Blackgum is a very slow growing tree, but can get rather large, upwards to fifty feet tall and fifty feet wide, so it needs plenty of space and shouldn't be planted under power lines. It seems this tree prefers a moist location, but will thrive in full sun and heavy shade, and is very adaptable.
Disease and insects do not seem to be a large problem with this tree as of now. In fact, it seems to be one of my favorite performers, as it tolerates neglect well, and gardeners love plants that are low maintenance and can withstand some neglect in our hectic lives. I often worry about some trees, but this one is never on the worry list.
Finding this tree for sale can be a burden, how ironic some of Missouri's best native species are so hard to find for purchase. If you are lucky enough to find this tree, and can give it a home, it will bring you and many other generations a healthy shade tree that will never fail to offer beauty in your landscape! Have a great spring!
