|In November, I brought inside my potted geraniums. The outside of the leaves are turning yellow and soon the whole leaf is dried out. Also some leaves have black spots on them. The leaves look as if a fungus is destroying them. I am afraid that my other plants may get the same sickness. What is happening and should I separate them. Last year I brought my geraniums inside and had no problems with them.
|Unfortunately, based on your description I am not able to tell you exactly what is affecting your geraniums. These plants are potentially subject to a variety of foliage problems that can become apparent indoors. Some of what you are seeing may be part of the adjustment to being indoors. You might remove the worst affected leaves, then make sure the plants are in a spot with good air circulation. Avoid wetting the leaves when you water the plants, and make sure you are not overwatering the plants. Also, do not overfertilize them while they are indoors and growing less vigorously due to the reduced lighting conditions. If the problem continues, you might take a sample or two or some photos and consult with your local professionally trained nursery staff to obtain a more specific diagnosis. Good luck with your geraniums.
