Placement

Japanese Maple Bonsai do really well in sunny andairy locations, but when temperatures rise to 85 °F (30 °C) or above, it shouldbe placed somewhere with indirect sunlight to prevent the sun from damaging theleaves. The Japanese Maple is frost hardy, even when trained as a Bonsai, butwhen temperatures drop below 15 °F (-10 °C), it should be protected, forexample by being placed in a coldframe.

Watering

A Japanese Maple Bonsai must be watereddaily during the growing season. During the hotter days in the growing season,it's sometimes necessary to water your tree several times, if the soil iswell-drained and the tree is healthy and vigorous. As with all Bonsai, make sure to water on observation and not on a fixed schedule; the soil should neverdry out completely. Avoid watering with calcareous water as the Japanese Mapleprefers a neutral or slightly acid pH-value.
