If you're looking for a remedy for black spot on roses, sulphur is a natural enemy of black spot and powdery mildew on roses. It is common knowledge and in the public domain, that these diseases were less common when sulphur dioxide was emitted by coal fires and industrial pollution prior to the 1968 Clean Air Act.

Prevention of black spot on roses is better than a cure! In early spring rose plants should be sprayed thoroughly with Sulphur Rose, once sprayed the fungal spores cannot germinate in the sulphur film (Sulphur Rose) and therefore cannot get a chance to attack the plant. During the flowering season, roses should be sprayed every month if heavy rainfall sulphur rose should be reapplied.

    Can appreciate the effectveness of the use of sulphur on roses, but at £17.50 for treating 20 roses is extremely expensive, taking into account I have over 300 bushes, so need something more economical. Been using Chronos from South Africa. Maybe I'll just stick to my old remedy of skimmed milk and water. I really need a commercial quantity.

    Dear Mr Dowling

    Thank you for the review, Sulphur Rose priced at £17.50 treats 20 roses for the complete year which equates to £0.875 per rose bush. Rose bushes are very expensive so to maintaining them to a high standard a quality product that works is required - would you put a poor quality oil in a Rolls Royce?.

    If you have a large amount of roses i.e 300+ please give us a call and we can supply in bulk - as we do with our rose wholesalers/growers
