Cultivation methods of orange trees:
First, potted citrus reticulata likes slightly acidic soil. When changing pots in spring, keep some soil to protect the roots and prune too many old roots. The mixture of 8 parts humus and 2 parts slag is the best!
Second, the principle of watering is dry and wet, and watering should be thorough. When the pot soil is slightly dry during flowering, such as when young fruits and soybeans are big, it can strengthen fertilizer and water, and oranges like humid environment. During the exhibition period and the peak growth period, water should be sprayed around the leaves and flowerpots frequently.
3. Potted oranges are like fertilizer. In addition to fertile soil, in the growing period, every 7 ~ 10 days, 1 times decomposed fertilizer water is poured, with the concentration of 1 liquid fertilizer and 3 parts clear water. Pay attention to a small amount of fertilization, organic fertilizer must be fully decomposed, and the application interval of solid fertilizer is generally 1 month. No fertilization during fruit viewing in winter.
4. The main dangerous insects of potted oranges are aphids, scale insects and red spiders, which can be used to clean flowers once and kill them. Oranges like acidic flowers, and a small amount of ferrous sulfate can be added during preparation and cultivation, or a few drops of vinegar can be dropped when watering. Conducive to green leaves, not falling flowers and fruits.
5. Potted orange plants like light, and they can be placed in sunny places during the growing period, and basking in the sun in summer can provide a little shade. When you look at the fruit in winter, put it in a bright place indoors.
