All lawns can benefit from good fertilizer. Feeding your lawn correctly does more than just give it good colour as it also helps it to grow thicker and healthier. The healthier your grass is, the fewer problems you will have with and the fewer weeds and brown patches you will have to deal with each spring.
It would be beneficial to most lawns to be fed several times a year, with the most crucial time being in the early spring. The spring feeding should give the lawn a fast start, which will help to achieve that beautiful rich colour in the grass that you are looking for.
However, at Greenfield we also understand that it is just as important to not overdo it. If too much fertilizer is used, it could cause grass to grow excessively, leading to fungus growth and an unhealthy lawn.
