If you want to learn how to repot hydrangeas to bring them to an ideal location for them, join us in this complete guide.
Hydrangeas are shrubby plants originating in the American and Asian continents, characterized by the spectacular beauty of their white, pink, or blue inflorescences. They are especially popular in Japan, Korea, and China, although they are cultivated as ornamental plants all over the world.
However, hydrangea care can be somewhat demanding in terms of soil, and it is very common to find these plants in poor condition because they do not have the soil they need.

When to Repot Hydrangeas?
Unlike pruning, where you must wait until the plant is in dormancy to minimize the health risk to the plant, repotting will work best when the plant is active and strong.
The best time to repot hydrangeas is in early spring, as the plant has come out of dormancy and has the energy to adjust to its new habitat before the sweltering summer temperatures arrive and put it under further stress.
If the climate in your area is not particularly cold, you can also try repotting your hydrangeas in late winter. This is especially recommended when repotting hydrangeas in poor condition that have been drastically pruned to rejuvenate them. The plant will take longer to adapt to the new environment, but in return, the pruning will be less damaging to it and its root system will not suffer as much.
Tools For Repotting Hydrangeas
Ideally, you should always have tools that are as sharp as possible and properly disinfected before you make any cuttings or cuttings. If you are simply repotting a whole plant, you probably won’t need to prune anything unless some parts are in bad shape.
You will probably need a shovel and gardening gloves if you don’t want to get your hands too dirty, but they don’t need to be protected as these plants have no spikes or harmful substances to irritate.
Next, and also the most important thing, will be to prepare a pot large enough if you are going to put it back in a pot, or the soil area of the garden, and also prepare the soil or soil in which you are going to repot your hydrangea.
Hydrangeas are acidophilic plants, that is, they need acidic soils to develop properly. The pH of the soil in which the hydrangea is placed should be between 5.5 and 6.5, or the plant will eventually experience difficulties in getting its nutrients, and signs of chlorosis will appear.
At this point, it is important to emphasize that although hydrangea flowers can change color depending on the acidity of the soil, they should always be grown in acidic soil, or they will eventually experience health problems.
Thus, get soil for acidophilic plants, or fertilizer that acidifies the soil. It is also possible to use products such as sulfur or iron sulfate, always in measured amounts, to acidify the soil. A more natural way to do this is to mulch with pine bark, which will also achieve great results.
How to Repot Hydrangeas Step by Step
Here are the steps to successfully repot hydrangeas:
1- The first thing to do is to prepare the soil in which we are going to place the plant. Use a mixture with soil for acidophilic plants or previously acidified and, if possible, very rich in organic matter. We recommend this soil for repot hydrangeas (Order it here).
2- Take the cuttings or seedlings that you want to repot. If you have to pull the plants out of the ground, do it very carefully so as not to damage their roots. If they are very crowded because they are old plants, try to loosen them as much as possible with your hands and carefully.
Also, during repotting, make sure that they are in good condition and that the soil is in good condition. If you see or suspect that there is rot, you will have to prune the parts in bad condition and not water the plant for several days, and if you see or think that there is a fungus or other parasites you will have to apply an appropriate treatment (Order it here).
3- Place the plant in its new soil and remember to cover the roots and the base of the stem with soil. It is important to keep in mind that the pot should be larger than the previous one, as well as to place it in the shade for the first few days so that the sun does not stress the plant while it acclimatizes.
4- Maintain humidity in the first days, watering frequently but always without waterlogging, wetting the soil and not the plant.
Care Of Repotted Hydrangeas
A newly repotted hydrangea is especially delicate until it has become accustomed to its new location, so be particularly careful with it. Follow these tips:
- Give it a sheltered, semi-shaded location, protected from direct sunlight but with some natural light.
- Keep the soil moist with frequent watering, but not too abundant so as not to drown the plant. It is always better not to wet the leaves when watering.
- Check the acidity of the soil to make sure it is adequate for your hydrangeas.
- Depending on the amount of lime in the tap water in your area, it may alkalinize the soil too much if you water with it. It is always best to use rainwater or mineral water when watering hydrangeas to prevent this from happening.
