When the soil is barely damp to the touch pour water evenly all over the soil surface until the water drains through into a tray or saucer. It is important to never let your bonsai dry out and avoid keeping it constantly wet.
For outdoor Bonsai we recommend using a relatively high Nitrogen content fertilizer like NPK 10:6:6. in spring, a more balanced fertilizer like NPK 6:6:6 is more optimal for summertime, and a low Nitrogen fertilizer like NPK 3:6:6 for autumn.
These plants need about 5 hours of direct or indirect sunlight a day. Some species do better in winter if they get their light from indirect sources. Something to keep in mind is that these plants can burn if they're taken from a shady place to a sunny position.
Try to keep a temperature between 12 and 30 degrees Celsius. Your Bonsai is a living tree. All trees need moisture to survive and grow. Too little water will dry out the leaves and if it persists for a long time, the juice stream will also dry out.
Add a thin layer of heavy grain soil first, like lava rock, grit, or akadama, which serves as a drainage layer. Next, add another thin layer of Bonsai soil. Place the tree back in its pot. Use the wires previously attached in step 9 to hold the tree in place.
