Answer: You didn't identify the tree, or its location so I don't know if it is getting too much or too little sunshine, or if it is simply a very slow growing tree. Some plants put on only an inch or two of growth in an entire year, others will put out several feet of growth. So, the slow growth may be natural for your tree, or it may not be getting the sun/shade it requires. Wish I could offer more help.
