How To Grow Rose 🌹 | Alum Results in Rose Plant 🌿🌹 | How To Make Soil Acidic |

Alum, or aluminum sulfate, is sometimes used in gardening to acidify soil. Applying alum to the soil around rose plants can lower the pH level, making the soil more acidic. Roses generally prefer slightly acidic to neutral soil. However, it's important to use alum carefully and in moderation, as excessive acidity can be harmful to plants. Always follow recommended application rates and monitor the soil pH to avoid potential negative effects on your rose plants.
