The hollyhock, also known as the room maple, is native to Brazil. It is not hardy, but on the contrary needs a lot of warmth in order to thrive and produce many flowers. If it is grown in a pot, it has to move to its winter quarters when the temperatures outside drop too much.

Flowering mallows are not hardy
Flowering mallows are not only not hardy, they only thrive in relatively high temperatures. These should not fall below 18 degrees Celsius during the growth and flowering phase.
If you keep the mallows on the terrace or in a sheltered place in the garden, you always have to keep an eye on the temperatures.
Prepare slowly for winter quarters
- Water less
- No more fertilizing
- Chill for hours
- Check for pests
As summer draws to a close, it's time to prepare the flowered maple for the winter.
Now fertilize less and less until the plant does not get any fertilizer at all. Also reduce the watering so much that the root ball is only moderately moist.
Avoid strong temperature fluctuations
The flowered mallow does not like it at all when the ambient temperatures fluctuate greatly. Before autumn, you should first put the pot in a cooler place for hours and then for days.
This also applies if you take the plant out of its winter quarters again from January. Here, too, the flowering hollyhock should gradually be accustomed to the new environment and the changed temperatures.
Cut back before moving indoors
Since space is usually limited in the winter quarters, you can cut the flower maple harder beforehand. You can reduce them by half. The plant will sprout again in spring.
Check the leaves, especially the undersides of the leaves, for pests before bringing them in. If the flower maple is kept drier during the winter, spider mites, aphids and other pests will proliferate.
It is better to cut off affected shoots generously so that they are not dragged into the house in the first place.
tips
Flowering mallows are quite sensitive in terms of location. They like it warm and sunny, but do not tolerate drafts and cold or heavy rain. If they are cared for outside in summer, they should be covered if possible.
