Powdery mildew: Improve air circulation, avoid overhead watering, and treat with a fungicide if severe.
Vine weevil: Use nematodes or insecticidal drenches to control soil-dwelling larvae.
Slugs and snails: Apply slug pellets, use beer traps, or hand-pick at night to reduce populations.
Root rot: Ensure pots have drainage holes and allow compost to dry slightly between waterings.
Scale insects: Wipe off with a damp cloth or treat with horticultural oil during the growing season.
