The Zelkova is very similar to the Ulmus (the Chinese elm), but it has single-toothed leaves whereas the Ulmus has double-toothed leaves. The Zelkova leaves are ovate, toothed and pointed.
Position: Although an outdoor tree, when acclimatized to indoor conditions (often the case when bought in a garden center or so) it should be kept indoors at least during the winter. Otherwise, protect the tree during the winter. The tree prefers much light, not necessarily direct sunlight though.
Watering: Water regularly as usual.
Feeding: Fertilize the tree once or twice every month from spring till autumn.
Pruning: Allow shoots to extend at least 3 nodes then prune back to 1 or 2 leaves. Larger-leaved Zelkovas respond well to leaf cutting in summer.
Repotting: Repot the tree once every two years, less often when the tree matures, using a basic Bonsai soil mixture.
Propagation: Use seeds or cuttings.
