I was told used coffee grounds are good for hydrangeas, roses and azaleas. I would like to know if it is true. Thank you for your help.
Here are links that have great information.
It can be beneficial, and adding your coffee grounds to your compost is also a great idea.

I read the info provided on your site. Thanks, I have a hydrangea (don't now which type) coming up 4 years now and has not produced a single flower. I know it was suppose to be white flowers, but discarded the tag from it. It produces huge leaves and grows and grows, but not a flower to be seen. The leaves are growing on the old wood. I'm getting very frustrated with it and giving this year a last shot and then dumping it. I also have another hydrangea that was a beautiful when in the pot, but since I planted in the garden it hasn't flowered as well. It grows from ground up. On a good note, I do have one that produces nice blue mopheads.
Before you trash it, the soil around the non-blooming hydrangea may be lacking in phosphorus. That can affect the ability of the plant to bloom. Adding some bone meal in the soil should help alleviate the problem in the future. These article will help you learn more (if you haven't already read them):

I am not a great gardener, but I do have fun outside. I have 3 hydrangeas that were given to me. They have not bloomed for the past two summers. What am I doing wrong? HELP!
You are not doing anything wrong. This is a common complaint. You may be lacking phosphorus. If there is a lack of phosphorus in the soil, plants will have little to no blooms. You can either use a phosphorus rich fertilizer or add some bone meal to the soil.

I have a hydrangea that is approximately 8 years old. In the fall of 2013 it was pruned back quite a bit. Before pruning, it bloomed very well every year. For the last 2 years, it has not bloomed at all or maybe just a few blooms. There are a lot of leaves that have a good green color.
Here is an excellent article that will help you.
Determine the type of Hydrangea you have planted.
Also remember weather stresses can and will play a part in the plants performance. We did suffer and very cold winter across much of the United States.

I have a Hydrangea plant from last spring and it has no flowers, just green leaves. Is something wrong or does it take longer to flower through a cool, wet spring?
It is likely lacking a good phosphorus/nitrogen balance in the soil. Too much nitrogen or too little phosphorus will cause it to fail to bloom. This article will have some other suggestions as well:

I have read your advice on non flowering hydrangea. I do not know the type of plant. Should I just let the bush grow as normal this year, then next year do not prune at all to see if this will force flowering?
