Adromischus schonlandii (E.Phillips) Poelln.
Adromischus schonlandii is a species of succulent plant in the Crassulaceae family, originally described by Edwin Percy Phillips in 1916 as Cotyledon schonlandii and later transferred to the genus Adromischus by Karl August Poellnitz in 1936. It is native to the Eastern Cape Province of South Africa, and is commonly found in rocky crevices and on steep slopes in arid regions.
Common Names
The common names of Adromischus schonlandii include ‘Schonland’s adromischus’, ‘candelabra plant’, ‘pearl plant’ and ‘pickle plant’. The latter two names refer to the plant’s small, round and plump leaves that are covered in tiny white bumps, giving them the appearance of pearls or pickles.
Appearance
Adromischus schonlandii is a small, slow-growing succulent plant that typically grows up to 8cm in height and forms a stemless rosette of fleshy, ovate to lanceolate leaves. The leaves are light green in color and have a noticeable flap at the tip, which helps to distinguish the plant from other species of Adromischus. The white bumps on the surface of the leaves are actually small, warty protuberances that contribute to the plant’s unique texture and appearance.
Uses
Adromischus schonlandii is largely grown as an ornamental plant for its attractive appearance and unusual texture. It is commonly kept in containers or rock gardens, where its drought-tolerance and low maintenance requirements make it a popular choice for novice gardeners. In its native South Africa, Adromischus schonlandii has traditionally been used in traditional medicine to treat a range of ailments such as fevers, stomach complaints, and insect bites.
Light Requirements
Adromischus schonlandii is a succulent plant that grows best in bright, indirect light. It does not tolerate direct sunlight for extended periods, particularly if temperatures are high. Therefore, it is advisable to place the plant in a location that receives partial to full shade for most of the day. Providing adequate light helps ensure that the plant maintains its attractive foliage color and shape.
Temperature Requirements
Adromischus schonlandii grows well in moderate temperatures, between 60°F and 80°F (15.6°C – 26.7°C). It is essential to note that this plant is intolerant of temperatures below 50°F (10°C) and will start to show signs of frost damage and leaf discoloration. It is also susceptible to extreme heat, particularly when exposed to temperatures above 90°F (32°C), which can cause leaf burn and eventual wilting.
Soil Requirements
Adromischus schonlandii requires a well-draining soil mix to thrive. It thrives in soil that has added perlite, sand, or pumice, which helps improve drainage. The soil pH should range between 6.0-7.0, which is mildly acidic. It is also advisable to allow the soil to dry out completely between watering to prevent root rot. Watering should be done moderately during the growing season and reduced in winter. Additionally, fertilizers should be applied sparingly since the plant is sensitive to excess salts.
Cultivation Methods for Adromischus schonlandii
Adromischus schonlandii is a succulent plant that is relatively easy to cultivate and care for. It is a slow-growing plant that requires minimal attention once it has adapted to its growing conditions. This plant is best grown in a well-draining soil mix that is specially formulated for succulents.
It is ideally grown in a pot that has a drainage hole to prevent waterlogging of the soil. Adromischus schonlandii enjoys bright light but can also tolerate partial shade. It is suitable for growing both indoor and outdoor in a warm climate.
Watering Needs for Adromischus schonlandii
When it comes to watering Adromischus schonlandii, it is essential to avoid overwatering, as it can lead to root rot. It is best to water the plant when the soil is completely dry, which is usually once every two weeks in the summer and once every month in the winter.
Ensure that the water reaches the soil's roots and not just the plant's leaves or stems. Watering from the bottom can help to prevent excess moisture from settling on the leaves, which can lead to fungal infections.
Fertilization of Adromischus schonlandii
To ensure that Adromischus schonlandii remains healthy and vibrant, it requires fertilization during the growing season. It is best to use a low-nitrogen succulent fertilizer that is specially formulated for such plants.
