Cultivation Methods and Precautions for Potted Orchids

  1. Soil: For potted phalaenopsis orchids, use well-draining sandy soil that retains moisture. A suitable cultivation soil can be prepared by mixing sand, humus, peat moss, and compost in a ratio of 4:3:2:1.

  2. Watering: Phalaenopsis orchids require sufficient water. Water regularly to keep the soil moist. Avoid overwatering to prevent root rot. In spring, water once every 7 days when the soil feels dry; in hot summers exceeding 28 degrees Celsius, refrain from watering to allow dormancy; in the vigorous growth period of autumn, water every 2-3 days; reduce watering in winter to prevent frost damage.

  3. Fertilization: Fertilize primarily in autumn (September-October) before flowering and in spring (April-June) after flowering. Apply 20% decomposed human urine and cake fertilizer solution every 7-10 days. Autumn fertilization promotes flower bud differentiation, focusing on phosphorus fertilizer; spring fertilization stimulates vigorous foliage growth, focusing on nitrogen fertilizer; avoid fertilization in summer, especially during the hottest period, to prevent rot. Stop watering before fertilizing for better soil absorption.

  4. Light: Phalaenopsis orchids thrive in well-lit warm environments and prefer sunlight. The optimal temperature for phalaenopsis growth is 15-25 degrees Celsius. During spring, autumn, and winter, ensure approximately 7 hours of sunlight daily. In summer, when temperatures exceed 28 degrees Celsius, the plant enters dormancy and should be shielded from direct sunlight to avoid leaf burn. If exposed, move it to a cool, shaded area with proper ventilation. In winter, if temperatures drop below 15 degrees Celsius, flowers may not bloom, so indoor care is necessary.

  5. Precautions: Phalaenopsis orchids bloom from the tips of the current year's leaves. After the flowers wither, trim the top leaves by 3-4 nodes to promote flowering the following year. Repot young orchids annually to provide ample growing space. As light-loving plants, avoid frequent rotation of the orchid pot to maintain its sunward direction.

Above are the cultivation methods and precautions for potted phalaenopsis orchids. With proper care, phalaenopsis orchids can thrive beautifully.
