The lower leaves of my evening primrose plants all have brown spots and the condition seems to be climbing. At the very top, the burgeoning flower pods look beautiful and emerald green, but I fear they will be overtaken by whatever the problem is. The seeds were saved from previous years. The seeds manifested in Virginia, and the plants in question are growing in Michigan. It has rained a lot and the plants are in pots with built-in drainage saucers, so they might have too much water (?). Any suggestions? Does it sound like a nutrient deficiency or a fungus…?
Check the soil, it is moist or soggy? It may be that the roots have suffered some root rot.
Make sure that the excess water is freely draining from the pot.
