China aster

Susceptible plants Cherry, rose, viola, China aster, apple, peach, pear, plum, and strawberry. 

Damage is usually caused by a blockage of the water-conducting tissues of the stem, starving the leaves of water. Wilts can persist in the soil for several years, entering plants through wounds. Commonly associated with eelworm attack. Some wilts, e.g., of China asters and peas, are host-specific, while others attack a wide range of plants.

China asters tolerate light shade only. They thrive in fertile, moist but well-drained soil in full sun. China asters are shallow-rooted, so cover soil with a 1" mulch to retain soil moisture and keep roots cool. Pinch growing tips to promote bushiness. Water regularly so soil stays slightly moist.

Lower leaves yellow, wilt, and die. Cause Fusarium wilt. Other symptoms of this common fungal disease include yellowing and wilting of 1 side of plant only drooping flower heads stunted mature plants dark brown areas on stems and partial or total root decay. Once introduced on diseased plants or transmitted by wind, water, or handling, Fusarium wilt lives on indefinitely in soil. There is no cure. Remove infected plants and dispose of them in sealed containers in household trash. Never plant China asters in the same location 2 years in a row. Wilt-resistant cultivars are available, but they are not completely immune. 

Plants Affected A wide range of woody and herbaceous plants. Aster yellows affects many plants, including carrots, lettuce, tomatoes, China asters, and gladiolus. Elm yellows (also known as elm phloem necrosis) attacks several species of elms.
