Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Should I Control These Plants ?

I have heard southern guys state Primrose can be invasive, but I've not experienced it up here so I'm not certain. I've never heard of sedge being invasive [but that doesn't mean anything]. I encourage all shoreline grass to establish and spread to help control erosion and utlize as many nutrients as possible so less desirable cultivars don't get started [FA, heavy plantonic algae blooms, etc.]. At least up North the sedge I encounter is always confined to very shallow water and is considered a benefit and is usually short. I at least would prefer sedge to cattails any time.
