The Ulmus Parvifolia (Chinese Elm Bonsai) has a very fine network of twigs and branches, making it perfect for Bonsai purposes. The Elm is often confused with Zelkova species, but when comparing both leaves the difference is noticeable. The Chinese Elm is the most commonly used Elm species, although its other varieties are also suitable for growing Bonsai trees.
Position: Grows well in both sun and partial shade. The Ulmus can withstand cold well and can (should!) be placed outside also during the winter. An Ulmus bought as an indoor tree can be placed outside as well, but protect it during the winter, or place it inside in a cold but bright room.
Watering: Slightly moist, no particularities.
Feeding: Fertilize monthly during its growth season (spring-summer.
Pruning: Reacts well to regular pruning, which will result in the tree growing a dense branch structure. Allow shoots to extend 3 or 4 nodes then prune back to 1 or 2 leaves. When pruning large branches of the Chinese elm bonsai tree, wait till late autumn.
Repotting: Repotting can be done once every two years, using a standard potting soil.
Propagation: Only by cuttings.
