During the winter when the grass is dormant is the best time to see how well your lawn care program is working. Since the grass should be a nice golden or brown look your weeds will be easy to spot. Notice how some yards will look thin and you may even see the dirt in some cases. If you fed the grass correctly during the summer you will have a plenty of thick dormant grass blades left. It may not seem like it but now is the time to apply your pre emergents for the Spring time. Lawn care is a very pro active process and timing is everything. Make sure to follow the proper application rates on the label of the product you choose to use. If you have any questions or need any suggestions feel free to ask!
