Bonsai elm is one of the easiest bonsai trees to care for. It’s slow growing and very tolerant, making it perfect for beginners. It also adapts well to indoor conditions, but is best kept outside in summer.
Chinese elm bonsai have beautiful and distinctive bark, ranging from gray-brown to reddish-brown with irregular texture patterns. They are also known for their interesting branch structure, especially in autumn when they turn vibrant shades of orange and yellow before they fall. They’re also quite forgiving to pruning, and back buds very reliably. They’re very easy to wire as well.
Like all deciduous trees, Chinese elms need to be kept cool in winter. They’re best kept in an unheated greenhouse or foil tent. In the apartment they do well in a bright position, but should be placed close to the window to keep up humidity levels.
Watering is essential for Chinese elm, but too much can be just as harmful as not enough. Water them when the compost is completely dry, but don’t water daily as this can lead to sodden soil and lack of vigour.
Elms are fairly resistant to pests, but aphids can be a problem. They can curl leaves and stems and leave sticky honeydew on them, which is why aphid predators are so important for your garden. You can also try using a soap solution to kill them or even use ladybugs, if you’re lucky enough to have them in your area.
