Ulmus elliptica Koch (named for the elliptic samara) is a disputed species of elm, native to the Caucasus, where Koch reported (1849, 1872) that it formed extensive woods, and ranging north to southern Ukraine. The tree is said to be closely related to U. glabra, but to resemble U. rubra in its samara (see Description below). Many authorities consider U. elliptica Koch just a regional form of U. glabra, though Henry, Bean and Krüssman list the Caucasus tree as a species in its own right. U. elliptica Koch is distinguished from U. scabra Mill. [:U. glabra] in some Armenian and Russian plant lists.For a time, the Späth nursery, Berlin, distributed a disputed cultivar, U. Heyderi, as a synonym of U. elliptica Koch (see Cultivation below).
The wych elm is well resistant to disease and, overall, is not prone to illnesses. Regarding care, this species is fairly low-maintenance. When grown outdoors it needs only minimal watering, and larger specimens typically do not require pruning. Smaller plants, however, should be trimmed after they finish blooming. The wych elm is suitable for anyone with an outdoor area, such as a garden or deck, and does not demand much prior care experience.
How to keep Ulmus Elliptica.
Light
The wych elm does best with a plentiful supply of sunlight, though it can tolerate less favorable conditions with only moderate light. It originates from an environment with abundant sun. Too little light can restrict its growth, while too much light can harm the plant.
Temperature
Wych elm naturally grows best in temperatures between 5 to 35 ℃ (41 to 95 ℉). The plant favors moderate conditions and can have difficulty when temperatures are very high or very low. During colder periods it may benefit from protections like burlap wraps or mulch placed around the base.
Fertilizer
To encourage healthy development, fertilize your Wych elm in early spring. Regular applications of fertilizer improve overall health, leading to vigorous growth, increased tolerance of harsh conditions, and stronger resistance to diseases and pests. Keep a consistent fertilization schedule for your Wych elm to maintain vibrant, deeply colored foliage and a lush appearance.
