The ficus Bonsai tree is an indoor tree that does not endure frosty conditions. It can be kept outside in the summer as long as temperatures are above 60°F (15°C). It requires a lot of light, preferably full sunlight, so be sure not to place it in a shady location. The temperature should be kept relatively constant. Figs can endure low humidity due to their thick, waxy leaves, but they prefer higher humidity and need extremely high humidity to develop aerial roots. The Ficus should be watered normally, which means it should be given water generously whenever the soil gets slightly dry. The Bonsai Ficus prefers room temperature soft water and it can tolerate occasional over, or underwatering. We advise daily misting to maintain humidity, but too much misting can create fungal problems. The warmer the placement of the fig during winter the more water it needs. If it’s kept in a cooler place it only needs to be kept slightly moist. Continue reading about watering Bonsai trees.
