Thank you - that's very useful information. As this is old ranch land that hasn't been touched in 10 years+, we have to start over. We have 1/2 acre that is deer fenced for a vege/fruit garden but needs to be planted (soil improvement, first). Also, no landscaping is left around the buildings so that needs to be done as well as planting tress, etc., in the belt areas. So... a lot of work and varying plants and crops. About the only thing that is in relatively good shape is the main pasture.
Unfortunately, we cannot just mow or plow it all as there is too much land for that to be feasible and there are several steep drop offs that, although brushy, really can't be cleared (great breeding grounds). For now, I guess we will start with Semaspore (long-term help) and keep researching.
I appreciate the link - it gives me a good starting point for more research. I am curious, though, how does everyone else deal with these?
