RE: Hydrangea Flowers Have No Color
It could be the breed of the hydrangea. There are berrds that flower green. However most hydrangeas can change color according to the acid of the soil. I have a hydrangea tree. This is the first year it has bloomed. It had white flowers. But I decided to experiment. I put a little vinegar in the water I used to water them. Walla: Beautiful pink hydrangeas.

It has to do with the PH level in the ground. I have a neighbor who adds lime for pink and rhododendrun fertilizer for blue. She says you use 2-3 handfuls and place it a few inches from the roots and scratch it in to the soil. Hope this helps.

Hydrangea colors can be changed by adding white vinegar to the soil for a brighter color but this depends on the acidity of your soil.
Like Beth from MA said, they will eventually fade after being on the bush for the season.
But they make good dried flowers and they are bigger also. I think you have to leave them on the bush or the stem will dry too thin to support the flower part.
Have you tried giving them food coloring in their water? I have never heard of this happening with hydrangeas, but aren't you supposed to be able to to do this with shasta daisies?

I worked briefly for a lawn and garden supply store, and we were taught that the more acid ph the soil, the more blue the hydrangeas will be (also the better for azaleas). So buy an appropriate acidifying fertilizer ( yes, coffee grounds are supposed to be acid ph)
I also recall my very knowledgeable boss informing someone that if their hydrangeas were planted next to a cinder block or cement wall or foundation, that the cement would leach into the surrounding soil and make it a more basic ph - less acidic, resulting in more pinkish or faded looking blooms. So the soil ph would then have to be made more acidic if they wanted blue hydrangea blooms or healthy azaleas. For some reason I have always remebered this. I hope it is useful, and please,anyone who knows otherwise, let me know!

You can change the color by, adding acid. I got this out of the, bhg magazine. It said you do not have to buy colored ones, to get color. It said to add acid type things, to change the color. It has worked for me.

Thanks to all of you. Now I feel like it was not my fault. I also learned that they will not bloom if cut back in fall.

Hydrangea flowers fade after blooming if left on the bush. That's just what happens, no matter how bright they were in the spring. If you want to preserve the blue color, then snip them off at their peak bloom and dry them. Otherwise, they'll fade- which is completely normal.
If you're interested in hydrangeas that continue to keep color after blooming, there are some selections that start out white, then change to mauve as they finish blooming. They stay a pretty dark pink for a long time before eventually fading all the way to brown in the winter. Blues won't do that, though. Sorry!

This won't fix the problem, but it may help in the short run... I have a friend who bought that transparent dried flower spray paint that's made especially for dried flowers for florists. (You can find it at most craft stores) & after her hydrangeas had died & started to loose their color she sprayed the flowers with a med color of blue & a just a hint of purple. She did this by making a mask with a paper plate with a slit & a hole cut in it to avoid spraying the coloring on the leaves. This may sound a bit tacky, but I'll tell you this, she had the most amazing & real looking hydrangeas with wonderful color that lasted well through the fall!
* The trick is to NEVER use spray paint, but actual florist paint.

Hydrangeas I have had for years in all variety of color it depends on how much acid and some root tone you add to it although my mom gets beautiful ones by adding coffee grounds and banana peels and egg shells to hers all the time! she swears by the coffee grounds but buy root tone and jump start it that way first!

Hydrangeas like acid if I remember right. Before I moved I had some Nikko blue and I put coffee grounds to keep them blue, also use the coffee you don't finish and tea grounds as well.

RE: Hydrangea Flowers Have No Color
I am not a real gardener - but I remember somewhere reading about putting rusty iron nails in hydrangea beds to give them more iron & improve color - anyone else here know about that? The color, as I recall has something to do with the ph of the soil?
Editor's Note: My mom used to say the same thing, and would put rusty nails in the soil around hers in the Seattle area.
