In the growth period of young fig trees, if the base fertilizer is insufficient, it should be fertilized. The method is to apply about 5 kg of decomposed miscellaneous fertilizer to the plant at a distance of about 40 cm from the main root; Potting should be applied at least 1 kg.

Mature trees should be applied with decomposed farmyard manure about 1.5kg, basal fertilizer before and after defoliation, and topdressing should be in the period of vigorous new shoots and rapid fruit expansion. Ficus carica is a fruit tree, which is more tolerant to fertilizers, but more phosphorus and potassium fertilizers should be applied. Generally, the ratio of nitrogen, phosphorus and potassium is 0.5: 1: 1.

Extended data:

Fig trees like warm and humid maritime climate, light fertilizer, no cold tolerance, no waterlogging tolerance and more drought tolerance. In the inland area of North China, if the new shoots are exposed to the low temperature of-12℃, they are prone to freezing injury, and the aboveground parts may die at -20℃, so it is extremely important to prevent cold in winter.

Origin of coastal areas in China. From Turkey to Afghanistan. China was introduced from Persia in the Tang Dynasty, and now it is cultivated in the north and south, especially in southern Xinjiang.

Figs are distributed in other provinces (regions) except Northeast China, Tibet and Qinghai. There are many kinds of plants in the Yangtze River basin and the coastal areas of North China, and only sporadic cultivation is seen in the inland areas south of Beijing.
