I got this from the new issue of railroad model craftsman magazine, and it works great. I took some floral wire (26 gauge) and floral tape, using 10 strands of wire about 4 inches long (this is for n gauge, not sure how much you'd need for ho) I twisted them together and then separated and bent them into tree trunk shapes then wrapped them in the floral tape. I painted them brown, then attached clump foliage to the tops. It turned out fantastic, and its so cheap! the wire and tape was about a buck fifty, and in n scale this will make many , many trees, so much cheaper than buying the plastic tree kits, and I think these look alot better even...I included a couple pics one is a finished tree, and the other is trunks waiting for paint.....If anyone is interested I can post a better explanation, I made a small jig from a piece of wood and a couple nails to quickly measure the strands of wire, and after a couple practice tries, can knock one of these trees out in about 10 minutes! Sorry the pictures arent great.....my digi camera is showing its age.....
