Deficiency of Nutrients And Minerals After Flowering
Once your hydrangea has flowered, it may begin to show signs of nutrient deficiency. The most common symptoms are yellow leaves, stunted growth, and poor flower production.
There are a few possible reasons for this. This can be due to poor soil quality, insufficient fertilization, or incorrect pH levels. First, the plant may not be getting enough of the right nutrients from the soil.
Second, the plant may be suffering from a fungal or bacterial disease that is preventing it from taking up nutrients properly.
Third, insects or other pests may be damaging the roots or leaves, preventing the plant from getting the nutrients it needs.
Finally, extreme weather conditions (drought, heat, cold, etc.) can stress the plant and cause nutrient deficiency.
You may also need to add more fertilizer or compost to the soil. If you suspect that your hydrangea is not getting enough nutrients, the first step is to have your soil tested and adjust the pH levels if necessary. If the problem persists, you may need to consult with a professional to diagnose and treat the underlying issue.
