You need to water a newly laid lawn two (2) to four (4) times a day for several weeks. The goal of frequent watering is to keep the ground moist until the grass establishes its roots. Afterwards, you can water it 2 to 3 times a week, depending on the weather. Make sure that your established lawn gets about 15mm of water each week.

Watering Your New Instant Lawn

For a newly laid instant lawn, you need to keep on top of watering to prevent it from drying out.

First two weeks

For the first two weeks, you need to water it about two (2) to four (4) times a day. It will depend on the climate and weather in your area.

If you lay your instant lawn during colder months, twice a day may be enough.

If you water four times a day, water during:

  1. Early morning
  2. Mid-morning
  3. Mid-afternoon
  4. Early evening

If you water two times a day, water during:

  1. Early morning
  2. Mid- to late afternoon

After two weeks

After two weeks, you can water once or twice a day until the roots have established at around six (6) weeks.

If it has been raining, you can cut back on watering. Just make sure that the rain was enough to keep the soil moist.

Watering Established Instant Lawn

Proper watering aims to get the soil wet, not just the grass. Moisture needs to reach deep into the ground for the roots to have access to it.

Water deeply, less often

Once the instant lawn established its roots, you can water once or twice a week. 

Make sure that you water it enough to give it about 15mm of water each week.

If it rains, you do not need to water again until a few days later.

Be mindful of the weather so that you will not accidentally overwater your instant lawn.

Watering too little too often is harmful

Some people make the mistake of watering established instant lawn every day for shorter periods, especially during warmer weather.

Watering too little too often will encourage shallow root growth.

If water does not go deep enough, the grass will “learn” that their water source is only on top of the soil. 

It will establish its roots in the shallower part instead of going down deeper into the ground.

Frequent watering will also encourage thatching. Because of the shallow root growth, more organic matter will grow on and stay on top of the soil.

During hot weather, water could go to waste through evaporation if the amount of water is not enough to soak the soil.

Overwatering is bad

Too much of a good thing will cause more harm, and the same goes for water on your lawn.

Just like too little water is terrible, too much water will soak the soil and the roots, causing root rot and other lawn diseases.

Grass needs water, nutrients, and oxygen as well. Waterlogged soil will suffocate the roots and prevent them from absorbing oxygen.

Consider the Type of Soil

Consider the type of soil you have on your yard as it will also determine how often you need to water.

Loam soils will retain moisture better than sandy mixtures. Clay soils are prone to waterlog.

You do not need to water as often if you have clay soil, compared with loamy soil.

Sandy soil may require more water as it does not retain moisture as well as other soil types.
