Soil requirements
The Salvia subincisa Benth. plant prefers well-drained soils that are rich in organic matter. The ideal pH range for this plant is between 5.5 to 7.5. The soil should also be evenly moist and not waterlogged. Good drainage is important because this plant is susceptible to root rot.
Cultivation Methods
Salvia subincisa Benth. is a hardy plant that thrives in well-draining soils, and it is recommended to plant it in a location with good sun exposure. The plant can be easily propagated from cuttings, and it is advisable to do so in the spring to ensure faster and more successful growth.
Watering Needs
In general, Salvia subincisa Benth. requires moderate watering. The plant prefers to be watered when its topsoil is dry, and it is recommended to avoid overwatering to prevent root rot. During the hot summer season, it may require more frequent watering to keep the soil moist, but make sure not to water excessively.
Fertilization
Salvia subincisa Benth. does not require much fertilization and thrives in a nutrient-poor environment. However, adding a slow-release fertilizer once or twice annually can help promote healthy growth and vigorous blooms. Avoid feeding the plant excessively, which can lead to the development of weak and lanky growth.
Pruning
Regular pruning will help rejuvenate an aging plant, promote bushier growth, and encourage the plant to produce more flowers. When pruning, cut back to a node or where a branch or leaf emerges from the stem. Deadheading is also recommended to remove wilted blooms and encourage more flower production.
Propagation of Salvia subincisa Benth.
Salvia subincisa Benth., commonly known as Yunnan Sage, is a herbaceous perennial plant belonging to the mint family (Lamiaceae). It originates from Yunnan Province in China, and has attractive pinkish-red flowers and aromatic foliage. Propagation of this plant is best done through division, cuttings, or seeds.
Division
Propagation of Salvia subincisa through division is best done either in early spring or fall. Carefully dig up the mature plant and separate the root ball into several sections with a sharp and clean knife. Each section should have at least one vigorous shoot and some roots. Transplant the sections into their preferred location, and water them well.
Cuttings
Propagation through cuttings is a common method of cloning plants, especially in commercial nurseries. Salvia subincisa can be propagated through softwood or semi-hardwood cuttings. Softwood cuttings can be taken in early summer while semi-hardwood cuttings are taken in late summer or early fall. Take a 6-inch cutting with at least two nodes and remove the leaves on the lower half of the cutting. Dip the cut end into rooting hormone, and then plant it in a well-draining soil mixture. Keep the cutting moist, and place it in a warm and bright location that is protected from direct sunlight till roots form.
Seeds
Propagation through seeds is a reliable method but it requires some patience. Salvia subincisa seeds can be sown in either early spring or autumn. Sow the seeds about 1/8th inch deep in a well-draining soil mixture and cover them with plastic wrap or a clear plastic lid to retain moisture. Place the container in a bright location that is protected from direct sunlight, and keep the soil moist. The seeds germinate in two to three weeks, and the seedlings should be transplanted to their permanent location after the last frost.
