During the growing season (spring and summer), apply a balanced, slow-release fertilizer once a month. Alternatively, use a liquid fertilizer every two weeks. Higher nitrogen content is beneficial in spring for promoting lush foliage, while a balanced or slightly higher phosphorus fertilizer in late summer encourages flowering. Avoid fertilizing during winter dormancy to prevent root burn. These vital nutrients help maintain healthy foliage and support the tree's vigorous growth patterns throughout the season.
The ideal location provides full sun to partial shade, with at least six hours of direct sunlight daily. During hot summers, especially in warmer climates, provide afternoon shade to prevent leaf scorch and dehydration. While Lonicera species are generally hardy, they need protection from harsh winter conditions in colder regions - place them in a sheltered spot or unheated greenhouse. For indoor placement, a south-facing window works well, ensuring the tree maintains a temperature between 60-75°F (15-24°C). Keep the tree away from heaters and air conditioners that can create drafts.
Pruning is crucial for maintaining shape and encouraging dense foliage, with the best time being early spring before new growth begins. Regularly trim back new shoots to control size and shape, and remove dead or weak branches to improve air circulation. When pruning, cut back to one pair of leaves to encourage dense foliage. For flowering, allow the bonsai to grow until flower buds develop. Being a resistant plant, honeysuckle will grow back even if cut to the wood. When styling, avoid straight lines and instead follow the natural curve of the branches, letting them grow at a 30-degree angle.
Repot every two to three years in early spring before new growth starts. Use a well-draining bonsai soil mix combining akadama, pumice, and lava rock. When repotting, trim about one-third of the root mass to encourage healthy new growth and ensure the tree fits properly in its container. Choose a pot at least 10 inches wide and 6-8 inches deep. After repotting, keep the tree in a shaded area for a few weeks to allow the roots to recover, and water thoroughly to help establish the root system.
Water thoroughly when the top layer of soil feels dry, ensuring excess water drains well from the pot. During the growing season (spring and summer), increase watering frequency, especially in hot weather. Use a gentle spray to avoid disturbing the soil and continue until water runs out of the drainage holes. While honeysuckle prefers consistently moist soil, it's sensitive to waterlogging, so ensure good drainage. In winter, reduce watering but never allow the soil to completely dry out. High humidity benefits the tree, so consider misting regularly or using a humidity tray with pebbles.
