Salad Greens in London Pots: Aphids or Whiteflies

Symptoms

Small holes with brown edges, not slug damage, no caterpillars = piercing-sucking insects (aphids, whiteflies).

Organic Control

• Insecticidal soap or pyrethrum spray.
• Both safe up to harvest day.
• Buy at garden centres or Gardens Alive.

Check Undersides

Spray thoroughly—pests hide under leaves. Repeat weekly until clean.
