The Chinese Elm bonsai tree, known as the Ulmus Parvifolia, is one of the most attractive bonsai trees available. It is categorized by its beautiful twisting trunk, small green leaves, strong branches, and fine twigs.
In fact, one of the main attractions of the Chinese Elm bonsai tree is the beautiful contrast between the thick and sturdy tree trunk all the way to the extremely delicate branches. They are native to Korea, Japan, and China, and extremely popular, especially amongst beginner bonsai tree enthusiasts.
It is very easy to care for and even more stunning to look at. The Chinese Elm bonsai tree tends to fair much better in warmer climates, where the leaves remain a magnificent shade of evergreen.
This type of bonsai tree does not fare well in cold weather conditions. They are best kept as indoor bonsai trees, as if they are left outdoors, the color will diminish and become deciduous.
|Scientific/Botanical Name||Ulmus parvifolia|
|Description||The Chinese elm is a study in contrasts: Its solid trunk is topped by slender branches and twigs, culminating in a graceful and arching tree canopy. When grown under ideal conditions, the tree is evergreen. However, in a less-than-ideal environment it will become deciduous and drop its leaves. The tree grows rapidly, and is adorned with glossy green leaves of heavy substance. It makes an easy-care and supremely eye-catching bonsai specimen.|
|Position||When grown outdoors, the Chinese elm bonsai tree can tolerate full sun in the spring. However, it requires some protection during the peak hours of the summer sun. The tree also needs protection from frost. When grown indoors — and this is preferred for the bonsai — a sunny location out of direct sunlight is best.|
|Watering||Water the tree to keep it moist but not waterlogged. Check on it every few days, water when the top one inch of soil is dry to the touch.|
|Feeding||The Chinese elm is not a heavy feeder. It only needs to be fertilized every three or four months, but never water the tree when it is devoid of leaves.|
|Leaf and Branch Pruning||Any major pruning must be carried out during periods of dormancy, usually in early spring. Shaping, pinching-out and light pruning may be safely carried out during the growing season.|
|Re-potting & Growing Medium||Younger plants that are undergoing more vigorous growth should be re-potted yearly. This should be conducted in the spring, before the emergence of buds. More mature plants can remain in the same pot for three or four years before re-potting. A rich, well-draining soil that incorporates organic matter and sand or grit works very well.|
|Wiring||Shaping is usually accomplished through pruning alone, so wiring is usually unnecessary. When wiring is undertaken, care must be taken so as not to break the rather brittle branches, or to damage the bark.|
|Notes||There are numerous dwarf sports of Chinese elm. They grow less rapidly, and are especially amenable to bonsai training.|
The Chinese Elm bonsai tree needs to be watered at least once every four or five days. Because this type of bonsai is primarily an indoor tree, it will absorb the water at a much slower pace.
Always check the moisture of the soil. If there is moisture an inch into the dirt, the bonsai tree will not require any additional water. A great way to check soil moisture is by taking a chopstick and inserting it into to soil, no deeper than two inches.
Let it stand for ten minutes and then remove it. Individuals should then feel the end of the chopstick. If it is moist, that means the bonsai tree does not need any more water.
However, if it is dry, then it does. A more scientific way of determining the moisture of the soil, rather than using chopsticks, is to purchase a moisture meter (amazon affiliate product) for the soil.
