I got distracted and did not treat for clpw in the fall with Sonar A.S. as recommended. Is it possible to treat in the spring or early summer or is that a waste of time and money?
thanks.

Yes. Heck, you could cut a hole in the ice and put it in now! I'd just keep a watch on the water level. If your pond gets snowmelt, and it discharges from the pond, then dilution will be a problem. It has to stay in contact with the plant for 30-45 days @ the correct concentration levels.
