1) Can anybody identify the below pictured weed? I have small, but hardy St. Augustine yard in front of my wife's business. But, every fall, this weed shows up, and by spring, 90% of the St. Augustine is gone, and it takes till August before it's recovered and like a carpet. Is this chickweed? I've tried Pennington's St. Augustine Weed&Feed, but it didn't seem to touch it. 2) Also, in a duel between zoysia and crabgrass, which one will prevail? I have some zenith zoysia growing(2nd season) and the two are "fixin 2 duke it out"! If the zoysia will prevail, I'll just leave it be. 3)Sort of off topic question thrown in. Moles are running rampant on about 2 acres of my yard. In doing a quick search on here, it appears that the only way to get rid of them is to like crawl around with a flashlight trying to watch 200 tunnels at the same time to see which one is moving??? I mean Geez, there's gotta be something else that works that you spread on the yard??? Thanks in advance for any help on these things.
