A prickly reminder to watch the Wheel Cactus
Posted on 18 July, 2019 by Ivan
What is Wheel Cactus (Opuntia robusta)? A plant native to Mexico, this cactus is most commonly called Wheel Cactus in Australia, and believed to be introduced into our country as a ‘hardy’ garden plant. This cactus species has a distinct blue/green colour and large, flat, round pads with many short and long spines. The pads are circular like a wheel, different to the shape of Prickly Pear. The plant is erect and can grow to 3 metres tall. It has yellow flowers and dark red fruit in spring/summer, each containing approximately 500 seeds which are spread by animals and water. This weed has become widely established in central Victoria, western NSW and south-eastern and eastern SA. It particularly likes to grow on granite outcrops, but also infests woodlands and pastures.
The Tarrangower Cactus Control Group (TCCG) has been battling the prickly problem that is Wheel Cactus (Opuntia robusta) for many years now, ensuring the community and landowners are always on the look out for Wheel Cactus invading the landscape. Three excellent videos from TCCG (see below) have helped the community to easily access the library of information on Wheel Cactus and how to best remove this troublesome plant from the landscape, no matter the level of knowledge.
The three videos cover a variety of topics, such as what Wheel Cactus is and why it is an issue, who the Cactus Warriors are, management options for treating Wheel Cactus and some great footage of the warriors at work. We think the videos are an excellent resource for anyone wanting to know more about managing Wheel Cactus and how devastating it can be on agriculture and the environment alike.
TCCG consists of Landcare volunteers dedicated to the eradication of Wheel Cactus. The group holds friendly and informal community field days to inform and demonstrate control techniques, on the last Sunday of the month from May to October. These field days always end with a free BBQ lunch, cuppa and cake and the opportunity to chat, exchange ideas and make contacts. It is a great opportunity to spend a rewarding morning outdoors, meeting neighbours and others who are concerned about preserving our unique environment. Everyone is welcome, no previous experience is required and all equipment is supplied.
Please contact the TCCG via their website at www.cactuswarriors.org if you have any queries. Click on the videos below to watch each video and learn about the incredible success the TCCG have achieved and how to remove plants correctly.
