I have a couple pom pom pines and one pine shrub that seem a bit over grown. How can I help them become more defined and dense? The stems coming from the pom pom branches only seem to have needles on the last third; the inside is mostly bare or dead needles. Is this normal or a sign of a poor maintenance? Is it permanent? What, if anything, should I do with all the new candles? Here's are the photos on flickr: http://www.flickr.com/photos/7733933...th/6942753670/ I took these photos today.

Thanks for any suggestions. I'll be sure to follow up.
