Umbilicus horizontalis (Guss.) DC. grows best in partial to full shade. Direct sunlight exposure can cause the plant to wilt and dry out quickly. In its natural habitat, the plant can be found growing in the understory of forests or on rock walls where it is shaded by larger plants or rocks.
Temperature Preferences
The plant prefers cool to mild temperatures and does not tolerate extreme heat or cold well. The ideal temperature range for Umbilicus horizontalis (Guss.) DC. is between 10°C to 25°C. If temperatures rise above this range, the plant may become stressed and wilt. In areas where temperatures drop below freezing, the plant may go dormant or die back in winter.
Soil Requirements
The plant prefers well-draining, sandy or loamy soil that is rich in organic matter. Umbilicus horizontalis (Guss.) DC. can tolerate a wide range of soil pH levels, but prefers slightly acidic to neutral soil (pH 6.0 to 7.0). The plant can grow in shallow or rocky soil as long as there is adequate drainage to prevent waterlogging. Additionally, the plant benefits from occasional fertilization with a balanced, all-purpose fertilizer to support growth and development.
Cultivation Methods
The Umbilicus horizontalis plant is a succulent that grows well in well-drained soil. To cultivate this plant successfully, make sure to provide it with a sandy substrate mixed with perlite or another draining agent. The soil's pH should range between 6.0 and 7.0. Keep it in a sunny location, and if growing indoors, place it near a sunny window.
Watering Needs
Like most succulents, the Umbilicus horizontalis does not need frequent watering. Water only when the soil has completely dried out, usually every one to two weeks in summers and every three weeks in winters. Be careful not to let the plant sit in standing water since it can cause root rot.
Fertilization
While Umbilicus horizontalis plants can survive without a fertilizer, providing them some nutrients can help them thrive. You can feed this plant with a well-balanced fertilizer once every three to four months during its growing season. Avoid over-fertilizing as it can harm the plant's roots.
Pruning
Pruning is not necessary for the Umbilicus horizontalis plant except to remove dead leaves. To decrease the risk of infection, use sterile pruning shears. Remove the unhealthy or dead foliage, and if necessary, cut back the stems to promote healthy growth.
Propagation of Umbilicus horizontalis (Guss.) DC.
Umbilicus horizontalis (Guss.) DC., commonly known as pennywort or navelwort, is a semi-succulent plant native to Europe and Asia. This plant has attractive round leaves and tiny pink flowers that bloom in the summer months. It can be propagated through several methods:
Seed Propagation
Umbilicus horizontalis can be propagated by seed. Collect the fresh seeds from ripe fruit and sow them in a well-drained potting mix. Cover the seeds lightly with soil and keep them moist. Maintain a warm and humid environment for optimal germination. Seedlings will emerge within a few weeks, and once they have several true leaves, they can be transplanted to individual pots.
Division
Umbilicus horizontalis can also be propagated by division. To do this, carefully remove the plant from its pot and loosen the soil around the roots. Gently separate the plant into multiple sections, each with its roots and stem. Replant the divisions in individual pots with fresh soil and keep them well-watered until they become established.
Leaf Cuttings
Umbilicus horizontalis can also be propagated through leaf cuttings. Select a healthy leaf and cut it off at the base. Dip the cut end into rooting hormone and plant it in a well-draining potting mix. Keep the soil moist and provide a warm and humid environment. After a few weeks, the cutting should start to grow roots. Once it has a few leaves, it can be transplanted into its pot.
Overall, Umbilicus horizontalis is an easy plant to propagate. Whether you choose to propagate it by seed, division, or leaf cuttings, you will quickly see the results of your efforts. With proper care and attention, this plant can thrive and add beauty to your indoor or outdoor garden.
