When (on the East Coast) are hydrangea supposed to bloom? I planted one last year---the leaves are beautiful,

Question

but no flowers.

Answer 1

Very soon. I just planted a hydrangea and it is already in bloom. My neighbor has a really big and really old hydrangea hedge. It has not bloomed yet but it will soon. Be patient and enjoy :)

Answer 2

Depends on the type of Hydrangea you planted.

Smooth Hydrangea - an Annabelle type Hydrangea is setting out blooms now. They're green now and will turn white soon. Typical bloom period June - September.

Bigleaf Hydrangea - Nikko Blue type Hydrangea. Bloom period is July - August, though this plant will bloom sooner in warmer climates.

Panicle Hydrangea - Tardiva, Unique type Hydrangea. Bloom period is mid-July through September, though flowers lose color and persist into winter.

Oak Leaf Hydrangea - Bloom period is late June through July. Flower colors fade but persist on plant. Blooms earlier in warmer climates.

Answer 3

The color change in Hydrangea plants is caused by placing Aluminum Sulphate on the ground under the bush. The Aluminum Sulphate that was there last year has washed away. Go to the Garden Center and purchase a new bag of the stuff in powder form. Sprinkle it under the plant and in a couple of weeks they will be colored again.

Answer 4

Mine are alreday in bloom I live in zone 6.
