Hydrangea Flowers Turned Green: Soil pH Fix

New England. Hydrangea had blue flowers; after planting turned green. Moved to sunnier spot, added lime. Will blue return?

Green = pH Transition Zone

Blue requires pH 5.0–5.5 (aluminum available). Pink requires 6.0–6.5. Green = in-between pH. Lime raises pH → pushes toward pink, not blue.

Correct Approach

1. Soil test now (extension service or kit).
2. For blue: Lower pH with elemental sulfur or aluminum sulfate.
3. For pink: Add lime (but you already did).
4. Patience: pH shifts take months.

Don't guess—test. Your nursery can interpret results and sell correct amendment.
