Aphids
Aphids are small, soft-bodied insects that cluster on new growth and leaf undersides, sucking sap and excreting sticky honeydew.
가능한 원인
New Growth Attraction
Why: Aphids are drawn to tender, nitrogen-rich new growth, which is easier to pierce and feed on.
Signs to check: Clusters of small insects on stem tips, flower buds, and youngest leaves.
Over-Fertilization with Nitrogen
Why: Excess nitrogen produces soft, sappy growth that is highly attractive to aphids.
Signs to check: Lush, rapid foliage growth, aphids concentrated on the newest growth.
Introduction from Outdoors or New Plants
Why: Aphids can fly in through open windows or arrive on plants brought in from outside.
Signs to check: Aphids appeared suddenly, plant was recently moved indoors or near an open window.
