I'm posting this for a new member who asked me this question b/c I am a member of the welcoming committee.

I received a blue hydrangea plant for Mother's Day and all but one stem have died. It was in a small container so I moved it into a larger one but that didn't seem to help it. I used miracle grow potting soil to replant it. I live in the most southern part of Texas (Harlingen) and I don't know if I'm in the wrong climate to try to grow a hydrangea plant. Currently I have it inside and that one lonely stem is still hanging on. So my question is ( finally ) can it survive in this climate?

Thank you,

It's possible that the plant suffered from lack of water before it was purchased and may take time to recover.
It should be planted in an area of shade with only a bit of morning sun; add water retaining crystals to the soil; keep the plant watered.

If there is still one good stem you could try to cut and root that one in stem vermiculite (Forsyth Pot method) and start fresh.

This is a hydrangea which someone threw away with their yard waste; it was just a dead-looking root ball when I planted it the last week of March 2014. It gets only morning sun in this location.

Here are the first 4 cuttings which I rooted in vermiculite and potted up just yesterday.
My goal is to use the stems from the mother plant and continue to propagate new plants from it.
