I have a beautiful Petunia Tiny Tunia Violet plant which has been flowering nicely (in sun and shade environment). Suddenly, a few days ago, it began to look like it's dying--stalks all dried out. Is this normal? I have kept it moist. Should I cut it back and will it bloom next year? It is a perennial, isn't it?
Hybrid garden petunias should be watered regularly, placed in well-draining, compost enriched soil. The plant may be responding to too much water; stem die-back like you have described is the result of a vascular problem, resulting from roots drying out from too little water, or root rot from too much water. The roots may also be affected by a soil fungal pathogen. If the roots die, then there is no nutrient and water delivery to the stems/vegetative tissue, causing the vegetative tissue to die. If the soil is remaining moist, allow the soil to dry out a bit and water sparingly. You may have to propagate vegetatively if the plant is in continual decline. You can reference this website for more information about petunia horticulture.
