Fungi thrive under wet conditions; Phytophthora rarely becomes an issue in soil that drains well. But, if anything is off so that they will not grow rapidly, you do get stem rot. Some stem plants refuse to grow for me no matter what I do. But, just as poor drainage enables excessive water to become a problem, so waterlogged soil is an enabler for Phytophthora. It is seen in both indoor as well as outdoor plants. Sometimes, the cause of root rot is not as simple as waterlogged soil. Proper diagnosis of the cause of the root rot. Symptoms Of Root Rot.

However, it is more common in indoor houseplants and symptoms are often shown when it is already too late and roots started to rot.
