This specially blended rose potting mix encourages stronger, healthier blooms from the inside out. The peat-free blend contains 6 months of slow-release feed plus added sulphur and zinc complex to ensure your best ever roses.

Sulphur helps to stave off black spot, while the zinc complex aids production of the plant growth hormone auxin. This in turn improves transport of water and nutrients around the plant, promotes strong root and shoot growth and encourages photosynthesis for energy production.

Supplied in 25 litre bags (please note the contents will settle in transit).
