Hydrangeas are not only beautiful plants for the garden, you can also wonderfully cultivate the perennial in a bucket. We show you how to do it.Hydrangea as a container plant
With hydrangeas planted in tubs, you can not only beautify the entrance area, but also the terrace or balcony. But no matter where the diverse plants ultimately find their place: with their large flowers, which are available in many different colors, they will always enchant everyone. Nevertheless, there are a few things to consider when planting hydrangeas in a bucket.
The right location for tub hydrangeas
Hydrangeas like it mild, warm and bright, so the terrace is an ideal place where the plant is well protected. But even if the hydrangea is very heat-loving, you should not put it in the blazing sun, otherwise there is a risk of burns. In addition, the bloom is then not so lush.
The sun in the morning and evening is far from being so intense. The hydrangeas tolerate these quite well. The penumbra is therefore ideal for hydrangeas. They should also be protected from the wind, but it still has to be nice and airy.
There are also non-hardy varieties of hydrangeas. They have to spend the winter indoors. The others can stay outdoors if you place them in a protected place. (Reading tip: hibernate hydrangeas in a bucket - how it's done)
The ideal planting substrate for hydrangeas
If you want to plant a hydrangea in a bucket, you also have to deal with the appropriate substrate. Hydrangeas need a slightly acidic soil that does not contain lime. A special azalea soil from the trade is ideal for filling the bucket, because it fulfills all the needs of hydrangeas.
If you plant a variety with blue flowers, the pH must be between 5 and 5.5. However, you can also plant a pink variety and then add either potassium alum or ammonia alum from the pharmacy via the irrigation water. Then the flowers turn blue.

In order for the hydrangea to flourish well in the planter and for its roots to form without any problems, you have to repot it every two to three years.
Water the tub hydrangeas correctly
As far as hydrangea care is concerned, you should know that hydrangeas need a lot of water (however, waterlogging should never occur). Since the plants cannot tolerate lime, you should not water them with tap water. Rainwater is ideal. If the hydrangea gets too much lime, it shows on yellow leaves. Later the plant even dies completely.
Especially in summer, when the hydrangeas are in bloom, they need a lot of water. At high temperatures, you should even water in the morning and in the evening. You must always keep the soil evenly moist. The hydrangea, on the other hand, does not need as much water during hibernation. Only from February onwards does the water demand increase slowly.
By the way, you should water the plants only in the root area, because if the leaves and flowers become damp, there is a risk of mildew.
