When planting, ensure you use a well-draining potting mix, with a pH range of 7-8. The plant can grow to a height of 6-10 feet, so prepare a soil bed or pot that can accommodate its growth.
Watering Needs for Maerua campicola Gilg & Gilg-Ben.
Maerua campicola Gilg & Gilg-Ben. prefers low watering. It is important to be cautious when watering the plant, as overwatering can lead to root rot and other moisture-related problems. Allow the top two inches of soil to dry out between watering sessions.
You can also try a period of drought once the plant is well-established, and it can tolerate low moisture levels. But ensure that the soil does not become too dry, as this can also have an adverse effect on the plant and hinder growth.
Fertilizing Maerua campicola Gilg & Gilg-Ben.
To aid growth, regular fertilization would be recommended for Maerua campicola Gilg & Gilg-Ben. Use a balanced, slow-release fertilizer, such as a 10-10-10 mix. Apply the fertilizer at half strength during the plant's growing season.
Over- or under-fertilizing can lead to leggy growth, weak stems, and lower leaf growth, so be careful not to overdo it with the fertilizer.
Pruning Maerua campicola Gilg & Gilg-Ben.
Regular pruning will help maintain the plant's shape and size and promote healthy new growth. Maerua campicola Gilg & Gilg-Ben. needs pruning once a year, preferably in early spring. Cut back the branches to about half their size, and remove any weak or diseased limbs.
Additionally, Maerua campicola Gilg & Gilg-Ben. may produce suckers from the base or sides. Remove these suckers as they appear to maintain the plant's shape and ensure its nutrients go to the central trunk.
Propagation of Maerua campicola Gilg & Gilg-Ben.
Maerua campicola Gilg & Gilg-Ben., commonly known as the knobwood, is a shrub belonging to the Capparaceae family. Propagation of this plant can be done through seeds and vegetative means.
Propagation by seeds
The seeds of Maerua campicola can be collected from the ripe fruit. The pods should be left on the plant until they turn brown and begin to dry out. Once the pods dry, they split open to release the seeds. The seeds should be collected and sown immediately to ensure that at least some germinate. The seeds must be sown at a depth of 2-3 cm in a well-draining potting mix. The pots should be kept moist and placed in a warm, sunny location. Germination can occur in 2-3 weeks.
Propagation by vegetative means
Maerua campicola can also be propagated by vegetative means, including cuttings and layering. The shrub produces some rooting suckers, which can be detached and potted for propagation. Alternatively, cuttings can be taken from the woody stems of the plant. The cuttings should be about 10-15 cm long and dipped in rooting hormone. The cuttings should then be planted in a suitable potting mix and kept moist until they develop roots. Layering can also be used for propagation. A branch should be bent downwards and pegged to the soil. Roots will form at the point where the branch touches the soil. Once the roots have developed, the branch can be cut from the parent plant and potted.
