Cypress Mulch Natural Termite Resistant Product This is 100% Shredded Cypress Bark which is ideal for embankments, slopes and wind swept areas. It retains moisture extremely well, which in turn helps towards reducing water requirements for your garden. The bark has a rich, long lasting natural red/brown colour and complies with Australian standard 4554-2003. It also gives off a lovely fresh cypress fragrance whilst helping control and suppresses weeds. Red Cypress Bark has quite a slow decomposition time, making it last longer.
