Can’t believe I’ve been doing this wrong this entire time

If you wish to change the color of your hydrangea blooms, you can adjust your fertilization practices accordingly. For blue blooms, acidify the soil by adding aluminum sulfate. For pink blooms, increase the soil’s alkalinity with garden lime. Always test your soil pH before making adjustments to avoid over-correction.

Regularly monitor your hydrangeas for signs of nutrient deficiencies or excesses, such as yellowing leaves or stunted growth. Adjust your fertilization practices as needed, and consider conducting a soil test every few years to ensure your plants are receiving the right balance of nutrients. This proactive approach will help you maintain healthy, vibrant hydrangeas.
