideal month for pruning.
When to start pruning
Plant should be trained and pruned from first year of plantation.
Degree of pruning
Guava should be medium pruning
General rules for pruning
- Prune all dead and diseased branches
- Pruning severity will increase with the increase in planting density of orchard
- Cut the dead/diseased wood in such a manner that its one-inch green portion must be cut so that
- Cut the branches above the buds, so it may not be injured.
Canopy Management Prune the shoots going inside the canopy while keep shoots coming outwards so that canopy gains maximum size having space inside. Prune the fruit plant so that maximum light and air circulation reach in every portion of the plant. This is called canopy management.
- Prune the plant with sharp pruning shear/scissor or secateurs so that braches may not damage.
- Sterilize the shear/scissor or secateurs with alcohol so that it may not spread diseases.
- No branch should touch the ground.
- Do not prune during intense high temperature (May, June, July) as it may cause wilting
- Do not prune during rainy days which may lead to fungal attacks.
Height of plant
Height of plant should be about height of man. So that all operations i.e. spray, trimming, picking of would be easy.
Pruning too severe leads to dieback of the plant because during summer plant heat up and does not find enough leaves for transpiration (cooling effect). Plant heat up and die.
Benefits of pruning
- Plant age increase.
- Plant get high yield.
- Fruit quality will be good.
- Plant will be less susceptible to diseases and insect pest.
- It will make plant frame work strong.
If a plant bears a lot of flowers from the same point remove some flowers so that size and quality of other fruits may not be affected. But more than 50% of de-blossoming causes low yield.
