Salvia koyamae

Sage (Salvia koyamae) is a native Japanese perennial plant with a unique gray-green foliage. It has delicate white flowers, and is known for its drought tolerance, making it a great plant for xeriscape and dry rock gardens. This species of sage is also known for its winter hardiness and can survive temperatures up to -20 Celsius. With slow and steady growth, it remains compact for many years. Its robust and compact form makes it ideal for combining with other perennials and evergreens. Best of all, when blooming it creates a gentle and soothing scent.

watering

When watering Sage (Salvia koyamae), it is important to not over or under water. Sage likes soil that is slightly moist and well-draining. During its active growing season from March to June, water when the soil is dry to a depth of about 1 inch. Reduce the amount of water during the late summer months, as the plants can become less tolerant of the wet soil. In autumn, reduce the amount of water further as the plant will go dormant and will need less water. Water the sage only when the soil feels dry and avoid over-watering. In times of high heat and drought, it is important to water sage regularly to keep it from wilting. If temperatures become too hot, move the sage to a more shaded spot to reduce stress.

sunlight

Sage (Salvia koyamae) requires full sun to partial shade for proper growth. It grows best when placed in a location which receives at least 6-8 hours of direct sunlight each day. It is also tolerant of some shade, and can even tolerate periods of drought. Sage also benefits from regular watering, as long as the soil has adequate drainage. For optimum growth and health, it is best to water Sage deeply and infrequently, allowing the soil to dry out between waterings.

pruning

Sage (Salvia koyamae) typically requires annual pruning to keep its shape, maintain uniformity, and promote maximum growth. Pruning is best done in the spring or late summer after flowering. For this species, start by cutting up to 1-third of the older stems at ground level to encourage new growth. A similar amount of height can then be taken off any of the taller stems. Once established, Sage will require maintenance pruning. Dead or weak stems should be removed to allow the plant to remain healthy and promote strong robust growth. In late winter, Sage can also be lightly cut back to ensure healthy branching and encourage flowering in the spring.
