Agathosma mucronulata does best when planted in full sun and needs adequate water during the hot summer months. It requires a soil that is well drained, and enriched with well-rotted compost (leaf mould) and a well-balanced slow-release fertilizer (3:2:1). It is slow growing and needs space in the garden bed to allow it to develop to its full potential, without being squashed by other faster growing plants.

Planting buchus into the garden is best done after the first good winter rains have fallen (May to July). Buchus respond well to fairly dense plantings, so plant a number of the same species fairly close together e.g. in groups of three of five, and in this way you will get a more dense and floriferous bush and help to retain soil moisture. A good thick mulching of well-rotted compost applied once a year will reduce weed growth, keep the soil temperature even, and conserve moisture during the hot dry summer.

Buchus occur naturally in mixed fynbos and are ideally suited to the fynbos garden, grown with other fynbos plants such as proteas, ericas, restios, pelargoniums, vygies, helichrysums, phylicas and felicias. Agathosma mucronulata also makes an attractive border plant, it is a useful filler plant, and it can be used in the rockery. To enjoy the scented foliage, plant it beside a path or in a container on a patio, where it will release its fragrance whenever it is touched. Other species suitable for the garden include Agathosma lanceolata and Agathosma ovata 'Kluitjieskraal'.

Buchus can be grown from seed or cuttings. Fresh buchu seed should be sown in autumn (April). The seed is sown into a tray containing a well-drained medium of equal portions of sand, loam and compost. Use some of the medium to cover the seed, and water. Place in a covered area with good light and free air circulation and keep damp. Germination occurs in 1 to 2 months. When the first four true leaves have developed, the young seedlings are pricked out into 0.5 litre bags containing a well-drained, humus-enriched potting medium (e.g. 2 parts leaf mould : 1 part coarse sand). Feed regularly but sparingly with a well-balanced fertilizer. Pinch out the growing tips of the seedlings to encourage bushy growth. Flowers are produced after two years.

Cuttings have the advantage of producing a larger plant that will reach flowering size sooner than seedlings. Tip cuttings, 50-70 mm, are taken from the current season's growth in spring (September to November). Prepare the cuttings by making a clean cut below the node and remove a third of the foliage. Dip the base of the cutting in a rooting hormone such as Seradix 2. Plant the cuttings firmly in a medium of 50% bark and 50% polystyrene. Ideally these cuttings should now be placed in a well-aerated propagation unit with bottom heat of 24° C and intermittent mist. Rooting occurs in 9 to 11 weeks and a weaning period of 2 weeks is recommended. Carefully pot the rooted cuttings into a well-drained, humus-enriched potting medium (e.g. 2 parts leaf mould : 1 part coarse sand). Feed regularly but sparingly with a well-balanced fertilizer. Yellow leaves can be treated with an application of iron chelate. Plants will be ready for planting in 7 to 8 months.
