CARING FOR YOUR ROSES - THE ORGANIC WAY
Start with Prevention
Healthy roses begin with the right conditions: ensure they receive at least five hours of sunshine daily and maintain good air circulation around bushes to reduce humidity.
Mulching Matters
Apply mulch to prevent spore splash-back during watering and help retain soil moisture.
Feed Regularly
Consistent feeding strengthens plants, making them more resistant to fungal attacks.
Managing Fungal Issues
-
Moulds and mildews cannot be cured but can be prevented by starting a spraying program early. Use Eco-Fungicide mixed with Pest Oil or Eco-Oil for added effectiveness.
-
For Black Spot, apply Eco-Rose combined with Eco-Oil.
-
Lime Sulphur is a traditional winter clean-up solution (use at double strength) and is effective against Rust, Black Spot, and Mildew. Bordeaux mixtures can also be used in conjunction with these products.
Always follow manufacturer’s instructions for best results.
Spray Equipment Care
Wash out your spray equipment after each use to prevent clogged jets.
Natural Alternatives
-
Milk Spray: Mix one part full-cream milk with nine parts water and spray both sides of foliage every five days or after rain to control mildew.
-
Insect Control: Use Pest Oil or Eco-Oil to suffocate insects or alter leaf surface tension, discouraging egg-laying. These oils also work on Scale.
-
Neem Oil: Can be applied as a systemic spray when used on soil or foliage.
-
Other options include Garlic and Pyrethrum sprays.
