Sow the seed during autumn. Use a medium which is light and drains well. A mixture of equal parts sand and compost, or just plain coarse river sand, will do. Cover seed with a thin layer of bark or sand and than water. Keep the seed tray in a covered area that provides ample good light and ventilation. Ensure that the medium never gets overwatered nor is allowed to dry out.

Germination takes between 4 - 9 weeks.

Prick out the seedling by the time the first four true leaves appear. Ensure that the fine roots are handled with care. Place the potted plants in a shady area for 3 - 4 weeks to harden them off before placing them in the sun. This period is also a good time to pinch out the growing tips of the seedlings as it promotes more bushy growth habit. The young seedlings can now also be fed with some balanced nutrient products. After 8 to 9 months plants will be ready for transplanting into the garden.

This buchu can also be propagated by taking heel, tip or semi-hardwood cuttings. Use fresh material from the current year's growth. Make cuttings of between 25 - 55 mm, remove about a third of the foliage and cut them below the node. Dip cuttings in a rooting hormone and place them in trays with a medium consisting of equal parts of bark and polystyrene.

If available, place cuttings in a mist unit with heated benches. If you have no special equipment, place cuttings in a protective environment such as under waterproof-sheeting. Keep cuttings damp at all times. This could be done by using a fine sprayer or seal the cuttings of in a plastic bag.

It takes 9 - 11 weeks for roots to develop. The rooted cuttings must be hardened-off (prepared for their final outdoor site) for 2 - 3 weeks. Pot the rooted cuttings into a well-drained mix and then move them to a shady area for 2 - 4 weeks to harden off. After this they can be moved into full sun.

Agathosma serpyllacea performs best in full sun and well-drained soil. The ideal time for planting is between autumn and winter during the rainy season. This allows plants the opportunity to establish themselves in the garden before they have to cope with the harsh heat or drought during summer.

Before planting commences, it is advisable to dig over the soil, add compost and a slow-release fertilizer. This will also aid with aeration of the soil.

Some companion plants for this buchu include: Coleonema album, Elegia tectorum, Delosperma litorale, Lampranthus aureus, L. amoenus, Jordaaniella dubia, Leucospermum patersonii, Pelargonium betulinum, P. capitatum, Lobelia valida, Chrysocoma coma-aurea, Crassula dejecta and Geranium incanum.

Space plants at intervals of 20 - 30 cm which should provide enough space to encourage growth. Buchus prefer a relative dense planting as it helps to retain soil moisture. Plants must be watered well during winter. In summer watering should just be moderate, however do not allow plants to dry out completely. Regular mulching will also assist in keeping the soil and roots cool during summer.
