My husband and I recently bought a house in a relatively undeveloped area of Queen Creek. When the weather started to warm up, we realized that we are absolutly and completly plagued by tumbleweeds. They blow over from the empty lots and have taken a firm grasp in my yard. Does anyone have an effective method of getting rid of the tumbleweeds that have already taken hold (we are having a nearly impossible time just pulling them because of the break-away stalk design) and for keeping new ones from sprouting? I've tried Round-Up, but it doesn't seem to be working very well. We currently don't have any landscaping aside from a few trees, so I don't have to worry about saving grass or other small plants, but I do plan on planting in the yard come cooler weather so I don't want to competly contaminate the soil.
