The Q&A Archives: Lawn Fertilizer/Weed Killer

Question: Can I use lawn fertilizer/weed killer on Asian Jasmine & Mondo grass? Ditto for lawn food?pre-emergence? Best brand/type to use? Another suggestion instead of hand pulling?

Answer: While the lawn fertilizer might be okay for your jasmine and mondo grass, I wouldn't use a weed and feed on either of them. Weed and feed products kill broadleaf weeds and it won't know whether your jasmine is a broadleaf weed or a broadleaf groundcover. Mondo grass might be damaged, as well. I'd use a pre emergent herbicide instead. Preen is registered for use in ornamentals, but there are other brands, as well. You'll need to remove any existing weeds before applying a pre emergence product.
