How to Fertilize a Furman Red Sage Plant

Overview

Furman red sage is a variety of the Salvia greggii species of perennial herbs. It is a true red-blooming variety (hence its name) and it grows in a wide array of soil, temperature and moisture conditions, making it an easy-care plant. It grows in a small woody shrub form that flowers from June through October and sometimes longer in temperate or warm climates. Once-a-year feeding and organic soil amendments will keep the plants healthy and blooming.

Step 1

Add a slow release fertilizer to the planting soil around your Red Furman sage at planting time. Select a complete and balanced formulation with a guaranteed analysis of 10-10-10. Use the dose recommended on the product label and till it into the planting soil to a depth of 6 inches, distributing the granules evenly in the soil.

Step 2

Feed your Red Furman sage once a year in the spring with the same slow-release granular fertilizer. Follow the recommended dosing on the product label and do not exceed three pounds of fertilizer for every 100 square feet. Sprinkle the granules equally around the root ball of the plant keeping a few inches out from the main stems. Nestle the fertilizer into the top inch of soil and water in well.

Step 3

Topdress the soil over the fertilizer each spring with a few pounds of compost and/or well-aged livestock manure. This will enrich the soil and feed the sage plants in addition to serving as mulch to hold moisture and keep competitive weeds from cropping up. Water in the top dressing to settle it into the soil.
