The University of Florida has created the most informative, practical, and useful guide that I have found online to teach the various aspects of pruning landscape trees. Pruning Shade Trees in Landscapes provides detailed instructions on the many types of pruning and even includes excellent diagrams, photos, and animations of the pruning techniques described.

Reflective Foil for Stronger Transplants
Transplants growing indoors often lean toward a window, growing rather lanky as they strain for more light. Attach aluminum foil to a piece of cardboard and place it on the side of the plants opposite a window to reflect light back from the other side. Turn plants daily to help build stockier, more upright transplants.
