There are a few factors that affect how much water your lawn needs. Being familiar with these factors can help you adjust your watering practice so that you can give your lawn the optimum amount of water it needs.
1. The soil condition
Different soil has different water holding capacities. The different soil types also absorb water and dry out at different rate.
For sandy soil, it is not able to retain much water but water can penetrate the soil quickly to reach the roots. As such, you have to water your lawn more frequently.
On the other hand, clay soil holds tightly to water but it is poorly aerated. In this case, the water takes a long time to reach the roots. Therefore you have to apply more water slowly and evenly so that the soil has time to absorb it and let the water reach the roots. In general, lawns growing in clay soil do not need to be water frequently.
Loamy soil falls between very sandy and heavy clay soils. It is adequately aerated and has reasonable water holding capacity. Water can reach the roots fairly quickly too.
Most lawns are made up of more than one type of soil and thus it is advisable to pay attention to how your lawn soil is absorbing water and adjust accordingly.
2. The weather and climate
In general, the hotter the weather, the more water your lawn needs. Thus you may have to water your lawn more often in the summer seasons than the spring seasons. The same rule applies if you live in an area that is windy and low in humidity.
You can cut down the frequency of water if you live in an area with cooler temperatures and low wind. If the humidity is high or the sky is cloudy most of the time, you also do not have to water your lawn too often.
If you live in an area with a lot of rain, you probably can get away without watering your lawn.
3. Amount of shade available
A flat lawn that is fully exposed to sunlight will require more water. If there are trees in your lawn, you may water the lawn less often. However, the areas near the trees may require more water, as the tree roots will suck the ground dry very quickly.
4. The type of grass in your lawn
There are two broad classifications of grasses – warm-season and cool-season. Warm-season grasses can adapt to hot weather very well and generally require less water. An example will be Bermuda grass. Cool-season grasses such as Kentucky bluegrass usually require less water.
However, there are some cool-season grasses can look bad from less than optimum watering and there are warm-season grass which can survive on little water. Thus it is advisable to find out the exact type of grass that your lawn has and gain a deeper understanding of its characteristics.
5. Cultural practice
If your lawn is mowed short, then you need to water it more often. If you apply more fertilizers to your lawn, the grasses will also grow faster. This means that more water is required to facilitate the growth.
The amount of water that your lawn need is usually affected by a combination of two or more of the factors mentioned above. You need to observe how your lawn reacts to your watering practice. By understanding the different factors that affect your lawn and observing your lawn’s reaction, you will be able to find out the optimum amount of water that your lawn needs to grow healthily.
