Lagerstroemia indica, commonly known as crape myrtle, is a deciduous shrub or small tree native to China and Korea. It is well-known for its long-lasting summer flowers and attractive, peeling bark. The plant thrives in subtropical climates and can reach heights of up to 6 meters. It undergoes a dormancy period during the winter months.
Crape myrtle requires bright, direct sunlight for optimal growth and should be kept in moderate temperatures. It prefers moderate humidity levels and should be watered when the soil partially dries out. Regular pruning is necessary to maintain its shape and encourage flowering.
土壌
Lagerstroemia indica prefers well-draining loamy soil. It can tolerate a range of soil types but performs best in slightly acidic to neutral pH levels. Ensure the soil has good drainage to prevent waterlogging.
肥料
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize in early spring before new growth begins and again in mid-summer to promote healthy growth and flowering.
植え替え
Repot young plants every 2-3 years to refresh the soil and provide more space for root growth. Mature plants can be repotted less frequently. Choose a pot that is slightly larger than the current one and ensure it has good drainage.
伝搬
Crape myrtle can be propagated through softwood cuttings taken in late spring or early summer. Dip the cuttings in rooting hormone and plant them in a well-draining soil mix. Keep the soil moist and place the cuttings in a bright, indirect light until roots develop.
剪定
Prune crape myrtle in late winter or early spring before new growth begins. Remove any dead or diseased branches and thin out crowded areas to improve air circulation. Pruning helps maintain the plant's shape and encourages more prolific flowering.
毒性
Lagerstroemia indica is not toxic to pets or humans. All parts of the plant are considered safe, making it a good choice for gardens where pets and children are present.
追加
Crape myrtle is known for its resistance to powdery mildew, a common issue in many other plants. However, it can still be susceptible to aphids and other pests, so regular monitoring and appropriate pest control measures are recommended.
