Irrigation (Gardens) Warnborough College

Overview

This Irrigation (Gardens) course from Warnborough College focuses on irrigation for parks, home gardens, and other ornamental horticulture areas.

Key facts

• Water is essential to healthy plant growth. It is often the major limitation to a plant’s productivity. Irrigation may enable plants or turf to be grown in a dry climate where it would not otherwise be possible. 

• It may also supplement the existing rainfall and improve growth rates by extending the growth period of the plant. 
• It may ensure that there is adequate moisture during critical periods when a plant is growing most rapidly. Irrigation at appropriate times may also improve the quality of turf or the general health of garden plants. 

• The value of irrigation can vary greatly from year to year depending on the distribution of rainfall during the growth season.
