What causes blackened leaf tips and root rot in Chinese orchids (Cymbidium)?
1. Excessive temperature and direct sunlight easily scorch the leaf tips. 2. The potting medium is too rich and stays wet without drying out; in mild cases this causes poor root development and blocked nutrient uptake, making the leaf tips prone to blackening, and in severe cases it causes root rot and death of the orchid plant. 3. Pests. There is a pest similar to aphids that congregates in the potting soil and lives on the orchid roots; it is very small and usually hard to spot, and although its direct damage is not great, it easily infects the orchid roots with disease, causing root rot.
