Cultivation Methods for Salvia lanceolata Lam.
Salvia lanceolata Lam. is as tolerant as it is hardy, able to grow in conditions ranging from full sun to partial shade, and able to thrive in a range of soils. However, for best results in cultivation, it is recommended to grow them in slightly acidic to neutral soils with pH values between 6.0 and 7.2. The plant does not require highly fertile soils, but satisfactory drainage conditions are necessary for their growth. The plant grows to a maximum height of 60 cm and can spread up to 45 cm in diameter.
Watering Needs for Salvia lanceolata Lam.
Salvia lanceolata Lam. is drought-tolerant and can withstand long, dry spells, providing the soil is well-drained. However, it is advisable to water the plant regularly during the growing season, especially in areas with hot and dry climates, as it can help to hasten the growth of the plant.
Fertilization of Salvia lanceolata Lam.
Salvia lanceolata Lam. is a moderate feeder, and as such, regular fertilization can enhance its growth and overall appearance. To keep the plant at its best, an all-purpose fertilizer can be applied once every two or three weeks during the growing season. This can be done either by scattering the fertilizer around the base of the plant or by diluting the fertilizer in water and then watering the plant.
Pruning Salvia lanceolata Lam.
Pruning Salvia lanceolata Lam. is necessary to keep the plant neat and healthy. When flowering is over, the spent flower spikes should be removed immediately to encourage the growth of new spikes. Also, any dead or rotting leaves or stems should be trimmed as they appear. The plant should be cut back to about a third of its height every autumn, after blooming has finished.
Propagation methods of Salvia lanceolata Lam.
The plant Salvia lanceolata Lam., commonly known as lance-leaved sage, can be propagated through various methods depending on the desired outcome. These methods include:
Seed propagation
The most common method of propagating Salvia lanceolata is through seeds. The seeds can be collected from the plant when they start to mature and turn brown. The seeds should be sown in early spring, either in trays or directly in the ground.
When sowing in trays, the seeds should be sown at a depth of 1-2mm, and the trays should be kept in a warm, well-lit place. The seedlings should be pricked out into individual pots when they are large enough to handle, and they should be kept in a sheltered spot until they are big enough to plant in their final position.
When sowing directly in the ground, the soil should be prepared by removing weeds and stones and adding compost or well-rotted manure. The surface of the soil should be raked over, and the seeds should be sown thinly. The soil should be watered and kept moist until the seedlings emerge.
Cuttings
Salvia lanceolata can also be propagated through softwood cuttings taken in early summer. Cuttings should be taken from young, actively growing shoots, and they should be about 8-10cm long. The bottom of the cutting should be dipped in rooting hormone, and it should be planted in a well-draining soil mix. The cuttings should be kept in a warm, sheltered spot and watered regularly until they have rooted.
Division
The third method of propagating Salvia lanceolata is through division. This is done by digging up mature plants and dividing the rootball into smaller sections, each with a healthy shoot or two. The divided plants should be replanted in well-prepared soil and watered well until they are established.
