5. Soil pH Impacts More Than Color
While many gardeners know soil pH affects hydrangea bloom color (acidic soil = blue flowers, alkaline = pink), few realize that extreme pH imbalances can stress the plant.
Aim for a pH between 5.5–6.5 for healthy growth. Use a soil test kit to find out where your soil stands, and amend accordingly with lime (to raise pH) or sulfur (to lower it).
6. Poor Drainage = Root Rot
Hydrangeas don’t tolerate standing water. If your plant sits in a soggy spot, its roots can rot, leading to yellowing, wilting, and eventual dieback.
Revive strategy: If drainage is poor, lift the plant and amend the soil with organic matter, or transplant to a raised bed or slope.
7. Pests and Diseases
Watch for:
Aphids (sticky residue, curled leaves)
Spider mites (webbing, speckled leaves)
Powdery mildew (white coating on leaves)
Fix: Spray with neem oil or insecticidal soap. For fungal problems, prune for better airflow and avoid overhead watering.
Final Tip: Don’t Give Up Too Soon
Hydrangeas are resilient. Even if they look sad now, proper care can bring them back within a season. Focus on watering, placement, and pruning timing, and your hydrangeas will reward you with beautiful blooms year after year.
