Does anyone know of a web site where by video they show how to cut back annuals and perennials?

No I don't know of any videos.

But this is NOT difficult! For annuals, you should cut off each flower as it dries up. You can either cut just below the flower or you can cut the entire stalk with dead flower (depending on the plant). Sometimes you want to let the flowers "go to seed" so that you will have new plants in the same area next year!

Perennials are similar, except in some cases you don't want to cut off the stalk!!

You can always take a flower with you to your local nursery and ask a professional how to cut it! They LOVE to give out this kind of info!

Good Luck!!
