It turned out we had to spend hundreds of dollars to have someone who had bushhawk with the mowing equipment to mow the land.

How can we maintain it without having many weeds grow or at least just preventing the hardwood bush weeds or trees from growing??? I am thinking of spread pre-mergent at early October, yet I am not sure how effective for maintaining the empty land.

Please advise. Thanks

Howcum I have no sympathy for you....you bought the property to do something with I take it....and the weeds are taking over.
Thankfully, jurisdictions have laws and rules against letting property owners treat land just as they please....otherwise, we'd all be inundated with neighbors who could care less about their's and their neighbors properties.

High weeds breed insects and may contain noxious types that people find their allergies acting up and can make a neighborhood look too country.
Chances are if you didn't keep the weeds down there would be lots of complaints from neighbors.

Thank your lucky stars you have laws that control such nuisances.

I have an acre with a home near the Texas desert. All the lots are the same. I have half in lawn and the rest is wild. My neighbor offered to mow it for $20 so I went for it. In this drought nothing has grown back although a recent inch of rain has done wonders for some weeds.

Depending on where the lot is, there are some pasture grasses that don't look terrible when they are mowed down short. Many don't take much water.
