ðą How to Care for Catmint to Prevent Aphids?
ð§ How to Water
Water deeply every 10-14 days once established. Catmint is drought-tolerant and prefers to dry out slightly between waterings. Avoid overwatering or soggy conditions which can lead to root rot.
âïļ Lighting
Catmint thrives in full sun (at least 6 hours of direct sunlight daily). It can tolerate light shade, especially in hotter climates, but flowering will be reduced. Full sun produces the most compact, floriferous plants.
ðŠī Ideal Soil
Use well-draining, average to poor fertility soil. Sandy or loamy soils are ideal. Avoid heavy clay or overly rich soils which encourage lush leafy growth at the expense of flowers. Soil pH between 6.0 and 7.5.
