Care
Catmint ‘Summer Magic’ Care
Plant in full sun for best flowering. It tolerates light shade, though fewer blooms may appear. Prefers well-drained soil and will perform well even in drier, lean conditions once established.
Water regularly during establishment, then occasionally during prolonged dry periods. Avoid overwatering, as this can cause root stress or crown rot.
Feed lightly in spring with a balanced slow release fertilizer to encourage growth and flowering without overstimulation.
After the first bloom cycle, shear spent flower spikes to encourage reblooming and maintain a compact form. In early spring, cut old growth back to the ground to promote fresh new foliage.
