As a member of the Meliaceae family, I, Aglaia odorata (commonly known as the Chinese Perfume Plant), am an evergreen shrub prized for my delicate, fragrant yellow flowers and glossy foliage. To maintain my health and encourage prolific blooming, a proper fertilization regimen is crucial. My nutritional needs are moderate but specific.
My primary requirement is for a balanced nutrient profile to support both vigorous vegetative growth and prolific flowering. I need a steady supply of Nitrogen (N) for healthy leaf and stem development, Phosphorus (P) for strong root systems and to promote flower initiation, and Potassium (K) for overall plant vigor and disease resistance. As a flowering plant, I also benefit from secondary nutrients and micronutrients like magnesium and iron, which support chlorophyll production and prevent leaf chlorosis (yellowing).
For optimal growth, a balanced, slow-release fertilizer is highly recommended. A formula with an NPK ratio close to 8-8-8 or 10-10-10 provides an equal proportion of the primary macronutrients I need. Alternatively, a formulation slightly higher in phosphorus, such as a 10-20-10, can be applied just before and during my main flowering periods to enhance bud formation and bloom production. To address my micronutrient needs, especially if grown in containers where soil depletion occurs faster, a fertilizer that includes minor elements or an occasional supplement with chelated iron or Epsom salts (magnesium sulfate) is beneficial.
My growth and feeding schedule align with the warm seasons. I am actively growing from early spring through late summer, which is when I require the most nutrients.
Early Spring (March-April): As new growth emerges and temperatures rise, begin the fertilization season. Apply a balanced, slow-release granular fertilizer around my drip line (the area under the outermost reaches of my branches), following the product's dosage instructions. This initial feeding provides the energy for my spring growth flush.
Late Spring to Summer (May-August): This is my main period of growth and flowering. Apply a balanced liquid fertilizer or another dose of slow-release fertilizer every 4-6 weeks. Consistent feeding during this time supports continuous flowering and maintains the deep green color of my foliage.
Early Fall (September): Apply a final, lighter application of a balanced fertilizer. This helps me recover from the summer bloom and strengthens my tissues before the cooler, dormant months. Avoid fertilizing after mid-fall.
Late Fall and Winter: I enter a period of slowed or dormant growth. Fertilization should be completely halted during this time, as I cannot process the nutrients. This can lead to fertilizer salt buildup in the soil, which can damage my root system.
If I am grown in a container, my roots are confined and cannot seek nutrients beyond the pot. This makes regular feeding more critical. However, the risk of fertilizer salt buildup is also higher. Use a diluted liquid fertilizer at half-strength every 4-6 weeks during the growing season, and ensure the pot has excellent drainage. Flushing the soil with water every few months helps to wash away any accumulated salts.
