I have always had trouble trimming my spherical topiary plants. I recently found this new form of trimming frame which provides perfect shapes and is very quick to use. It is attached to the plant for the trimming and then removed. The end result looks like a perfect sphere which has been hand trimmed. The best thing is that it is very quick, and can be used over and over again on different plants. Since you take it off the plant once trimmed nobody knows that you used a guide! I would recommend it to everybody. Send me an email and I will forward you the link to where you can get one!!!!
