We have a great line of lawn food and fertilizer from Jonathan Green. Their program is more than just NPK, it treats the lawn as an ecosystem and has an increased focus on soil quality for a healthy lawn year after year.
They also happen to offer the best grass seed we have seen, Black Beauty Ultra, that we stock in three sizes, we also carry local blend that works great for large jobs.
If you are thinking about planting grass seed do yourself a favor and dramatically increase your odds of success with Germination Blanket. We offer two roll sizes as well as a couple sizes of baled straw to help get that grass started quickly and with less water.
