Propagation
Surface sow fresh seed from spring to summer in pots and cover them finely with quartz grit, then moisten. Lay piece of glass over the pot and maintain a temperature of 10º to 20º C. (50º to 68º F). Remove glass after germination, and then prick out when large enough to handle and pot up.

Take cuttings during the growing period by removing a piece of the stem and allowing it to lay aside for a few days so the protective skin (callous) can form over the cut.  

Plant up into a well-drained media, where they receive ample light and water sparingly at first.  As roots develop the plant may be watered more regularly, but never allow the soil to be constantly wet.
Use gloves when handling the plant to protect your hands from spines and glochids.

Note
Moderately water during summer, but take care as the plant rots easily in wet soils particularly during winter. 

Botanic information
Leaf: The creamy white woolly areoles have 0-7 radial spines and 1-2 central black spines that are up to 25 mm (1 in) long.

Flower: The bright yellow funnelform diurnal flowers are up to 35 mm (1⅜ in) tall and appear from the top centre of the plant during late summer.

Fruit: The small berry contains large glossy black seeds that have a depression on one side. The seeds are viable but the plant is normally reproduced vegetatively.

General information
Outdoor Cultivation
In warm regions with low humidity, cold and frosty night’s cacti and succulents grow well outdoors. The more humid atmosphere will limit the number of successful species. All of these plants require a very well drained soil and ample sunlight to succeed. Once established these plants require minimal maintenance.

Indoor Cultivation 
Cacti and succulents grow well in glasshouses or near a sunny window with some ventilation tolerating a marked difference in day and night temperatures.
Cacti have a rest period during mid winter when they can be stored in a cooler area with reduced watering, once every two months. Protect the plants from freezing temperatures or extreme direct hot sunlight behind glass. All plants prefer a period outdoors during summer.

Watering
These plants normally have wet and dry periods. Watering should take place during the growing period of the plant. When new growth appears water well once a week and never water if the soil is already wet or place the pot in a saucer of water. Free drainage is essential for a healthy plant and succulents rot easily in moist humid conditions.

Problems related to watering.
Overwatering succulents results in leaves that wilt and discolour or stems that rot.
Under-watering results in a sudden loss of leaves or brown and dry spots on the leaves. Leaves also fall if the water is too cold.

Pots
Both clay and plastic pots are suitable. The pot should fit the plant comfortably and not be too big as it may remain moist, rotting the plant. Water only when the soil has dried.
Re-pot only when necessary in to a slightly larger pot for older plants. If the plants are very large replenish the surface soil and thoroughly water.

Desert cactus that are woolly or spiny use a potting mix of equal parts of sterilised loam, shredded sphagnum peat and gritty washed sand with the addition of one part limestone gravel all chips to assist in strong spine formation. (Never use powdered lime or chalk)
