An efficient watering program, combined with a moderate level of fertilizing and proper mowing height, will produce a superior lawn. Not only will your lawn look good, but it will also be able to withstand the stresses it encounters. Landscape irrigation is often necessary in Florida's hot climate. Daily temperatures can be over 90 o F half the year, which causes large water losses from soils and plants. Rainfall averages 60 inches per year, but half the amount falls from June through September, often in sporadic large rainstorms.
Less rainfall occurs during the winter and spring.
Another reason for irrigation is that Florida's sandy soils do not hold much water. Deciding how water is to be applied. The most efficient way to irrigate is to apply water when plants begin to show signs of stress from lack of water. Prolonged dry periods of high temperatures, strong winds, and low relative humidity cause these symptoms. During such times plants wilt, even though water may be in the soil, because they are losing water faster than it is absorbed through root systems.
