Straight A® Barley Blue Agapanthus

1. Planting: Agapanthus plants thrives in average moisture and well-drained soil. They prefer full sun to partial shade, requiring 6 to 8 hours of sunlight daily, and are not picky about soil type or pH. 

Plant rhizomes 2 inches deep and 12 to 18 inches apart with the pointed end facing up, adding mulch for winter protection. For potted agapanthus, plant 1 inch deep and 8 inches apart in a fertile, well-draining mix in a container with drainage holes. A 12-inch pot works for one plant, but they bloom best when pot-bound.

2. Watering: Water regularly until established. It prefers average to moist conditions and should not be allowed to dry out. During periods of drought or extended heat, supplemental watering may be necessary.

3. Fertilizing: A thick layer of mulch helps to retain soil moisture and insulate the root system from temperature extremes. Fertilize in spring, then again two months later.

4. Pruning: Prune in late autumn. This plant requires occasional maintenance and should be cleaned up in early spring before it resumes active growth for the season.
