Fall is a crucial time to fertilize your lawn and landscape plants to help them stay healthy and come back in the spring, after the long, cold winter. Make plans to fertilize at the end of September or early October to help your landscaping recover from any issues it had over the warmer summer months. You can also look into nitrogen treatments that can be injected into your soil for trees and shrubs. When fertilizing and nitrogen treating your soil, make sure you have mowed the lawn, and cleaned up the area by removing any loose leaves, sticks, and more.

This will be one of the last things you do this fall though, as your lawn will still need watered before winter. You can begin to scale back on the amount you water, and make sure you water in the morning before 10 a.m. The later in the day you water, it will not soak into the soil as well and if sitting near the surface and stick to grass blades which can cause damage down the road. As you plan to wrap up your mowing, you will need to mow your grass until temperatures are consistently under 40 to 50 degrees. In your last couple mows for the year, make your mower trim the grass to be shorter.

In addition to fertilizing your lawn before winter, you will also need to mulch. This will also help to keep your landscaping healthy throughout the winter. Before you mulch, make sure to remove the old mulch and any debris in the area. Also, be sure to pull any weeds.
