Should I fertilize a newly planted tree?

Question: 

Should I fertilize a newly planted tree?

Answer: 

It is generally not necessary to fertilize newly planted trees.  Most Iowa soils can supply sufficient amounts of nutrients during establishment.  If trees are growing poorly 2 or 3 years after planting, fertilization may be beneficial.  Poorly growing trees often exhibit sparse foliage, yellow-green leaves, or short annual twig growth.
