More information about this species can be found on the genus page.


An easily grown plant, it succeeds in almost any good soil, acid or alkaline, preferring a deep well-drained moist loam11RH. Prefers a moderately sheltered position11. Relatively shade tolerantRH. A fast growing treeRH. Dormant plants are very cold-tolerant, but they are sometimes damaged by late spring frosts when they are young11. Plants are susceptible to Dutch Elm Disease, but the beetle that is the vector of this disease rarely feeds on Zelkova so infestation is rare11RH. Plants in this genus are notably resistant to honey fungusRH.


Seed - best sown in a cold frame as soon as it is ripe. Stored seed requires stratification and should be sown as early in the year as possible78RH. Germination rates are variable78. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts.
