grass types: Buffalo and Bermuda with some fine fescue in the shade.
weed types: tons of spotted and prostrate spurge, dandelions, clover (maybe 2 different types at least) bitter lettuce, crabgrass, goosegrass, dallisgrass and a few goatheads that I pull whenever I see them, plus 2 other weeds I haven't been able to identify, both have puffy white seedheads like dandelions. One has a thick blugreen stalk with a single seedhead and milky sap, the other grows from a taproot and sends out 8 or 10 of the seedheads in a radial pattern like crabgrass.
I moved into this house about 4 summers ago, and have been fighting a losing battle with weeds ever since. I have tried spraying, laying down weed killer, pulling them by the bagful, planting more bermuda seeds to try to crowd them out, and I'm not having much success. Right now, the spurge is exploding all over the place, even in thick patches of bermuda and buffalo grass. This is a pretty large front lawn, about 35 feet by 70 feet, and there are patches of nice lawn and other areas with lots of weeds. There are also large patches of grassy weeds in the lawn such as the goosegrass, and when I raked up the thatch on my island on the other side of the sidewalk to reseed bermuda, tons and tons of spurge and also lots of goosegrass sprung up immediately. I've had to pick bags full of spurge on 3 different days to try give the bermuda seedlings room to grow and there's no way to get rid of all of it. I'm at a loss at the moment.
This year I got a new mower with a bag and started bagging my clippings, as well as letting the grass grow long and cutting it about every 2 weeks down to 3 inches, but things seem worse right now than they ever were as far as weed invasion. I just put down my first pre-emergent (Avert) last october and I put down some stuff that the local greenhouse recommended in April (I forget what it was?!?!?, I'm a dummy.) and I've been picking weeds all spring and summer. What else can I do? I'm thinking of starting to spray with Weed B Gone every month or so, my local greenhouse has recommended that I go with Image. any thoughts?
