These areas are best managed away from larger, more uniform commercial plantings. When choosing a site, try to avoid extreme temperatures and areas with high wind velocity. Be aware of the maximum and minimum temperatures in your locality. Temperatures of 35 C and higher may cause flower buds to drop in some plant species or bracts to turn brown on some Protea s . High temperatures also make crop establishment difficult.
Many species are sensitive to frost.
The critical times for frost are during plant establishment and flower development. Frost may damage or destroy the harvested product on plants such as Protea , waxflower, kangaroo paw, Eucalyptus tetragona and Eucalyptus erythrocorys . Young plants are sensitive to frost and may be killed even though that variety or type is tolerant when mature. If planting in autumn, tree guards may be necessary to protect sensitive species during the colder months. The amount of rain your property receives is important, but so is its distribution throughout the year.
