Potted lemons love yellow leaves. What steps can't be done well, not only yellow leaves, but also fruit loss? Nowadays, many people like to grow lemons in flowerpots at home, because lemons belong to fruit trees, and what people usually see are relatively large plants. In fact, lemon seedlings only need to grow within 2 years. After the plants grow to a certain size, they can bear fruit in flowerpots. Potted lemons are very popular now, and many flower lovers like to plant a pot at home. If the seedlings are too big, it is no problem to pick dozens of fruits. So how should everyone cultivate lemons at home? What should I do if lemons often turn yellow? What caused it?

Because everyone can't keep up with the fertilizer and water, because lemons want to bear fruit, they are planted in flowerpots, which have a small soil layer and need to be watered and fertilized. If it is habitually short of water, its leaves will be rolled up and can be repaired after watering, but if it is short of water once or twice, the leaves below it will turn yellow and fall off in a large area after many times. Don't lack water, and be sure to raise lemons.

Fertilizer also needs to be given to him regularly and quantitatively, because lemons can't grow and develop without fertilizer. If it is not fertilized for a long time, its bottom leaves will turn yellow and fall off in a large area. Lemons in the growing period should be filled with multiple fertilizers as much as possible, and when they sprout and bloom, they will bear fruit. Everyone chooses a fertilizer with high phosphorus and high potassium, such as No.2 with many flowers, so that it can blossom and bear fruit if it is used regularly and quantitatively to ensure sufficient nutrients. When the fruit is ripe, it can be irrigated with a high-potassium fertilizer, which will make the fruit grow rapidly and improve rapidly, and it is not easy to drop fruit.

The primary reason why lemon leaves fall is that the potted soil is alkaline. Lemons belong to southern plants. Large-scale planting can be carried out in the south, and potted plants can be planted in the field. But in the north, the water quality in the north is alkaline and the soil layer is alkaline, which is not suitable for him. After a long time, the soil layer is alkaline and can't digest and absorb iron, and the newly grown leaves of lemon will turn yellow widely. Therefore, when people in the north raise lemons, we must remember that the aqueous solution of ferrous sulfate or chelated iron should be irrigated regularly, once a month or two, to keep the acidity of the soil layer and not lack of iron, so that the new buds are not easy to yellow.

Because the temperature is too low, lemon has been mentioned. This belongs to potted flowers in the south. Southern potted flowers are afraid of ultra-low temperature. If we raise them in the north, if the indoor temperature is below 5 degrees in winter, their leaves will fall off in a large area, and if it is below 0 degrees, they will freeze to death or even freeze to death. Everyone should try to ensure that the ambient temperature is above 10 degrees, which will lead to hibernation, which is higher than 15.

Lemons are very easy to grow. Belonging to woody plants, the root system is relatively developed. Everyone should use a soil layer with good air permeability to cultivate it. Try not to cultivate in deep pots. Use a short pot and water it well at ordinary times. Potted soil needs to be placed in a sunny place all year round, and then different fertilizers are selected to fill it according to its growth and development season and fruiting season in order to grow and develop normally. But it must be remembered that keeping lemons indoors must ensure good ventilation. If the ventilation is not good, it is easy to attract rice planthoppers. If the natural ventilation is not good, you can take medicine once every half month to prevent the occurrence of rice planthoppers, so that there can be no pests and diseases.
