Cultivation methods for Ceratonia oreothauma Hillc. & G.P.Lewis & Verdc.
Ceratonia oreothauma, also known as mountain carob, is a tough, evergreen tree that can tolerate a wide range of environmental conditions. It prefers well-drained, sandy soils but can also grow in rocky or clay soils. It requires full sun exposure and can tolerate drought, wind, and salt.
Propagation can be done through seeds or cuttings. Seeds should be soaked in water for 24 hours before planting, while cuttings should be taken from young branches and treated with rooting hormone before planting in well-draining soil.
Watering needs for Ceratonia oreothauma Hillc. & G.P.Lewis & Verdc.
Ceratonia oreothauma is drought-tolerant and only needs to be watered when the soil is dry. Overwatering can lead to root rot and other diseases. During dry spells, the tree may need to be watered twice a week, but in normal conditions, once a week is sufficient.
It's best to water deeply and infrequently, allowing the soil to dry out between watering. The tree should be watered at the base rather than on its leaves and branches.
Fertilization of Ceratonia oreothauma Hillc. & G.P.Lewis & Verdc.
Ceratonia oreothauma does not require regular fertilization but can benefit from a yearly application of a balanced fertilizer in the spring. The fertilizer should be spread evenly around the tree's root zone and watered in well.
Alternatively, organic compost or well-rotted manure can be spread around the tree instead of chemical fertilizers.
Pruning for Ceratonia oreothauma Hillc. & G.P.Lewis & Verdc.
Pruning should be done in the winter when the tree is dormant. Dead, diseased, or damaged branches should be removed, as well as any branches that are crossing or rubbing against each other.
It's best to avoid heavy pruning as Ceratonia oreothauma does not respond well to this. Instead, light pruning should be done to maintain the tree's shape and size.
Removing the lower branches can also help to create a clear trunk, which may be desirable for certain landscaping purposes.
Propagation Methods of Ceratonia oreothauma Hillc. & G.P.Lewis & Verdc.
Ceratonia oreothauma Hillc. & G.P.Lewis & Verdc., commonly known as mountain carob or Mt. Kilimanjaro carob, is a slow-growing evergreen tree that can be propagated through several methods. These include seed propagation, grafting, and air layering.
Seed Propagation
Seed propagation is a common method used for Ceratonia oreothauma Hillc. & G.P.Lewis & Verdc. Seeds are collected from the ripe fruit pods and cleaned. Since the seeds have a hard outer coat, they require scarification, which involves nicking or rubbing the outer coating to facilitate germination. After scarification, the seeds are soaked in water overnight and then sown in a germination mix.
The germination mix should be well-draining, and the ideal temperature for germination is between 20-30°C. Germination can take anywhere from 2-12 weeks. Once the seedlings have developed their second set of leaves, they can be transplanted into individual pots or directly into the ground.
Grafting
Grafting is commonly used to propagate Ceratonia oreothauma Hillc. & G.P.Lewis & Verdc. because it allows for the transfer of desirable traits from one plant to another. The scion (the desired plant) is grafted onto the rootstock of another tree of the same species. Grafting is typically done during the dormant season, and grafts should be kept moist and protected from direct sunlight until they have successfully merged.
Air Layering
Air layering is a propagation method that involves wounding a branch and encouraging the growth of new roots. To air layer Ceratonia oreothauma Hillc. & G.P.Lewis & Verdc., a section of bark is removed from a side branch, exposing the cambium layer. The wound is then covered with moist sphagnum moss and wrapped with plastic film to maintain humidity. Roots should begin to develop within a few months, and once they have, the new plant can be cut from the parent tree and replanted.
