What should I do when my bonsai tree's leaves turn yellow?
Last Updated: 03/28/2011
When the leaves turn yellow, it is usually a sign of lack of water absorption to the roots. The first thing to do is to increase the amount of water to at least a mug size amount everyday and it is best to do so in the early mornings like our nursery personnel does. If the water runs through the bottom too quickly or run-off the top soil, then it is time to aerate or till the soil. Aerate the soil by softening it with a fork or soil rake.

For some local conditions with low humidity, watering may be required twice a day; once in the morning and once at night. You can also try sink soaking for about 15-20 minutes. If you notice that its condition still worsens after a few weeks then repotting it with new soil would be necessary.

As for lighting, it needs at least filtered sunlight to keep the leaves green and also for new growth to occur. Please be careful with the use of A/C indoors since it will dry out the air and also cause the leaves to die.

We also recommend consulting the care instructions specific to your bonsai tree.