Avoid fertilizing the plant during the dormant season, as this can lead to unnecessary growth that may weaken the plant. Fertilize the plant once a month in the growing season, following the manufacturer's instructions to avoid overfeeding it.
Pruning of Adromischus schonlandii
Adromischus schonlandii doesn't require frequent pruning, but occasional grooming can improve its appearance. Remove any dead, diseased, or yellowing leaves regularly to prevent the spread of diseases.
To maintain the desired shape of the plant, pinch off new growth at the tips. You can also trim any leggy or elongated stems to encourage branching for a fuller look. Avoid over-pruning, as the plant may take a long time to recover.
Propagation of Adromischus schonlandii
The plant Adromischus schonlandii is a succulent that belongs to the Crassulaceae family. It is native to South Africa and is known for its beautiful, green, and upright leaves, which grow in compact rosettes. The plant can be propagated by different methods like:
Leaf cuttings
This is the most common method of propagating Adromischus schonlandii. Take a healthy leaf from the parent plant and let it dry for a few days before inserting it into a well-draining soil mixture. Keep the soil slightly moist and place the container in a bright and warm location. The leaf will produce roots and eventually, a small rosette will emerge.
Stem cuttings
Another method of propagation is through stem cuttings. Take a stem from the parent plant and let it dry for a few days. Dip the cut end in rooting hormone and plant it in a well-draining soil mixture. Keep the soil slightly moist and place the container in a bright and warm location. The stem will produce roots, and eventually, a new plant will emerge.
Division
Adromischus schonlandii can also be propagated through division. Carefully remove the plant from its container and divide the root ball into two or more portions. Replant each portion in a well-draining soil mixture and keep the soil slightly moist. Place the containers in a bright and warm location. The plants will grow and fill out their containers over time.
Seeds
Adromischus schonlandii can also be propagated through seeds. Sow the seeds in a well-draining soil mixture and keep the soil slightly moist. Place the container in a bright and warm location. The seeds will germinate in a few weeks, and the young plants can be transferred to their own containers once they are large enough to handle.
These are the four common methods of propagating Adromischus schonlandii. Whichever method you choose, always ensure that the soil is well-draining and the plant receives enough light and warmth to thrive.
Disease and Pest Management for Adromischus Schonlandii
Adromischus schonlandii is a popular plant due to its striking foliage that varies from shades of green to purple. However, just like any other plant, it is prone to diseases and pests that can negatively affect its growth and appearance. Here are some common diseases and pests that might affect Adromischus schonlandii and how to manage them:
Diseases
1. Root Rot
Root rot is a fungal disease that affects the roots of plants, making them mushy and black. It is caused by overwatering and poor drainage. To manage root rot, remove the affected parts of the plant and repot it in a well-draining soil mixture. Ensure that the pot has drainage holes and that you allow the soil to dry between watering.
2. Leaf Spots
Leaf spots are caused by fungi, bacteria, or viruses and appear as small circular or irregular spots on the leaves. They weaken the plant by interfering with photosynthesis. To manage leaf spots, remove and destroy affected leaves as soon as you notice the spots. Maintain good air circulation around the plant, avoid getting water on the leaves, and ensure that you do not overcrowd the plant.
Pests
1. Mealybugs
Mealybugs are small, white, fluffy bugs that infest the foliage and stems of Adromischus schonlandii. They suck sap from the plant, leading to stunted growth and yellowing of the leaves. To manage mealybugs, wipe them off with a cotton swab dipped in rubbing alcohol or insecticidal soap. You can also use neem oil to smother them.
2. Spider Mites
Spider mites are tiny, spider-like pests that infest the leaves, sucking sap and causing yellowing and wilting. They are prevalent in dry environments. To manage spider mites, increase humidity levels around the plant by misting it regularly. You can also wipe the leaves down with a damp cloth or spray insecticidal soap.
By taking proper care of your Adromischus schonlandii and monitoring for any signs of disease or pest infestation, you can ensure that your plant remains healthy and vibrant.
