Caring for an outdoor Bonsai tree is different from that of normal potted plants. The main reason is that Bonsai trees are planted in small pots and therefore have limited storage for nutrients and water. More important is that Bonsai trees from temperate climates need their period of winter dormancy, but most species need some protection from frost and strong winds during that time.

Specific care of outdoor Bonsai species:

1. Light
Most outdoor Bonsai trees need sunlight for at least a few hours a day. Their internodes and leaves will grow too large otherwise and they get prone to pests and diseases then. Most conifers should be placed in full sun for healthy growth.

2. Humidity
On hot days and in a paved place surrounded by walls the trees can suffer from low humidity. You can increase humidity near your Bonsai tree by placing it on a humidity tray filled with water and by misting your tree a few times a day. What also helps is to wet the shelves, floors and walls around the trees.

3. Watering and fertilizing
The most important rule is; never water on a routine. Monitor your tree and only water when needed. This can be once in three days or several times a day, depending on the weather, species and size. Please read the Bonsai watering and Fertilizing pages for more detailed information.

4. Temperature
Outdoor trees can endure high temperatures as well as very cold weather if they are cared for properly. It is important for most species to provide protection from strong frost in winter. In spring, when the new leaves emerge, take care that the trees are protected even from light night frost.

To summarize, make sure to select the right tree species and take into account the specific care guidelines for outdoor trees, and you will do just fine!
