Soil-inhabiting fungi infect and kill root and lower stems of plants. While healthy plant roots are normally white and firm, those with root rot turn black and become soft and mushy. These struggling bushes are in the low point of the yard where water cannot drain easily. Root rot shriveled up the flowers on the right side of the flower bed. Plants wilt, dieback and lose vigor.
Control is difficult because symptoms normally appear after damage to the stem or root is severe.
Ensure proper drainage and allow excessively wet soils to dry. Plant in raised beds if drainage is marginal. Avoid crowding plants in beds. Privacy Statement 2001 City of Austin, Texas . All Rights Reserved.
