Senecio longeligulatus De Wild. can tolerate occasional dry spells and is not overly sensitive to soil fertility. However, it performs better in nutrient-rich soil supplemented with organic matter.
Cultivation of Senecio longeligulatus De Wild.
Senecio longeligulatus De Wild. is indigenous to sub-Saharan Africa, where it grows under warm and dry conditions. It prefers sandy or loamy, well-draining soil that allows water to pass through easily. It's recommended to plant in the spring and summer when the temperature is warm enough for optimal growth.
Watering Needs of Senecio longeligulatus De Wild.
Senecio longeligulatus De Wild. thrives on low to moderate watering. Overwatering of this plant can lead to root rot and cause the plant to wilt or die. It's recommended to water the plant once every two weeks, depending on the temperature and humidity of the surroundings. Keeping the soil slightly moist provides the plant with sufficient water without causing damage to the roots.
Fertilization of Senecio longeligulatus De Wild.
Senecio longeligulatus De Wild. is a low-maintenance plant that requires minimal fertilization. During the growing season, from spring to summer, it's recommended to fertilize the plant once a month with a balanced fertilizer. Do not fertilize the plant during winter, as it's a dormant period for the plant.
Pruning Senecio longeligulatus De Wild.
Pruning Senecio longeligulatus De Wild. helps to maintain its shape and promote new growth. It's best to prune the plant during the active growth period, which is spring and summer, as it allows for faster recovery. Cut back the stems to the desired size and shape, making sure to use clean and sharp pruning shears to prevent damage to the plant.
Propagation of Senecio longiligulatus De Wild.
Senecio longiligulatus De Wild. can be propagated through different methods such as seeds, cuttings and division.
Propagation through Seeds
The easiest way to propagate Senecio longiligulatus De Wild. is through seeds. To do this, you need to collect the ripe seeds from the plant. Sow the seeds in a well-draining soil mix and cover them lightly with soil. Water the soil well and place it in a warm and bright location. Germination usually occurs within two weeks, and the plant can reach maturity within six months to one year.
Propagation through Cuttings
Another way to propagate Senecio longiligulatus De Wild. is through stem cuttings. Take a stem cutting that is about 10 cm long, remove the lower leaves, and dip it in rooting hormone. Place the cutting in a well-draining soil mix and water it well. If you want to increase the success rate, it is best to keep the cutting in a humid environment by placing a plastic bag over the cutting. Keep the soil moist but not waterlogged, and in a bright area, but not in direct sunlight. After a few weeks, the cutting should have developed roots and can be transplanted to a larger pot.
Propagation through Division
Senecio longiligulatus De Wild. can also be propagated through division. To do this, carefully remove the plant from its pot, and divide the stems and roots into smaller sections using a sharp knife or scissors. Each section should have a good amount of roots and foliage. Re-pot the sections, water them well, and place them in a bright location. It is best to divide the plant during its growing season, which is typically in the spring and summer months.
