This is Taylor Campbell, horticulture extension agent at North Carolina Cooperative Extension Burke Center. Today’s program is on how to identify root rot. Healthy roots are always white. Brown roots can be a symptom of phytophthora root rot, a fungal disease. Phytophthora root rot develops when roots are compacted in an exceedingly wet, warm environment. The fungal pathogen develops in these conditions and begins feeding on the roots, which causes the roots to rot. Root rot causes yellowing leaves and leaf drop, as well as bare patches in the foliage. By the time you notice these symptoms, the damage has already been done. Root rot is irreversible once the roots start to decay. Roots can sometimes be salvaged, but this is uncommon. Prevention is key. Start with buying healthy plants. Don’t be afraid to remove plants from pots at the store to look for healthy white roots. Once you get it home to plant it, be sure you plant in a location without constant standing water. If you are planting in a container or pot, be sure the pot has a drainage hole as root rot is very common among potted plants. Aerating the soil can also be beneficial to allow oxygen into the soil, as oxygen promotes healthy root growth. Avoid irrigating more than necessary, as all plants are susceptible to root rot.
