A caring for a bonsai tree may seem complicated, but with the right knowledge and attention, anyone can learn it. In this blog, you’ll read how to care for a bonsai tree: from watering to the right placement, feeding, and pruning.
What exactly is a bonsai tree?
A bonsai tree is not a separate plant species, but a regular tree or shrub kept in miniature form. Through pruning, wiring, and special pots, the tree stays small while retaining the look of a mature tree.
Watering a bonsai tree: how often and how much?
One of the most important parts of bonsai care is watering. Many beginner bonsai enthusiasts wonder: how often should you water a bonsai? The answer depends on several factors.
Check the soil
Insert your finger about two centimetres into the soil. Does it feel dry? Then it’s time to water. Preferably use a bonsai watering can with a fine rose to moisten the soil evenly.
Frequency
-
In summer, it may be necessary to water daily, especially with small pots or high temperatures.
-
In winter, once or twice a week is often sufficient, depending on humidity and temperature.
Extra tip
Use rainwater or low-lime water. This prevents a build-up of salts and promotes a healthy soil structure.
Indoor bonsai care: where should you place your little tree?
Many bonsai trees are kept indoors, but not every species is suitable for that. Tropical species such as Ficus or Carmona do well indoors.
Light and temperature
Place your bonsai preferably close to a window with plenty of daylight, but avoid harsh midday sun. A constant temperature between 15 and 25 °C is ideal.
Humidity
Indoors, the air is often too dry, especially in winter. You can solve this by placing a small dish of water next to your bonsai or using a humidifier.
bonsai tree care: pruning and shaping
Pruning and shaping are essential to keep your bonsai tree both healthy and attractive. Follow the step-by-step plan below to do this correctly:
-
Check your bonsai regularly
Check the tree weekly for new shoots, dead twigs, or abnormal growth. -
Prune back young shoots
Cut back new shoots to two to three pairs of leaves to keep the shape compact. -
Remove diseased or dead twigs
This helps prevent disease and keeps the tree vigorous. -
Choose the right wire for shaping
Use special bonsai wire or copper wire that is about one third of the branch thickness. -
Wrap the wire and bend carefully
Wrap the wire around the branch at a 45-degree angle and slowly bend it in the desired direction. -
Check the wire regularly
Make sure the wire doesn’t cut into the bark. Remove it in time, usually after a few weeks to a few months. -
Repeat if necessary
Shaping is a process. Sometimes a second wiring is needed if the branch springs back.
Fertiliser: what does a bonsai need?
A bonsai needs regular fertiliser, especially because it grows in a small amount of soil. Use a special bonsai fertiliser, preferably liquid.
Fertilising schedule
-
In spring and summer: every two weeks.
-
In autumn: once a month.
-
In winter: only if the tree is actively growing (for tropical species).
Repotting bonsai: why and when?
It’s necessary to repot your bonsai every two to three years. This helps prevent root rot and refreshes the nutrient-rich soil.
How do you repot a bonsai?
-
Carefully remove the tree from the pot.
-
Prune the roots back slightly.
-
Replace the old soil with fresh bonsai soil with good drainage.
-
Put the tree back and water generously.
