6. Adjust Flower Color with Soil pH (For Bigleaf Hydrangeas)
One of the coolest tricks with hydrangeas is influencing bloom color by adjusting soil pH (only works with bigleaf varieties):
Acidic soil (pH 5.5 or lower): Blue flowers
Neutral to alkaline soil (pH 6.5 and above): Pink flowers
You can lower soil pH by adding aluminum sulfate or sulfur, and raise it with lime. This way, you can customize your garden’s color palette!
7. Feed Your Hydrangeas During Growing Season
Apply a balanced, slow-release fertilizer in early spring and mid-summer to boost growth and flower production. Avoid over-fertilizing, as it can lead to excessive leafy growth with fewer blooms.
Final Tips
Keep an eye out for pests like aphids and spider mites, and treat early if needed.
Protect your hydrangeas from harsh winter winds by adding a layer of mulch or burlap wrap in colder zones.
Enjoy the beauty! Hydrangeas also make fantastic cut flowers for your home.
With these easy tricks, your hydrangeas will thrive and bloom beautifully season after season. Ready to add some stunning color and charm to your garden? Start planting those hydrangeas today and watch your outdoor space transform!
