I think my pastures will be ready to cut by the first of May. I have a few weed species growing out there and I don't want them in my hay. One is willd mustard, one is a short, purple weed that only grows in spring, and one is the weed the is sort of hard to describe. It looks like a thistley type of weed but some have thistles and some don't. They grow up and the seed heads get tall. I will try to post pics. Is now an ok time to spray for them? I have orchard, fescue and white clover pastures. TIA!!!!

If the weeds you want to target are growing, then it's time to spray them. I go after the mustard plants in very early May, usually, and after 5 years have them just about licked. I spray again in late June for the assortment of hot weather weeds that crop up, and sometimes once more to get the false dandelion in late summer.

you should spray before the plants are 3 inches tall...you can spray now but once you see "the colors" it's kinda too late for the broadleaf....you will also bump your clover back but the stand should stay up if your %'s are good

The purple you're seeing this spring is probably henbit, which is a winter weed. Target your winter weeds in Dec/Jan before they start flowering or seeding out. If you spray after the seeds have spread, you'll kill the mature weed but the seeds will cause them to come back again next year. So the earlier you can get them, the better! Target your summer weeds in May/June :)
