Many people fertilize hydrangeas incorrectly—leading to weak blooms or lots of leaves with no flowers. Here’s what you need to know to do it right:
🔍 1. Know Your Hydrangea Type
Different varieties have different needs:
Bigleaf (H. macrophylla): Color depends on soil pH; loves balance (10-10-10).
Panicle (H. paniculata): Tolerates varied soils; may need more phosphorus.
Smooth (H. arborescens): Easy-going, but still benefits from good feeding.
⚗️ 2. Test Your Soil pH
Especially important for bigleaf hydrangeas:
pH 5.5–6.5 → Blue blooms
pH 6.5–7.5 → Pink blooms
Use garden sulfur to lower pH or lime to raise it.
Tip: Test soil every year.
