The Brazilian guava (Acca sellowiana) is not related to the real guava (Psidium guajava) despite the similarity. Although not externally, the taste of the fruits of both types differ greatly. In terms of cultivation and care, however, both plants are quite similar, with one exception: In contrast to the real guava, the Brazilian guava, also known as pineapple guava or feijoa, is hardy to a certain extent.
The Brazilian guava only tolerates mild winters
Is the Brazilian guava really hardy?
Many traders declare the Brazilian guava as hardy. In fact, the plant tolerates light frosts without any problems, but not permanently and certainly not when the sub-zero temperatures slip into the double-digit range. The shrub comes from the tropics and subtropics and even if there are now quite robust breeds (e.g. from France or New Zealand), they are not fully adapted to the Central European climate with its sometimes harsh winters. So if you have to expect very cold winters in your region, it is better not to plant the Brazilian guava, but to cultivate it in a bucket.
Overwinter the Brazilian guava properly
The shrub is best left outdoors over the summer months. You can move the plant outside from April, but watch out for any late frosts - these can destroy the new shoots. Either put the bucket back into the house overnight or protect the plant with fleece. During the winter months, take care of the Brazilian guava as follows:
- The perfect winter quarters as bright as possible and cool at 10 to a maximum of 15 °C.
- The rule applies: the warmer the winter quarters, the more light the guava needs.
- If the plant is still bearing fruit that has yet to ripen, cultivate it in a warm and bright place.
- In this case, installing additional plant lamps is essential.
- With a cool hibernation, there is no fertilizer and little watering.
How to overwinter the Brazilian guava outdoors
Many a plant lover has even left their Brazilian guava outside during mild winters. In principle, this is possible if you pack the shrub appropriately at lower temperatures and thus protect it against frost. Wrap the pot in warming fleece or bury it in the ground - potted plants are more at risk of freezing due to the lack of a layer of soil. The above-ground parts should also be carefully wrapped with fleece. Be sure to use breathable materials to prevent fungal growth underneath.

The Brazilian guava should be cut back in early spring.
