The propagation of crape myrtle
Lagerstroemia indica, commonly known as crape myrtle, is native to China and belongs to the genus Lagerstroemia in the family Lythraceae. It has a long history of cultivation, with records dating back over 1500 years. In China, it is a significant tree during the summer season, admired for its long blooming period and vibrant colors. As urban greening becomes increasingly important, crape myrtle has gained more attention due to its ornamental value and adaptability.
Crape myrtle is a deciduous shrub or small tree that comes in various colors, including white (L. var. alba), lavender (L. var. amabilis), and pink (L. var. rubra). Recently, the cultivar 'Petite Pinkle' from the United States and Japan has become popular. It features flowers in shades of pink, purple, white, and even pink with red and white borders. With its compact growth habit and colorful display, this variety is ideal for landscaping and has great potential for future development.
Cultivation and care of crape myrtle are relatively straightforward. It thrives in well-drained, fertile sandy soil and prefers full sun, which is essential for abundant flowering. While it is cold-hardy, young plants need protection during winter, while mature trees three years or older can tolerate colder temperatures without special care. The plant is drought-tolerant but sensitive to waterlogging, so watering should be done only when necessary. During the rainy season, proper drainage is crucial to prevent root rot. Fertilization should occur after leaf fall in winter and before new growth in spring, using organic materials like compost or diluted manure for best results.
Pruning is an important part of crape myrtle maintenance. After the leaves fall in autumn, remove any weak, crossing, or diseased branches to encourage healthy growth and a well-structured canopy. This helps the tree develop a strong framework and improves its overall appearance.
Pests such as aphids, scale insects, and leaf roller moths can affect crape myrtle. Insecticides like dimethoate EC (1000 times dilution) and dichlorvos (1500 times dilution) can be used to control these pests effectively.
Propagation is typically done through seeds or cuttings, with cuttings being the preferred method due to higher survival rates and faster growth. For seed propagation, collect ripe seeds in October, dry them, and store them in a cool, dry place. Before planting in March, soak the seeds in a 0.2% potassium permanganate solution for 24–48 hours, then rinse and soak them in warm water (40–50°C) for 2–3 days. Sow them in a prepared seedbed, keep the soil moist, and expect seedlings to emerge within about 50 days. Transplant them once they reach 10–15 cm in height.
For cuttings, take semi-hardwood cuttings in late April or June. Select healthy, disease-free branches and cut them into 16–15 cm lengths. Plant them in loose, well-draining soil, cover with a thin layer of soil, and keep them moist. After about 40 days, roots should form, and the cuttings can be gradually exposed to sunlight. By the following year, they can bloom.
The "cutting method" is a technique used to enhance flowering in crape myrtle. By pruning the main trunk at a certain height, the plant focuses energy on producing more lateral shoots, leading to more blooms. Proper watering, fertilization, and regular pruning help maintain the desired shape and promote better flowering.
Dwarf crape myrtle varieties are particularly suited for urban landscapes. They are hardy, resistant to drought, salt, and pollution, and can thrive in a wide range of climates. These plants are easy to manage, suitable for both large and small spaces, and can be transplanted successfully with high survival rates. Their compact size makes them ideal for gardens, streetscapes, and public areas, offering beauty without requiring excessive space.
