My 2 Blue Hydrangeas are very healthy looking but have not blossomed and should have by now. They have blossomed since I planted 2-3 years ago but not this year (so far). Why?

I want to move a two year old hydrangea and need to know what the soil needs and best time of the year for moving, and do I trim or cut back before moving?
I would put it off until fall if at all possible, or wait until next spring. However, as long as the plant is properly acclimated beforehand and the temps are not too hot/cold, you can still go ahead and move your hydrangea now. Be sure to place it in a suitable location and give it plenty of water deeply until the plant re-establishes itself. Also, make sure to get up as much of the roots and surrounding soil with it. You may want to prune it back some too so that the plant focuses on root growth rather than foliage/blooms. Here is information on their care: https://www.gardeningknowhow.com/ornamental/shrubs/hydrangea/growing-hydrangeas-hydrangea-care-guide.htm
Five or six years ago neighbor gave us a healthy hydrangea saying it wouldn't bloom for her. In that time we moved it around to give it the best sun, etc. It bloomed one year...that's it. What's wrong?
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.

My hydrangea has tons of buds, but only a few petals open up on each bud cluster. Then they stop. They don't fully open.
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:

Hydrangea petals are fading in color and tips are drying. Plants are in good sun/shade mix and are watered daily. What is the cause and the cure for this condition? This is the first summer this has happened, and typically the petals retain their freshness and deep color well into September. Thank you for your help.
Judging from the symptoms, I would blame underwatering. I know you said that they get watered daily and are in a good mix of sun/shade, but if you are having an unusually hot summer or if the hydrangea is getting more sun than in the past, this can cause problems. Sun amount can change if trees or buildings around the plant get larger or are removed. Even the water needs of the plant can change as it gets larger, which means what may have been enough water a few years ago is just too little now. Try increasing the water.
You may also have a root issue that is preventing the plant from taking up enough water. It may be mild root rot or bugs. Check the roots and make sure they are healthy.
The plant may also be having trouble taking up enough nutrients, so you may want to fertilize as well if you have not done so this year yet. Make sure you water well before you fertilize to keep from burning the roots.
I had a gardener plant three small Hydrangeas (Blue/White blooms) in May. The plants are in partial sun and shade on the side of my home. I water them every morning for 10 minutes (during the sprinkler cycle). Many of the blooms have grown very large which is causing the stems to fall to the ground. What do I do to correct this or is it okay for the stems to be laying on the ground? Also, many of the blooms are turning brownish and seem like they are dying. Is it advisable to cut the blooms off right below the bloom (leaving the the stem bare) or will the blooms just die and fall off?
It is common for the flowers to become heavy and lean or fall.

I have a lot of Hydrangeas in my yard and two of the biggest and oldest ones have no leaves and flowers at the end of the stems. Both of these plants produce flowers on old wood. I didn't prune them last year. I have fed them and they have Bayer pest control in their roots. This is done twice a year. Last year they were both big beautiful plants. Help!
No leaves on the plant is likely an indication of pests or disease.
Treat with Neem Oil as it works as both an insecticide and fungicide.
