Hydrangeas are very robust ornamental shrubs. Cultivation in a pot is possible without any problems, but a few aspects should be taken into account. Find out here when your potted hydrangeas can go outdoors.
When can hydrangeas be placed or planted outdoors?
Potted hydrangeas can be kept outdoors all year round as they are extremely hardy. If you put your hydrangeas in a sheltered, cool place over the winter, they can go back outside after the last frost. If your hydrangea becomes too large for further cultivation in a pot, you can plant it outdoors in spring.
When can I put hydrangeas outdoors in a pot?
If you have moved your hydrangea to a protected place for the winter, such as a winter garden or basement, you canafter the last frost put it back in its original place.
When can I plant hydrangeas outdoors?
If your hydrangeas have becometoo big for their pot, you should repot them or plant them in a bed. You can tell there is a lack of space because the roots are growing out of the drainage holes. Even if your hydrangea looks limp or stops growing, you should give it more space. The best time to transplant is in spring, as soon as the last frost has passed and the soil can be easily worked. Dig a sufficiently large hole, insert the hydrangea and mix in some hydrangea or rhododendron soil.
What should I pay attention to when choosing an outdoor location?
Hydrangeas prefer apartially shaded location in slightly acidic, loose and lime-poor soil. It is ideal if the location is also protected from wind, as this can dry out the plant, especially in strong heat.
Tip
Repot hydrangeas regularly
Every two to four years you should treat your hydrangeas to a larger container. By repotting you ensure that the roots always have enough space and that fresh nutrients are supplied by replacing the substrate. If the pot eventually becomes too big, you should plant the hydrangea outdoors.
