Psidium guajava, commonly known as guava, is a tropical tree in the Myrtaceae family. Native to Central America, it is widely cultivated in tropical and subtropical regions around the world. The tree produces edible fruits that are rich in vitamin C and dietary fiber. Guava trees prefer seasonally dry tropical climates and can tolerate a range of soil types.
Guava trees require bright, direct sunlight for optimal growth. They thrive in warm temperatures and moderate humidity. Water the tree regularly, allowing the soil to dry out partially between waterings. Guava trees are relatively easy to care for but do require some attention to pruning and fertilization.
収穫
Guava (Psidium guajava) is typically ready for harvest 90 to 150 days after flowering. The fruit should be picked when it changes color from green to yellow, indicating ripeness. Harvesting is usually done by hand, ensuring to handle the fruit gently to avoid bruising. It is best to harvest in the morning when temperatures are cooler. Post-harvest, the fruit should be stored in a cool, dry place to extend its shelf life.
土壌
Guava trees prefer well-draining loamy soil that is rich in organic matter. The soil should be kept moderately moist but not waterlogged. Good drainage is essential to prevent root rot.
肥料
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize the tree every 2-3 months during the growing season to promote healthy growth and fruit production.
植え替え
Young guava trees can be repotted every 1-2 years to provide fresh soil and more space for root growth. Choose a pot that is slightly larger than the current one and ensure it has good drainage. Repot in the spring before the growing season begins.
伝搬
Guava trees can be propagated from seeds, cuttings, or air layering. Seeds should be sown in a well-draining soil mix and kept warm and moist until germination. Cuttings should be taken from healthy, mature wood and rooted in a moist, well-draining medium.
剪定
Prune guava trees regularly to maintain their shape and remove any dead or diseased branches. Pruning should be done in late winter or early spring before new growth begins. This helps to improve air circulation and light penetration within the canopy.
毒性
Guava trees are not toxic to pets or humans. The fruits are edible and safe to consume. However, the seeds can be hard and should be chewed carefully to avoid dental damage.
追加
Guava trees can be susceptible to pests such as fruit flies, aphids, and scale insects. Regular monitoring and appropriate pest control measures can help keep these issues in check. Additionally, mulching around the base of the tree can help retain soil moisture and suppress weeds.
