giant sequoia growth per year
The giant sequoia given good conditions and good gardening techniques will put on growth rings of one inch per year. That would increase the trunk diameter by 2 inches per year.At that rate you could expect the tree to have a trunk diameter of 20 inches in its 10 th year, 60 inches in its 30 th year, 100 inches in its 50 th year, and 200 inches in its 100 th year. 200 inches is nearly 17 feet in trunk diameter.e expect 4 feet of upward growth in the third year for trees in large pots and one-inch plus growth rings. They have the potential to grow faster every year. Giant sequoias grow rapidly tall and less dense when the rising and setting sun is blocked.
