Wandelröschen are some of the most beautiful flowering shrubs in the garden. But in order for the tropical plant to please the eye with its flower buds year after year, it should get through the winter well. But how should you winter convertible anemones: in a pot at home or outside after all? And do you have to prune them first or is it not necessary to prune them back in the fall? We answer the most common questions about wintering the beauty from the tropics.

How to overwinter convertible anemone? Can the tropical plant stay outside?
Lantanas are common in tropical regions of South America and in some southern parts of North America. There, the Wandelröschen are not hardy and can not tolerate frost and sub-zero temperatures at all. The cultivars that are common in Europe today are mostly hybrid plants. Unlike the wild flowering shrub, they can thrive temperatures down to 5 degrees Celsius. This, of course, means that even these varieties are not hardy in this country. Therefore, wintering outdoors is out of the question. Therefore, if you want to see your lantanas blooming next year, you should dig them up in October, plant them in a pot and overwinter them warmly.
Are lantanas overwintered in light or dark?
A bright, warm room is best for this purpose. A glazed terrace or balcony will allow sufficient light and provide wind protection in winter, but evening temperatures can drop below 0° Celsius. This means that the plant will freeze. Therefore, a heated conservatory or greenhouse is better suited. However, you can also overwinter the winter anemone indoors, in an unheated room. In the apartment or in the house, even in unheated rooms, temperatures rarely fall below 5 degrees Celsius. Therefore, these provide the optimal conditions for overwintering.
Temperatures should be between 5 and 10 degrees Celsius. Too cold and the plant will freeze. Too warm and it will sprout again.
Dark wintering , for example in the garage or basement, is also possible. However, you should make sure that there are no temperature fluctuations. As a rule of thumb, the less light, the cooler you should overwinter the tropical plant. So, if overwintering in the dark, the temperatures should be in the range of 5° to 7° Celsius.
Should you prune the plant before overwintering?
Depending on whether you overwinter the wood anemone in light or dark conditions, pruning may be necessary. If the tropical beauty spends its dormant season in a bright room, then you don’t need to prune it back. However, if it will overwinter in the dark, you should prune it first. Proceed as follows:
- First, cut all shoots in half (about one to two weeks before wintering). A frost-free, warm, but cloudy day is best for this.
- Then dig the plant out of the garden and put it in a pot.
- Then bring the plant to the winter quarters.
However, if the convertible anemone is wintered in a bright place, then you can cut it back only in the spring, around the end of March. In this way, you will encourage growth, the plant will quickly sprout again and form new leaves.
When the wood anemone loses leaves
It is not uncommon for the exotic to lose at least half of its leaves in its winter quarters. If it is overwintered in the dark, it may even shed all its foliage. However, this is no reason to panic. The plant recovers quickly and sprouts vigorously after hibernation.
How often and how much watering in autumn and winter?
Otherwise, convertible anemone is quite easy to care for, even in autumn and winter it does not require special care. The tropical plant is watered as needed. When you bring it to the winter quarters, as well as when repotting, you can do without watering. Wait until the soil dries up. If wintering in bright conditions, water the plant moderately. Too much of a good thing can lead to rot at temperatures above 7° degrees, and that makes the exotic susceptible to pests. The roots could also rot. To prevent this, the pot should have several drainage holes and the soil should be permeable.
If overwintered in the dark, the W andelröschen hardly needs water . Water it very sparingly and really as needed. You should avoid waterlogging in any case.
You can stop fertilizing in October. During the dormant period, the plant does not need fertilizer. Only in the spring, after wintering out, you can provide the exotic with nutrients again to promote new sprouting.
Wintering out takes place in the spring. Then the plant is first brought outdoors for several hours and then during the day and placed in an off-sun place.
