Several pathogens cause fungal Crown or Root rot diseases in Hakonechloa. Crown injury and excess moisture during dormancy also increase the chances of infection. Choose well-drained sites. Add organic matter to improve soil drainage. Keep winter mulch away from crowns. Remove and discard infected plants and the surrounding soil.

Spider mites are known to cause problems for Hakonechloa plants. Hose off plants when symptoms first appear. A strong stream knocks mites off plants and may give control. Introduce predatory mites. For severe infestations, spray plants with insecticidal soap or pyrethrin.
