Watering (Drought stress & shallow roots)
Water is essential to all lawns whether that be a domestic household lawn or a manicured bowling green or sports pitch. But too much or too little can harm them. Water your lawn too much wastes a precious resource and sets up the right conditions for disease, weeds, moss & worm casts. Frequent, light watering sets your lawn up for trouble during hot and dry weather due to encouraging shallow roots.
You want deep, infrequent watering that gets down into the root zone. That means at least half an inch twice a week, or one inch a week as a general rule of thumb.
Watering early in the morning is most preferred as this provides the turf adequate time to absorb sufficient moisture and yet leaves adequate time for the turf to dry out during the day, therefore not creating a damp environment which encourages mildew, fungal growth such as Red Thread, moss and weeds.
Always remember to water your lawn evenly ensuring each area receives the same amount of time.
