The traditional way to care for your roses, sulphur is proven to control that old rose problem blackspot.
Sulphur also provides a tonic for improved growth and stronger leaves, which each prevent other diseases, like mildew, from affecting our roses.
Just one of these 250g packs provides enough doses to protect 20 rose bushes for a whole year.
For lasting impact, apply the sulphur monthly from March to October, then every 2-3 months from November to February.
If any hardy rose fails to grow, we will replace it free of charge, you just pay postage.
Our roses are proudly grown right here in England, in our very own rose fields.
We're committed to helping you through every stage of growing roses.
We are proud to have won a Gold Medal at RHS Chelsea Flower Show 2021.
