Bacterial soft rot: Ensure well-drained soil and dispose of severely affected plants to prevent spread.
Grey mould (Botrytis): Improve air circulation around plants and remove any infected debris promptly.
Slugs and snails: Use physical barriers like copper tape or apply iron phosphate pellets to control populations.
Thrips: Monitor regularly and use sticky traps or introduce natural predators like lacewings.
Aphid-borne viruses: Remove and destroy infected plants immediately to prevent transmission to healthy irises.
