How to tell if a plant has rot?
Root rot can be identified by the presence of soft, brown roots. 2 The root system of a healthy plant should be firm and white. But when soil is soggy, fungal spores multiply and the fungus starts to spread 3, developing in the extremities of the roots first. As the fungus advances, healthy portions of root turn brown and mushy as the roots die. The plant is then unable to absorb the nutrients it needs, and that deficiency becomes apparent in the condition of plant foliage. Leaves begin to wilt and turn yellow or fall off, growth slows, and blooming may be delayed. 1 In the most extreme cases, when conditions are ideal for the fungus to spread quickly, plants can die within 10 days. 3 If these symptoms occur in a plant, loosen the soil around the base of the plant with a hand trowel or shovel and remove the plant from the soil. Gently shake the soil from the roots and inspect them for rot.
