Admittedly, the constantly required relocation of a plant is quite tedious. Would you prefer to leave your acacia on the terrace all year round? Better not, because the deciduous tree is sensitive to frost. In the following article you will find out how best to overwinter it and what hardy alternatives there are.
The acacia does not tolerate frost well
Are acacias hardy?
Acacias captivate with their southern flair. The deciduous tree is native to Africa, Australia or, more rarely, the United States. There they are used to the warm climate, which is why the only disadvantage of the exotic trees is that they do not tolerate frost. For this reason it is necessary to protect your acacia from sub-zero temperatures.
The acacia overwinter
There are two different location options available for overwintering the acacia:
- a cool, dark place with temperatures of 0-5°C
- or a bright, sunny place with temperatures of 10-15°C
In both cases, the air should not be too dry (no heating air). Ideally, the humidity is at least 50%. Greenhouses (77.12€) and conservatories are ideal for this.
Besides, you should
- keep the root ball moist at all times
- do not apply fertilizer during winter
tips
Keeping buckets makes it easier to change location when the first frost sets in. If you still want to give the impression that your acacia is planted in the ground, dig a hole and put the bucket in it. Then fill the hole with soil. In late autumn you simply dig up the bucket again.
The spherical acacia is the exception
The spherical acacia is a variety with a round growth. Unlike the other acacia varieties, it is winter hardy. However, this property only applies to saplings that are planted in the ground. Cultivated as a container plant, you must also bring the ball acacia indoors in winter to protect it from frost.
