Oval tree without damage overwinter - so it works

When hibernating orange trees, as with all citrus plants, the principle is: the warmer the plants are, the more light they need. The flowering of oranges is usually very weak during warm wintering.

Optimal hibernation temperatures for oranges

Oranges should best be overwintered at temperatures of around 5 ° C at night and up to 15 ° C a day. This corresponds to their existing climate conditions at the natural site. On sunny days, the temperature can rise to over 20 ° C even in winter. It just should not become permanent temperature, because then the plants would wake up from their hibernation.

The warmer the lighter

In addition, the available light is the second most important factor: Basically, the warmer, the brighter. From this it can be seen, why overwintered plants in the living room often react with leaves in spring or in some cases even with dying. Your energy reserves from the summer season are slowly used up in the spring, because the light intensity in the living room is not sufficient for photosynthesis.

Duration of light is insufficient in winter

In living-room integrated conservatories and bright living rooms is often ignored that the human eye is much better used to reduced lighting conditions than an orange leaf. No more than eight hours of daylight, filtered through a glazing, seem like a permanent night to the plants. However, since orange trees are evergreen, they need a certain amount of light even in cold wintering in order to maintain their vital functions.

Hibernation in the greenhouse or conservatory

For the reasons mentioned, it is not recommended to hibernate in the heated living room. Hothouse and winter garden, which are kept frost-free in the winter by means of a thermostat heating, are due to their light offer ideal wintering locations. On sunny winter days, however, you must make sure that regular ventilation avoids temperatures above 12 ° C.

Tips & Tricks

In winter, you should not fertilize your orange tree, pour only a little, and choose a bright, cool and almost frost-free location. Before pests, check for pests and fight them immediately. Cut the plants into shape, harvest the ripe fruits and remove unripe new shoots. Immature fruits can remain on the tree. They just continue to ripen next year.
