In extreme cases the whole plant may die. As four different fungi seem to be responsible, no single fungicide gives effective control. Cultivation in an open sunny position and avoidance of overhead watering may reduce the severity of the disease. Manipulated hybrids of Red and Green Kangaroo Paw and the less spectacular A. flavidus have been produced. The most horticulturally desirable one shows superior foliage quality and increased resistance to snail damage and fungal disease, while retaining the spectacular flower colours of Mangles' Kangaroo Paw.
Tissue culture enables the production of large numbers of particular colour forms.
Fresh flowers of Red and Green Kangaroo Paw last well in water and its brilliant colours and unusual form are exploited to great effect in simple line arrangements. It retains its colours well as a dried flower and is often sold in bunches of mixed Western Australian wildflowers. Considerable impact occured on wild populations of this species by the collection of flowers to provide both fresh and dried material for local use and export, but supply is largely now from cultivated plants.
