Hydrangeas are a feast for the eyes of every garden and they are easy to care for! What is there to do is reveal these 4 tips.
Hardly any other plant in Germany can be admired as often as the hydrangea. That's no wonder: hydrangeas are impressive with flowers in attractive colors and are comparatively easy to care for. If you are looking for a suitable embellishment for your garden, I highly recommend hydrangeas.
But apart from that, you can also do something very special with the hydrangea: you can influence the flower color in a targeted way. Before I get to the care tips, here's some information about biodiversity.
Which hydrangea species are there?
Like all other plants, hydrangeas have a huge biodiversity. In principle one differentiates between:
- ball hydrangeas
- hydrangea macrophylla
- Teller hydrangeas
- Oak leaf hydrangea
It is the growth habit, the many different colors, as well as the shape of the flowers, which make up the differences between the individual species.
Since each of them has their own needs, you should pay close attention to what to pay attention to when planting. For example, the soil and the location have to meet special requirements, with most hydrangeas feeling most comfortable in partially shaded to shady places.
Tips for the care of hydrangeas
As already mentioned, hydrangeas are quite easy to care for, but without it is not possible. What you have to do when depends mainly on the variety.
Tip 1 - Water hydrangeas properly
The most important thing in the care of hydrangeas is irrigation. Especially in dry and very warm weather, the soil must be kept moist (pour in the morning and evening). Once the hydrangeas have dried up, it's over with the beauty.
- When casting, however, make sure that no waterlogging forms, because on the other hand, the hydrangeas are quite sensitive.
- This tip is also valid for hydrangeas in the pot, stagnant water on the ground is to be avoided!
- When you water the hydrangeas, be careful not to spray blossoms and leaves - mildew danger!
- The irrigation water for hydrangeas should not be calcareous, it is best to take rainwater, which also saves money.
Tip 2 - When and how should I fertilize?
Hydrangeas need fertilizers because they are no exception to other plants. But even here it depends on the variety, because not every hydrangea needs the same care. When buying, look for a nitrogen-rich and low-phosphorus product. There are already special fertilizers for hydrangeas, azalea or rhododendron fertilizer is also available (both available at Amazon for less than 10 euros). I advise against blue grain fertilizers.
Potted plants are best fertilized with liquid fertilizer from March to August. For planted specimens and tub hydrangeas, I recommend long-term fertilizer in solid form. Fertilization takes place in spring and early summer.
Tip 3 - Pruning: Does it have to be?
Hydrangeas need no pruning, but if the plants are too big, he has to reach for the scissors. But beware, if you cut off too much you risk that the hydrangea will not bloom again. Almost all varieties are cut in the spring. The exact time you recognize that the hydrangea drives out and first buds are seen. More in the video:

Tip 4 - Hibernate Hydrangeas: That's how it works!
Not all hydrangea varieties are hardy (pay attention when buying). This means that they need to be protected from frost, for example with garden fleece or brushwood. Those who have the space, take in the hydrangeas and winter them at 5 - 8° C. From about February, the hydrangeas are allowed to move to a warmer place, so they can drive out slowly. Potted plants survive the winter only in a sufficiently large vessel. The pot should have a good 30 to 40 cm diameter. Here are some examples of hardy hydrangeas:
|Hardy varieties: farmer's hydrangea||Hardy varieties: plate hydrangea|
|You & Me Hydrangea||Blue bird|
|Bouget rose||Lanarth White|
With good care a dream: color change of the flowers
With the already pretty plants we can observe with the necessary knowledge an impressive special feature: Depending on the nature of the soil, hydrangeas change the color of their flowers. Decisive for the color is the pH of the soil. For example, the flowers bloom blue on acid soil while they are pink on neutral soil.
Just try it yourself and influence the color of your hydrangeas. All you have to do is change the pH of the soil using aluminum sulphate.Add 2 tablespoons of the aluminum sulphate to the water and then marvel at what happens.
Once the hydrangeas in your garden grow and thrive and you really like the color of the plants, you can multiply them later. How it works is explained in our article: Hydrangea proliferation.
