The 8 charts below show the tree circumferences (3 inches from the base) and heights from 2012 to 2020 (apart from 2013 when I didn't measure the heights). The apparently abrupt increase in the Bald Cypress trunk circumference from 2015 to 2016 is likely due to measurement error which is exaggerated for this tree due to the highly tapered trunk at the base. Most of the trees have grown in trunk circumference steadily every year apart from the trees that have been noticeably lacking in vigor, such as American Hornbeam, Darlington Oak, and the BBB Magnolia. Overall not much additional increase in circumference in 2020 with a few exceptions: Black Willow, Eastern Cottonwood, Ashleaf Maple, Cedar Elm, Loblolly Pine, Sugarberry, Nuttall Oak #1, Montezuma Cypress, and Water Oak, all of which increased their girth in 2020 by at least 3 inches. The apparent increase in girth of the Carolina Basswood is due to two separate stems becoming fused.
Tree heights measured over the years are shown in the four graphs below. Increase in tree height in most cases has been quite gradual, with notable exceptions being the Eastern Cottonwood, the Sugarberry, and the Sweetgum which was planted as a bare-root stick. In general, not much additional increase in height in 2020, with a few exceptions: Ashleaf Maple, Black Willow, Red Mulberry, Eastern Hophornbeam, Black Locust, and "Pumpkin Ash" all grew in height by at least 3 feet.
