Why do peacock arrowroot tips and edges dry up? What causes it?

Peacock arrowroot is only suitable for maintenance and cultivation in semi-shade. It is not suitable for growing and developing under obvious sunlight or on a balcony with better sunlight. The strong amount of solar radiation and light exposure will cause the leaf edges of the peacock arrowroot to turn yellow and wither.

The growth temperature of peacock arrowroot is above 15 degrees Celsius and below 35 degrees Celsius, and the best growth and development temperature is around 22 degrees Celsius. When the daily average temperature in the room is less than 10 degrees Celsius, the soil moisture is weak, or the daily average temperature is higher than 35 degrees Celsius, and the soil moisture is weak, the leaf tip or leaf margin of the peacock arrowroot will also dry up.

The proportion of nutrient composition of bonsai soil is not scientific, and the basal fertilizer is applied to the peacock arrowroot during the growth period, resulting in too much basal fertilizer use and overweight, which reduces the disease resistance of the peacock arrowroot, and the leaves become loose and physiological spots occur on the leaf margins. The poor water absorption of bonsai soil and too much watering lead to the poor growth and development of rhizomes of bonsai soil and the physiological imbalance of peacock arrowroot plants.

Place the peacock arrowroot in a semi-cool place with the sun on the back for maintenance, avoid the source of solar radiation, and place the peacock arrowroot in a sunny place on time"Transfers"。In order to ensure the peacock arrowroot demand for light (not not required, but the demand is small, and the absolute lack of demand will affect the normal growth and development of the plant). The growth and development temperature of A. maura was controlled in the appropriate temperature zone.

Too high and too low temperature is not conducive to the growth and development of peacock arrowroot. When the leaves or leaf margins of the peacock arrowroot wither, you can use amino acid foliar fertilizer and antiatin 2 yuan to mix and apply to regulate the growth and development of the peacock arrowroot, and the growth and development can be restored after one week.

If you water the water barrier for a long time, although the internal structure of the roots cannot be seen, the leaves will be reflected in reality, and the leaves will be curled and dry. Therefore, no matter what season it is, watering cannot be saved, especially in the hot summer, when the water surface evaporates greatly, and the corresponding amount of watering also needs to keep up; The weather has been cold recently, and although it is not necessary to follow the example of summer for watering, the bonsai soil must be kept moist at all times to ensure the healthy growth and development of the plants.

If the sun is too strong or the lack of moisture is caused, watering must be carried out reasonably.

<> peacock arrowroot leaves curl up and dry out because of improper light, watering, temperature, and fertilization. Therefore, placing it in a sunny environment is conducive to the growth of branches and leaves. During the growth period, it can be watered once every 3-5 days to ensure a moist environment for the potting soil, ensure that the most suitable growth temperature is 25 degrees, and apply organic liquid fertilizer once a month during the growth period.

1. Improper lighting.

The dried edge of the leaves of the peacock arrowroot is caused by too much light or long-term lack of light, so it is necessary to maintain enough sunlight exposure when breeding, and place it in a sunny environment to promote photosynthesis. When the light is too strong, it should be shaded appropriately.

2. Improper watering.

The dry edge of the leaves of the peacock arrowroot is caused by the drought of the potting soil or serious waterlogging, so if you want the leaves to regain their vitality, you must water regularly, for example, you can water once every 3-5 days during the growth period to ensure that the potting soil is moist and moist, and gradually reduce the watering in autumn and winter, and the water temperature should be almost the same as the soil temperature.

3. Improper temperature.

The curling edge of the peacock arrowroot leaves is dry because it has been in a high and low temperature environment for a long time, so it is necessary to ensure that the most suitable growth temperature is 25 degrees, and it should not exceed 30 degrees in summer, and take cooling measures. In winter, it should not be lower than 5 degrees, and take warm measures to avoid frost damage.

Fourth, improper fertilization.

Peacock arrowroot leaves curl dry is caused by lack of fertilizer or fertilizer, so we must be regular and reasonable fertilization, regret in the growing period once a month to apply organic liquid fertilizer, fertilizer to phosphorus and potassium fertilizer, nitrogen fertilizer supplemented, which can promote the growth of branches and leaves verdant green.

1. Water yellow: the young leaves are dark yellow and dull, the old leaves have no obvious changes, the branches are small yellow-green, and the new shoots are not long, indicating excessive watering. Depot the flowers, put them in a ventilated and cool shade, and dry the soil ball before putting them back into the pot.

2. Dry yellow: the yellow of lack of water is not the same as the yellow of more water, the yellow of lack of water is the withering and dry leaf tips or edges, and the old leaves are withered and yellow from the bottom to the top, but the growth of new leaves is relatively normal. Pay attention to watering when watering enough, water thoroughly.

3. Burning yellow: strong sunlight directly shines on some shade-loving flowers (such as spider plant, peacock arrowroot, hosta, etc.), which is easy to cause the leaf tips and leaf margins of flowers to wither, and the sunny part of the leaves to appear yellow spots. Move to the pubic area.

4. Fat yellow: the yellowing of flowers caused by excessive fertilization or excessive concentration is manifested in the dry brown appearance at the top of the new leaf, the general leaf surface is thick and dull, and the concave and convex are not stretched, and the old leaves are scorched and yellow. Fertilization should be stopped immediately, and part of the fertilizer should be washed with plenty of washing in severe cases.

Depending on the characteristics of its occurrence, there are the following types.

Situation: First, water yellow. Caused by over-frequent watering, it is characterized by no obvious change in old leaves and yellowing of young leaves; This should be done with immediate water control;

The second is dry yellow. Caused by lack of water and drought, it is characterized by the first yellow leaves from the bottom up, if the lack of water for a long time, the whole plant will be yellow, and even die, should be watered in time;

The third is fat yellow. Caused by excessive fertilization or high concentration; It is characterized by thick, shiny, and uneven young leaves; Fertilizer, cultivation and watering should be controlled;

Fourth, hungry yellow. It is caused by insufficient fertilizer, low fertilizer concentration, and long fertilization interval; It is characterized by the first yellow of young leaves and young stems, and if you do not fertilize in time after seeing this phenomenon, it will also cause the whole plant yellow leaves or even die; For flowers lacking fertilizer, avoid applying a large amount of thick fertilizer at one time, so as not to cause root burning;

Fifth, iron deficiency yellow leaves. Due to the great change of soil fertility conditions, the phenomenon of yellow leaves often occurs in greenhouses, which is characterized by obvious young leaves, light old leaves, yellow mesophyll, green leaf veins, and the formation of a typical network. It can be solved by applying ferrous sulfate aqueous solution, and the method is: 7 parts of cake fertilizer, 5 parts of ferrous sulfate, and 200 parts of water are prepared into multiple liquid water.

The main problem is the water quality, and generally all the pure water used in this flower planting farm is used. The time you pour it with tap water for a long time, salt accumulates in the pot.
