This advice is for turf types sold by Associated Turf.
Watering
Tip #1: It is important to water really deeply and less frequently.
Watering once a week in summer is usually enough, provided the water is a deep one. It’s best to saturate the lawn using a sprinkler for about an hour or more. This will ensure the water gets in deep and it will encourage the roots to follow the water down and grow deeper, making your lawn more drought tolerant.
After a lawn has been in a few years and it becomes very drought tolerant, you may be able to water heavily every two weeks in summer. If it rains, take that into account and water less. In the cooler months lawns rarely need watering if rain occurs occasionally.
A lawn will actually tell you when it needs watering. The leaves will start to wilt slightly. If this happens it is time to water. It is a little more important with Buffalo varieties to not let it thin out due to long periods of drought. Try not to leave Buffalo brown from drought stress for more than a week if possible.
Fertilsing your Lawn
Research shows that autumn is the most important time to fertilise your lawn. Fertilising in spring for most lawn types is not enough. The minimum fertiliser needed by a lawn is twice per year, but that is only if you use a slow release.
Summer fertilising is also important, but in summer it is very important not to use a fertiliser high in nitrogen Too much nitrogen in summer makes the leaves of turf grow really fast, and worse it can make it more susceptible to some diseases.
