Start a monthly regimen of fertilization beginning next March (you'll probably have to apply twice in March to get a bloom, but after that once a month should do it) and fertilize March through October every year.
Walt, help me out on your fertilization program recommendation for DavidV�s pond?
I don�t understand your recommendation.
This is a disaster waiting to happen in our area � our ponds are only a few miles north of DavidV�s and we have to cope with high nutrient water problems from natural occurring events.
Maybe a one time jump-start with fertilizer or a bucket or so of muck from his other pond will produce fast occurring plankton bloom in our area.
