Cultivation Methods
Senecio salviifolius Sch.Bip. or silver ragwort is best grown in well-drained soil that is rich in organic matter. It requires full sun exposure for the better part of the day and can tolerate a wide range of soil pH values.
When starting from seeds, the seeds should be sown in spring or early summer. Cover the seeds lightly with soil and keep the soil moist until the seeds germinate. At the seedling stage, it is recommended to provide ample light to ensure sturdy growth.
For propagation by terminal cuttings, cut a 3-inch stem just below a leaf node and remove the lower leaves. Place the cutting in a moist, well-drained rooting medium and cover with plastic to maintain high humidity. The cutting should develop roots within 2-4 weeks.
Watering Needs
Senecio salviifolius Sch.Bip. needs regular watering but should not be over-watered. It does not tolerate water-logged soil and should be watered only when the soil is dry to the touch. Established plants should be watered deeply once or twice a week.
Drought conditions can lead to leaf drop and stunted growth. On the other hand, overwatering can cause root rot and can weaken the plant.
Fertilization
Senecio salviifolius Sch.Bip. does not require frequent fertilization. It can be fertilized in early spring using a balanced, slow-release fertilizer of 10-10-10 NPK. However, too much fertilizer can cause excessive growth and weak plants.
It is advisable to provide additional fertilization in case of stunted growth, yellowing of leaves, or poor production of flowers. Organic fertilizers such as compost can also be applied in moderation since too much organic matter can lead to root rot.
Pruning
To promote bushy growth and to prevent legginess, Senecio salviifolius Sch.Bip. should be pruned once or twice a year. Prune the plant in early spring before new growth appears and again in late summer after flowering.
Remove dead or diseased stems and yellowing leaves. Also, cut back more than half of the plant's height to encourage new branching. Pruning should be done using a clean and sharp pair of garden shears.
Propagation Methods of Senecio salviifolius Sch.Bip.
Senecio salviifolius Sch.Bip. is a popular plant species because of its drought tolerance, making it suitable for arid and semi-arid regions. The plant can be propagated through various methods as described below:
Seed Propagation
The plant's seeds can be collected from the mature dried seed heads. The collected seeds are then soaked in water overnight to stimulate germination. Sowing then follows in a propagator or seed tray filled with a free-draining medium like sand or compost. Then, place the propagator in a warm spot where temperature does not fall below 15°C.
Seedlings should emerge between one to three weeks of sowing. Once the seedlings are established, transfer them into individual pots that suit their size until they grow into mature plants.
Cuttings Propagation
One way to propagate Senecio salviifolius Sch.Bip. is through taking cuttings during the growing season. The cuttings should be 10cm long and from the stem's growing tip. Remove the lower leaves and dip the cuttings in rooting powder to help stimulate their rooting.
Then, insert the stems into a free-draining compost mix and cover them with a plastic bag to maintain moisture and humidity. Ensure they are not exposed to direct sunlight, and the temperature is consistently above 15°C. It takes around 4-6 weeks for the cuttings to establish roots, and they can then be planted in individual pots of suitable size.
Division Propagation
The plant can also be propagated by division during spring when it starts to develop new growth. Carefully dig out the plant clump and remove excess soil to identify the new shoots' base. Use a sterilized knife to divide the clump and ensure that each division has roots attached to it.
Plant each division in a pot with suitable size, ensuring the soil surface is at the same level as the plant's top. Water thoroughly and add some fertilizers to encourage root growth. Put the pot in a sunny and warm location and ensure moisture is kept at an optimum level.
These are the three methods suitable for the propagation of Senecio salviifolius Sch.Bip. Choose the method that's most convenient for you and get propagating.
