Spring is coming and your lawn is getting ready to wake up from the long winter. But when is the best time to start mowing your lawn? The best time to mow your lawn is in early spring after the risk of frost has passed. You don’t want to shock your grass’s new growth by cutting too quickly. 

Once you’re sure the risk of frost has passed, before you mow, it’s important to prepare your lawn for the season. Applying a weed and feed fertilizer as part of your lawn care is a good idea before any mowing happens. Just remember to wait until after April 1, as it is illegal in Nassau and Suffolk counties to apply fertilizer before then. 

Once it’s warmed up, you’ve fed and put down weed control, and your lawn has started growing in earnest, it’s time to get your mower ready. When the grass has grown at least two inches tall it should be safe to cut. This helps to protect the roots. Make sure your blade is sharpened and adjusted so that you’re never cutting more than a third of its length in any single cutting. This will help the lawn grow lush and strong. Depending on your type of grass, as a rule of thumb, you should let the lawn reach 2–3” in length. 

To help return nutrients to your lawn it’s another good idea to leave some of the clippings where they fall so that they can decompose and release nitrogen. 

Finally, don’t water your “new” lawn right away. Wait until the heat arrives to wilt the lawn a bit. This will tell the roots to grow deeper which will help them to survive the heat later in the summer.
