This not only affects the ornamental value of orchids, but may also adversely affect the growth of orchids. This article will analyze the reasons for uneven orchid leaves and provide corresponding maintenance suggestions. Reasons for uneven orchid leaves 1. Soil problems Soil is the basis for orchid growth. If the soil has poor permeability and poor drainage, it will lead to poor breathing at the roots, which will affect the growth of orchids. Harmful substances in the soil will also cause orchid leaves to appear uneven.

Too much watering will cause water in the roots and affect root breathing; Too little watering will cause the leaves to lose water and the leaves to become thinner.
