Light Requirements
Salvia thermara thrives under full sun exposure, making it the perfect addition to your garden's sunny spots. However, it can also thrive under partial shade, but keep in mind that the plant's growth rate might be slower.
Temperature Requirements
Salvia thermara is native to South Africa and prefers warm temperatures. It can tolerate a wide range of temperatures, from 20°C to 35°C, but it may struggle to grow in temperature below 10°C. If you live in an area with cold weather, consider growing Salvia thermara in a greenhouse or warm indoor environment.
Soil Requirements
The plant can grow in a wide range of soils, but it prefers well-draining soils that are slightly acidic to neutral. It can tolerate sandy soils, loam, and clay, but make sure the soil is rich in organic matter. This will help the plant retain moisture and nutrients, allowing the roots to grow and expand. Keep the soil consistently moist, but ensure it isn't waterlogged, as this can hinder the plant's growth.
Cultivation Methods for Salvia thermara Van Jaarsv.
Salvia thermara Van Jaarsv. is commonly grown in well-draining soil. It thrives in full sun, but it can tolerate partial shade as well. These plants can thrive in USDA hardiness zones nine through eleven. It is often propagated from seeds, stem cuttings, or layering. To propagate from seed, seeds must be sown in a warm greenhouse in the spring. Once the seedlings have grown large enough to handle, they can be transplanted to individual pots.
Watering Needs for Salvia thermara Van Jaarsv.
The plant requires periodic watering for optimum growth, but it is intolerant of wet soils. Overwatering can cause root rot, so it is essential to maintain a careful balance. Depending on the weather, mature plants may require watering once a week. However, new plants may need watering more frequently. Before watering, check the soil to see if it is dry. Water the plants until the soil is moist but not soaked.
Fertilization for Salvia thermara Van Jaarsv.
Salvia thermara Van Jaarsv. responds well to regular feedings with a balanced fertilizer. Using a slow-release fertilizer can help ensure that the plant receives all the necessary nutrients. It is best to fertilize the plant in early spring and again in the summer, as the plant has two growing seasons. Always follow the instructions on the fertilizer package and avoid over-fertilizing, as it can harm the plant.
Pruning of Salvia thermara Van Jaarsv.
Pruning helps maintain the shape and size of the plant. Cutting back the plant can promote bushier growth. In early spring, prune the plant back to remove any winter damage. Deadhead regularly to promote the production of new flowers. After the plant has finished blooming, trim off the old flower stalks. In the fall, trim the plant back by about one-third to prevent excess growth over the winter.
Propagation methods of Salvia thermara Van Jaarsv.
Salvia thermara Van Jaarsv. can be propagated through various methods including seeds, stem cuttings, and division. However, the success rate of propagation may vary depending upon the method used.
Seeds propagation
The easiest way to propagating the Salvia thermara is through seeds. The seeds should be collected from the matured plant during the fall season. After harvesting, the seeds should be cleaned, dried, and stored in a cool and dry place. Just before planting, they should be scarified to allow better germination.
The seedlings should be grown indoor, and then after six months, it should be transplanted to the garden during the spring season.
Stem cutting propagation
Propagation of Salvia thermara by stem cutting can be done during the spring season. The stem cuttings should be around 7-10 cm long and taken from the healthy and matured plant. To create a healthy new plant, the cutting must have at least two nodes.
After taking the cutting, it should be dipped in a rooting hormone and well-drained potting soil. The newly planted stem cutting should be watered and put in bright sunlight, but with low intensity. During root development, humidity and temperature should be kept high.
Division propagation
To propagate Salvia thermara via division, the plant should be divided during its dormant state.
The plant should be dug out of its soil, and the roots should be separated. The new roots should be planted in well-drained potting soil and watered lightly.
After planting, the plant should be placed in bright but partial sunlight and kept moist. This method should not be used frequently and should be used only if the plant is a matured and big size.
Disease Management
Salvia thermara Van Jaarsv. is susceptible to several diseases, including powdery mildew, root rot, and bacterial blight. Powdery mildew appears as white, powdery spots on the upper leaves, while root rot causes wilting and yellowing of the leaves. Bacterial blight manifests as water-soaked lesions on the foliage.
To manage powdery mildew, remove and destroy infected leaves, provide good air circulation, and avoid overhead watering. Fungicides such as neem oil can be applied. For root rot, ensure that the soil is well-drained, and consider using fungicides containing copper hydroxide or thiophanate-methyl. Remove and destroy affected parts of the plant for bacterial blight and avoid overhead watering to reduce its spread.
Pest Management
Common pests that affect Salvia thermara Van Jaarsv. include spider mites, aphids, and whiteflies. Spider mites are tiny, sap-sucking insects that cause yellowing and stippling of the leaves. Aphids and whiteflies also suck sap and cause yellowing and wilting of the leaves.
To manage spider mites, use forceful sprays of water to remove them from the plant, and apply insecticidal soap or neem oil. Encourage natural predators such as ladybugs, lacewings, and predatory mites. For aphids and whiteflies, the same measures can be taken, but sticky traps can also be used to catch the insects before they infest the plant. Introducing parasitic wasps and ladybugs can help control these pests in a natural way.
