Watering your new seeded lawn is not as simple as dumping a ton of water on it every so often. Too much or too little water are both unsuitable conditions for your lawn to grow. Overwatering can wash away seeds that have not yet taken root. Too little water will dry out the little sprouts and they will die.
So how much water does grass seed need? Let’s find out.
How Long to Water New Grass Seed
Prepare the soil with a good watering before you plant the seeds. 6 to 8 inches is a healthy amount of water for the soil several days before planting.
With new grass seed, the aim is to keep the soil moist. Waterlogged soil will suffocate the new seeds. It is best to water the grass seedlings 2 to 3 times a day for about 5 to 10 minutes each time. This way you replace any water that has evaporated without oversaturation. It amounts to 3-4 inches of water per week.
Once the grass seeds germinate, you should water for a longer period once a day. The frequency of watering should slowly reduce to a long soak of about 40 minutes on alternate days then cut down to 2-3 days a week. The aim of watering after germination is to assist the grass to form deeper roots. For this, less frequent watering is required.
Keep careful track of the weather. Showers and heavy rain will tell you how often to water grass seed. Skip the watering session after rains.
Install a decent sprinkler system with a timer to automate this. Watering the grass early on Saturday morning may not seem appealing.
Before watering the new grass seed for the first time, you need to protect it from evaporation. Spread straw mulch all over the seeded area before watering.
Water before and after the day’s hottest hours. This lets water sink into the soil before evaporating and conserves water. Nighttime irrigation encourages mold development.

Can I use a sprinkler to water new grass seed?
Watering young grass seed requires daily watering. Set morning and midday automated timers for 5–10 minutes. Hand or hose-end sprinkler watering must be uniform.
When should I stop watering new grass seed?
Do not allow the top ½ inch of the soil to become dry until the grass is 1 inch tall. Once the grass is 1 inch tall, water the grass every other day until grass is established (approximately three weeks). Once the grass is established, revert to watering 1-2 times a week for a total of approximately 1 inch of water.
How often should grass seed be watered until it germinates?
twice a day
To keep the top two inches of soil wet, new grass should be watered twice a day. Water daily until all grass seeds germinate, then start a regular watering regimen.
Should I water new grass seed before rain?
Step 1: Water grass seedlings everyday, even on rainy days. Overwatering grass seedlings before or after a storm is bad.
Does rain help new grass seed?
Keeping the soil wet helps freshly planted grass seed survive wind and mild rainfall. However, strong or sustained rain after spreading grass seeds might cause problems. Grass seed may wash away since it has no roots.
Can I water grass seed in the sun?
Water grass seed early in the morning or after sunset. Watering in direct sunlight is inefficient and hazardous since water evaporates quicker in heat.
