Opuntia aurantiaca, commonly known as tiger-pear, jointed cactus or jointed prickly-pear, is a species of cactus from South America. The species occurs naturally in Argentina, Paraguay and Uruguay and is considered an invasive species in Africa and Australia.It was declared a Weed of National Significance by the Australian Weeds Committee in April 2012, and was reported by the Committee to be the most troublesome of all cactus species in New South Wales and the worst Opuntia species in Queensland. It is currently controlled biologically in Australia using the cochineal insect Dactylopius austrinus, and to a lesser extent by the larvae of two moths, Cactoblastis cactorum and Tucumania tapiacola.
Tiger pear has strong disease resistance and generally stays healthy under normal care. It can, however, be vulnerable to mealybugs; these pests may cause some harm but are usually not a major problem. Regarding care, Tiger pear is drought tolerant and does not require frequent watering. It can endure extended periods without water and needs little fertilizer. That said, it is highly prone to root rot if kept in poor light and given too much water. Overall, Tiger pear is a good choice for people who prefer low-maintenance plants, though it remains important to meet its basic needs. It is especially suitable for those who are away for long stretches and might forget to water regularly.
How to keep Opuntia Aurantiaca.
Light
Originating from arid regions, the Tiger pear thrives in full sun, since its native habitat has intense sunlight and very little shade. It can also tolerate partial sun, giving it some flexibility in its growth.
Temperature
Tiger pear does best in warm conditions and needs relatively high temperatures during the growing season to foster growth and metabolic activity. It prefers plenty of sunlight, suitable moisture levels, and good air circulation. It is prone to harm from very low temperatures and from too much water. It is also important to maintain balance and avoid temperatures that are too high or conditions that are too dry.
Fertilizer
Tiger pear only needs light fertilizer applied once or twice a year during the growing season. Do not fertilize in winter or summer while it is dormant. Cut back on fertilizer for repotted plants and wait a few months after repotting before feeding. Fertilizing promotes healthy growth and encourages blooms.
