Questions tagged [diseases]

For questions related to plant diseases.

Plants can be infected by a number of diseases. These can be caused by micro-organisms (e.g. bacteria, fungi, viruses; and multi-cellular creatures such as nematodes).

Macroscopic creatures (e.g. mites and aphids) and water/nutrient problems (too little or too much) can also cause symptoms that can be confused with diseases.

Use this tag for all questions related to diseases - especially diagnosis, management, and cures. Please include pictures of the affected parts of the plants.
