Causes and treatments for yellow leaves of octopus orchid

1. Soil issues

Reason: Octopus orchid originally grows in cold mountainous areas and has low requirements for soil. However, generally, you should choose soil with good drainage and air permeability. Soil with poor drainage and poor air permeability can easily lead to water accumulation in the pot. If the pot is damp for a long time, some roots are prone to rot and cannot provide sufficient nutrients to the leaves. If the leaves lack sufficient nutrients, yellow leaves will appear.

Solution: At this time, the flower soil needs to be replaced in time. It can usually be replaced with fine-grained volcanic rock, bark or burnt earth.

2. Temperature is too low

Reason: It is not cold-resistant and is suitable for growing in a high temperature, high humidity and well-ventilated environment. If the temperature is too low, the leaves will gradually turn yellow, the roots will turn dark brown, and eventually some plants will die. Even plants that have not died will recover very slowly after the temperature rises.

Solution: Place the plant in a warm and well-lit place indoors and reduce watering to ensure the roots are relatively dry. If the indoor temperature is lower than 8℃, take measures to keep warm. During daily maintenance, the plant growth temperature must be maintained between 15-35℃. It is hot in summer, so avoid excessive temperatures and cool down appropriately. The temperature in winter cannot be lower than 8℃.

3. Too little fertilizer

Reason: Octopus orchid plants are large and require more fertilizer, especially during the vigorous growth period. Insufficient nutrients can cause malnutrition of the plant and result in yellow leaves.

Solution: If yellow leaves are caused by insufficient fertilization, just apply fertilizer in time. During normal maintenance, try to keep fertilizing once every 1-2 weeks. During the growing period, increase the frequency and amount of fertilization appropriately. Liquid compound fertilizer can be used as fertilizer, and try not to use granular fertilizer as it is difficult for the plants to absorb. Fertilization can be suspended during the flowering period and the cold winter period.
