Lawn

Overfertilizing can burn and kill the grass as well as upset the soil's nutrient balance, leaving your grass prone to disease and infestation. You'll know that you have overfertilized your burn when you have recently fertilized and begin to see brown and yellow patches of dead grass that need to be reseeded. 

Treating dry soil can bring back a dormant lawn, but not a dead one. After nurturing a dry lawn back to proper moisture levels, you should closely observe whether your grass revives with the soil. If not, you may need to reseed your lawn or start fresh with new turf.

Along with helping your grass grow in thicker and healthier, overseeding better equips it against hungry insects, common lawn diseases, drought, heavy foot traffic, and other foes that can weaken or kill the grass over time. By investing the extra time and money into overseeding, you’re lowering potential costs of fertilizer, pesticides, or possibly reseeding the lawn in the future.

Yes, but much depends on how much damage they’ve done before they are stopped. By the time grass turns brown it’s mostly dead, and chinch bugs can be very destructive, hindering the grass’s ability to recover. Over time, with plenty of water and the proper fertilizer, grass can usual grow back. However, you may want to consider reseeding and similar options to help it along.
