Where to Keep Your Boxwood Bonsai
Boxwood bonsai can be kept both indoors and outdoors, depending on the season and climate:
- Outdoors: During the warmer months, place your bonsai in a partially shaded or sunny spot, ensuring it is shielded from the harsh midday sun. While Boxwood is hardy, it should be protected from frost and freezing temperatures.
- Indoors: In winter, bring your bonsai indoors to a well-lit location, such as a south-facing windowsill. Aim for 6 hours of indirect sunlight daily, and keep it away from draughts, radiators, or heat sources that could cause stress.
Watering Your Boxwood Bonsai
Watering correctly is critical for keeping your Boxwood bonsai healthy. Follow these tips:
- Water when the top inch of soil feels dry.
- Use a fine-spouted watering can to evenly moisten the soil without waterlogging.
- Avoid letting the soil completely dry out, especially in summer, but ensure excess water can drain away to prevent root rot.
During winter, reduce watering as the bonsai’s growth slows, but don’t allow the soil to dry out entirely.
Soil and Repotting
A well-draining bonsai soil mix is key to healthy growth. Use a blend of akadama, organic matter, and sand to retain moisture while preventing water from pooling at the roots.
Repot your Boxwood bonsai every 2-3 years in early spring to refresh the soil and check root health. Trim the roots slightly during repotting to encourage balanced growth and maintain the plant’s compact size.
Pruning and Shaping
Boxwood bonsai are highly versatile and can be pruned into intricate shapes:
- Trim back new shoots regularly to maintain your desired shape and promote dense foliage.
- Perform heavy pruning in early spring or late summer to encourage healthy growth.
- Use wiring to train branches into shape, but remove wires promptly to avoid scarring the bark.
Feeding Your Bonsai
Feed your Boxwood bonsai with a balanced bonsai fertiliser to support its growth:
- During the growing season (spring to early autumn), fertilise every 2-4 weeks.
- Reduce feeding to once a month in winter or stop altogether if the bonsai becomes dormant.
Humidity and Temperature
Boxwood bonsai thrive in moderate humidity levels:
- Place a humidity tray filled with pebbles under the pot to increase moisture in the air, especially indoors.
- Protect the bonsai from frost and extreme heat, as these can harm its health.
Common Pests and Problems
Boxwood bonsai are hardy but may encounter some common issues:
- Boxwood Leaf Miners: Yellow or blotchy leaves may indicate an infestation. Treat with neem oil or an eco-friendly pest spray.
- Spider Mites: These pests thrive in dry conditions. Increase humidity and spray the leaves with water to dislodge them.
Avoid root rot by ensuring your bonsai’s soil drains properly and avoid overwatering.
