Lawn Fertilization and Treatment questions, answered by experts

Fertilizing is optional after dethatching. However, the period immediately after dethatching is generally considered the best time to fertilize your lawn because the thick debris is now gone. As a result, applying water and fertilizer as the final steps of dethatching can help to spur incredible growth.

If it’s been a few weeks and you haven’t seen anything pop up, double-check your seed packet and make sure you didn’t miss any steps. Did they need cold stratification (putting seeds in the freezer and then transferring to water before planting)? Do they have an exceptionally long germination period? 

 If you’ve followed all of the directions closely, you may just have had a bad batch of seeds. (Sadly, it happens.)

Quack grass is a perennial plant that will continue returning yearly until you eradicate it above and below ground.

Yes, in most cases, grass will return after your dog urinates on it. But without preventative measures, there’s always a chance your dog will pee on the grass again, leading to brown patches come summer. This aside, even if your grass is dead in patches, simply reseeding the dead spots should help restore your lawn. 

If you choose not to reseed your lawn, unaffected grass surrounding the dead patches will spread over any dead spots. But be prepared for this option to take longer—you likely won’t be able to grow grass fast.

Most businesses schedule services weekly or biweekly to maintain a professional appearance and healthy lawn.
