Watering and mowing alone will not make a healthy lawn. It must be fertilized. We have included a starter fertilizer in the mixture applied, but it is only sufficient to supply enough nutrients for about 30 to 45 days. It is important for the development of a healthy lawn that a fertilization program be started at this time.
1 Before fertilizing,try to make sure your lawn does not have an excess buildup of thatch that can suspend the fertilizer in the grass leaves and inhibiting it from reaching the soil. Suspended fertilizer can also burn the grass leafs.  Avoid fertilizing your lawn during periods of drought or when it is excessively dry.
