Once planted, hydrangeas should remain in place. If you still have to replant them, there are a few things to consider.

However, you should never transplant a hydrangea just like that. There are a few important points (such as choosing the right location or the right time for the move) that you should pay attention to.
Time for transplanting & choosing the right location
» Time:
First of all, it is a matter of finding the ideal time for moving the hydrangea. As with most plants, autumn is the best time to plant the hydrangea. Although this is basically also possible in the other seasons, transplanting is associated with the lowest risks in autumn, because then the hydrangea is no longer in full bloom. On the contrary: by autumn the flowers have long since withered, so you can cut them back straight away.
Tip: If it is absolutely necessary to move in the spring, this must be done before the budding begins.
» Location:
The new location should be in partial shade if possible. Slightly acidic soil that is rich in humus and nutrients but free of lime is ideal. Ideally, the soil conditions at the old and new location should be about the same, as this makes it easier for the plant to grow. In addition, the site should be well protected, especially with regard to wintering in freezing temperatures. Incidentally, this also applies if you want to propagate your hydrangeas.
How to transplant hydrangeas
Step 1: dig up hydrangea and dig planting hole
Hydrangeas form very deep roots with many fine root fibers. If you dig up the plant, you must do so as generously as possible. Only with a large hole can you also ensure that you get the entire root ball out of the ground.
You will of course have to dig the planting hole at the future location accordingly. The plant must also be able to spread its roots in all directions in the new location.
Step 2: Transport hydrangea
Older hydrangeas are often so large and sprawling that you will need a second person to transport them. You can also place the hydrangea on a large foil after digging it up and pull it to the new location. You should wrap the root ball in foil anyway after digging it up so that as much soil as possible sticks to it.
Step 3: Plant hydrangea at the new location
Since the hydrangea needs a lot of water, it is advisable to fill the new planting hole with water first. Only then should you put the hydrangea in and fill the hole back up with soil. Even then, proper watering is necessary.
Step 4: water the hydrangea
In the coming days and weeks you will also have to think about sufficient watering, because this is the only way for the hydrangea to grow well.
