To assist you in troubleshooting, we have prepared this quick guide to help you determine the issue and find a suitable solution. We hope the following helps answer ‘What is wrong with my bonsai?’ and provide accurate and useful bonsai help.

Dry & Crispy Leaves
The bonsai has become too hot or the soil too dry at some point.
Soak well, then allow to drain. Keep the soil just damp to the touch going forward. Mist the leaves daily with water.
This happens quite quickly, over the course of a few hours or a couple of days.

Old Leaves
Brown spots on old leaves are nothing to worry about.
You can remove the old leaves if you prefer but they will drop off naturally in time. They will be replaced in Spring with vibrant, lush new leaves. If you find many old leaves are dropping be cautious not to over water the bonsai, as it will not be transpiring as quickly as before.

Dark Black Spots on New Leaves
Dark black spots on both old and new leaves is an indication of Black Spot. Treat with a fungicide which treat Black Spot such as Roseclear.
Ensure you repeat spray, at least twice, to make sure that the problem has been irradiated. It is also very good practice to spray your bonsai with a combined insecticide/fungicide monthly as a preventative measure – to keep your bonsai free from pests & disease.

Yellowing of Leaves
Yellowing of leaves can be evidence of a nutrient deficiency. Your bonsai may be low on nitrogen, magnesium or potassium.
Feed regularly with Bonsai Fertiliser & spray with a Foliar Feed Mist.

Black Tips to the Leaves
Black/brown tips to the leaves is an indication that your bonsai has been over-watered & that the roots have begun to rot. Recovery is a slow process as the roots need to re-grow before the leaves can re-grow. Move to a semi-shaded position and keep the soil very slightly damp and not wet. Sometimes you will also notice that the trunk wobbles in the pot. This is a direct result of root rot.

Sticky Leaves and White Skin Casts
Sticky leaves and white particles is an indication that your bonsai is suffering from a pest. This is usually aphid – greenfly or black fly.
You will be able to see them if you look on the underside of the leaves. Treat with a general insecticide ensuring you spray on top & underneath the leaves, on the trunk & branches.
Repeat the spray according to the instructions at least twice.

Bonsai Not Growing & Solid Root Ball
If your bonsai has not been actively growing for a while & the root ball is solid, then your bonsai tree has become ‘pot bound’.
The leaves will also start to deteriorate.
Repot your bonsai into a larger pot with fresh soil or root prune
(remove only about 15% of the root ball) & put back in the existing pot, if large enough, with fresh soil around the edge. If you are worried send a photo to help@bonsaidirect.co.uk and we can advise you if your bonsai is strong enough & what time of year to do this.

Dead Appearance with No Leaves
If your bonsai has no leaves and appears to be dead, check first.
Make some small nicks in the trunk and branches.
If the cambium layer beneath the bark is brown, then we regret the bonsai has died. This could have been a watering issue.
If the layer beneath the bark is green, this is good news. Keep the soil damp and not wet to the touch. Position the bonsai somewhere with good daylight but not too hot & mist the branches twice daily with water.
If the layer is white, then you have cut too deep so kindly try again.

Spindly, Leggy, Yellowing Shoots
If the shoots on your bonsai are leggy and the leaves yellowing, this is indicative of insufficient light. Move your bonsai to a brighter position, prune back any straggly shoots and feed weekly with Bonsai Fertiliser.
You may find that this is only happening on one side of the bonsai, so regular turning of your tree is beneficial. This is so that all the leaves can photosynthesise properly and receive even daylight.

Wilting Leaves
This is a hard one to identify as there can be several causes.

• – The bonsai may have dried out or become too hot. In this case soak the soil well, then allow to drain. Keep the soil just damp to the touch going forward. Mist the leaves daily with water. The symptoms are usually quite quick.

• If the wilting is much slower (over the course of weeks) and the soil has not dried out then roots may be suffering from root rot. Recovery is a slow process as the roots need to re-grow before the leaves can re-grow. Move to a semi-shaded position and keep the soil very slightly damp and not wet.

• Wilting can also be a result of the bonsai becoming too cold. You may also notice a blackening of the leaves. Some species such as the Fukien Tea Tree like a warm position away from draughts, so try moving your bonsai to a warmer position.

Creating an Optimal Environment for Your Bonsai:
Guide to Bonsai Help – Essential Tips and Techniques

Assessing Lighting Conditions for Your Bonsai

Proper lighting is crucial for the growth and vitality of your bonsai tree. Consider the following factors to ensure optimal lighting conditions:

Evaluate Sunlight Exposure: Bonsai trees thrive in good natural daylight, but direct sunlight during mid-summer can be harmful. Find a suitable location that provides adequate sunlight without subjecting the tree to intense heat. Monitor the positioning of your bonsai to maximize light exposure while protecting it from scorching rays.

Check Watering Practices to Maintain Balance

Watering is a critical aspect of bonsai care. Follow these guidelines to maintain proper hydration:

Assess Soil Moisture: Use your finger to gently check the moisture level of the soil. It should be damp but not excessively wet or dry. Adjust your watering frequency accordingly to prevent overwatering or underwatering.

Ensure Proper Drainage: Adequate drainage is essential to prevent waterlogging and root rot. Ensure your bonsai pot has sufficient drainage holes and is not sitting in water. This allows excess water to escape and promotes a healthy root system.

Monitoring Humidity Levels for Bonsai Health

Humidity plays a significant role in the well-being of certain bonsai species. Consider the following to maintain optimal humidity:

Increase Humidity: If your bonsai shows signs of dryness, such as brittle leaves or excessive drying, you can enhance humidity levels around the tree. Utilize a humidity tray, mist the foliage regularly, or position the bonsai in a more humid area of your home, such as a bathroom.

Evaluating Fertilisation for Nutrient Balance

Proper fertilisation ensures your bonsai receives essential nutrients for healthy growth. Consider these aspects when fertilizing:

Select Suitable Fertiliser: Choose a high-quality bonsai-specific fertilizer that meets the nutritional needs of your tree. Bonsai Direct liquid fertiliser is recommended for its balanced formulation and suitability for various bonsai species. Follow the recommended dosage and frequency guidelines for optimal results.

Pruning and Maintenance for Bonsai Care

Regular pruning and maintenance are vital for shaping and preserving the health of your bonsai. Follow these steps:

Monitor Tree Health: Inspect your bonsai regularly for signs of disease, pests, or dead branches. Remove any unhealthy or unwanted growth to maintain the overall vigour and aesthetics of the tree.

By following these guidelines, you can ensure your bonsai receives the proper care and attention it needs to thrive and flourish in your care.
