Q: I just bought a large tow-behind sprayer. I would like to use it to apply liquid to my one-acre lawn. What’s the least expensive fertilizer to use?
A: The best product for your situation is one of the granular products designed for use on lawns. Liquid fertilizer is a bad idea because it is used immediately, with nothing left to nourish the grass for several weeks until the next feeding. Lawn fertilizer is manufactured to release nutrients gradually over several weeks. This is best for a good lawn health.
