We can give you advice as to what you should be feeding your roses with and how to prevent them for getting diseases.
Step 1: Roses are big eaters, and after all of this rain it is really important that you keep the food up so that they keep flowering all summer. By feeding your rose with a slow release fertiliser like Neutrog's 'Sudden Impact for Roses', you are going to make it a happier, healthier plant. This will also help your plant build up its natural protections against diseases.
Step 2: During spells of moisture and rain roses become very prone to fungus problems such as black spot and powdery mildew. These diseases can be sprayed for preventative once the rain has stopped to limit the chances of these issues arising. We suggest you use one of these 3 products:
- Sharp Shooters 'Triforine Fungicide' (sold as a Concentrate) which acts as a prevention and control of all of these fungus diseases.
- 'Eco-rose' or 'Eco-fungicide' is an alternative, organic fungicide with the same prevention properties.
- Sharp Shooters 'Rose Black Spot' (sold as a Ready to Use or Concentrate) however, combines Triforine with Pyrethrum to tackle a both fungus and pest related diseases.
- Each product has its own benefits and we suggest asking one of our horticulturists which one will work best for your garden.

Step 3: Natural sources of food such a cow manure and compost will always be appreciated by your roses. Fertilisers will help encourage the plant to grow better, but by adding organic matter you are helping to feed the soil in which your plant is growing and therefore giving it a more long term health benefit.
