How do I water newly seeded grass?
The main reason that newly seeded grass fails to take hold is lack of water. Until seeds have germinated and grown to about ½”, you should be watering your newly seeded lawn daily for about 15-30 minutes. The goal is for the area to be consistently damp. It is important for the watering to be gentle, so that the seeds are not washed away.
After grass has grown beyond ½”, waterings can be cut down to twice per week. After your new turf reaches a length long enough to be mowed, you can resume normal watering habits.
While the water routine for newly seed grass is certainly more extensive, be sure not to overdo your watering.
How do I water new sod?
New sod also needs more watering than established grass. The sod needs enough water to encourage roots to grow and take hold in the soil where it was planted. Failing to efficiently water sod will always result in sod death.
Sod should be watered daily, with a total of about 2-4” of water given a week for the first few weeks. After the two weeks, begin stretching out watering times to encourage the grass roots to grow down into the moist soil. Once the sod is firmly rooted, you can resume normal watering habits.
While the signs of grass in need of water often look like browning areas or a crispy feel, plantings tend to wilt. Drooping leaves or branches are signs that your planting is in desperate need of a drink. Watering your plants at the same time you water your grass will yield the best results.
Plants CAN be overwatered. Be sure to monitor new plantings surrounding soil to see if it is too damp, as too much water can drown trees, shrubs, and flowers.
