Potted lemons have limited nutrient supply due to the lack of pot soil. After years of lack of soil fertility, lemons will weaken year by year, with fewer flowers and fewer fruits. In order to keep the lemon blossom and bear fruit every year, it is necessary to turn over the pot.
The best turning time is half a month before lemon germination. Before turning over the pot, prepare a pot that is one size larger than the original pot, take the lemon out of the pot, and don't break the mud. Cut off the topsoil with a thickness of 1 and 2 cm along the mud mass, cut off the dead roots and rotten roots, cut off the soil with a thickness of 1cm at the bottom of the mud mass, and take out the tiles embedded in the bottom of the original pot.
The drainage holes of the new pool are laid with tiles. First, lay a drainage layer with a thickness of 2 or 3 cm, and then lay a layer of nutrient-rich culture soil with a thickness of 4 or 5 cm, which is mixed with a small amount of calcium superphosphate. Then put the lemon mud balls into the pot, fill the culture soil around the mouth of the pot, slightly compact the pot soil, water the roots, put it in a ventilated and semi-cool place, and put it back in place for daily management after one week.
Extended data
Potted flowers need to be moved indoors in early winter, and the location after entering the room should take into account the characteristics of various flowers. Therefore, we should pay attention to the following aspects:
(1) Flowers that bloom in winter and spring, flowers that like light, warm flowers, such as crab claw orchid, cyclamen, camellia, poinsettia and autumn sowing grass flowers, Milan and jasmine, etc. , should be placed on the window sill or near the window sill in a sunny place.
(2) Evergreen flowers and trees that like sunshine but are resistant to low temperature or flowers that are dormant, such as osmanthus and citrus, can be placed in a cool and light-scattering place.
(3) Flowers that are generally not strict with light requirements, such as potted water lilies and Chinese roses, can be placed in a cool place away from light.
(4) Attention should be paid to indoor ventilation: In order to reduce the occurrence of pests and diseases and help flowers grow healthily, windows should be opened for ventilation at noon on sunny days throughout winter.
(5) Fertilizing and watering: After winter, the temperature continues to drop, the metabolism of flowers is slow, or they enter a dormant state. Generally, besides watering and fertilizing potted flowers according to actual needs, fertilizer and water should also be strictly controlled. If the pot soil is not too dry, don't water it, especially the shade-tolerant flowers, to avoid watering too much and causing rotten roots and fallen leaves.
Water for watering flowers in winter must be dried and reused when the water temperature is close to room temperature. The general watering time should be around noon. For some evergreen flowers, such as asparagus, camellia and so on. They should be sprayed with water close to room temperature frequently to promote photosynthesis.
