Watch out for

Mealybugs: Isolate the plant and treat with a systemic insecticide or dab spots with alcohol.

Root rot: Ensure sharp drainage and keep completely dry during winter dormancy.

Vine weevil: Use nematode treatments in soil or systemic insecticides for prevention.

Scale insects: Scrape off manually or apply a horticultural oil spray during active growth.

Sunburn: Acclimatise gradually to full sun and avoid intense midday exposure initially.
