PREEN and all the other "weed preventers" can kill some types of plants. Swan Island Dahlias warns Dahlia growers NEVER to use any type of herbicides around Dahlias.
You should ALWAYS read the label before applying anything around your plants.
I used PREEN&GREEN this year for the first time and I have to say I really love this stuff. I applied it after I mulched then watered it in twice. Once one day then a little more the next. Re-applied after one month right before a rain. I cannot speak about the effect of the slow release fertilizer but I can say I have darn near zero weeds and my flowers are doing quite well. The annuals I used it on are in the same beds as perrenial flowers and shrubs like lilies, asytum (sp), Azelia, Holley, and Stella-Dorra Lily. Make sure you weed very well and chop up the soil before you apply.
Next year I think I'll try just the straight PREEN and see if there is a differance. I'll either fertilize with a watering can or buy a seperate slow release fertilizer.

it works great on grass, but really only in the spring when the weed seeds are germinating. I sure wouldnt use it anywhere you want flower seeds to germinate... many of mine come back every year from seeds. Ingrid

Wouldn't plain old crabgrass preventer have the same effect? And a bag of this is a lot cheaper than a box of Preen.

Will only have the same effect on crabgrass (it is target-specific), but will have virtually no effect on broadleaf weeds.
