Profile JumpStart can only be applied at seeding, not to existing turf.
We recommend using products like the Profile JumpStart and BioPrime in hydroseeders since that is the application for which these products were designed. The product labels do not offer smaller application rates. You could contact Profile Products directly for more questions about their use rates. You can reach them at 800-508-8681. We also carry a wide range of other fertilizers that you can browse here, many of which will cover a wide range of area sizes. We have lots of great all-natural and organic options, too. Please let us know if you need assistance selecting a different product for your needs.
