To grow bigger, healthier hydrangeas using a simple kitchen waste hack, consider using coffee grounds. This eco-friendly method not only enriches the soil but also enhances the blooms of your hydrangeas. Here’s how to do it:
Benefits of Coffee Grounds Nutrient-Rich: Coffee grounds are high in nitrogen, which is essential for healthy foliage and promotes photosynthesis, leading to larger blooms.
Soil Improvement: They improve soil structure and drainage, promoting root health.
Acidity: The slightly acidic nature of coffee grounds can help adjust soil pH, which is particularly beneficial for hydrangeas, especially if you want to achieve blue blooms.
How to Use Coffee Grounds Collect Grounds: Save your used coffee grounds or ask local cafes for their leftovers. Dry the Grounds: Spread the grounds on a baking tray and let them air dry for a day or two to prevent mold.
Application: Sprinkle about one cup of dried coffee grounds around the base of each hydrangea plant once a month during the summer.
Liquid Fertilizer Option: For a liquid feed, soak one cup of used coffee grounds in five gallons of water for a week, stirring occasionally, and use this nutrient-rich solution to water your hydrangeas.
