Juniper bonsai trees are the most popular bonsai specimens among coniferous trees. In fact, all varieties of coniferous trees can be used to create beautiful looking bonsai specimens. Almost fifty different varieties of juniper bonsai can be found around the world. Since they are one of the easiest varieties of bonsais to grow, they are very popular especially among bonsai cultivators who are just beginning to learn the art.
You can grow juniper bonsai trees indoors as well as outdoors. But when you grow them indoors, you should take care to provide sufficient light and humidity. Given a choice, you should choose to grow them outdoors because that is where they would really thrive.
Juniper bonsai trees are often referred to as Chinese Junipers. The Needle Juniper is another species that is quite popular. It has foliage that are like sharply pointed needles. In fact most junipers have needle-like foliage during the early stages of life. As the plant matures, the foliage changes to scale-like foliage. The colors of the foliage range from light greens to blue-greens. Some junipers even have silver and gold hues in their foliage.
Juniper bonsai trees need to be watered regularly. You can feel the soil to determine whether it is time to water the plant. You need to stick a finger about an inch into the soil to check whether the soil is dry. If it is dry, you need to water the plant immediately. You can water the plant in two ways. The best way to water, the plant is to set the pot inside a water container for about 15 to 30 minutes. The water should almost reach the rim of the pot. Then the water should be allowed to drain completely since junipers are vulnerable to root rot. Another way to water the plant is to pour water from the top and wait for a few minutes before pouring some more water again. You should ensure that the pot is neither saturated with water nor is completely dry.
In order to let the foliage breathe freely, you need to keep it free of dust by sprinkling water on the foliage. This process is also known as misting. Especially when you repot the plant, you need to do this often. Until the roots recover sufficiently to absorb the required amount of water to sustain the plant, you need to keep the plant from dehydrating by sprinkling water on the foliage. Since Juniper bonsai trees can absorb water through the foliage, this would be a good way to keep the plant supplied with sufficient water. You can minimize water loss and excess transpiration through misting.
You need to allow adequate sunlight to reach your Juniper bonsai trees. You can place them fully to low intensity morning sunlight. But after the sun comes up fully, and during the afternoon hours, you can keep them under a shade. Or you can expose the plant to sunlight throughout the day as long as it filters down through a shade before reaching the plant.
You can keep the pot on a humidity tray which can simply be a plate filled with stones and some water. The tray can also collect the water that drains out when you water the pot. You also need fertilize your Juniper bonsai trees every 2 or 3 weeks, especially during the initial growing years. You should use high a nitrogen fertilizer during spring, a balanced fertilizer during summer and fall, and a low nitrogen fertilizer during winter.
