You just need to be careful. Don’t let it dry but give it enough time to work. We go about 10-15 minutes dwell time. Some folks downstream strait from the bucket, this mixes it with water. We’ve had good luck doing 50/50 in a bucket and downstream. Start with 50/50 and see if that works. I’d rather redo than put too much. Water any plants that might get over sprayed. Water them real good. Water them some more when you are done. Just be careful and you should be fine.
