Willow myrtle ( Agonis flexuosa) is regarded as an environmental weed in Victoria and in those parts of Western Australia that are outside its native range. This process is called solarisation and kills remaining spores, When disposing of plants, small plants enclosed in plastic bags can be put in a normal waste bin - NOT the green waste bin. may vary in structure and the cotyledons may be small or large. Agonis flexuosa is naturally found in south-western Western Australia growing in coastal regions and in Jarrah forests from Perth to Albany. Deer also rub their antlers against trees damaging bark and snapping off small branches, this action also incurs damage under hoof as plants, lawns and garden structures are trampled on. The seed must have the appropriate environmental requirements, water, temperature and oxygen. The uniting of vegetative parts with budding and grafting. It grows in an open to exposed sunny position and is drought and frost tolerant. Themigratory Blacktails move southwards during late autumn at the first sigh of snow or heavy sustained rain and the resident Blacktails seek cover their existing territory amongst woodlands during the winter months.
