How to Care for the Plant

Water
This plant likes regular watering, preferably once or twice a week, especially during the summers. However, make sure to drain the soil completely. Whenever the top 2″ inches of the soil is dry, water it. The plants love a humid atmosphere and grow well in around 50% humidity.
Pruning
Black and blue sage is simple to prune. Once it’s through flowering, simply cut off the stems all the way to the ground. Prune once or twice a year after the flowers have died or faded.
Fertilizer
Only the container-grown plants require monthly fertilizer. In a garden, they require little fertilizer as an excess of it can reduce flower production.

Sunlight
Anise-scented sage requires full sun to partial shade to grow well. However, keep it under a sheltered, well-lit spot, preferably south-facing or west-facing. Avoid a north facing planting if possible.
Soil
They love rich, well-drained soil. Avoid poorly-drained soils as that can cause root rot. Go for sandy, chalky, and loamy soils with a slightly acidic pH of 5.5 – 6.5.
Temperature
It’s a winter hardy plant that grows well in USDA Hardiness Zones 8-10 and can tolerate heat.
