Trimming

Trimming, or pruning, is the physical act of removing the unwanted parts of a plant such dead leaves, crossed branches, and diseased parts. When pruning is done, it increases the aesthetics of a plant, helps the plant grow more, and helps the plant attain good shaping. Pruning is also used to train a plant, restrict growth if required, increase the quality of fruit.

Other benefits of pruning include:

  • Increased airflow
  • Increased flowering
  • Lessened disease spread
  • Higher growth or development

When to trim, or how many times to trim, depends on the plant variety and the particular growth cycle of a given plant. It is crucial for a cultivator to get advice from horticulturalists or expert landscapers before pruning.

The two basic cuts in trimming are:

  • Heading back cut: From back to an intermediary
  • Thinning out cut: From back to point of origin
