The Gardening Year

Watch out for

Iris leaf spot: Remove and dispose of affected foliage at the end of the season and avoid wetting leaves when watering.

Iris rust: Pick off lightly infected leaves early in the season and ensure good air circulation around plants.

Bacterial soft rot: Ensure well-drained soil and avoid overwatering; remove and destroy severely infected plants immediately.

Slugs and snails: Use physical barriers like copper tape or apply iron phosphate-based pellets around the base of plants.

Vine weevil: Apply systemic insecticides or biological controls like nematodes to the soil during warm months.
