With generous rains this year it seems the weeds are thriving. We are a fairly new, small operation working on pasture improvement. Our war on thistle the last 5 years has been successful however the mint weed and sericea are just awful. Do most of you spray yearly to keep all weeds at bay? We're thinking of buying a sprayer and getting a chemical license. When we were getting started, we paid to have the pastures sprayed to get the thistle under control and the last 3 years have simply spot sprayed or dug the few we have. Now we're overwhelmed with various other weeds. Interested in hearing about your practices and recommendations. We are applying 3000 lbs/acre of lime next month as recommended by our soil test. Thanks in advance.
