Bonsai is not a plant species but the art of growing a miniature tree in a shallow container so that it looks like a mature tree in nature. It sounds difficult, but anyone can start: the key is choosing the right first tree and learning a few basic rules.
Growing miniature trees in containers began in China (penjing) and developed into an art of its own in Japan. The word bonsai means “tray planting”. The oldest bonsai live for centuries and are passed down through generations.
Which tree to choose as a beginner
The golden rule: bonsai trees are either indoor or outdoor. Juniper, pine and maple are outdoor plants that need a cold winter rest; indoors they slowly decline. For the home, choose tropical and subtropical species.
Which tree to choose for your first bonsai and how to care for it
Ficus (for example Ficus microcarpa) is the most forgiving indoor bonsai.
Portulacaria is a succulent with fleshy leaves that tolerates occasional missed watering.
Carmona (Fukien tea) is beautiful but fussier: it dislikes drying out and temperature swings.
Chinese elm can grow indoors or outdoors and responds well to pruning.
Watering. Soil in a small pot dries fast. Water when the surface is slightly dry until water runs from the drainage holes, or dip the pot in water for a few minutes. Never let it dry out completely.
Light. Indoor bonsai need the brightest spot in the home; a grow light may help in winter.
Feeding. From spring to autumn, a weak liquid fertiliser every 2–4 weeks.
Pruning and pinching. Trim new shoots back to 1–2 pairs of leaves regularly to keep the canopy dense and compact.
Wiring. Shape branches with copper or aluminium wire and remove it before it cuts into the bark.
Repotting. Repot young trees every 2–3 years in spring, trimming the roots and refreshing the soil.
