Acmadenia macropetala easily adapts to growing in the garden where it requires full sun and well-drained soil. It will benefit from well-prepared soil with compost and a thick layer of mulch. The plants also respond well to slow release fertilizer such as 3:1:5.

Acamdenia macroptelala is a small shrub and best used in border planting or in the front display of any garden. Planted in a pot to decorate any stoep or patio. Buchu plants occur naturally in a mixture of fynbos plants and can be used in the same way. Planted with a combination of ericas, proteas, restios, felicias, phylicas, pelargoniums and other interesting companion plants.

This species requires full sun and planted out in-groups of three or five with enough space to grow. Buchus respond to a fairly dense planting which helps to retain soil moisture. Planting is best done during autumn, winter and spring. To retain soil moisture and keep weeds to a minimum, add a layer of mulch . They require good watering in winter and moderate watering in summer. Do not allow plants to dry out, and once established, they will survive periods of drought.

Acmadenia macropetala can be propagated by sowing seed and by taking cuttings.

The seed capsules develop after flowering, seed are collected from the current year's capsules. Harvest the seed after the first capsules opened Place the capsules and seed in closed paper bag or closed container (not plastic). Store it in a warm and dry place. You can hear the seed expelled from the ripening capsule.

The optimum time for sowing is during autumn. Clean seeds and sow on a prepared medium of sand and compost in equal parts in a seed tray. Cover seeds with a thin layer of bark and water. Place seed trays in a covered area with good light and ventilation. Keep seed trays damp and germination will take place within one to two months. Seedlings are pricked out when four true leaves have developed . Take care not to damage the fine roots. Seedlings are harden-off under shade structure for 3-4 weeks before placed in the sun. The growing tips of seedlings are pinched out to encourage bushy growth. Feed buchus regularly with a balanced nutrient. The yellowing of leaves can be treated with an application of iron chelate . After 8-9 months the plants can be planted out in the garden.

Vegetative propagation (cuttings) is done from August to early October when suitable material is produced after flowering. Cuttings have the advantage of producing a larger flowering plant more rapidly than seedlings. Heel- and semi-hardwood cuttings, 50-70 mm, are taken from the current year's growth.

Prepare cuttings by making a clean cut below the node and remove a third of the foliage . Dip the base of the cuttings in a rooting hormone. Firmly place the cuttings in a medium of 50 % bark and 50 % polystyrene. Ideally these cuttings should now be placed in an well-aerated propagation unit with a bottom heat of 24° C. Ideally, rooting occurs in 9-11 weeks. Carefully pot the rooted cuttings, using a well drained, humus-rich, fynbos potting medium (2 parts leaf mould, 1 part coarse sand). Plants are kept under shade for three weeks to harden off before being placed in the sun. Plants will be ready for planting in 7-8 months.

Young buchu plants are pinched back to encourage bushy growth. Once established do not cultivate the soil around the root area.

Feed regularly with a well-balanced nutrient. Phytophtera cinnamonnii, a soil and water-borne fungus, attacks the roots of most fynbos species. High soil temperatures promote the growth of this fungus, attacking the plant's root system. It prevents the uptake of water causing plants to die. Remove infected plants and use soil mulch to reduce the soil temperature. Disturb the soil as little as possible . Treat plants with a special fungicide prior to planting out. This is a precautionary measure to control the fungus and to protect adjacent plants.
