Raising flowers is most afraid of yellow leaves, once you see yellow leaves, the next thing is to deteriorate, and finally watch the flowers die, the heart of the thief is uncomfortable... Today Huahua summarized the problems and solutions of yellow leaves, and everyone can deal with it after reading it!
gardenia
Gardenia is particularly prone to yellow leaves, for many reasons, not every yellow leaf gardenia has to be poured with ferrous sulfate, if you do not figure it out, it will kill it.
1, too much watering
The pot that has been wet (more than 2 days of dampness) will make the leaves yellow, and over time the leaves will become black, black spots, and flower buds will fall off.
Solution: ventilation, move to the balcony, window sill open window ventilation, or directly move outside, temporarily stop watering, serious signs of decay, to quickly change the pot to clean up the rotten roots, replanted.
2. Fat burning
Flowering gardenias cannot be fertilized, which will cause the flowers to fall off, the edges of the leaves to dry up as if they have been roasted by fire, and the phenomenon of curling and blackening.
Solution: There has been a fat burning, put the pot on the hollow stool, pour the water thoroughly and try to flush the fertilizer out, and the solid fertilizer can be dug out again.
Note: The flower buds can still be fertilized before they develop color, potassium dihydrogen phosphate 1:1000 mixed with water spray leaves (do not spray flower buds), irrigation root ratio of 1:2000, not too thick.
3. Iron deficiency yellow leaves
Watering alkaline, soil alkalinization will be yellow leaves, at the beginning is the color of the leaf veins is dark, and later even the leaf veins become yellow, that is, iron deficiency, sulfur deficiency yellow leaves.
Solution: Water ferrous sulfate solution once a month, irrigate the roots at 1:2000, do not need to water during the flowering period, and water before and after flowering. Homemade acidic water, can rain, fish tank water, or peel soaked for 12-24 hours, tao rice water to layer clear mixed with 100 times water, edible grade citric acid bubble rusty iron nails · · · · You can also.
Note: After finding iron deficiency yellow leaves, first treat the yellow leaves and then fertilize, and then use other fertilizers after the leaves turn green, otherwise the fertilizer will be more serious!
4. Normal metabolism
The small gardenia on the market with a lot of flower buds, most of them use fertilizer and hormones in the greenhouse, and they do not continue to fertilize after arriving home, and the nutrition is not enough to flower, and they will start to turn yellow from the old leaves.
Solution: remove the small flower buds, retain 3-5 large flower buds, the aging yellow leaves should also be removed in time, if it is serious, all the flower buds will be removed and new leaves will be re-emerging.
Rich bamboo
Rich bamboo is usually hydroponic, the leaves are not good-looking, after finding the reason, a few tricks can be done, very simple.
1. Lack of water
If you have not added water for a long time, the leaves of the rich bamboo have turned yellow, and the poles are wrinkled and yellow, it is a lack of water.
Solution: Quickly add water, replace clean water, remove the yellow leaves (can not be restored), if the pole is yellow and wrinkled, it should also be cut off, leaving only the green and healthy part, and can continue to take root and sprout green buds.
2, too sunny
Rich bamboo likes astigmatism environment, if the sun is too long, the leaf tip will wither yellow, and gradually the whole leaf will turn yellow.
Solution: Move indoors to a location where it cannot be directly sunlight.
3, there are rotten roots
Rich bamboo that has been raised for too long, as well as the group shape in the picture below, is prone to rotten roots, the bottom of the rotten root is yellow, the root system is black brown, the top leaves are yellow, and the leaf tip has signs of brown ulceration.
Solution: Find the rotten root part, cut or cut off the root to re-hydroponic, and the top yellowing place can also be cut off to re-sprout.
4. Place near high-power electrical appliances
Rich bamboo is placed near the TV, refrigerator, air conditioner, if the electrical power is relatively large, the heat dissipation is strong, will be the turtle back bamboo leaf tip roasted dry. If there is no electrical appliance, the air is too dry and easy to dry the tip.
Solution: Change the position again, the dry tip can be cut off.
5. Acid deficiency
The water in the home is alkaline, and the leaves of the rich bamboo leaves that have been raised for too long are dull and yellow, which is caused by acid deficiency.
Solution: Use fish tank water, purified water, cool white culture, or contact rainwater (after precipitation, use the upper layer to clean), you can also add a rusty iron nail to the water, add 1 drop of acid nutrient solution / ferrous sulfate.
