Understanding The Common Causes Of Brown Leaves In Geraniums

Brown leaves on geraniums can be caused by various factors: overwatering, underwatering, nutrient deficiency, pest infestation, and environmental stress. Overwatering is the most common cause, so make sure you let the soil dry between waterings. Underwatering can cause the plant to become stressed and drop its leaves, but more often than not, leaves turn brown due to overwatering.

Nutrient deficiency can also cause brown leaves, so it’s important to use a fertilizer that’s designed for geraniums. Pest infestation is often overlooked but can be a major problem. Finally, environmental stress, such as a sudden change in temperature or humidity, can cause brown leaves.

Keeping an eye on these factors will help you keep your geraniums looking healthy and beautiful all year round.
