Phalaenopsis 'Green Lightning' is a highly eye - catching Phalaenopsis variety in the yellow - green color series. Its petals are medium - to - large in size. What makes it unique is that the edges of the petals are inlaid with striking rose - pink lightning - shaped patterns, and the labellum part shows a gorgeous rose - red color. However, the flower shape of 'Green Lightning' has certain instability. During the cultivation and growth process, it is prone to the phenomenon of atavism.

The flowering period of Phalaenopsis 'Green Lightning' is 2 - 3 months. When it blooms, the flower stem first emerges and then the flower buds grow, and the flowers open one by one. The flowers are the most colorful in the middle stage, and gradually wither in the later stage.

The reasons for the yellowing of the leaves of Phalaenopsis 'Green Lightning' and the corresponding solutions are as follows:

**Watering**: Excessive watering can lead to root rot and lack of oxygen, while insufficient watering can cause water shortage and dryness. Water should be applied according to the principle of "watering when the soil is dry and thoroughly wetting it". Insert your finger 2 - 3 cm into the soil to judge its dryness or wetness. Avoid splashing water directly on the plant. When the soil is dry, increase air humidity while ensuring good ventilation.

**Lighting**: Excessive strong light can cause burns and yellow spots on the leaves, while too little light can make the leaves yellow and thin. It needs bright diffused light. Shade in summer and supplement light in winter, with 4 - 6 hours of light exposure per day.

**Temperature**: The suitable temperature range is 18 - 28°C. If the temperature is too high, growth will be inhibited and the leaves will turn yellow and wither. If the temperature is too low, frost damage will occur, and the leaves will develop yellow spots. Cool down in summer and keep warm in winter. Keep the room temperature above 15°C and prevent drastic temperature changes.

**Fertilization**: Excessive fertilization can cause fertilizer damage, root injury, and leaf scorching and withering, while insufficient fertilization can lead to yellowing of the leaves due to nutrient deficiency. Apply thin fertilizers frequently. During the growth period, apply a thin liquid fertilizer every 2 - 3 weeks. Increase phosphorus and potassium fertilizers during the flowering period. Apply the fertilizer away from the roots and water after fertilization. Adjust the fertilization plan according to the plant's needs.

**Daily Maintenance Key Points of Phalaenopsis 'Green Lightning'**:

**Soil and Flower Pot**: Select a substrate that is loose, breathable, and well - drained, such as a mixture of bark, etc. Use a terracotta pot or a multi - hole plastic pot. The diameter of the pot should be 2 - 3 cm larger than the diameter of the roots.

**Ventilation**: Keep the air circulating. You can open windows or use a fan, but ensure the wind force is appropriate.

**Pruning**: Timely cut off withered flowers, yellow leaves, and old roots. After flowering, leave 3 - 4 nodes of the flower stem. Trim the overall plant shape by removing long, dense, and crossed branches.

**Pest and Disease Control**: Prevent diseases such as anthracnose, soft rot, and pests such as scale insects. Check the plant's condition regularly. If there are diseases, use fungicides such as carbendazim. If there are pests, combine physical and chemical methods. Use insect - proof nets and insecticides such as omethoate. Select low - toxicity and high - efficiency pesticides and use them according to the instructions.
