Why Do Geranium Leaves Turn Yellow ? 11 Reasons

Yellow leaves in geraniums are quite common, so it is essential to know what is the correct reason behind this paleness, in order to bring them back to their lush green glory!

If the leaves on your geranium plants start turning yellow, the main reason could be overwatering. These plants prefer dry conditions, and only need water once the top layer of soil begins to dry out.

Too much watering can make the leaves turn mushy and pale in no time.

On the flip side, if geraniums are underwatered, they start turning yellow as well. This happens because they can tolerate drought, but prolonged dryness can stress the plant.

If you think it has been a while since you last watered your plant and the soil is very dry, water it right away.

Another reason why geraniums turn yellow is a lack of sunlight. They require at least 5-6 hours of direct or partial sunlight per day, and if you have placed them where this condition is not met, their leaves will start turning yellow.

Due to a lack of proper knowledge about fertilization, geraniums may be either over-fertilized, which burns the roots, or under-fertilized, causing the plant to struggle to get nutrients.

To find the right balance, feed the plant using a balanced liquid fertilizer, every 7-8 weeks, after diluting it to 1/4 of its strength. Also, refrain from feeding in colder months.

Geraniums thrive in warm climates, and when the weather becomes extremely cold, they enter the dormancy phase, where the leaves start turning yellow. Once the temperature rises again, the yellow leaves will fall off and new growth will begin.

Also, avoid exposing the plant to cold drafts and AC vents. The plants may die if they are exposed to temperatures below 35°F (2°C) for long.
