I recently moved to a new house, and I've noticed that all the rose bushes have developed black spot disease. I've already removed the worst affected leaves, but I'm looking for a safe, wildlife-friendly solution. Which is more effective for treating this issue: vinegar or baking soda?

Actually, instead of vinegar or baking soda, you might want to look into using sulphur powder. It’s a natural antifungal that's safe for organic gardening and works well against black spots. Vinegar could harm your plants, and baking soda isn't as effective. Here’s a link to a product you might find useful: [Sulphur for Roses](https://www.therosesociety.org.uk/product/sulphur-rose-by-greenacres/).
Oh, that's awesome! Thanks for the tip, I’ll definitely check it out.
