Reproduction Management Techniques and Methods of Jade Leaf Golden Flower
Propagation of Jacaranda is typically done through cuttings, which is the most common and efficient method. In early spring, choose healthy one-year-old branches that are vigorous and strong. Cut the stems into 8 to 12 cm lengths, making a 45-degree angle at the bottom. Before planting, soak the cut ends in a diluted potassium permanganate solution for 1 to 2 hours to prevent disease. Use a well-draining medium such as river sand or perlite, and insert the cuttings halfway into the soil. Water them thoroughly after planting.
For optimal growth, maintain high humidity (around 80–90%) and provide shade during the initial stages. Mist the foliage and surrounding area regularly to keep moisture levels consistent. Within 10 to 15 days, the cuttings should develop roots and become established.
Alternatively, seed propagation is also possible, though it’s more time-consuming and less reliable. Collect fresh seeds in early summer and let them dry in a cool, ventilated area. To improve germination rates, soak the seeds in a 1–2% potassium permanganate solution at around 30°C for 1 to 2 hours. After drying, sow them in well-drained soil, covering them with about 1 cm of soil. Keep the soil moist and provide shade. Germination usually occurs within 7 to 10 days.
When growing Jacaranda, ensure it receives full sun or partial shade, whether planted in the ground or in pots. Once the seedlings have developed 3 to 5 pairs of leaves, they can be transplanted into pots or bags. Use a loose, nutrient-rich loam or sandy loam soil, and water immediately after transplanting to help establish roots. Prune the foliage slightly after transplanting to reduce water loss due to root damage.
Jacaranda thrives in temperatures between 20°C and 30°C. Keep the soil consistently moist and fertilize monthly with a balanced fertilizer. As the plant grows, perform regular pruning to encourage bushiness and compact growth. Remove any leggy, diseased, or crowded branches to improve air circulation and light penetration. After flowering, remove the spent blooms to conserve energy and promote future blooming.
During the growing season, ensure adequate sunlight and manage watering carefully. In hot summers, mist the leaves to lower the temperature. Regularly remove weeds to improve soil aeration. During the flower bud stage, apply a diluted liquid fertilizer, and consider foliar feeding for better nutrient absorption. After each pruning, water thoroughly. A week later, apply a light dose of fertilizer with added phosphorus and potassium to support new growth and flowering.
At the seedling stage, focus on phosphorus and potassium to strengthen the roots. During the flowering period, use a diluted fertilizer and consider foliar applications. Mature plants may benefit from two additional phosphate applications during bloom. After flowering, prune to control excessive growth and maintain shape.
In colder regions, protect Jacaranda from frost. If temperatures drop below 0°C for extended periods, the above-ground parts may die back. Therefore, in southern open fields or northern containers, provide insulation during winter to ensure the plant survives the cold season safely.
