To cultivate this plant, you will need to prepare a well-drained garden bed with sandy loam soil. The soil should have a pH of between 6.0 and 7.5 for the best results.
Plant the seeds directly in the garden bed during the spring or summer. Sow the seeds 1/4 inch deep and keep them moist. Germination should begin within one to two weeks, and the seedlings should reach maturity within three months. You can also propagate the narrow-leaved gumweed using stem cuttings or by division.
Watering needs for Leucas stricta Baker
Leucas stricta Baker requires moderate watering during its growing season. Water the plant once a week or whenever the soil feels dry to the touch. The plant is drought-tolerant and can withstand periods of dry soil without sustaining significant damage. Overwatering, especially during the winter, can cause root rot and fungal diseases that can be fatal.
Fertilization of Leucas stricta Baker

You can feed it with a balanced fertilizer once a month during the growing season to promote healthy growth and blooming. Alternatively, you can add a layer of organic compost to the soil around the plant in the spring to provide the necessary nutrients.
Pruning Leucas stricta Baker
Leucas stricta Baker does not require heavy pruning except to remove any dead or damaged branches. Prune the plant in early spring before the growing season begins. Pinch back the tips of the stems to promote bushier growth and a more compact shape.
Propagation of Leucas stricta Baker
Leucas stricta Baker, commonly known as narrowleaf black snakeroot, is a herbaceous plant species that belongs to the Lamiaceae family. It is native to Africa and is widely distributed in countries such as Ethiopia, Somalia, Kenya, Tanzania, Zambia, and Zimbabwe. Propagation of this plant can be done through different methods such as seeds, cuttings, and division.
Propagation through Seeds
The seeds of Leucas stricta Baker can be collected from the mature plant and sown in the nursery beds during the spring season. The soil must be moist and fertile. The seeds should be sown at a depth of 3-5 cm and covered with a thin layer of soil. Water the soil regularly to keep it moist. The seeds will germinate within 2-3 weeks, and the seedlings can be transplanted to the main field when they are 4-6 weeks old.
Propagation through Cuttings
The stem cuttings of Leucas stricta Baker can be taken from the parent plant during the early summer season. Cuttings should be about 10 cm long and should have at least 2-3 nodes. Remove the lower leaves and plant the cuttings in the nursery beds filled with moist sand or vermiculite. The cuttings should be kept in a shaded area and watered regularly. The cuttings will root within 4-6 weeks, and the rooted cuttings can be transplanted to the main field.
Propagation through Division
The mature plants of Leucas stricta Baker can be divided during the early spring season. The clumps should be lifted carefully, and the roots should be washed to remove the soil. Divide the clump into several smaller clumps, ensuring that each has sufficient roots and shoots. Replant the divided clumps in the nursery beds or the main field, depending on the growth stage of the plant.
Disease and Pest Management for Leucas stricta Baker