6. Frozen yellow
Rich bamboo is very afraid of cold, especially hydroponics, below 10 degrees in the water is very cold, will freeze the roots, and then will yellow leaves, shrugging.
Solution: Put it in a warm room, or turn to soil before cooling down.
rose
Flowers found that the recent yellow leaves of the month that everyone raised are mostly caused by too much watering and lack of nutrition after flowering (hormone seedlings are seriously insufficient nutrition), and it is necessary to control watering and supplement nutrition in time after flowering.
Pictured: After the new seedlings have flowered, the water is stuffy + the lack of nutrients turns yellow
1. Yellow water
Persistent rainy days, no ventilation, too much watering, the pot has been wet, the leaves are easy to dim, yellow, long spots, uneven color.
Solution: water control, ventilation, sunbathing, yellow leaves removed in time, the basin surface can be cleaned up can be sprinkled with carbendazim or grass and wood ash, to avoid too much moisture caused by bacteria breeding.
2. Fat wounds
The monthly season likes fertilizer, but if too much fertilizer is applied, the fertilizer is too mixed, which will cause the leaves to curl, and the edges of the leaves will quickly appear scorched after fertilization.
Solution: solid fertilizer is taken out, after the liquid fertilizer is watered, the pot can be lifted, the water is flushed to flush out the excess fertilizer, and if it is serious, it will be re-soiled.
3. Bacterial disease
The leaves closest to the soil at the bottom are susceptible to bacterial spots. If there is no ventilation after rain or water, it is also prone to bacterial diseases, and leaf spots will expand and infect.
Solution: Remove the diseased leaves in time after discovery, clean the pot surface, sprinkle carbendazim powder or grass and wood ash, bask in the sun and ventilate frequently, and use Schippi to spray/wipe the diseased leaves in serious cases.
4. Insect pests
The leaves appear to be tingling, or the new shoots curl up and wither, which may be red spiders or thrips.
Solution: Before the insect infestation, bury 1-2 spoonfuls of small white medicine near the root for prevention. It can also be buried after the outbreak, but if it is serious, it is recommended to spray it immediately into red killing, and the thrips can be hunted with small white medicine and yellow sticky board.
5. Lack of fertilizer and serious loss of nutrients
Newly bought with flowers in the moon season, especially the small potted plants in the flower market, may be hormone seedlings (nutrition in the greenhouse), after arriving at home, the flowers bloom half of them without nutrients, the old leaves are yellow first, and if they are serious, they will have large areas of yellow leaves.
Solution: pick off some flower buds, leave large buds to flower, after the flowers bloom, you can cut off the bottle to appreciate, by the way cut some fine branches, after cutting 2-3 days sprinkle some Ao Lu 318S fertilizer, medium and large months can be watered with monthly nutrient solution or flower more than 1.
6. Lack of light or yellowing
The moon season is light, the leaves are dim and it is not easy to grow new leaves, but if the high temperature exposure will also quickly scorch yellow, especially after the rain/water exposure, the water stains will refract the burned leaf surface.
Solution: Lack of light to fill the light, move to a sunny position or turn on the fill light at 6-9 o'clock every night, open for more than 3 hours. If you are yellow, even if you remove the yellow leaves, you should shade and put it in the sun after high temperature/rain, and do not shower water during the high temperature at noon.

Fortune Tree
Fortune tree is too easy to yellow leaves, many people will use it as a disposable flower to raise, in fact, it can be saved, do not give up.
1. Yellowing
The leaves of the fortune tree are thin, not sunburned, and where they are directly exposed by the sun, they may turn yellow, burnt yellow, and hollow, and the texture of the leaf veins can be seen, and the hand pinch is somewhat brittle.
Solution: Remove sunburned leaves and move the fortune tree to an astigmatized position to avoid direct sunlight.
2. Too much watering
Water is too much, no ventilation, will cause yellow leaves and rotten leaves, the process is fast and slow, if the water is rotten as soon as it comes up, the edge of the leaf and the tip of the leaf will quickly rot. If it is only slightly stuffy, it will slowly turn yellow.
Solution: The fortune tree is watered once in January, and the evaporation of the home can be watered once every 20 days, more ventilation, and the basin cannot always be wet. If the roots have rotted, remove the rotten part and replace the sand on the basin.
3. Lack of water
The lack of water in the fortune tree is also the other extreme, long-term watering, the leaves are stretched and dried up, if exposed to the sun at the same time, it will soon wither, the leaves are dry, not wet.
Solution: replenish the water in time, put it in a cool place, if the situation is serious, to saw off the stem, take the green stem that is still alive in the middle, and replant it with sand.
