You may need to water three times a day. You're trying to keep the seeds and the surface of the soil moist so the seeds will germinate.

Unfortunately, when you create conditions that are good for grass seed to germinate, you also create conditions that are good for weed seeds to germinate, so you will see more weeds sprout.

But fortunately your new dense lawn will choke out the weeds come next spring. The weeds that are sprouting now will be hard to see until spring. Now is a great time to look for a Weed Hound tool.
