Your go-to guide for Fall overseeding
Shouldn’t I wait?
A few reasons to begin preparing and overseeding your lawn: The best lawn for overseeding is a dormant one. Even though the temperatures are starting to drop, the warm soil helps seed germinate faster. Weeds don’t grow or germinate during cool fall days, leaving your grass with absolutely no growth competition.
These are the steps you need to take to properly overseed your lawn to ensure a rich, healthy looking lawn throughout the Winter. (**Moon Valley Professional Tip: We absolutely recommend using Perennial Ryegrass for your lawn. It’s the only reason we carry one type of ryegrass seed: Perennial. If you choose to use another ryegrass or some other seed, these tips will work just as well...but you should really use Perennial)
- Make sure your lawn has not been watered recently before overseeding. This makes your overseeding efforts a lot easier.
- Mow your lawn to ½ inch or at the lowest possible setting. Remove all dead grass and debris to ensure good contact between the new seed and soil.
- Loosen the soil using an appropriate method (roto-tilling, aerating, or heavy raking) based on the hardness of your soil.
- Prep your soil using a very thin layer of starter fertilizer, this can be purchased at all Moon Valley Nurseries. This will help the seeds germinate and provided additional nutrients for the seedlings to thrive.
- Spread the Perennial Ryegrass seed evenly in a side to side, up and down, and diagonal pattern (1 lb per 100 sq/ft for normal density. For extra density apply 2 lbs seed per 100 sq/ft.). We recommend using a little more seed to make up for the seedlings that do not germinate, are washed away, or are eaten by birds. After all of the seed has been spread apply a top dressing of soil or mulch over the top of the seed. Applying a top dressing also keeps the moisture in the soil and keeps the seed warm enough to germinate. Top dressing or mulching also will help to prevent wash off and birds from eating the seeds before they have a chance to germinate.
- Water your lawn completely immediately after overseeding. Continue watering your lawn 4-5 times daily for 3-5 minutes. (Future watering schedule: Once you begin to notice sprouting you can cut back to watering 2-3 times a day for 5 minutes. Once the grass has grown to 3” + in height you can mow your lawn for the first time. Reduce watering to 8-10 minutes daily. After your second mow you can reduce watering to every other day for 10 minutes. The idea here is to keep the seedlings wet in the beginning and watering less frequent and deeper as the root system begins to grow).
- After you have mowed your lawn twice apply Moon Royale Turf Fertilizer throughout the season to ensure a lush, healthy lawn throughout the winter. Keep your lawn cut to a height of 2 inches for the rest of the season.
- Pat yourself on the back as your envious neighbor begs for your superior lawn care and maintenance tips.
