Fertilizing
Feed your Ligustrum bonsai every two weeks during the growing season (spring and summer) using either a balanced chemical fertilizer diluted to half strength or organic liquid fertilizer. During winter, reduce fertilizing to once per month. For best results, always apply fertilizer to moist soil to ensure proper nutrient absorption and distribution throughout the root system. Begin fertilizing when you notice new growth appearing on the tree, as this indicates the start of the active growing period.
The regular fertilization schedule helps promote healthy growth, vibrant foliage, and increased resistance to pests and diseases. This consistent feeding routine provides the essential nutrients needed for the tree's vigorous growth pattern and helps maintain its overall health and vitality throughout the seasons.
Placement
Ligustrum bonsai can thrive in both full sun and partial shade conditions, making them quite versatile. However, temperature management is crucial - bring them indoors when temperatures drop below 40°F (4°C). They can be successfully grown both indoors and outdoors, but prefer to be placed outside during favorable weather conditions to benefit from natural sunlight. When kept indoors, ensure they receive bright, indirect light and maintain adequate humidity levels.
For optimal growth and flowering, place the tree where it will receive full morning sun but some protection from intense afternoon heat. This balance helps prevent leaf scorch while providing enough light for robust growth and flower production. Consider rotating the tree periodically to ensure even growth on all sides.
Pruning
Ligustrum responds extremely well to pruning and requires regular attention due to its fast growth rate. Prune in early spring before new growth emerges, focusing on maintaining the desired shape and removing any dead or crossing branches. When dealing with new growth, which can produce up to 7 or more leaf clusters at once, trim back to leave only two leaves on each new growth cluster. This technique helps maintain the tree's compact form and encourages dense branching.
Remove all suckers growing near the base of the tree as they divert nutrients from the upper branches. The tree's bark is sensitive yet flexible, making it ideal for wiring and shaping, but exercise caution to avoid damage. Wire shaping should be done in late spring, and thanks to the tree's rapid growth rate, any minor bark damage from wiring typically heals quickly.
Repotting
Repot your Ligustrum bonsai annually due to its vigorous root system and fast growth rate. The best time for repotting is early spring before new growth begins. The roots can be pruned back aggressively every 2-3 years as Ligustrum tolerates root pruning well. Use a well-draining soil mix consisting of 60% aggregate (pumice or clay pellets) and 40% organic matter (compost soil).
During repotting, carefully inspect the roots and remove any rotted or circling roots. This regular maintenance helps maintain the tree's health and prevents it from becoming root-bound, which could impede growth and nutrient uptake.
Watering
While Ligustrum is relatively hardy, proper watering is essential. Water regularly during summer to prevent the soil from drying out completely, but avoid overwatering as they are susceptible to root rot. During hot periods, you may need to water twice daily. Check moisture levels by inserting your finger into the top inch of soil - if it feels dry, it's time to water.
Use room temperature water and ensure thorough drainage after each watering session. Maintain consistent moisture levels without allowing the soil to become waterlogged. During winter months, reduce watering frequency but continue monitoring soil moisture levels to prevent either over or under-watering.
