Pests
Aphids: Aphids are small, soft-bodied insects that suck the sap from the leaves, stems, and flowers of the plant. They can cause a reduction in the plant's health and vigor. To manage this pest, it is important to remove them physically or use insecticidal soap.
Spider mites: Spider mites are tiny, white, or yellowish insects that can spin webs on the plant. They suck the sap from the plant, causing the leaves to turn yellow and fall off. To manage this pest, it is important to keep the plant well-watered, remove infested plant parts and use insecticidal soap.
By following the above-mentioned tips for disease and pest management, you can help ensure that your Oxalis stellata Eckl. & Zeyh. var. stellata remains healthy and vibrant.
