Pruning

Pruning is the removal of branches or roots from a plant. This is done to change the plant’s shape, remove dead or diseased parts, or to improve the quality or quantity of flower and fruit. The natural form of a plant changes as you prune it.

The basic tools are:

SecateursSecateurs.

There are several types of secateurs available. All are used for pruning small twigs and branches up to 2 cm thick on plants such as roses, shrubs, grapes and fruit trees.

 
Hedge clippersHedge clippers.

Hedge clippers are used to trim shelter trees and hedges. Power shears can also be used.

 
LoppersLoppers.

Loppers are really strong secateurs with long handles, which give extra leverage for cutting thicker branches up to about 4 cm in diameter.

 
Pruning sawPruning saw.

Pruning saws are used for cutting branches larger than 4 cm in diameter.
