Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Lawn chemicals near pond/algae

would lawn chemicals used by such companys as TRU-GREEN contribute to a problem of excessive algae?

i have them stop well short of the pond for fear of this but really, when it rains enough, it all heads for the pond....thanks.

Don't know about Tru-Green. As a general rule fertilizer washing into the pond can cause over fertility and excessive algae growth.

I wouldn't be that crazy about pesticide/herbicide runoff, either.

Along this same topic, I've had several people recommend putting 13-13-13 into a pond on purpose. They seem to be convinced this makes the pond "healthy" and "clear". I'm not sure I understand how this helps an otherwise healthy pond balance?


Jeff-

In most cases the pond , if it needs fertilization at all, does not need N of K. P is the limiting factor so most pond fertilizer is for example 0-46-0 or 8-52-12.

Thanks ewest. That's good info. I guess my biggest confusion was that a couple of ole timers thought fertilization was needed as a routine, regardless of water condition or balance. When I suggested checking the water first, I got that "these kids today" look. (I'm 43)


Jeff-

We have banned the use of phosphorus in our 550 home, 6 lake community after testing the water coming in through the storm drains. We suggest only slow release granular p-free fertilizer and are trying to get people to do four or less treatments, and a core areation so that the ground does not get hard and allow for run-off. This is a challenge. We are working with Scott's company and find them the best as their employees are certified, and come equipped with blowers, baffles and brooms. Our objective is less algal blooms, not heavy fertilizing for a more productive pond.
