If you've searched the net for "instruction on creating artistic topiary from pine trees and juniper" and have come up with nothing, I bet a trip to your local library might help you find books on topiary. Or, a book store where they may assist you in finding an instruction book that they can order for you. Another good source is a used book store, altho older gardening books get snatched up quickly.

I have limited experience with juniper - an Irish Juniper that I keep in a columnar shape and an older Juniper hedge that I'm currently trying to create a big block shape, with a smaller block on top, then a ball on top of that, at the very end of the hedge; so have no real tips to share. Other than - ouch. Those dead and dying needles are killers if you don't clean up the trimmings before they become dry and brittle!ha.

Did you notice the video on that Plants Beautiful Nursery site, the one where the bonsai expert is trimming the pine tree? It's a very short video but interesting.
I know that when I've trimmed the tips of the branches of white pines trees at my house, the rest of the branch tends to die.

I searched what you suggested. Just the same little bonsai trees. I played around though, and tried YARD BONSAI, which gave some results. Getting closer but still don't have an idea of clear instructions or a good book. I can't stream video because I am on dial-up.

Thanks for tip re cleaning up - makes a difference.

I got some cheap mugo pines and I am going to play with them and see what happens. I am more interested in sculpting the trunk and branches than getting little pom-poms on top. So I won't be trimming the tips/candles much. I guess the only thing to do is experiment with a $5 tree.

Did you check at your library for books on the subject?

If you won't be trimming the tops of the juniper and only the trunk like you say, I feel you'd be safe in just clipping and pruning away any side branches you don't want, leaving two or three main trunks or how ever many you wanted. I don't see how you could kill a juniper in this way as long as you leave some foliage. Will you be working on large existing shrubs (which to me would be easier) or young potted ones? I think your idea to experiment on a $5 tree is a good one.

Probaby play with cheap young ones, esp since I have no established trees to work on. I was wondering about cutting out too many side branches, and how you tell if you are going too far. Probably won't trim tips much - I like them wild.
