Lemon juice is an effective way to adjust the pH of soil for optimal growth of hydrangeas. Lemon juice is acidic and helps decrease the alkalinity, allowing for more availability of iron, manganese, and zinc. These minerals are vital for healthy blooms and foliage.
Adding a few tablespoons of lemon juice per gallon of water can create an acidic solution to water your hydrangeas—ideally 2-3 times per week during hot summer months and every few weeks in colder climates. This helps keep their acidity levels in check so they can absorb critical nutrients properly—from Phosphorus to Potassium!
Lemon juice is also a great source of vitamin C and antioxidants that promote stronger stems while preventing the risk of wilt or stem rot. Additionally, the regular application will help block fungal infections and powdery mildews that have been known to plague hydrangeas!
To make sure you’re giving your plants everything they need, mix up a simple solution with 1/4 cup of lemon juice in four cups of lukewarm water. Use this liquid around your plant once every two weeks for maximum benefit. You’ll be rewarded with brighter blooms and more vibrant foliage!
