What s the deal with the yellow edge of plant leaves? What fertilizer to use for yellowing of the ed

The details are as follows: 1. Watering too often in the summer to water the flowers in the pot, the number of times is too frequent, the amount of watering is too large, coupled with the poor drainage of the potting soil, so that the water in the pot is too wet, the potting soil is too wet for a long time, and the external air can not enter the potting soil, resulting in soil hypoxia, so that the respiration of the roots is blocked, various physiological functions are weakened, and the resistance is reduced. In addition, anaerobic bacteria are active in the anoxic environment, producing harmful gases and poisoning the root system, causing the plant to rot roots, turn yellow leaves, and seriously cause the whole plant to die.

Second, watering water and potting soil is alkaline, especially in the north, watering more tap water, river water, well water, water mostly contains saline-alkali components, and if the plant is acidic flowers and trees, long-term adaptation to acidic soil has been growing well. If you switch to alkaline soil or water the flowers with alkaline water, the potting soil will become alkaline, resulting in the weakening of jasmine growth and yellowing of branches and leaves.

Third, the long-term lack of soil and fertilizer can also lead to the yellowing of plant leaves, potted plants due to long-term soil change, coupled with frequent watering and rain, fertilizer loss and can not be supplemented, the fertilizer of the potting soil does not meet the nutrients required by the plant, so that the plant is in a state of hunger, forming a "hungry yellow".

Nitrogen deficiency: If nitrogen deficiency occurs, the leaves will become pale green or yellow-white, the branches will be thin, and the new leaves at the top will gradually become smaller and easy to fall leaves. Phosphorus deficiency:

Insufficient phosphorus fertilizer can hinder the formation of crop flowers, making crops small and few, and prone to poor fruit development. Potassium deficiency: lack of potassium nutrition, slender stems, severe leaf tip leaf margin scorched, leaf wrinkled, old leaf leaf margin curled yellow and fire color and easy to fall off.

Magnesium deficiency: Magnesium deficiency first yellows between the veins of old leaves, and gradually spreads to new leaves in the upper part, the mesophyll is yellow while the veins are still green, and various spots appear between the veins. Iron deficiency:

The symptoms of iron deficiency are similar to those of magnesium deficiency, except that iron deficiency first yellows between the veins of the new leaves, the veins remain green, and then develops into yellowing or whitish turning of the entire leaf. Manganese deficiency: The symptoms of manganese deficiency are similar to those of iron deficiency, between the veins of the leaves.

It's not a lack of fertilizer. Because the seedlings are small, they don't absorb a lot of fertilizer. The yellowing temperature of the leaf edge is not enough to be at the lowest critical temperature and gradually lose green, and the other possibility is that it is placed indoors for a long time, and the strong light will also cause the leaf edge to wither yellow.

Cyclamen leaves turn yellow, so don't rush to fertilize them, because yellow leaves are not caused by a lack of fertilizer, but by 3 other reasons.

Yellowing of the edges of the leaves may indicate potassium deficiency.

Sufficient potassium fertilizer will make the leaves smooth and flat, otherwise there will be uneven leaf surfaces, and the edges of the leaves will slowly appear yellow and withered. At this time, it is necessary to supplement potassium fertilizer in time, and apply plant ash or bika potassium dihydrogen phosphate at the bottom of the pot to make the potassium fertilizer sufficient, and the plant leaves become flat and smooth back to the original.

1.The leaves of the plant are yellow, if it is caused by alkaline water and soil, acidic soil should be provided, and acidic substances should be added dropwise.

2.If it is caused by improper water and fertilizer, it is necessary to do a good job in water and fertilizer management, reasonable watering and fertilization.

3.If the soil is not breathable, raise it for about two years to change the potting soil and loosen the soil in time.

4.If the temperature is too high or too low, adjust the temperature and try to keep it within the appropriate range.

5.If it is caused by infection with pests and diseases, it is necessary to strengthen prevention at ordinary times and timely after infection.
