Overview
Mesembryanthemum goodiae (L.Bolus) N.E.Br. is a succulent plant that belongs to the family Aizoaceae. It is a low-growing, mat-forming species of mesemb that is endemic to South Africa.
Common names
The plant is commonly known as Good’s mesemb, trailing ice plant, and purple vygie.
Appearance
Mesembryanthemum goodiae features thick, fleshy, and succulent leaves that are gray-green in color. The leaves grow up to 40 mm long and are up to 20 mm wide. They are triangular to oblong-ovate in shape and are slightly curved downwards.
The flowers of this plant are star-shaped and appear at the top of the stems. They typically bloom from mid-spring to early summer. The flowers have a range of bright colors, including pink, purple, and white.
Uses
Mesembryanthemum goodiae is a popular choice for landscaping purposes because of its beautiful and vibrant flowers. It is great for adding a splash of color to rock gardens, borders, and other garden areas. This species is also useful for erosion control as it has a shallow root system that can help stabilize the soil.
Light Requirements
Mesembryanthemum goodiae typically grows best in full sun to partial shade conditions, requiring at least six hours of direct sunlight a day. The plant may survive in low light conditions, but it may have reduced flowering and growth rate.
Temperature Requirements
The plant is native to South Africa and is well adapted to hot and dry conditions. A temperature range of 60°F to 85°F (15°C to 30°C) is suitable for its growth. However, the plant may not survive frost and prefers a warmer climate.
Soil Requirements
The plant grows well in well-drained, sandy soil with a pH range of 6.5 to 7.5. Soil with good aeration and drainage is essential to prevent waterlogging, which can cause root rot and hinder the plant's growth. The plant also prefers soil with low to moderate fertility and benefits from occasional applications of fertilizer.
Cultivation
Mesembryanthemum goodiae is a succulent plant that grows well in well-draining soil. A sandy cactus mix is ideal for its growth as it mimics its natural desert habitat. It requires a lot of sun exposure, so placing the plant in direct sunlight or a bright area for at least 4 hours a day is essential. The plant is frost-sensitive and should not be kept in temperatures below 50 degrees Fahrenheit.
Watering Needs
The plant is drought-tolerant. Water it only when the soil is dry, which may range from once a week to once a month depending on the temperature and the humidity in the environment. Overwatering can lead to root rot and other fungal or bacterial infections. When watering, ensure that all the soil is moistened and the excess water is drained out.
Fertilization
Mesembryanthemum goodiae does not require frequent fertilization. Use a slow-release fertilizer once a month during the growing season, which typically runs from Spring to Fall. The fertilizer should be diluted to half of the recommended strength to avoid damaging the plant. Too much fertilizer can also alter the color and texture of the leaves and flowers, making them less appealing.
Pruning
Mesembryanthemum goodiae does not require frequent pruning, but trimming the plant periodically helps it maintain its shape and promotes healthy growth. Pinch off any wilted or dead flowers or leaves to avoid attracting pests or diseases to the plant. Use sterilized scissors or garden shears to cut back any overgrown branches. Avoid pruning the plant during the Winter season when it is dormant.
Propagation of Mesembryanthemum goodiae
Mesembryanthemum goodiae can be propagated through seeds, stem cuttings, or division of clumps. Here are the details of each method:
Propagation by Seeds
The seeds of Mesembryanthemum goodiae can be sown in late winter or early spring. The seeds are very small, so they need to be sown on the surface of the soil or lightly covered with sand. The soil should be well-draining and kept moist until the seeds germinate.
Once the seedlings develop their first leaves, they can be transplanted into individual pots. The young plants should be kept in a warm and bright location and watered sparingly to prevent root rot. After the last frost, the plants can be planted outside in a sunny and well-draining spot.
Propagation by Stem Cuttings
Mesembryanthemum goodiae can also be propagated by stem cuttings. The cuttings should be taken in spring or summer when the plant is actively growing. The stem cuttings should be around 10cm long and taken from the tip of the plant.
Remove any flowers or buds from the cutting and let it dry for a day or two. Dip the cut end in rooting hormone and plant it in a well-draining soil mix. Keep the cutting in a warm and bright location and water it sparingly until roots form.
Propagation by Division of Clumps
Mesembryanthemum goodiae forms clumps as it grows, and these clumps can be divided and replanted. The best time to divide the clumps is in the spring, just before the plant starts actively growing.
Dig up the clump and gently separate the individual plants. Each plant should have an intact root system and at least two leaves. Replant the individual plants in a well-draining soil mix and keep them in a warm and bright location. Water the young plants sparingly until they establish roots.
Disease and Pest Management for Mesembryanthemum goodiae
Mesembryanthemum goodiae is a hardy and drought-tolerant plant that is generally resistant to most diseases and pests. However, in certain circumstances, the plant might succumb to some common diseases and pests.
Common Diseases
The most common diseases that affect Mesembryanthemum goodiae are fungal in nature. Gray mold and powdery mildew are the most frequently occurring diseases in this plant. Gray mold appears as a grayish-brown, fuzzy growth on the leaves, stems, and flowers of the plant. Powdery mildew, on the other hand, causes a powdery, white growth on the plant's above-ground parts.
Pest Infestation
Mesembryanthemum goodiae is susceptible to a few pests, like spider mites, aphids, and mealybugs. Spider mites cause yellowing and stippling of the leaves, while aphids and mealybugs damage the plant by sucking its sap. These pests are relatively easy to control if detected early.
Disease and Pest Management
The following are some of the ways to manage diseases and pests in Mesembryanthemum goodiae:
1. Cultural Control: Maintaining proper cultural practices like watering the plant at the base, avoiding overcrowding, and ensuring proper air circulation can help prevent or minimize disease and pest incidences.
2. Chemical Control: Fungicides can help control fungal diseases like gray mold and powdery mildew. Insecticidal soaps and oils can effectively control pests like spider mites, aphids, and mealybugs. It's essential to use the correct products and follow the instructions carefully to prevent further damage to the plant.
3. Biological Control: Introducing predatory insects like ladybugs, lacewings, and parasitic wasps can help control pest populations in a natural way. Some beneficial fungi like Trichoderma and Beauveria spp can also control fungal diseases to some extent.
To conclude, a healthy Mesembryanthemum goodiae plant is generally resistant to most diseases and pests. Regular inspections and early intervention can prevent further damage to the plant and ensure its growth and development.
