The water-holding capacity of the growing medium determines how often and how much to irrigate.
Taken at face value, irrigation appears to be a simple operation, merely ‘watering plants’. But if you get it wrong, crop growth will be hampered and the quality of the crop compromised.
Frequent watering will prevent plants drying out between waterings. The irrigation cycle should, however, also be long enough to ensure that the medium drains out adequately each time.
If you under-irrigate, the plants will wilt and turn dark green to blue-green. The stomata will close to reduce moisture loss through transpiration, and this will increase the plant’s internal temperature, as cooling by evaporation cannot take place. If it lasts for a long time, yield will be reduced.
