In this article, we will discuss the reasons why geranium leaves turn yellow and brown and provide you with effective solutions to help your plants thrive.

Detailed Discussion on Geranium Leaves Turning Yellow and Brown: Reasons and Solutions

Geranium leaves can turn yellow and brown due to several factors, including:

1. Overwatering or Underwatering

– Overwatering can lead to root rot, causing the leaves to turn yellow or brown.
– Underwatering can result in dry soil, causing the leaves to become yellow and crispy.

Solution: Strike a balance by allowing the top inch of soil to dry out before watering again. Ensure proper drainage to prevent waterlogged soil.

2. Nutrient Deficiency

– Lack of essential nutrients like nitrogen, iron, or magnesium can cause yellowing and browning of geranium leaves.

Solution: Feed your geraniums with a balanced fertilizer containing these vital nutrients. Follow the recommended dosage and frequency.

3. Incorrect Sunlight Exposure

– Insufficient sunlight can weaken the plant and cause yellowing of leaves.
– Excessive exposure to direct sunlight can scorch the leaves, resulting in browning.

Solution: Place your geraniums in a location where they receive 4-6 hours of sunlight per day. Provide some shade during intense afternoon sun.

4. Pests and Diseases

– Aphids, whiteflies, and spider mites may attack geraniums, causing leaf discoloration.
– Fungal and bacterial diseases like powdery mildew and leaf spot can also lead to yellow and brown patches.

Solution: Regularly inspect your plants for pests and diseases. Use organic or chemical insecticides or fungicides as directed and maintain good plant hygiene.

5. Aging and Natural Leaf Shedding

– As geraniums mature and produce new leaves, older leaves may turn yellow and drop off, which is a natural process.

Solution: Prune away dead or yellowing leaves to promote new growth and maintain plant aesthetics.
