Watch out for

Slugs and snails: Use beer traps, copper tape barriers, or iron phosphate-based pellets to control populations.

Vine weevil: Apply nematodes (Steinernema carpocapsae) to the soil in late summer or autumn.

Powdery mildew: Improve air circulation and spray with a potassium bicarbonate solution if severe.

Aphids: Encourage natural predators like ladybirds or blast off with a strong jet of water.
