How to Care for a Bonsai Tree | Bonsai Care Tips for Beginners & Enthusiasts
Caring for a bonsai tree requires patience, attention, and an understanding of its unique needs. From proper watering techniques to pruning and soil maintenance, every step plays a crucial role in keeping your bonsai healthy and thriving. If you’re looking for a detailed guide on how to care for a bonsai tree, this in-depth breakdown will help you ensure your tree stays in the best condition.
Watering Your Bonsai Tree
One of the most important aspects of caring for a bonsai is maintaining the right moisture level in the soil. Bonsai trees are grown in small pots, meaning they dry out much faster than regular houseplants. You should check the soil at least twice a day, preferably in the morning and evening. Please ensure it remains slightly damp to the touch at all times.
✔ Never let the soil dry out completely!
✔ Avoid overwatering as this can lead to root rot, the soil should be damp but not waterlogged.
✔ Different species have different preferences. For example, the Fukien Tea Tree and Serissa bonsai like to be kept slightly on the drier side of damp.
How to Water Your Bonsai Tree Properly
When watering, do so gently but thoroughly until water drains from the bottom of the pot. This ensures that the entire root system receives sufficient water. If your bonsai’s soil has dried out too much, submerge the pot in water for a few minutes to allow it to soak up moisture evenly.
Bonsai soil should be kept damp to the touch at all times; varieties such as the Oriental Tea Tree and Serissa like to be kept on the drier side of damp. You should check the soil multiple times a day, we usually say morning and evening to get yourself into the routine. You should also feed your bonsai once a week with a bonsai feed/fertiliser.
The leaves should be misted regularly to increase the humidity. You can mist with plain water, or our bonsai mist which helps to condition the leaves and deter pests.
Feeding & Fertilising Your Bonsai Tree
Regular feeding is essential for maintaining strong, healthy growth. Since bonsai trees are potted in limited soil, they rely on fertiliser for essential nutrients.
✔ Use a bonsai-specific fertiliser once a week.
✔ Indoor bonsai should be fed all year round
✔ Outdoor bonsai should be fed during growing season (March – October).
✔ Avoid using standard plant food, as bonsai fertilisers are specially formulated to provide the right balance of nutrients.
Humidity & Misting for Bonsai Care
Bonsai trees benefit from increased humidity, especially if they are kept indoors. Dry air from heating or air conditioning can cause leaf drop and stress the tree.
– Misting the leaves regularly helps maintain humidity levels and keeps the foliage fresh.
– You can mist with plain water or use our specialised bonsai mist that conditions the leaves while deterring pests.
– Placing a humidity tray filled with water beneath your bonsai can also help maintain moisture in the air.
Pruning & Shaping Your Bonsai
Pruning is a key part of bonsai care. It not only maintains the tree’s miniature shape but also encourages new growth and strengthens the canopy.
– If you notice dead or weak branches, trim them back to where they are still alive. This helps redirect energy to healthy areas and promotes back budding.
– Trim back straggly shoots when they start to extend beyond the tree’s natural shape.
– The foliage should be pruned so that the “pads” remain well-defined and neat.
– Use bonsai scissors to carefully remove excess growth without damaging the tree.
Weeding & Moss Control
Regular maintenance of the soil surface is crucial to ensure your bonsai gets the nutrients and moisture it needs.
✔ Use a spatula or blunt knife to gently remove excess moss. Top up the soil if needed with high-quality, well-draining bonsai soil.
✔ Remove weeds as soon as they appear, either by hand or using a tweezer tool.
✔ Scrape away moss and algae buildup on the soil surface, as these can prevent water from reaching the roots properly.
Repotting & Root Care
Over time, your bonsai will outgrow its pot, and the roots will become compacted. Repotting is essential to refresh the soil and keep the tree healthy.
– Most bonsai trees need repotting every 2–3 years, but fast-growing species may need it more often.
– The best time to repot can depend on whether your bonsai lives indoors or outdoors.
– Trim back excess roots carefully to maintain a balanced root system.
