However, it can tolerate both high and low temperatures depending on the area where it is being grown. The plant will not do well if it is exposed to extreme cold, drought, and salinity.

Soil Requirements

The Maerua crassifolia Forssk. var. buxifolia (Welw. ex Oliv.) Hiern plant is best suited to growing in well-drained and well-aerated soil. The pH of the soil should be slightly acidic to neutral, ideally between pH 5.5 and 7.5. In order to ensure that the plant has access to all the right nutrients, it is recommended to mix organic matter and fertilizers into the soil before planting. It is important that the soil is moist, but not waterlogged, as excessive water can lead to root rot.

Cultivation Methods

Maerua crassifolia Forssk. var. buxifolia (Welw. ex Oliv.) Hiern is a hardy, drought-resistant plant that grows well in dry and rocky areas. It can be propagated easily from seeds, stem cuttings or layering. The plant prefers a well-drained soil with a pH level of 6.0 to 7.5.

The best time to plant this shrub is in the spring or early summer when the soil is warm. You can prepare the soil by adding some organic matter like compost or manure to it. Once planted, ensure that the plant has access to full sunlight to thrive.

Watering Needs

Maerua crassifolia Forssk. var. buxifolia (Welw. ex Oliv.) Hiern is drought-resistant and does not require a lot of water. Young plants need to be watered frequently for the first few weeks until they establish themselves. Afterward, the plant can survive on natural rainfall, but you can water it once a week during the dry season.

The plant will start to wilt if it lacks water, so keep an eye on it during the dry season. The soil must be well-drained, so avoid overwatering the plant, as this can lead to root rot.

Fertilization

The shrub requires minimal fertilization, and it can grow well without any fertilizers. If you decide to fertilize the plant, apply a light application of a balanced fertilizer during the growing season in the spring or early summer. Avoid over-fertilizing the plant, as this can lead to weak growth or even damage the plant.

Pruning

Maerua crassifolia Forssk. var. buxifolia (Welw. ex Oliv.) Hiern is low maintenance and requires minimal pruning. However, you can prune the plant to shape it and remove any dead or diseased branches. The best time to prune the shrub is after the flowering season in the late summer or early fall.

If the plant becomes too large, you can prune it back severely to rejuvenate it. Heavy pruning can cause the plant to lose its shape and take some time to recover. So, prune it gradually over time.

Propagation of Maerua crassifolia Forssk. var. buxifolia (Welw. ex Oliv.) Hiern

Maerua crassifolia Forssk. var. buxifolia (Welw. ex Oliv.) Hiern can be propagated by both sexual and asexual methods.

Sexual Propagation

The seeds of Maerua crassifolia var. buxifolia can be collected from the plant when they are mature. The seeds should be separated from the fruit and cleaned. The cleaned seeds should be air-dried and stored in a dry and cool place. Seeds can be sown in a mixture of sand, loam, and compost. The pots or beds should be kept moist and protected from direct sunlight.

Asexual Propagation

Asexual propagation can be conducted through stem cuttings. Cuttings should be taken from healthy plants, and the base of the stem should be treated with a rooting hormone. The cuttings should be planted in a mixture of sand and compost and kept moist. The cuttings can be covered with a plastic bag to maintain humidity and increase the success rate of rooting.

In addition, layering can also be used to propagate Maerua crassifolia var. buxifolia. In this method, a low branch of the plant is bent down to the soil, and a cut is made leading to the stem. The wounded part is then covered with soil, and the branch should be fixed in place to prevent it from springing up. When roots have formed, the branch can be cut from the parent plant and transplanted into a new container or garden bed.
