A common cause of yellowing of bromeliad leaves.
Overwatering: If you water the pineapple flowers too much, it will cause the potting soil to be moist for a long time, the root system will rot, hinder normal respiration and the absorption of water nutrients, and the leaves will turn yellow and fall off.
Drought and dehydration: If you do not water the pineapple flowers in time, it will affect the absorption of nutrients, which will lead to dull and dull leaf color, and the leaves will wilt and droop.
Long-term defertilization: If you do not apply ammonia fertilizer to pineapple flowers for a long time, or do not change the potting soil, it will lead to insufficient nutrients such as soil nitrogen, which will cause thin branches and leaves and thin yellow leaves.
Excessive fertilization: Excessive fertilization of bromeliads will cause plant root burns, and the plant will have new leaves with hypertrophy, unevenness, and dry old leaves, and burnt yellow and fall off.
The yellowing of the leaves of the bromeliads may be due to the low humidity in the air, or the alkalinity in the irrigation water is too strong, or the calcium and sodium content of the penitent is too high, causing the roots of the plant to rot.
Treatment method for yellowing bromeliad leaves.
1. If the yellowing of bromeliad leaves is caused by excessive watering, the watering should be controlled immediately and the soil should be loosened to make the soil aerated well.
2. If the yellowing of bromeliad leaves is caused by drought and dehydration, it needs to be watered in time and appropriately, and then watered normally after gradual recovery.
3. If the yellowing of bromeliad leaves is caused by long-term defertilization of Bihui potatoes, the pot should be changed immediately, replaced with new loose and fertile cultivation soil, and the thin decomposed liquid fertilizer should be gradually increased.
4. If the yellowing of bromeliad leaves is caused by excessive fertilization, the fertilization should be stopped in time, and the amount of watering should be increased to dilute the fertilizer.
How to prevent yellowing of bromeliad leaves.
Watering: You don't need to water too much when maintaining bromeliads, as long as the surface of the basin is slightly dry, sprinkle properly in summer to improve the humidity of the environment, late spring to autumn is the period of its vigorous growth, you can increase the amount of watering appropriately, don't let the potting soil wet in winter, it is best to keep the potting soil slightly dry.
Fertilization: In order to prevent the leaves of bromeliads from turning yellow, it is also necessary to pay attention to reasonable fertilization, and in the period of vigorous growth, fertilizer should be applied once every one to two weeks, and the fertilizer should not be too strong.

Summary. Hello, the leaves of bromeliads turn yellow, you can use calcium, magnesium and phosphorus fertilizers or spray magnesium sulfate solutions.
Hello, the leaves of bromeliads turn yellow, you can use calcium, magnesium and phosphorus fertilizers or spray magnesium sulfate solutions.
The yellowing of the leaves of bromeliads may be due to the alkalinity of the irrigation water quality is too strong or the calcium and sodium content is high; The air humidity is too low; Excessive fertilization or high concentration of liquid fertilizer leads to the accumulation of salts in leaf tips, resulting in salt damage, protoplasm splitting and dehydration; Poor drainage of the substrate leads to root rot, and the water cannot be sufficient** to the leaf tips, etc.

The pineapple flowers are dried and the leaves are still green, so you can pick the flowers.
Pineapple, also known as pineapple, is a bromeliad plant in the bromeliad family.
It is cultivated in Guangdong (Zhanjiang Leizhou, Zhongshan Shenwan), Hainan, Taiwan, Fujian, Guangxi and Yunnan.
Pineapple stems are short. Leaves numerous, rosette-arranged, 40 to 90 cm long, 4 to 7 cm wide, apex acuminate, entirety or acutely toothed, ventral green, dorsal pinkish-green, margins and apex often maroonish-red, leaves born at the top of the inflorescence smaller, often red.
The inflorescences are drawn from the leaf clusters, like pine balls, 6 to 8 cm long, enlarged when fruiting; bracts green at base, pale red on upper half, triangular-ovate; sepals broadly ovate, fleshy, reddish at apex, about 1 cm long; The petals are oblong, pointed, about 2 cm long, purplish-red in the upper part and white in the lower part.
The polyanthrocarpus is fleshy and more than 15 cm long. Flowering period: summer to winter.
Pineapple can be eaten fresh and processed, can be processed into canned pineapple in sugar water, pineapple juice, etc., pineapple fresh fruit can also be quick-frozen: after washing, peeling, core, cutting, freezing treatment at minus 35, stored at minus 20 low temperature, can make nutrition and fresh pineapple the same. In addition, pineapple processing by-products can be used to make sugar, monosodium glutamate, citric acid, etc.
Pineapple is rich in nutrients, including sugar, protein, fat, vitamin A, B1, B2, C, proteolytic enzymes, calcium, phosphorus, iron, organic acids, niacin, etc., especially vitamin C has the highest content.
Pineapple is sweet, slightly sour, slightly cold, and has the effect of clearing heat and relieving heat, quenching thirst, and facilitating urination. In addition, fruit juice also contains an enzyme similar to gastric juice, which can break down protein and help digestion. It has different effects on physical health.
**Pineapple contains almost all the vitamins that people need, 16 kinds of natural minerals, and can effectively help digestion and absorption. The secret of pineapple** lies in its abundant juice, which effectively acidifies fat.
Cleansing the stomach and intestines bromelain can effectively break down the protein in food and increase gastrointestinal peristalsis.
Beauty-rich vitamin B can effectively nourish the skin, prevent dryness, moisturize the shiny hair, and at the same time can eliminate the tension of the body and enhance the body's immunity; Method: Its pulp can be used as **, which is the sweetest care product.

