The reason why fig tree leaves turn yellow and fall off in sequence is mainly the following three points:
1, the potting soil is unreasonable?
The fig's root system is very developed, the nutrient demand for the soil is high, if the soil is too poor in nutrients, can not provide sufficient nutrients, which will cause the fig's leaves to appear yellow or rolled leaves phenomenon.
Family potting soil can be adjusted in proportion to the proportion of 4 portions of leaf litter, 4 portions of garden soil, 2 portions of river sand, in addition to 5% composted cake fertilizer or a small amount of multi-polymer composite fertilizer particles, to ensure that the soil has sufficient nutrients for the growth of figs.
2, watering unreasonable
If the daily maintenance, to the fig watering too much, easy to let the fig's root shriveling and death or the phenomenon of rotting roots, once the fig's root problems, nutrients can not be sent to the ground plant, which will let the fig leaves appear yellow phenomenon.
Daily watering of figs must be reasonable, you can follow, in the spring and fall watering 2-3 times a week, keep the soil of the pot plant moist, to the summer need to water once in the morning and evening, to provide enough water, to the winter can be watered once every half a month can be watered, so that the fig tree can successfully pass through the dormant period.
3, temperature discomfort
It is important to know that the fig is not hardy, like warm plants, if the temperature is too low in the winter, not in time to do a good job of warming measures, then the leaves of the fig will appear leaf yellow curling phenomenon.
Generally in the fall after the frost, you can move the fig to indoor care, the appropriate temperature of the fig in 5-20 ℃, so the winter temperature should be controlled within this range. In the summer, we should also avoid the fig to be exposed to the sun, the temperature control in 22-28 ℃ is more suitable.
Expanded information:
The planting method of the fig
A, soil
The fig's root system is more developed, so if it is potted, you have to choose a larger pot, need more soil and nutrients, can be compared to put under the pot of rotting soil, to keep the soil loose and breathable and drainage.
Two, fertilization
The growth of figs can not be separated from fertilizer, in the planting of the initial to be put into the base fertilizer to the rotting of the fertilizer cake is given priority to, in the growth period to appropriate supplement nitrogen fertilizer, potash, flowering and fruiting period to phosphorus fertilizer is given priority to.
Three, pruning
The growth rate of figs is relatively fast, in the growing season to prune regularly to limit the height of the plant to control nutrient loss. Especially planted in pots of figs, be sure to control its height, to promote its more lateral branches.
