What about potted kumquat leaves? Reasons for potted kumquat leaves

Reasons for potted kumquat leaves:

First, if the dots are yellow, it may be red and yellow spider damage.

Second, the lack of nutrients, for the time being, should be the nutrient deficiency of potted kumquat deciduous nitrogen.

Third, potted kumquat leaves like an acidic environment, if long-term use of tap water can cause iron deficiency yellowing.

The corresponding prevention and treatment methods can be selected according to the above reasons:

First, the prevention and treatment of mites (red and yellow spiders), the family can use tomato juice to control water, and also can buy acaricides in pesticide stores.

Second, the potted kumquat can be sprayed with 0.2--0.3% urea + 0.2% potassium dihydrogen phosphate to improve the leaf surface yellowing.

Third, potted kumquat water can be added 0.2% ferrous sulfate, improve the soil environment, do not pour too much water, especially in winter. Potted kumquat leaves are mainly lack of light. Increasing the light will not drop the blade, and the room temperature in the northeast is high, but the air is very dry.

Potted kumquat maintenance method:

Kumquat is a xerophytic plant in Xiyang and Xiwei acid soil. It is more cold-tolerant, barren, fearful, and too arid. The four elements of domestic kumquat should be done well:

1. Potted kumquats should have plenty of sunshine, because no plants have no light (line) and no photosynthetic nutrients, no evaporation and no physiological circulation between branches, leaves and roots (pot plants need to be moved in winter) To prevent freezing roots from dying, the room must be placed in front of a well-lit window; and indoors in winter, the indoor humidity should not be too large).

2. The watering of potted kumquats in the growing season needs to be in accordance with the principle of natural rain and rain, “no watering, no pouring, pouring and pouring”. The wintering period is due to the small amount of water required for evaporation, and it must be absolutely controlled when moving into the room. Watering, just keep it slightly moist to prevent suffocation and rotten roots.

3. Potted kumquat wintering has stopped growing in the dormant period, and must not be fertilized; it is appropriate to use light micro-acidic organic fertilizer in the growing season, and any plant is afraid of thickening of the roots (fertilizer is inorganic neutral or alkaline) Fertilizer, long-term application will cause the potting soil to be knotted, and it is easy to burn roots and dead plants when applied improperly).

4. In order to promote the growth of potted kumquats and many results, in the growing season, it is necessary to place more sunlight in the sunny place, and always make the shade of the pots to prevent the roots in the pots from being straight in the sun. It is easy to get over 37 degrees in the sun and the roots of heatstroke (the roots of plants are more than 37 degrees).
