Lemons, citrus plant

There is nothing wrong with hibernating citrus in the room or heated conservatory at room temperatures. For example, warm locations on the south window, in front of large windows, on patio doors or in attics under the skylight are suitable locations. The lemon tree of Wolfgang E. gets the winter quarters in the apartment at temperatures of 20 to 22 degrees, but not so good - the plant throws off their leaves. In general, the warmer the location, the brighter it should be. A north window in the kitchen as in Gerti. S. is not bright enough and citrus then like to react with a leaf or flower drop.

In principle, rooted olive trees are more frost-hardened than potted plants. At Susanne B. the olive tree spends the winter and looks great. In contrast, the olive of Julia T. has completely discarded all the old leaves and now it is reissuing. Her tree stands in front of a large balcony door in an unheated room at 17 degrees Celsius.
