funny, I wish I had rosemarry bushes that did that. mine keep low to the ground. If you prune the top, they should become more bushy I would think.

Your rosemary is probably doing what it should be doing for its type. Read on to find out what types to buy and how to grow, prune, etc. Btw, I have both the upright and prostrate forms and I recently cut both way back to encourage new growth. It's working and I'm happy. ;o)
