White hydrangeas in pots are a decorative eye-catcher in every garden. Read the following sections about what you need to do to be able to enjoy the sight of them for a long time.
How do I care for white hydrangeas in a pot?
White hydrangeas in pots require a slightly acidic substrate as well as regular water and fertilizer. The pot must have a hole so that excess water can drain freely. In winter the hydrangeas should be placed in a protected place.
What substrate do white hydrangeas need in the pot?
If you plant your hydrangeas in a pot, you can control the soil better than in a bed. It's best to use hydrangea soil, which is optimally tailored to the needs of hydrangeas. If this is not available in your garden center, you can alternatively buy rhododendron soil. This is also suitable because rhododendrons and hydrangeas have almost the same soil requirements. Hydrangeas need slightly acidic soil, which is why the pH value of the soil should be relatively low. Ideally it is 5.5. For this reason, conventional potting soil is less suitable. However, with the right fertilization measures, this can be acidified and used for hydrangeas.
Which pot is best for hydrangeas?
Choose asufficiently large potin which the roots of your hydrangea can develop well. White hydrangeas have shallow roots, so the diameter of the pot is more important than its height. It is important that there is at least one sufficiently large hole in the bottom of the pot through which the irrigation water can drain. Make sure to water regularly so that the substrate does not dry out. Any excess water that collects in the saucer after watering should be poured out immediately to avoid waterlogging. If possible, you can also do without the coaster completely.
How do I overwinter white hydrangeas in a pot?
Since there is a risk in winter that the substrate in the pot could completely freeze, you should overwinter the otherwise hardy hydrangeas in a protected and frost-free place. Even in winter, you should always water the potted hydrangea a little. After the winter, you can take the hydrangea out of its winter quarters and place it in a partially shaded location outdoors.
Tip
Repot hydrangeas in pots regularly
As your hydrangea continues to grow in the pot, you will need to repot it from time to time. This is usually necessary every two to four years. The best time to repot is spring.
