Why Are Geranium Leaves Getting Smaller and Smaller? Causes Explained

Geranium is a sun-loving plant, and if it does not get enough light, its leaves will get smaller and smaller. It grows best in loose, breathable, well-draining and fertile sandy soil; if the soil is unsuitable, its leaves will also get smaller and smaller, and insufficient nutrients and overwatering can also cause geranium leaves to get smaller and smaller.

Reasons Why Geranium Leaves Get Smaller and Smaller

1. Insufficient Light

Geranium is a sun-loving plant, and the growth of its leaves requires sufficient light. If the light is insufficient, it cannot carry out photosynthesis, and so its leaves will get smaller and smaller. Therefore, at this time we need to supplement light for it, but be careful not to let it be exposed to strong sunlight in summer.

2. Unsuitable Soil

Geranium has certain requirements for soil. It grows best in loose, breathable, well-draining and fertile sandy soil. If the soil is unsuitable or the soil is not replaced with new soil for a long time, its root system cannot absorb nutrients and water, and so the plant's leaves are prone to getting smaller and smaller.

3. Insufficient Nutrients

Geranium leaves getting smaller and smaller may also be caused by insufficient nutrients. During its growing period, it needs to be fertilized, especially when growing leaves, when an appropriate amount of nitrogen fertilizer can be applied, as this is beneficial to the growth of its leaves. However, note that it is not tolerant of heavy fertilizer, so fertilization should follow the principle of applying thin fertilizer frequently.

4. Overwatering

Geranium likes to grow in a slightly dry environment. It is a plant that is not tolerant of waterlogging. If it is overwatered, its roots are prone to rotting, which will lead to poor growth, and the leaves will also get smaller and smaller. Therefore, when caring for geraniums, it needs to be watered reasonably.
