There are many home remedies and hacks for fertilizing hydrangeas, but not all are effective. Coffee grounds, for example, are often touted for their ability to acidify soil, but they should be used sparingly as they can also attract pests.
Eggshells are another popular hack, believed to add calcium to the soil. However, they break down slowly and may not provide immediate benefits. It’s important to research and test any DIY methods before applying them to your garden.
7. The Role of Organic Matter
Incorporating organic matter into your soil can greatly enhance its fertility and structure, providing a more hospitable environment for hydrangeas. Compost, well-rotted manure, and leaf mold are excellent sources of organic matter that can improve soil aeration and water retention.
Adding a 2-3 inch layer of organic mulch around your hydrangeas can also help maintain soil moisture and temperature, while gradually enriching the soil as it breaks down.
