What are the symptoms of crown gall in geraniums?
Symptoms of crown gall in geraniums: it occurs mainly at the root crown, with sporadic cases also on lateral roots. At the affected sites, galls of various sizes and shapes form. They are usually spherical or flattened spheres, and may also join together into irregularly shaped small primary galls, grayish white or flesh-colored, soft in texture, with a smooth surface, later gradually turning brown to dark brown and becoming lignified gall-like growths. The surface of the lignified galls is rough or uneven, and cracked. Affected plants have poorly developed root systems, few fine roots, and slow growth; in severe cases the leaves turn yellow and drop early.
