That's just great. Thank You! I hope I get to be that good with identifying plants. Thanks for quick response too.

Where did you take the pic of the beautiful blue flowering tree?

Thanks Carol. Thought so after searching a bit. it was just magically there in a planter.

Tenacity is a specialty herbicide and is not for novices. Weed B Gon, which you can find at big box stores, kills a lot of weeds. The best approach is to use that first and Weed B Gon CCO for weeds regular Weed B Gon didn't get. At that point if there are weeds left, find out what they are and what will work on them. For pre-emergents, I'd recommend Dimension or prodiamine. Where you buy them isn't important. I've bought Dimension at a big box store. Prodiamine is mixed with water and sprayed with a pump sprayer. A bottle will last for several applications. Dimension is spread with a spreader like fertilizer.
