Autumn sage works well in containers, borders, or mass plantings. The branches originate near the base of the plant resulting in a vase-shaped appearance. Small 1-inch flowers from spring through fall. It tolerates heat and requires little supplemental water after the plant is established. The historically red-flowered plant has been enhanced, and varieties of colors are now available. Salvia is adaptable to many garden soils and is attractive to both hummingbirds and butterflies.
Light
For your Autumn Sage plant to bloom to its potential, it needs about six hours a day of full sun.
Soil
Soil should be rich and well-drained for best bloom.
Water
New plants will need water to establish, so make sure they are adequately watered. A small plant with fewer leaves needs less water than a large leafy plant in full bloom. Through summer, give your sage a deep soak twice per week. This can be cut back to once per week if a monsoon rain occurs. You should water this plant twice per month in winter or when the soil is dry to the touch.
Fertilizer
Growing Autumn Sage needs plenty of nutrients. Feed with 7-4-4 All Purpose Food three times per year for amazing flowers. This natural food is spread like salt-and-pepper around the plant's base every Easter, July 4th, and Halloween for incredible results.
