Care
Catmint ‘Summer Magic’ Care
Plant in full sun for best flowering, though light shade is tolerated. Provide well-drained soil; plants perform well in average to lean conditions once established.
Water regularly during the first growing season to establish roots, then reduce frequency. Allow soil to dry slightly between waterings to prevent excess moisture around the crown.
Apply a balanced slow release fertilizer in spring to support steady growth and flowering.
After the first bloom cycle, shear spent flowers to encourage additional flowering and maintain a compact shape. Cut back old growth in early spring before new foliage emerges.
Container Growing
Catmint adapts well to containers with excellent drainage. Container-grown plants may require more frequent watering than those in the ground. Position in full sun for strongest flowering.
Plants hardy in the ground may require winter protection when grown in containers in colder zones.
