Preventing Lake Weed Problems Southern Ponds & Wildlife Vol. 3 #1 (Winter 2004) Don C. Keller   Every spring during the months of April and May, I get hundreds of calls from pond owners who seem to be overwhelmed with vegetation problems.  They usually state that they began fertilizing in March and had difficulty establishing a desirable plankton bloom (green color).  What they fail to say is that there was some vegetation in the pond when they began fertilizing.  The reason they couldn’t get a bloom was because the vegetation was sucking up the fertilizer.
