i've been living at this house for 3 years. first two years i;ve been working on the front yard. its now 99% dallis grass free. lots of pulling and digging, many 5 gallon buckets full.......

now for my backyard. its about 25-30% dallis grass. ive been searching on the internet. does any have any experiences with the organic crabgrass killer? their site says some of their customers use it for dallis grass.

also, any experiences with bayer advanced for southern lawns. i have st. augustine but not the floratam variety.

tyvm.
