Plant Care

Sweet Flag is remarkably easy to maintain and requires minimal attention once established. Regular watering is essential to keep the soil consistently moist, especially during dry spells. Remove any dead or yellowing foliage to maintain appearance. The plant can be divided every 3-4 years in spring to maintain vigor and prevent overcrowding. No deadheading is necessary, and the plant is generally pest and disease resistant.

Planting Instructions

Plant Sweet Flag in spring or early summer in moist to wet soil. Dig a hole twice the width of the root ball and at the same depth. Place the plant in the hole, ensuring the crown is level with the soil surface. Backfill with soil, firm gently, and water thoroughly. Space plants 12-18 inches apart to allow for mature spread. Apply a layer of mulch around the base to retain moisture and suppress weeds.
