Aphids: Squash by hand or spray with a strong jet of water; use insecticidal soap if infestation is severe.
Powdery mildew: Improve air circulation, avoid overhead watering, and apply a fungicide if necessary.
Slugs and snails: Use physical barriers like copper tape or crushed eggshells, or apply slug pellets sparingly.
Root rot: Ensure well-draining soil and avoid overwatering; repot if necessary with fresh compost.