Pineapple leaves dry up solution:
Bromeliads like high temperature, moist, semi-shady environment, the leaves are all withered may be the temperature is low, no watering, or the light is too strong, it is recommended to put it in a place with high temperature, humidity, the sun is not very strong, patient cultivation, long watering, from the late spring to the autumn growth period, you can increase the amount of watering appropriately, you can also fill some water in the leaf tube, change the water once in half a month, so as not to deteriorate and stink. Foliar water is often sprayed. In winter, it is advisable to dry the pot, but not too dry.
From May to September, nitrogen fertilizer should be applied once a week, and phosphorus and potassium fertilizer should be appropriately applied before flowering to promote large and colorful flowers. When flowering, do not irrigate the tube and store it in a place away from sunlight to prolong the flowering period. After flowering, the flower stalk must be cut off to reduce nutrient consumption.
Do not fill the tube with water in winter. The root system of ornamental pineapples is not very developed, there is no taproot, and some roots also like to contact with air, so planting in small pots and shallow pots will grow and develop better than using large pots and deep pots. It is best to add a small amount of garden soil to the potting soil, or mix it with peat and perlite.
After flowering, the central leaf cluster dies and the next daughter plants continue to grow. When the height of the plant is 15 cm, it can be removed from the mother plant and replanted. In doing so, it can only be "passed on from generation to generation", and the number of breeding is limited.
Therefore, it is best to combine the spring repotting, cut the small tuber cuttings that grow out of the tuber part of the mother plant, or use the young shoots germinated from the roots of the old plant to grow roots, all of which should be protected from shade and moisturizing, and when the root system grows to 2-3 cm, it can be planted. If cultivated properly, a mother bead can reproduce about 10 plants per year.

Ornamental pineapples only bloom once in their lives, and after flowering, they will grow one to several buds at the base of the old plant, and they should not be divided too early, otherwise it is not easy to survive.
The method of dividing the plant is: first cut off the flower stem from the base, and then leave 5 8 cm of the leaves of the old plant, and remove all the rest, leaving the base of the leaf just to form a cylindrical water storage, do not touch the small buds when cutting.
When the bud is about 10 cm high, then use a sharp knife to gently cut from the bud and the mother plant connection, plant the small bud into the potting soil prepared with humus, and after careful maintenance for a year, it can bloom gorgeous flowers.
The ornamental pineapples bought by flower friends are generally in the flowering period, and as the flowering period slowly passes, the pineapples will slowly die, and the leaves turn yellow as a matter of course, which is a normal situation.
Some flower friends will say, then why don't you see the evil buds at the bottom? Flower friends should know that pineapple is originally a tropical flower, although it can be bought in the flower market, but the production environment is carried out in the greenhouse, this kind of flower as an ornamental flower can also, ordinary family breeding is not long-term, the leaves are dry and cracked, curly, yellowing and other conditions are very normal.
In addition, many flower friends have a complex, that is, no matter what flowers they buy, they hope that the flowers can be raised from generation to generation, in fact, this is not in line with science, because although now you can see the flowers in the south and the north, but they are all produced in the greenhouse, to the flower friends' homes, it is still an ordinary environment, so flower friends do not need to force it.

1. Reduce watering
Reason: If the pineapple is watered too much, it will be soaked in stagnant water, the roots will be soaked, and the leaves will turn yellow. Workaround:
Watering is a big problem. Don't pour too much. In general, the surface of the soil is slightly dry and you can water.
Don't overdo it.
2. Reduce light:
Reason: Air pineapples can not be exposed to the sun, and the leaves are easy to turn yellow when exposed to the sun for a long time, as long as there is enough light. Workaround:
Can be placed on the balcony. When the light is strong, you can block it properly, and you can also move its position slightly. Conversely, it should not be left in a cool place for a long time.
You should have the right light.
3. Pay attention to ventilation.
Reason: It is easy to suffocate in a completely enclosed environment, and the leaves turn yellow. Solution: Proper ventilation, or occasional windows at night, is conducive to its growth in a ventilated environment.
4. Warm up and keep out the cold.
Reason: The most suitable temperature for the growth of air pineapple is 20-25, and the minimum temperature should not be lower than 5. It is easy to get frostbite in a low temperature environment, and then the leaves turn yellow.
Solution: In a low temperature environment, you can take some measures to keep warm, or put it in the sun when the sun is good, and properly control watering.

Leaf blight. Symptom.
Leaf blight mostly occurs from the leaf edge and leaf tip, the lesions are irregular from small to large, reddish-brown to gray-brown, the lesions are connected into large blight, the dry area reaches 1 3-1 2 of the leaves, and there is a deeper band than the lesion at the edge of the lesion; The boundary between disease and health is clear. Later, some small black spots are produced on the lesions. Such as osmanthus leaf blight (also known as blight), plum leaf blight, aster leaf blight (also known as spot blight). >>>More
1. Gardenia likes fertilizer, should be applied with balanced and peaceful organic fertilizer, cooked soybean cake, sesame sauce residue, peanut bran, etc., after fermentation and rotting can be acidic fertilizer, but can only be applied diligently with thin fertilizer, avoid thick fertilizer, raw fertilizer. Thick fertilizer can easily lead to damage to the root name and even rot. The reaction after root rotting is on the leaves. >>>More
