Fertilizing

Hawthorn bonsai require regular fertilization to stay healthy and produce vibrant flowers and berries. During the growing season (spring to late summer), use a balanced, slow-release bonsai fertilizer every 2-4 weeks. This provides essential nutrients like nitrogen, phosphorus, and potassium for strong growth and flowering. Avoid over-fertilizing, as it can lead to excessive foliage at the expense of blooms and berries.

In autumn, reduce fertilization as the tree prepares for dormancy. Stop feeding entirely during winter to allow the tree to rest. A well-timed fertilizing schedule ensures your hawthorn bonsai remains vigorous and visually stunning throughout the year.

Placement

Proper placement is key to the success of your hawthorn bonsai. These trees thrive in full sun to partial shade, requiring at least 4-6 hours of direct sunlight daily. Insufficient light can reduce flowering and berry production, so choose a bright spot for your tree.

During summer, protect your hawthorn bonsai from extreme heat by providing light shade during the hottest part of the day. In winter, shield it from harsh frosts, as prolonged freezing temperatures can damage the tree. A cool, well-ventilated space is ideal for dormancy.

Whether indoors or outdoors, ensure your hawthorn bonsai is placed in a location with good airflow to prevent fungal diseases and promote overall health.

Pruning

Pruning is essential for shaping and maintaining your hawthorn bonsai. Perform structural pruning in late winter or early spring while the tree is dormant. This encourages new growth and helps maintain the desired form.

Throughout the growing season, conduct maintenance pruning to remove unwanted shoots and maintain the tree's shape. After flowering, prune back shoots to promote berry production and improve airflow, which helps prevent disease.

Always use sharp, clean tools to make precise cuts and minimize stress on the tree. Regular pruning not only enhances the tree's appearance but also supports its long-term health.

Repotting

Repotting is crucial for maintaining the health of your hawthorn bonsai. Repot every 2-3 years in early spring before new growth begins. This refreshes the soil and prevents root binding.

Use a well-draining soil mix, such as akadama, pumice, and lava rock, to ensure proper root health. During repotting, trim back the roots moderately, removing any dead or overly long roots. Avoid over-pruning, as this can stress the tree.

After repotting, water thoroughly and place the tree in a shaded area for a few weeks to allow it to recover. Proper repotting ensures your hawthorn bonsai has the space and nutrients it needs to thrive.

Watering

Watering is a critical aspect of hawthorn bonsai care. These trees prefer consistent moisture but are sensitive to waterlogged conditions. Water thoroughly when the top inch of soil feels dry, ensuring excess water drains freely from the pot.

Adjust the watering frequency based on the season, climate, and pot size. During the growing season, the tree may require more frequent watering, while in winter, reduce watering to match the tree's reduced needs.

Avoid letting the soil dry out completely, as this can stress the tree. Good air circulation and proper drainage are essential to prevent root rot and fungal issues. Consistent, mindful watering will keep your hawthorn bonsai healthy and vibrant.

By following these care guidelines, your hawthorn bonsai will thrive, producing beautiful flowers and berries while maintaining its elegant form.
