To manage rust, remove and destroy all infected leaves and ensure that the plant has adequate air circulation. Consider applying a copper-based fungicide as a preventative measure.
Root Rot: Root rot is a common problem in plants that are overwatered or have poor drainage. It can cause the roots to decay, leading to stunted growth and wilting of the leaves. To manage root rot, remove the plant from the soil and inspect the roots. Cut away any soft or discolored roots and replant the plant in fresh, well-draining soil.
Common Pests
Aphids: Aphids are common pests that can suck the sap from the leaves of Knowltonia anemonoides H.Rasm. subsp. tenuis H.Rasm. This can lead to curled and distorted leaves. To manage aphids, wash the plant with a strong jet of water or apply an insecticidal soap or oil spray.
