Lime

Fertilizing

During the growing season, feed your lime bonsai every two weeks with a balanced fertilizer. In mid-summer, reduce to half-strength to avoid encouraging overly large leaves. Organic options like compost tea or fish emulsion can provide additional nutrients and promote healthy growth. Remember that over-fertilizing will result in large leaves that can throw off the tree's proportions, so err on the side of less rather than more.

Placement

Place your lime bonsai in full sun to partial shade outdoors. This species is remarkably hardy and can handle frost without winter protection. For optimal growth and flowering, ensure good air circulation around the tree. If grown indoors temporarily, place near a bright window that receives plenty of indirect light and maintains temperatures between 60-80°F (15-27°C).

Pruning

The art of pruning lime bonsai requires careful timing and technique. Begin major structural pruning in early spring before new growth emerges, focusing on removing dead, damaged, or crossing branches to improve airflow and aesthetics. Save secondary pruning for mid-summer, when larger leaves should be trimmed to encourage smaller foliage development. This two-phase approach helps maintain the tree's desired shape while promoting healthy growth patterns. For branch development, use selective pruning to create proper hierarchy and maintain proportions. Always use clean, sharp tools and seal large cuts to prevent disease.

Repotting

Repot your lime bonsai every 2-3 years in early spring, though never wait longer than 5 years between repottings. When repotting, use a well-draining soil mix with a slightly acidic to neutral pH (5-6). Be conservative with root pruning - remove no more than 20-30% of the root mass to maintain tree health. Choose a pot that complements the tree's size and style while ensuring adequate drainage. After repotting, place the tree in a sheltered location for several weeks to recover, and maintain consistent moisture without overwatering.

Watering

During summer months, lime bonsai appreciate generous watering to maintain consistent soil moisture without becoming waterlogged. Water thoroughly when the top inch of soil feels slightly dry to the touch, allowing excess water to drain freely. Reduce watering frequency in spring and autumn, and keep the soil just moist during winter dormancy. Consider the tree's environment, pot size, and weather conditions when establishing a watering routine. Regular misting can help maintain humidity, particularly after repotting or during dry periods.
