What aphids look like

Aphids are small pear-shaped insects that cluster in groups. They love:

  • New shoots
  • Flower buds
  • Soft stems

They can be green, black, brown, or even pink.

Signs you have aphids

  • Leaves curling around the tips
  • Sticky honeydew on leaves
  • Sooty mold developing on sticky spots
  • Ants hanging around your plants

Treatment plan

Quick win: spray them off

Aphids are weak. A strong rinse often removes most of them.

  • Focus on new growth and underside of leaves.

If they return

  • Insecticidal soap is effective
  • Repeat every few days for 1 to 2 weeks

Prevention

  • Do not over-fertilize with high nitrogen
  • Inspect new growth weekly
  • Keep plants spaced for airflow
