Areas with warm or hot summer nights require grasses that are drought and heat tolerant.
This popular type is a strong creeping and spreading grass but it sometimes tends to develop thatchy spots. It is durable and pest-resistant but it is meant only for sunny locations. In shade, Bermuda grass becomes thin and leggy.
This grass is slow to become established. It requires 3 to 4 years in most areas and weeds can take over before it makes a lawn. Deep-rooted and drought-tolerant, it becomes dormant during cold weather and tends to stay brown longer than other grasses.
This grass has a very coarse texture and is heat-tolerant. It spreads rapidly and can creep into nearby lawns and flower beds.
These are slow to establish themselves but are especially tolerant of wear and drought.
Not all parts of your yard are well suited for grass. Areas under large trees, slopes, shady spots north of buildings and baked areas next to sidewalks or drives would be more attractive and useful hardscape feature.
