Root rot is a common issue that affects plants, leading to wilting and decay. Recognizing root rot early is crucial for saving your plants. It typically manifests as brown, mushy roots with a foul odor, and above-ground symptoms include yellowing leaves and stunted growth.
What Are the Symptoms of Root Rot?
Root rot can be deceptive as it often starts below the soil surface. Here are some key symptoms to watch for:
