Will vinegar kill hydrangeas?

What is the best fertilizer for hydrangeas?

Fertilizing: Hydrangeas do especially well when fertilizers are effectively used in spring or early summer. We recommend using a granular, slow-release fertilizer with a high percentage of phosphorus (the middle number in the NPK ratio). Phosphorus is the element that encourages bloom production.

Do Hydrangeas like sun?

Most hydrangeas thrive in rich, porous, somewhat moist soils. Add compost to enrich poor soil. They prefer full sun in the morning, with some afternoon shade; however, many will grow and bloom in partial shade.

Amend the soil with organic matter (such as compost).

Prune stems back in early spring, just before new growth emerges.

Why is my hydrangea pink instead of blue?

Strongly acid soil of 6.5 or below produces blue flowers; alkaline soil produces pink or red flowers; and near-neutral soil of pH 6.5 to 7 gives you purple flowers or a mixture of blue blooms and pink ones.

If the soil is compacted, mix elemental sulfur or iron sulfate into it to make it more acidic.

Why are hydrangeas different colors?

Changing Hydrangea Colors You see, for most French hydrangeas (Hydrangea macrophylla), the flower color indicates the pH of the soil. In strongly acid soil (pH below 6), flowers turn blue. In alkaline soil (pH above 7), flowers turn pink or even red.
