The advantage of hydrangeas kept in tubs or pots is that you can change their location.
You should also take advantage of this.
The ideal spot is sunny or partially shaded and sheltered from the wind.
However, in full sun, such as at midday, or on the bright window sill in the room, the hydrangea quickly becomes too hot.
You can also put the indoor hydrangea on the balcony or terrace and vice versa.
In order to be able to transport the plant easily, so-called plant or tub rollers are useful.
In order to achieve a longer flowering period, it is best to put the hydrangeas in a cooler place like the stairwell overnight.

Potted hydrangeas need a lot of water
In the garden with more root space, the hydrangea has more opportunities to meet its own nutritional needs, but should be kept in the tub with a little help.
These points are therefore also important for hydrangeas in pots:
For hydrangeas, use special rhododendron or azalea soil, which is slightly more acidic than traditional potting soil.
Hydrangeas need a lot of water, but don't like waterlogging.
A drainage layer is particularly useful for this.
It is best to water twice a day with low-lime water, so tap water is usually not suitable.
It is best to water from below as the plant is susceptible to powdery mildew.
From March to August, the hydrangea needs fertilizer every two weeks, hydrangea fertilizer is best.
Remove the faded umbels, but a harder pruning is not necessary.
Potted hydrangeas are more susceptible to diseases and pests such as spider mites, especially if kept as a houseplant in dry air.
Higher humidity, regular watering and a cooler location help here, which in turn promotes flowering.
