Cultivation Methods for Grubbia Rosmarinifolia
Grubbia rosmarinifolia is a Mediterranean shrub that requires a sunny location. The species has a versatile soil adaptability, withstanding various soil conditions such as alkaline, clay, chalk, loamy, and sandy. Well-drained soil is preferable to avoid excess moisture, which may lead to fungal infections.
Watering Needs for Grubbia Rosmarinifolia
During the growing season, regular watering of the plant is crucial since it is drought-tolerant. However, over-watering the plant may result in root rot disease and various fungal infections. It is crucial to wait until the soil has dried before another watering schedule. Irrigation should be minimal during winter to prevent root damage from cold temperatures.
Fertilization of Grubbia Rosmarinifolia
To promote healthy growth and encourage flowering, Grubbia rosmarinifolia requires adequate feeding. It is best to apply a balanced, slow-release, and organic fertilizer during spring after the first flush of flowers has emerged. Extra feeding of the plant should be done only when necessary since excessive feeding may result in excessive foliage growth, leading to reduced flowering.
Pruning of Grubbia Rosmarinifolia
Grubbia rosmarinifolia requires minimal pruning, but regular deadheading of the flowers is encouraged to promote continuous blooming. The best time to carry out pruning is after the flowering season during autumn. It is important to use sterilized pruning tools to avoid transmitting any infections from infected parts of the plant.

Propagation of Grubbia rosmarinifolia
Grubbia rosmarinifolia, commonly known as rosemary grubbia, is a woody shrub found in South Africa. It is primarily propagated through cuttings. Here are the different methods of propagating Grubbia rosmarinifolia:
Softwood cuttings
Softwood cuttings are taken in late spring or early summer when new growth appears. Cuttings should be about 4-6 inches long and have at least two nodes. Remove the bottom leaves and dip the cut end in rooting hormone before planting in a well-drained potting mix. Keep the soil moist and the cutting in a shaded location. After 6-8 weeks, roots should begin to form, and the cutting can be transplanted to a larger pot or directly in the ground.
Herbaceous stem cuttings
Herbaceous stem cuttings can be taken in late winter or early spring when the plant is still dormant. Cuttings should be about 3-4 inches long and have at least two nodes. Remove the bottom leaves and dip the cut end in rooting hormone before planting in a well-drained potting mix. Keep the soil moist and the cutting in a cool location with bright indirect light. Roots should begin to form after 6-8 weeks, and the cutting can be transplanted to a larger pot or directly in the ground.
Semi-hardwood cuttings
Semi-hardwood cuttings can be taken in late summer or early fall when the plant has finished its growth for the season. Cuttings should be about 4-6 inches long and have at least two nodes. Remove the bottom leaves and dip the cut end in rooting hormone before planting in a well-drained potting mix. Keep the soil moist and the cutting in a shaded location. After 6-8 weeks, roots should begin to form, and the cutting can be transplanted to a larger pot or directly in the ground.
Propagation of Grubbia rosmarinifolia is relatively easy, and once established, the plant is hardy and drought-tolerant.
