My lawn is less than 1000 sq ft. Do you sell smaller bags of fertilizer. A 40 lb bag will last me several years.

How long does fertilizer last in your bag? Do I need to buy a fresh supply each year?

BEST ANSWER: No sorry that is the only size available of these bags of fertilizer.

Reseeding with centipede, how long should I wait?
Rich on Mar 8, 2017
BEST ANSWER: Yes, the Imperial would be a good fertilizer,

Weed Control: Apply broadleaf herbicides as necessary for control of chickweed, henbit, and others. Centipedegrass is sensitive to certain herbicides, such as 2,4-D, so follow label directions for reducing rates and use with caution. Selected herbicides (e.g., atrazine) can be applied in November or December for control of annual bluegrass and several winter annual broadleaf weeds.

Already Greening Up
This was my first time to buy this product. I read about it on a website and decided to try it along with their fertilization schedule. It seems like the grass is already turning greener and it's only been a couple weeks since I applied. The shipping was super fast also and the cost was slightly cheaper than buying it at my local nursery.
