Plant disease
Pepper, bell None Given
I have a bell pepper in a patio container - full sunlight. Plant seems to be flourishing but black spots have appeared at the 'Y' joints where leaves join the stalk. Lower leaves seem to be wilting somewhat. Too much water, or ????? Thanks

I think it may be early blight disease caused by fungus Alternaria solani. The main symptoms are appearance of black spots on leaves and lower stem. The leaves turn yellow to brown and fall off.
The disease is favored by high humidity and warm temperature. The disease mainly spreads through splashing water so avoid overhead watering. Copper based fungicides are effective against early blight.

The container must be well-draining, with holes at the bottom so there is no standing water at the bottom of the container. If the container is in a saucer, the saucer must be upside down so it does not hold any water. In high humidity climates, it is easily possible to over-water. These practices will avoid many problems.
