Will my indoor bonsai drop its leaves in winter?
Most indoor bonsai will drop some of their leaves during winter. This is because of the temperature change, and some bonsai will drop more leaves than others. You may find that the leaves turn yellow (but not crispy) and drop. This is completely normal and nothing to worry about. During winter, it is important to remember that the bonsai will not be growing as fast as they would during summer, so it may take a while before you see the new growth coming through. This will also mean that the bonsai will need less water during colder months, so donât donât be worried if you feel you arenât watering your bonsai very much!.
Will my outdoor bonsai drop its leaves in the winter?
If your bonsai is evergreen, then it wonât loose its leaves in the winter, which means you should have a lovely canopy all year round!.
If you have a deciduous variety of bonsai, then the bonsai will drop all of its leaves over winter. This is a wonderful time to admire and truly appreciate the trunk and branch structure of your bonsai.

FAQ
Do bonsai trees lose leaves?
Typical outdoor Bonsai species include the Juniper, Pines, Maples and Elms. Juniper trees stay green all year, but elm trees lose their leaves (or at least part of them) in the fall and winter. If you think your tree is losing leaves because of a problem and not because of the season, here’s what you should check:
Do bonsai trees shed their leaves in winter?
While some deciduous bonsai trees do shed their leaves in winter as part of their natural cycle, not all species follow the same pattern. Evergreen varieties like junipers or pines will typically keep their foliage intact throughout the cold months, while other varieties will shed their leaves just as they would if grown to full size outdoors.
Can a bonsai tree survive winter?
If winters are cool enough, you can grow species like Trident maples (Acer Buergerianum) and Japanese maple that can through winter dormancy. Once you know if your Bonsai Tree should be kept inside or outside, it will be easy to figure out why its leaves are falling off.
Do bonsai trees turn yellow in the fall?
If your bonsai is a deciduous tree such as maple or elm, it will naturally turn yellow in the fall. The leaves look yellowish, and eventually, they will dry. Many evergreen bonsai do not shed all their leaves. But their leaves can still turn yellow. Then, the older leaves will fall off in the fall. But the bonsai will become green again in spring.
Why do bonsai trees go dormant?
One reason is the natural response of certain species to changes in temperature and daylight hours. Just like their full-sized relatives in nature, bonsai trees go through a dormant period during winter where they conserve energy by shedding leaves, even if they spend most of their time indoors.
Do bonsai drop leaves?
Indoor Bonsai should be kept above 60°F (15°C) throughout the year, meaning that in most climates they need to be kept indoors during winter time. Most indoor Bonsai species (Ficus, Jade, Carmona, etc) do not drop their leaves, unless there is a problem:
