|what to do or apply to the lawn to get the deepest
dark green color lawn?
Nitrogen fertilizer gives a lawn its deep green color. However keep in mind that some turf species such as Centipede and St. Augustine are less green in their natural healthy state. Centipede can suffer from being "pushed" with fertilizer and St. Augustine would rather be a chartreuse green than deep emerald green. If you fertilize any turf a lot it will develop more top growth requiring more mowing and less roots making it more susceptible to drought and grub injury. It will also be more prone to some insect and disease problems.
Thanks for the question. Please stop in again soon!
