The favourite diet of roses is a well fed, heavy acidic soil of 5.5 to 6.5pH. If you are not blessed with acidic soils or the leaves are a little pale in colour then a dressing of Sulphur Soil will be ideal in correcting the problem. Our Soft-Water Sulphur will maintain the achieved pH level every time you water your plants, particularly when using hard tap water. Sulphur Rose has been previously known as - Wettable Sulphur - Sprayable Sulphur - Soluble Sulphur.
