Cultivation of Gethyllis cavidens D.Müll.-Doblies
Gethyllis cavidens D.Müll.-Doblies, commonly known as the "Kukumakranka" plant, is an attractive plant that is easy to cultivate. It is a perennial plant that grows from a large underground corm, and it produces very beautiful star-shaped flowers that are pink or white in color. Here are a few tips for cultivating this lovely plant:
- Choose the right location: Gethyllis cavidens D.Müll.-Doblies should be planted in an area that receives full sun or partial shade. This plant also requires well-draining soil, so ensure that the area where you plant it has good drainage.
- Plant the corms correctly: Plant the corms about 10-15cm deep in the soil. Ensure that the flat side of the corm is facing downwards, and the growing point is facing upwards. It is advisable to plant at least two corms per hole to guarantee a higher survival rate.
- Use mulch: Adding a layer of organic mulch around the base of the plant helps to retain moisture, moderates soil temperature, and suppresses weed growth, which can be important for young plants.
- Protect from frost: Gethyllis cavidens D.Müll.-Doblies is sensitive to frost, so if you live in regions with extremely cold weather, you should cover the plant with a cloth to protect it during the winter months.
Watering and Fertilization Needs
To ensure the proper growth and development of Gethyllis cavidens D.Müll.-Doblies, it is essential to adequately provide it with water and nutrients. Here are a few tips for watering and fertilizing this plant:
- Watering: Water the plant deeply once or twice a week during the growing season. However, do not let the soil become waterlogged since it could cause rotting of the corms.
- Fertilization: To promote healthy growth and flowering, it is advisable to fertilize the plant with a balanced fertilizer. Apply a slow-release fertilizer during the growing season. Be cautious not to apply an excess of fertilizer since it can burn the roots of the plant.
Pruning
Gethyllis cavidens D.Müll.-Doblies is a plant that doesn't require very aggressive pruning. However, there are a few things you can do to maintain the health and good looks of the plant, like:
- Flower stalks: After the plant has finished flowering and the stalks have died down, you should carefully remove them to improve the plant's overall appearance.
- Dead leaves: To avoid fungal growth and pests, it is advisable to regularly remove dead leaves and any other organic debris around the base of the plant.
Propagation of Gethyllis cavidens
Gethyllis cavidens can be propagated through seeds or bulbs.
Seed propagation
The seeds of Gethyllis cavidens need to be sown in a well-draining soil mix that consists of equal parts of sand, peat, and loam. The seeds should be covered with a thin layer of the soil mix and kept moist. Germination typically takes between 1-2 months, and once the plants have developed their first set of true leaves, they can be transplanted to their final growing location.
Bulb propagation
Gethyllis cavidens also reproduces vegetatively through bulbs. Mature bulbs can be removed from the parent plant in the dormant season, typically in the late summer or early fall. The bulbs should be allowed to dry for a week or two before being planted in a well-draining soil mix. The bulbs can be planted with their tops just above the soil surface. The soil should be kept moist but not waterlogged until the bulbs start sprouting, which usually happens within a few weeks.
With proper care, both seed and bulb propagation methods can yield healthy and thriving Gethyllis cavidens plants.
