Aphids often gather on tender new growth, flower stalks, and leaf backs. They feed on plant sap and may leave honeydew, which can attract ants and encourage fungal issues.
Early detection is important. Check new growth regularly, isolate affected plants, and remove pests before the colony becomes large.
Control options include physical removal, suitable insecticidal products, and improving growing hygiene. Always match the treatment to the plant, pest level, and product instructions.
