This is a common problem that occurs when grown in a protected enclosure (hot house). ) They are appear on both sides of the leaves causing the surrounding area to turn pale yellow then brown and the black spores appear soon after, overwintering on dead infected leaves. Frost and drought mainly occur inland and coastal wind is normally accompanied with rain. The genus name Agonis comes from the Greek agon, "a cluster", referring to the arrangement of the fruits.The species name flexuosa is Latin for "full of bends", referring to the zig-zag course of the stem, which changes direction at each leaf node. Many species may be infected including, species are mildly affected by two types of rust (. ) In order for a seed to germinate it must fulfil three conditions.

As with many Australian plants, phosphorus is toxic to it, as are phosphate-containing fertilizers. Trim the roots as they are dug up and to maintain polarity cut strength at the crown end and a slanted cut at the distal end (away from the crown). The host tree changes to Pseudolarix species during the sexual stage and causes blistering of the leaves. This is a large family of shrubs, mallee and trees with showy stamens and peeling bark. Most fungus is specific to its host and normally will not infect other plant species. Larix species are infected by several Needle Rusts including (Melampsora paradoxa), (Melampsora medusae) and (Melampsoridium betulinum). It certain regions plants infected with this rust must be removed and destroyed to avoid infecting neighbouring agriculture crops. ) The leaves curl and die and the plant becomes stunted. The seed must have no dormancy-inducing physiological, physical or chemical barrier to germination; also the seed must be nondormant.

Root cuttings of small plants are placed in flats in lengths of 20 to 50 mm and laying horizontally on the surface of the soil. The cuttings should be healthy wood with ample supply of stored food as to nourish developing roots and shoots and placed in the rooting media with the aid of a dibbler stick.

They have an inferior to semi-inferior ovary that has 1 to 10 carpels, normally five with 1 to many ovules that are inserted on an axil that is basal or rarely a parietal placenta. The object of the structure is to create an environment where the temperature and humidity can be controlled. Heavy infection can result in the death of soft plant material. The embryo must be alive (a viable seed). Deer resistant plants are the plants that are attached to this file not the susceptible plants. Place a piece of glass over the pot and store in a protected warm environment (glasshouse). Native to south-west WA, the leaves, twigs and gum of the tree were used both ceremonially and medicinally by the Noongar people, to ease congestion, in antiseptic washes and in salves and poultice.
