A: Your instincts are exactly right. There is no absolute need to add fertilizer when planting a tree, no matter the season. I am aware that there are "starter" fertilizer products available. Most contain a slow-release form of nitrogen and a high percentage of phosphorus as ingredients. It is possible the phosphorus might help new trees in situations where there is none present. That's not common in most landscapes. Almost all nitrogen that is applied will be wasted, since the tree cannot absorb it in cold soil. Research has shown that mulching a newly planted tree with three inches of arborist woodchips is an excellent post-planting treatment. The chips prevent weeds, control soil moisture, and slowly release nutrients as they decompose.
Q: I will be leasing two acres of land beneath some power lines. I want to develop a program that would cultivate bee forage, part of our effort to make Dunwoody a Bee City. I have support from local nature centers and bee clubs but am always open for more ideas, connections, and affordable sources of seeds and plants.

A: What an excellent idea; I wish you great success! There is a tremendous amount of information on attracting honeybees and wild bees available from the University of Georgia Bee Laboratory. I've put links to their great publications at bit.ly/beepasture.
