Propagation
Take semi hardwood cuttings during summer or hardwood cuttings with some leaves during winter.
Graft onto C. sasanqua understock. 

Sow fresh seeds in a well drained media but the seedlings may not be true to type.

Note:
Older plants can tolerate a hard prune to rejuvenate.

Botanic information
Leaf: The leathery glossy dark green leaves are broad ovate to elliptical with a prominent mid-rib and have finely serrated margins. The petiole is up to 6mm (¼in) long and the imbricate, green, glabrous conical buds are about 6mm (¼in) long.

Flower: The rotate flowers are solitary or arranged in a small cluster in the upper leaf axils. They may be single or semi-double with prominent yellow stamens and the double forms cover the stamens. The rounded flower buds are imbricate and pubescent, up to 20mm (¾in) long and 15mm (½in) wide. They appear in spring or autumn.

Fruit: The rounded loculicidal woody capsule varies though it usually has a thick wall and may look like a small apple. It contains 1 to 3 brown seeds that produce viable seedlings so the plant is commonly reproduced vegetatively to maintain true to type.

Culture
Soil
Sandy soil should be enriched with the addition of rotted leaf mould or lime free compost. Peatmoss may also be dug in to the soil to add texture.
Clay soils can be improved with the addition of gypsum and course sand. Cultivate well before planting and mulch with leaf mould.

Planting
When planting dig a hole that is twice as big as the container and water the plant thoroughly before removing. Adjust the depth of the hole to match the depth of the pot and firm the soil down. Place the plant in the hole with the pot level and soil level equal. 
Roots that are circling the pot shape may be teased out but be careful not to damage the root ball. Backfill and firm soil down then mulch heavily with composted leaf mould or cow manure. Water in well and stake the plant if required.

Watering
Watering of the plant is dependent on several factors. 
Climate; in a wet area less watering is required and in a drier area watering is carried out more frequently.
Soil type; soils with a poor structure as in a sandy loam require more regular watering than a clay loam.
Budding period of the plant requires a good soaking once a week and if planting occurs during hot weather more frequent watering is required.
Generally speaking the soil should remain moist but not wet and this is helped with adequate surface mulch and monitoring.

Fertilising
As the first sighs of new growth occur during spring fertilising may commence. Use liquid or slow releases fertiliser and ensure that the plant in thoroughly watered before and after fertilising. Do not over fertilise as this will impede the plants development but fertilising may be carried out through summer on a regular basis. Mulches may incorporate milled cow manure; blood and bone mixed with leaf mould or compost. 
Container plants may be feed with liquid or slow release fertiliser once established. It is very important to water regularly and do not allow the pot to dry out, but don't sit the container in a saucer of water as this restricts drainage. Use only quality potting mix and pick a container that is not too large for the plant.

Flower Balling
There are a number of reasons for the buds not opening or falling off. 
It may be that there are too many buds on the tree and manual removal may help or the sun is too strong for that species and protection is required. Some of the older varieties tend to ball easily. Choose the correct variety for the position or improve the culture of the existing plant to overcome this problem.

Pruning
Plants are normally pruned after flowering during spring to summer. Old plants may be pruned during autumn as a form of disbudding. Young plants may be trained to a single leader or tip pruned to bushy up and older plants may be cut back to mature wood. When transplanting mature plants reduce the foliage by 50% and disbud completely.
