A tree standing alone and placed in open sunlight can produce more mass, but has no specific need for being tall. Thus a city tree usually looks older and more massive than its comparative fellow in the forest, but not necessarily as tall. Take a look at trees growing on a hillside. Those in the lower regions are commonly taller than those on the peak even if the latter are not exposed to heavy winds etc. Overwatered, then dried out, now leaves are wilting, is plant in shock or dead.
Plant is three years old.
Plant is indoors in winter and outdoors in summer. We are in climate zone 5. If overwatered and then dried out it is definitely in trouble, roots suffering from both conditions. When overwatered they may choke, as they must have access to oxygen. When dried out they die.
