Choosing the right soil and fertiliser

The soil and fertiliser you use for your incense cedar bonsai tree will have a direct impact on its health and longevity. It is important to remember that bonsai soil is not actually soil, but a mix of materials. This mix should provide good drainage, aeration, and moisture retention.

Cedar bonsai trees are susceptible to root rot, so it is important to use a soil mix that drains well. You can use bonsai-specific soil, which is available at most garden centres or online. This soil is designed to provide good drainage and aeration while retaining moisture. You can also add inorganic materials like perlite, vermiculite, or lava rock to improve drainage. If your soil mix is drying out too quickly, you can add more Akadama clay to help retain moisture.

The type of fertiliser you use will also depend on the needs of your incense cedar bonsai. You can use either liquid or soil fertiliser. Fertiliser is typically added before or during the growing season to promote healthy growth and development. You can use a balanced, bonsai-specific fertiliser, or try organic or liquid fertilisers. If you're feeling creative, you can even make your own fertiliser using coffee or bananas.

Remember that the health of your bonsai tree should guide your choices. Keep track of your tree's progress and be prepared to adjust your soil mix and fertiliser routine as needed. With the proper care and attention, your incense cedar bonsai will thrive and become a cherished part of your collection.

Pruning and wiring branches

Pruning and wiring are essential steps in shaping and maintaining the health of your bonsai incense cedar. Here are some detailed guidelines for these processes:

Pruning Branches:

Pruning enhances the health and aesthetic appeal of your bonsai incense cedar, promoting growth and vitality. It is important to prune away any dead, dying, or diseased branches to prevent potential diseases and create space for fresh growth. Look for branches with brown or brittle foliage, irregular growth patterns, or branches that are overcrowded or crossing each other. You can prune smaller branches using pruning shears, which allow for precise cuts and are ideal for shaping. Medium-sized branches can be cut with loppers, which provide more leverage for thicker wood. For larger branches, a pruning saw is necessary. Remember to wear safety gear, such as gloves and eye protection, to avoid any injuries during the process.

The timing of pruning is also crucial. Spring pruning encourages new growth and allows you to shape the tree, while fall pruning helps remove any dead or damaged branches before winter. Adjust your pruning schedule according to your local climate and frost dates to prevent damage to new growth. Regular monitoring of your tree's health will help you find the optimal timing for your specific conditions.

Wiring Branches:

Wiring is a technique used to shape the branches and trunk of your bonsai incense cedar. Younger, more flexible twigs are easier to wire and can be done during the growing season. Older branches can be shaped with guy wires, which help hold the desired bends in place. When wiring, start by wrapping the trunk tightly with a self-adhesive bandage to protect the vascular system, then use heavy wire to bend the trunk into your desired shape. You may also need guy wires to hold the bends tight and in place, especially for creating curvilinear designs. It is important to note that you may need to rewire occasionally to maintain the desired shape, depending on the growth and the species of your tree.

Repotting and styling

To begin the process of repotting, choose a large pot, as incense cedars can get quite large. The pot should have well-drained soil, and it is recommended to use a mix of white pumice, red lava rock, and diatomaceous earth. Fertilizers can be added in spring and autumn to promote growth and increase frost resistance. Remember to prune the roots every couple of years, cutting off about one-third of their length.

When styling your incense cedar bonsai, aim to thicken the trunk. To do this, allow the branches to grow long, and keep them pruned tight and close to the trunk. This will help to bulk up the trunk using "sacrifice branches". Eventually, these "sacrifice branches" can be replaced with shorter, closer branches to refine the bonsai's shape. It is important to pay attention to inner growth and ensure that it receives adequate light. You can also use wiring techniques to shape the tree, but be careful not to damage the bark and cambium.

Additionally, it is recommended to protect the vascular system of the tree by using a double-layer wrap of self-adhesive bandage, such as 3M vetwrap. This provides support and can be combined with heavy copper wiring and guy wires to hold bends in place and guide the desired shape of the tree.

Remember to be mindful of potential pests and illnesses, such as caterpillars, bugs, and root white decay. Overall, with patience, dedication, and the right techniques, it is possible to successfully repot and style an incense cedar bonsai tree.

Dealing with pests and diseases

Incense cedars are usually pest-free. However, they can be attacked by aphids and the fungi Sirococcus and Pestalotia, which cause shoot blight and defoliation. To deal with these pests and diseases, use a specific pesticide and try to improve the growing conditions for your tree.

Root rot can also occur if the tree is overwatered. To prevent this, do not disturb the root system too much and only lightly prune the roots. During the growing season, water daily if necessary, but let the soil get dry before watering again. Be careful not to overwater, especially in winter, as this will increase the risk of frost damage to the roots.

To thicken the trunk, you will need to keep some branches pruned tight and close to the trunk. This will help to replace the long bare branches as you get closer to refining the bonsai. Use "sacrifice branches" to bulk up the trunk, and then replace those with the branches you kept short and close to the trunk. This is a basic technique for developing a Hinoki (Chamaecyparis obtusa), which has similar growth patterns to Calocedrus and Thuja.

Watering and humidity

Watering your incense cedar bonsai is critical to its health and growth. Incense cedars, like Calocedrus, are resilient trees that can withstand drought conditions, but proper watering is still essential for their well-being. Here are some detailed guidelines on watering and humidity to help you care for your incense cedar bonsai:

Watering Techniques and Frequency:

When it comes to watering your incense cedar bonsai, it is crucial to mimic the natural conditions in which cedars thrive. Cedars are native to regions with quite dry conditions and can suffer from root rot if overwatered. Therefore, it is essential to allow the soil to dry out between waterings. During the growing season, water your bonsai deeply and thoroughly, but only when the soil is dry. Be careful not to overwater, especially in winter, as this can increase the risk of frost damage to the roots.

Soil Moisture and Drainage:

Maintaining the right soil moisture level is critical for the health of your incense cedar bonsai. Ensure the soil drains well to prevent waterlogging, which can lead to root rot. Allow the top inch or two of the soil to dry out before watering again. If the soil remains constantly wet, it can cause more harm than good. Well-drained soil is essential to provide the roots with the oxygen they need and prevent root diseases.

Water Quality and Temperature:

Use water that is at room temperature or slightly warmer for your bonsai. Avoid using cold water, as it can cause temperature shock to the roots. If your tap water is highly chlorinated or has a high mineral content, consider using filtered or distilled water instead. The quality of the water is important to ensure the bonsai receives the right nutrients and avoids any potential damage to its delicate root system.

Humidity Considerations:

Incense cedars are adaptable trees that can tolerate a wide range of humidity levels. However, they grow best in environments with moderate to slightly higher humidity. If the air is too dry, it can affect the tree's ability to absorb water and nutrients. Consider using a humidity tray or pebble tray to increase the humidity around your bonsai, especially during hot and dry periods. Additionally, misting the foliage with water can help raise the humidity and keep the leaves healthy.

Watering Schedule and Monitoring:

Establish a regular watering schedule for your incense cedar bonsai, but remember that the frequency may vary depending on the season and the bonsai's specific needs. During the growing season, you may need to water daily if the soil dries out quickly, but always ensure you don't overwater. In winter, reduce watering, allowing the soil to remain on the drier side. Monitor the moisture level in the soil regularly by using a moisture meter or your finger. This will help you adjust your watering schedule as needed.

By following these guidelines on watering and humidity, you can ensure that your incense cedar bonsai stays healthy and thrives for years to come. Remember that proper watering is critical to the tree's well-being, and always pay attention to the soil moisture level to avoid overwatering or underwatering your delicate bonsai tree.
