A spoonful of baking soda helps roses fight fungus and pests

Baking soda, a common household ingredient, can be a powerful ally in caring for your roses. Its natural properties help combat fungal diseases and deter pests effectively. Here’s how you can use baking soda to keep your roses healthy and thriving:

Materials Needed:

  • Baking soda
  • Water
  • Spray bottle
  • Optional: Horticultural oil or insecticidal soap

Using Baking Soda for Roses:

  1. Prevent Fungal Diseases:
    • Mix 1 tablespoon of baking soda with 1 liter of water in a spray bottle.
    • Add a few drops of horticultural oil or insecticidal soap (optional).
    • Shake well to combine.
  2. Application:
    • Spray the baking soda solution onto the foliage of your roses, covering both sides of the leaves.
    • Focus on areas prone to fungal infections, such as new growth and lower leaves.
  3. Repeat Regularly:
    • Apply the solution every 1-2 weeks, especially during humid or rainy periods.
    • Baking soda creates an alkaline environment on the leaf surface, making it less hospitable for fungal spores.
  4. Control Pests:
    • Baking soda can also deter pests like aphids and spider mites.
    • Spray the solution directly on pests to disrupt their feeding and reproductive cycles.
  5. Monitor Effectiveness:
    • Watch for signs of fungal diseases like powdery mildew and black spot.
    • Check for pest activity and reapply as needed.

Tips for Using Baking Soda:

  • Timing: Apply the solution in the morning or evening to prevent leaf burn from sunlight.
  • Coverage: Ensure thorough coverage of the foliage without excessive dripping.
  • Consistency: Maintain regular application to prevent fungal outbreaks and manage pest populations effectively.


By incorporating baking soda into your rose care routine, you can naturally enhance their resilience against fungal diseases and pests. This simple and cost-effective method offers a gentle yet effective way to maintain healthy roses without resorting to harsh chemicals.
