Having a luscious lawn won’t take a century to grow with hydroseeding—most hydroseed lawns sprout within 7 to 14 days. Once the new grass is about 4 inches tall, which is about six weeks after the installation, it’s ready to mow. After the initial mow, keep foot traffic at a minimum for another four weeks to solidify the rooting system.

Yes, it's common for lawns to look bare after dethatching. Dethatching brings soil to the surface to create a "bald" look on your lawn. While you may choose to patch or reseed your lawn if bare patches seem excessive, it's normal for a lawn to look bare after dethatching. With the layer of debris that was blocking water, nutrients, and air from reaching your grass now gone, your lawn is likely to grow better than ever.

You can thicken new grass by using fertilizer, watering it 1 to 1½ inches per week, mowing when it is at an optimal height, and preventing weeds. You should fertilize your grass while you plant the grass seed, or soon afterward. Use an herbicide to prevent weeds or spot spray with herbicide to kill existing weeds.

Due to its slow growth, Bahia grass does not generally take over weeds. In fact, the opposite can be true. Young Bahia grass is susceptible to being taken over by weeds. 

Likewise, in the cool season, Bahia grass goes into a dormant state that can allow weeds that thrive in early spring to get the upper hand. If you want to prevent weeds from taking over your yard, remove them by hand or apply a Bahia grass-friendly pre-emergent herbicide to your lawn before weeds have a chance to appear.
