OK, this is our first house we bought last June, and the lawn has some problems, mainly stickers, both sandburr type and goathead (little white flowered plants with small stickers). there are some other common weeds like dandelions and such, but not as prevalent as the stickers. The lawn is mostly bermuda with some fine fescue that outgrows the bermuda in the shade. When do I need to start putting down some stuff to help the bermuda take over and kill out these stickers, and what?? What can I put down that will kill the stickers?? will a weed & feed work good? separate products? lawn is very compacted but I hope not to have to do anything about that. I will also be planting acorns around the yard to try to get some oaks going. Any suggestions? We are on the edge of area 6/7, but it's more like 7 here.
