Question: lemon without leaves
Good evening, I've had a lemon for several years. usually in the winter I put it in a greenhouse on the balcony but for reasons of space this year I had to bring it home. It is in a living room with about 17 18 degrees and low light. for some days it has started to lose all the leaves and only the lemons are left (15circa). in the greenhouse had never happened. could you tell me what I could do to help the lemon recover? do lemons have to be removed? thanks
Answer: lemon without leaves
lemons are evergreen plants originating in Asia, in areas with a subtropical climate, characterized by good humidity and minimum temperatures almost always above 10 ° C. In Italy, lemons are grown only in coastal areas, where the presence of the sea, especially in winter, makes temperatures mild; or in the southern areas, especially in Sicily and Puglia, where the winter lows are definitely different from those we can find in Lombardy (just to give an example). For this reason, if we want to grow a lemon, but we live in an area of Italy with minimum temperatures below zero, it is necessary to keep the plant in a sheltered place; lemons can withstand temperatures of a few degrees below zero, but only for short periods, and obviously if they are in full bloom or with fruits (as typically occurs in winter), it will be necessary to cover the plant or repair it from the cold, to avoid losing it all the harvest. So, usually, it is sufficient to cover the plant with non-woven fabric, and keep it in an area of the garden facing south or south east, possibly with the protection of the house, as can happen on a terrace. If it is not possible to find a position of this type, it is not absolutely advisable to move the plant in the house; rather it is better to cover it with a small greenhouse, or with more layers of non-woven fabric. This is because at home the temperatures are too high, and in the correct evolution of the seasons it is right that a lemon should bear a few weeks of cold or cool climate. In addition to this, and more importantly, the climate in the home is excessively dry: domestic heating, any stoves or fireplaces, tend to dry the air very much, making it very different from the one we find outdoors. Living an entire winter in the home therefore brings the lemons to great suffering; the first thing to do, as you rightly suggest, is to remove the fruits, to avoid the plant spending all its energies on growing them. Then you can think of vaporizing the leaves frequently, with water at room temperature, also trying to move the plant in a well-lit area of the house. Unfortunately it is now impossible to immediately move the plant outdoors, as the nocturnal climate is still much colder than the one found in the house; unfortunately you will have to wait a few more weeks, hoping that in the meantime the plant does not suffer excessively.
