Bonus S and Weed and Feed are both combination fertilizer and weed killer products.
They both have the same problem. Weed killer is absorbed through the leaves so needs to stick to the weed. Fertilizer needs to be watered in or it burns the leaves. It can't do both. I use liquid weed killers. It works faster. Unless your entire lawn is full of weeds,
I would spot treat only the weeds. It will take about two weeks for it to kill the weeds but in a few days you should see the weeds are starting to be effected. If, not since you are not doing the whole lawn you can give em another shot. I use a simple trigger spray bottle. You can buy them or just reuse empty bottles that come with many products.
For bigger areas, you can use a paint roller on an extension handle.
As to strength of the mix. Instructions on most products I've seen say one TBS per gallon. It is a balancing act. The products will damage grass-more so with St Augustine
and more so as the temperature rises. It says 70 degrees. This is Florida. Few people read the directions and far as I know my grass cannot read.
Timing. I have Empire Zoysia. First of all your last application of fertilizer is in October.
The first for the year is April. Applying a weed and FEED now encourages the weeds
your grass takes the winter off.
