Is there a granulated form of weed killer that I can use?

There are a lot of granular weed killers. They're just not as effective because you still have to water them into for the weeds to try and absorb them. That's best done when spraying directly on them with a water soluble solution.

I know the H&G Board has a lot of recommendations on water soluble mixes but I'm not too sure on anything granular. I used to use Scott's Bonus S and it was okay. If you really don't want to do it, maybe consider getting a landscaper to come out and do one big cleanse of your yard and be more proactive in the future.

Why can’t you spray? If too big for a backpack sprayer, get a tow behind. If you have a large yard and care about keeping it nice, invest in the right equipment.

Yes, there’s high up front cost but the results speak for themselves.

ETA: I’m not trying to come off as a dick. Like someone above said, the money you’d save over the long run with liquid would pay for itself. Looks like Amazon has a 15 gal tow behind sprayer w/boom (7’ width) for $270.

That plus figure out your chemicals for the grass you want to keep and weeds you want to get rid of.

Landscaper turned me onto to trimec southern. It works great but it’s a liquid.

Bonide has a granular product that works good. What about a hose end product? Assuming you can get a hose around in your yard. It is much easier than a pump up option
