Before we start reviving your Cotoneaster bonsai tree, we need to take a look at the common causes of browning leaves. 

Cotoneaster trees are a deciduous plant with dark green leaves that turn yellow, red, and orange during the autumn season. With adequate care, your bonsai should remain beautiful and healthy for many years. The beauty of Cotoneaster bonsai increases as your tree matures.

Over-watering Causing Browning Leaves in Cotoneaster Bonsai

Most beginners in bonsai tree cultivation make the colossal mistake of over-watering. In some cases, individuals tend to think that a lot of water is essential in the healthy growth of bonsai trees. Yes, your bonsai tree needs water, but not excessive amounts.

Why does over-watering cause browning leaves in Cotoneaster bonsai? Well, the water gets trapped, thereby leading to the rotting of the roots. You have probably learned by now that you need a healthy root system when it comes to bonsai tree cultivation.

When the roots start rotting, your cotoneaster bonsai will begin to wilt and eventually die if something is not done. The browning of the leaves is among the first indications of a dying tree. Not enough water and nutrients are getting to your steam and leaves due to the rotting roots.

Under-watering Causing Browning Leaves in Cotoneaster Bonsai

Under-watering will also result in browning of your Cotoneaster bonsai leaves. This scenario usually happens when individuals forget to water their trees over prolonged periods. You should not let your Cotoneaster bonsai soil dry out for extended periods.

You need to evaluate your bonsai tree’s water requirement and adjust the watering schedule appropriately. Take your time to determine how often your Cotoneaster bonsai needs watering and the amount of water required.

Lack of sufficient water will lead to a dried-up trunk and browning of the leaves. Ensure that you monitor the water requirement of your Cotoneaster bonsai to help you make a consistent watering schedule. Understand that a watering schedule that works for another individual might not work for you.

Low Light Causing Browning Leaves in Cotoneaster Bonsai

Bonsai trees need sufficient light, just like all other trees. The fact that you have your bonsai tree indoors does not mean that you shouldn’t provide enough light. Browning of Cotoneaster bonsai leaves will start when there is insufficient sunlight.

Morning sunlight and afternoon shade are the ideal conditions for your Cotoneaster bonsai during the spring, fall, and summer. Place your Cotoneaster bonsai on a bench or table to ensure that it receives a sufficient amount of sunlight.

Low light will cause browning leaves in Cotoneaster bonsai within a short period. Most people have the wrong notion that indoor plants don’t need direct sunlight. The Cotoneaster bonsai particularly needs a lot of sunlight, especially during summer and spring.
