The best time to sow seed is in the later part of the summer and into the early fall. The only investment you will have in seeding is that you will need to purchase the seed and either buy or rent a seed spreader. You will also need to purchase a top dressing to cover your seed bed. This can be straw or peat moss. Lawn aerators can be hired from any landscaping firm. The following steps will help you in getting your lawn properly aerated: The first important step before starting with your lawn aeration routine is to moisten the lawn soil by watering it thoroughly for a couple of days. For lawn aeration we need moist and not wet soil which may otherwise cling to the aerator’s tines.

One has to remember that if there is some rain during the summer months, the grass is going to be dormant. Before you go out and purchase grass seed, you should know what type of grass will grow in your environment and growing season. Do you need a cool season grass or a warm season grass? Cool Season Grass Cool season grasses grow best in the spring and fall. If you are planting a new lawn with cool season grasses, it is best to sow your seed in the early fall.

Also follow the instructions available on the fertilizer pack about the quantity to be used and how frequently they have to be applied before adding them to your soil. Here are some important tips to be kept in mind before applying fertilizers on lawns: Mow the lawn and moisten the soil before using fertilizers as a dry lawn can get burnt while sprinkling fertilizers.
