    Did you at any time prune them?How old are they?What is your location?

    CUT them back and go buy cheap 2 liter bottles of cola and pour around the plants. Hydrangea s need acidic soil, an the soda should do the trick, and it makes the color of the blooms more vivid.

    Have you fertilized them? To bloom, give a fertilizer high in phosphorus with a low nitrogen content.

    Start in early spring with a 12-8-4 fertilizer SLOW RELEASE. Work into the soil around your plant. This will give you the foliage and it will be healthy and green. You can use this fertilizer every 6 weeks but discontinue after August 1st. After you get healthy foliage, fertilize with a 30-10-10 like Miracid. I use this every 7 to 10 days, with a sprayer to the foliage. You can also sprinkle Epson salts into the ground to turn your soil more acidic. Coffee grounds was mentioned in an earlier post but it takes a long time for the ground to absorb. Also, as mentioned, new growth comes off the wood so don't prune too far down, watch for buds.
    I had 2 plants I had planted in 1995. Every year they grew and had beautiful foliage but they never bloomed. A couple of years ago I learned the above tricks from a master gardener and they have bloomed ever since I started fertilizing correctly. The Epsom salts really helped my plants turn from white, to pink to blue. Good luck, hope this works for you.

      I would use the 12 8 4 fertilizer
      You will usually find it at a nursery
      Use the Epsom salt when the plant starts to bloom. I sprinkle the fertilizer around the drip line of the plant. Same as the epson salt. I would not do together, wait a week or so between

    There was just another question on here about hydrangeas. I found out the hard way that you cannot prune some kinds of hydrangeas. I pruned mine at the end of the summer and got no flowers the following year. I finally learned that some hydrangeas will bloom on old stalks. Google "hydrangeas" like I did to get all the information you need.

    Considering the names of the Hydrangea were not given,fertilizer may not be the answer as sometimes it will produce more leaves then flowers. Key for hydrangeas is not to prune before you can visually distinguish the dead wood that needs o be cut out.
