Kangaroo paw (Anigozanthos flavidus) is an evergreen plant that's native to the southern regions of western Australia. It produces velvety flowers in a number of colors, including green, red and black. Kangaroo paw typically grows between 16 and 20 inches high, and 24 inches in diameter. Because the plant has adapted to the hot, arid climate of Australia, it can be very difficult to grow in more temperate regions.
Planting
Plant kangaroo paw in a sandy soil mixture to emulate that of its native environment. One part sand to two parts potting soil will provide the necessary drainage. Plant kangaroo paw in a location that receives full sunlight. Keep the soil moist until sprouts emerge (if growing from a seed). Kangaroo paw should never be exposed to temperatures below 41 degrees F, making it almost impossible to grow outdoors. Move outdoor plants indoors before winter, or serious damage may occur.
Watering and Fertilizing
Keep the soil consistently moist during all seasons except winter. Kangaroo paw should be kept dry during winter, when the plant is resting. Only water kangaroo paw with tap water that has been allowed to sit outside for one full day, giving the chlorine a chance to evaporate. Alternatively, fresh rain water can be used, as it has no chlorine content. Kangaroo paw is a fragile plant, and the added chlorine in tap water can cause a decline in health.
Fertilize kangaroo paw with organic compost about once a month. Apply about 1 inch of compost in a small circle around the base of the plant. Avoid fertilizing during winter months, which is the plant’s dormancy period.
Pruning
Regular pruning is required to keep kangaroo paw green and vivacious. Cut off brown and wilted flower stalks at the base of the foliage clump. New growth will replace it in three to four days. Never trim wilted leaves. Trimmed leaves will not grow back, and will remain lifeless until they finally die. Remove the whole leaf from the plant instead of cutting it back only partially, which will allow more sunlight for newer stalks to grow and take their place.
Pests
Snails and ink spot disease are the two most common pests of the kangaroo paw. Snails will eat the foliage of the plant, and can destroy flowers and leaves in days. Leave snail poison around the base of the plant to eliminate or prevent any potential snails.
Ink spot is a fungal disease that causes black spots to form on the leaves. These spots will grow until the entire leaf is black. Remove any infected leaves at the first opportunity, and burn them to kill the fungal spores. Copper-based fungicides can be used in extreme situations to help control the spread, but there is no real cure.
