Answer: It's true that a crown reduction will lower the height of a tree and slow its growth as it recovers. Other ways to reduce the size of your tree include drop-crotching and root pruning. However, it will be an on-going process to keep the tree small and can eventually turn into quite an investment. As you've discovered, pruning stimulates new growth, especially if done at the wrong time of year. If you're afraid the tree will outgrow its site, or become a nuisance, I think removing it now while it's still relatively small (for a tree!) would be your best course of action. For other opinions, phone your local Cooperative Extension office (909-387-2171) and ask them for a list of certified arborists in your area. An arborist can assess the tree and predict its growth rate, after which they can make educated recommendations based upon the tree's health, size of the site, etc.
Best wishes with your pine!
