Cut Flowers- Protea

Proteas are one of the most beautiful flowering shrubs in the world. Originating in South Africa the Protea is also related to Australian plants such as the Waratah , the Banksia and the Grevillea. Many growers include Leucadendrons and Leucospermums under the umbrella of the name "Protea".

Proteas usually flower in their second or third years and have proven to be very adaptable to the Australian climate, they are also reported to grow well in the southern states of the United States. They can vary in size from small shrubs to small trees, the flower size being anything from about 5cm (2") (Protea scolymocephala) to about 30cm (12") (Protea cynaroides, commonly known as the King Protea).

In order to grow a healthy, high yield, flowering Protea shrub it is essential to follow some basic ground rules.

• The soil must be well drained, and if planting in heavy clay soil it is recommended that you build a raised bed, about 60cm (24") high, filled with sandy soil.
• Acid soil is essential.
• Proteas prefer lots of sun and good air circulation so planting away from where trees and buildings are going to block sun for more than a few hours a day is well advised.
• Tiny surface roots develop on the Protea plant and can easily be damaged by cultivation. Laying down mulch, away from the stem of the plant, to prevent rot, is good practice as it reduces weed growth and keeps the roots cool in summer. Always make sure the area around the plant is weed free, but avoid pulling or digging out weeds. Rather, use a spray (carefully), weeding stick or simply cut off weeds at ground level.
• Proteas do not like normal gardens fertilisers. They require very little nutrients and can only cope with a small amount of phospherous. Hoof and horn or well composted manure can be used but is not normally required.
• Proteas must be watered regularly during winter. They prefer drier conditions during summer, once established, but require some watering during long dry spells. Exceptions to this rule are Protea cynaroides and Protea compacta which require regular watering throughout the year. Foliage should not be made wet during hot or humid conditions as this can lead to fungal problems.
• Young Protea plants may need protection from frost. Older plants are quite frost hardy, nevertheless, their yield of flowers can be markedly reduced by severe frost.

The above conditions are good for the majority of Protea species, however there are some exceptions that prefer damper or more lime positions. For more information on these plants or any other enquiries please contact us.
