Yes, grass will regrow after forestry mulching, but the timeline depends on soil conditions, mulch thickness, and existing seed banks. The nutrient-rich mulch left behind helps retain moisture and improve soil health, encouraging regrowth. However, if the mulch layer is too thick, it may block sunlight and slow grass germination. For faster results, you can rake excess mulch, aerate the soil, and plant the new grass seeds.

Morning and late afternoon are the best times for watering new grass seed. The seed gets a healthy balance of water and sunlight, and the excess water evaporates. If you water the grass long after the sun goes down, the air is too cold, and there's no sun to make excess water evaporate. This keeps the grass damp for too long, increasing the chances of over-watering.

Aerating a lawn before seeding it or adding new grass seed is a smart decision. By loosening up compact soil and allowing it to take in more air and water, your seeds will have an easier time establishing roots and growing. Aerating beforehand also means your seeds will have better contact with the soil, so more of your seeds have a chance to germinate. If you do plan to aerate your lawn before seeding, aerate about two days before you plan to start seeding.

When stored under ideal conditions, grass seed lasts anywhere from 10 to 18 months from the testing date without any real decrease in the germination rate. You can still use the seeds after this timeframe, but the germination rates drop 10% to 20% each year. 

If you’re just embarking on an overseeding project, using seeds that have been in storage for a few years isn’t too big of a deal. However, if you’re planning on redoing your entire landscape, your best bet for a healthy, luscious lawn is to use new seeds.
