Alum is not necessary for lilac-red hydrangeas. The color of hydrangea flowers is determined by the pH level of the soil. For lilac-red hydrangeas, the soil should be slightly acidic with a pH level of around 5.5 to 6.5. Adding alum to the soil can lower the pH level and help achieve the desired color, but it is not necessary if the soil already has the appropriate pH level. Regularly testing and adjusting the soil pH is the key to achieving the desired color for hydrangeas. **
