Look online for the growth of the trunk of a tree. estimate how much time does it take for a water oak to grow one inch in diameter. estimate the growth rate over a year.

8 months needed to grow one inch in diameter by water oak and it grows 24 inches of height in a year.

Explanation:

In 2 different ways the trunk of a tree grows first the height than second in diameter usually in diameter tree grows one ring per year. We can say on counting the number of rings we can determine the age of a tree both of the growth does not occur in the same rate.

Tree grows more higher as compared to the  diameter growth and mature trees usually grows 1 inch in diameter every year.

Water oak gets 24 inches height growth every year and   1.5 inch growth in diameter annually means if we divide 1.5 inches by 12 months we gets 0.125 inches growth monthly.so we can say 8 months are needed to grow the diameter of water oak 1 inch.
