Q: If my lawn is very healthy, can I still transition to Pearl's Premium?
A: Yes, you can. However, additional effort will be required. First, stop applying any fertilizer 3 months before over-seeding. Second, kill the existing lawn with an organic grass and weed killer like Phydura. Third, follow the detailed over-seeding installation instructions . Once installed, you should closely follow the low maintenance lawn care instructions  to help the Pearl's Premium out-compete any remaining old lawn and expect to over-seed the second season to continue the transition.
