Growth Conditions for Senecio glutinosus E.Mey.
Senecio glutinosus E.Mey., commonly known as sticky groundsel, is a species of flowering plant that belongs to the family Asteraceae. It is a small, herbaceous subshrub that typically grows up to 40 cm in height. Sticky groundsel is native to South Africa but can be found in many other regions of the world, such as Australia, New Zealand, and North America.
Light Requirements
Sticky groundsel is a sun-loving plant and requires full or partial sunlight to grow successfully. It thrives in areas that receive plenty of sunlight and does not tolerate shade. Therefore, it is essential to plant sticky groundsel in an area where it can get at least six hours of direct sunlight per day.
Temperature Requirements
Sticky groundsel prefers warm temperatures and can thrive in a wide range of temperatures. It can tolerate temperatures as low as -4°C (25°F) and as high as 38°C (100°F). However, it cannot tolerate extreme cold or heat, and therefore, should be protected from frost and excessive heat.
Soil Requirements
Sticky groundsel grows well in well-draining soils with a slightly acidic to neutral pH. It prefers loamy soils that are rich in organic matter and can retain moisture. It does not tolerate water-logged soils and can suffer from root rot if planted in such conditions. Sandy soils are not ideal for sticky groundsel as they do not retain water or nutrients, which can lead to stunted growth.
Overall, sticky groundsel is a hardy plant that can tolerate a wide range of growing conditions. However, providing it with the right amount of light, appropriate temperature, and well-draining, nutrient-rich soil can help it grow more robustly and produce more flowers.
Cultivation Methods
Senecio glutinosus E.Mey. is a hardy perennial that thrives in a sunny position and well-draining soil. It can be propagated by seeds or cuttings. When growing from seeds, sow them in the early spring in trays filled with seed compost, and keep them moist. When the seedlings reach a height of about 2cm, transfer them to individual pots, and keep them in a protected area until they are large enough to be transplanted into their final position.
If you wish to propagate from cuttings, select healthy young growth and take cuttings in the spring or summer. Dip the cut end into hormone rooting powder, and insert it into moist potting soil. Keep the soil moist and the cutting in a protected area until roots are established.
Watering Needs
Senecio glutinosus E.Mey. prefers consistent soil moisture that is not too wet or too dry. In the growing season, it is vital to keep the soil moist but not waterlogged. During the winter months, watering can be less frequent, but the plants should not be allowed to dry out completely. It's best to water early in the day or late in the evening to avoid evaporation during the hottest part of the day.
Fertilization
Senecio glutinosus E.Mey. does not require a lot of fertilization. You can feed your plant with a well-balanced fertilizer once a month during the growing season. Over-fertilization should be avoided, as it can lead to excessive foliage growth but minimal flower production.
Pruning
To promote bushy growth and increase flower production, Senecio glutinosus E.Mey. can be pruned in late winter or early spring. Cut back about one-third of the plant's height, and remove any dead, damaged, or crossing branches. It's also essential to remove spent flower heads promptly to encourage continuous blooming.
Propagation of Senecio glutinosus E.Mey.
Senecio glutinosus E.Mey. is a drought-tolerant and easy-to-grow perennial plant that can be readily propagated by various methods. The following are some of the most common propagation techniques:
Seed Propagation
Seeds of Senecio glutinosus E.Mey. can be sown directly into a well-draining potting mix in the spring. Prior to sowing, it is recommended to sow the seeds on top of the soil and not cover them, as they require light for germination. The seeds will germinate in 2-3 weeks if the temperature is maintained at 15-20°C. Once seedlings appear, they can be transplanted into individual pots until they reach maturity.
Cuttings Propagation
Senecio glutinosus E.Mey. can also be propagated by cuttings. Take stem cuttings of at least 10cm in length, making sure they have a few leaves attached to them. Remove the lower leaves off the cutting, and dip the cut end in rooting hormone. Then, plant the cutting in a well-draining potting mix, and water it frequently until roots appear, which usually takes about 3-4 weeks. Once the roots have developed, the plant can be transplanted into a bigger pot or planted directly in the ground.
Division Propagation
It is possible to propagate Senecio glutinosus E.Mey. using the division method, which is best done in the spring or fall. First, remove the plant from its pot or the ground and gently shake off the excess soil. Then use a sharp knife or scissors to divide the plant into smaller sections, making sure that each division has roots and shoots. Finally, plant each division in a well-draining potting mix and water it regularly until it establishes.
Disease and Pest Management for Senecio glutinosus E.Mey.
Senecio glutinosus E.Mey. is a robust and easy-to-grow plant species. However, like all plants, it is susceptible to some diseases and pests. Here are some common ones and how to manage them.
Diseases
1. Powdery mildew: Powdery mildew is a fungal disease that can cause the leaves to become covered in a white fungal growth. To manage this disease, it is essential to maintain good air circulation by spacing plants appropriately and avoiding overhead watering. Regularly inspecting the plants and removing infected leaves can also help prevent the spread of the disease.
2. Root rot: Root rot is a fungal disease that affects the roots of plants. It can cause yellowing of the leaves and stunted growth. To prevent root rot, it is essential to ensure that the soil has good drainage. Avoid overwatering and ensure that pots have drainage holes. If your plant is already infected, consider using a fungicide to manage the disease.
3. Grey mould: Grey mould is a fungal disease that can cause the leaves to become brown and mushy. This disease thrives in damp, humid conditions. To prevent grey mould from infecting your plant, ensure that soil is not too wet, keep foliage dry and water the plants early in the morning. Ensure proper air-circulation around the plants to reduce humidity.
Pests
1. Aphids: Aphids are small, soft-bodied insects that can cause stunted growth, curling and distortion of foliage. To manage aphids, you can gently wash the plant with water or using insecticidal soaps, horticultural oil or natural predators like lady beetles, lacewings, and syrphid flies.
2. Spider Mites: Spider mites are tiny insects that can damage foliage, leaving behind a stippled appearance. To manage spider mites, you can spray the plants with a jet of water or use insecticidal soap, horticultural oil or acaricides. Proper humidity and regular cleaning of the leaves also help manage the pest.
3. Mealybugs: These soft-bodied insects can cause yellowing of leaves, leaf drop, and stunted growth. To manage mealybugs, one can remove the bugs with a small brush, spray alcohol, or insecticidal soap. Horticultural oil or neem-based products are also an option. Regular inspection of plants is essential to detect infestations early.
Senecio glutinosus E.Mey. is a rewarding plant to add to your garden or houseplant collection. With proper care and management, one can avoid most diseases and pests.
