it has flowered and its flowers have fallen to four seasons. When does it bloom again, when it is repotted or when it is put on the ground?
it often happens that the lemons lose the flowers and the fruits, this event generally depends on where the plant is cultivated; lemons originate from Asia, and have arrived in the Mediterranean area thousands of years ago; in many coastal areas of Italy lemons, and citrus fruits in general, grow outdoors without problems; while in other areas they need some protection during the cold months, because frost and beasse temperatures can ruin the vegetation and flowering. Generally in the nursery the lemons are found in pots, and during the winter months these plants are often grown in unsuitable places, such as at home, or in a temperate greenhouse; in fact lemons can easily live outdoors, provided you do not suffer severe frosts; It is sufficient to cover them with the woven fabric, so that they do not reach excessively low temperatures, and place them in an area sheltered from the wind and well exposed to direct sunlight. I live in Brescia, and my lemon in winter lives in an area south of the house, exposed to the elements; only occasionally I cover it with non-woven fabric, in the coldest weeks of January and February, or in case of intense snow or frost. The first reason for suffering from these plants is generally humidity: positioned at home, or in a temperate greenhouse, lemons live in an excessively hot and definitely too dry climate; to avoid them suffering it is advisable (not having a cold greenhouse or a sheltered terrace) to place them in an area of the house that is not very heated, for example for stairs, as long as they receive direct sunlight. To prevent the air from becoming excessively dry, it is good to vaporize the foliage of plants grown at home; in case of plants growing in greenhouses or outdoors, we check that they receive rain water, because the lemon is not in complete vegetative rest in winter, and without watering it suffers, and could even dry up beyond repair. If you live in an area where lemons can live quietly outdoors, even in the middle of winter, in the middle of the ground, put it to rest in late spring, when the minimum temperatures begin to rise; in placing it as a home, it prepares a hole with a soft and very well drained soil, where no pockets of still water are created and you choose an area with a good quantity of direct sunlight every day. Place the bread on the ground as you find it in the pot, so as to avoid unnecessary stress at the roots. Water every time you find the soil dry; this could mean every day in July, but also only once a week during the autumn months, or even less if the climate is rainy. In autumn and spring, sprinkle a couple of tablespoons of slow release granular fertilizer, specific for citrus fruits, around the stem.