4. Bacterial disease
Lack of ventilation, long-term rainy days, indoor dark environment, spraying water on the leaves, may cause bacterial infection, and many yellow spots will appear in the leaves of the fortune tree.
Solution: Remove severe leaves, sprinkle some grass ash/carbendazim powder on the pot surface to sterilize, or spray bilai, which is more effective than carbendazim.
4. Low temperature frostbite
Fortune trees are very afraid of cold, below 10 degrees may freeze to death, frozen to death, the leaves are stretched, gray and dark, is a soft touch.
Solution: Cut off the water (no watering) below 10 degrees, move to a warm place to keep warm, and keep the bag warm at night.
Fuso
Fuso flowers usually have oily green leaves, but it is normal for a little old leaves to turn yellow, if there are more and more yellow leaves, then you have to be careful.
1, the water is more stuffy and yellow

Solution: ventilation, move to the room or window, if there are leaves rotten, you have to dig out to check whether the root system is rotten, if it is rotten, remove the rotten roots, soak carbendazim solution and then replace the soil on the pot.
2, lack of light
Indoors with insufficient light, the leaves of Fuso will faint and turn yellow, especially new leaves, and it is not easy to flower.
Solution: Move to a sunny place, do not need full sunlight, maintain more than 3 hours of light every day, you can also buy a fill light for 2-3 hours.
3. Acid deficiency
Fuso also likes acid, if the new leaves have deep veins and yellowing of the leaf surface, it is alkaline, and acidic water should be poured.
Solution: Pour ferrous sulfate solution or Merlot acidic nutrient solution, you can also take rainwater, fish tank water, homemade peel water to water, pot alkaline can bury some sheep manure to improve.
geranium
Although geranium is very good to raise, there are also many flower friends who report that it is easy to yellow leaves, which is not a big problem for it.
1, there is no basin
On the day of the newly purchased and newly changed pot, there will be some yellow leaves and dry leaves, which is normal.
Solution: less watering, more ventilation, temporarily do not expose to the sun, astigmatism on the line, and then water and dry normally when there are no new leaves yellow.
3, dry yellow, high temperature
If the temperature is high and the light is strong, the yellow leaves of geranium will be more serious, especially if it exceeds 28 degrees, be careful.
Solution: appropriately reduce high temperature exposure, at noon or afternoon when the west sun to shade, move indoor maintenance, high temperature period do not water, do not fertilize.
4, lack of light
Long-term lack of light, the new leaves of the small sky will turn yellow.
Solution: Small days are suitable for maintenance on the window sills with light, and without sunlight, they will turn yellow and will not blossom.
5. Normal metabolism
When geranium grows on the body, the old leaves will turn yellow, which is a normal formation of metabolism.
Solution: You can sprinkle some Aolu No. 5 fertilizer, or water some flowers to do more / potassium dihydrogen phosphate, 1:2000 mixed with water, once a month, the flowering period stops.
Desert Rose
Although the desert rose is a lazy plant, it is also easy to yellow leaves, do not panic after the appearance of yellow leaves, do not fertilize, find the cause, solve and then start normal maintenance.
1, the new seedlings have a little yellow leaves
Newly bought desert roses, a little yellow leaves are normal, especially the bought bare root seedlings, after the pot is slow, will consume some leaves first.
Solution: Place the newly purchased potted plants in a ventilated, bright position at home and water them after 1 week. Bare root seedlings are potted in the fluvo-aquic soil, and they should also be placed in a bright and ventilated position, and then watered after 10 days.
2. Lack of water
Although the desert rose is drought-tolerant, it still needs to be watered during the growth period, and the dehydrated leaves will quickly dry out and turn yellow, fall off, and the stem will become soft and wrinkled.
Solution: When the soil is dry, water, generally once every 1-2 weeks, remember to ventilate after watering, and the soil can be planted with breathable granular soil or sandy soil.
3, too much water, no ventilation, rotten roots
Desert roses are afraid of too much watering, sometimes the water is not much, but not ventilated, the next day the soil is still wet, the leaves are easy to smouldering yellow, serious if the rotten leaves rot roots.
Solution: Remember to ventilate each time you water, evaporate quickly in the sun, do not water at night on rainy days, and try to water in the morning on sunny days. Check whether the bottom of the stomach is ulcerated, if the rotten roots should be dug out and cleaned, let it dry for 1-2 days and then replace the soil on the pot.
4. Frostbite
Desert roses are afraid of cold, and may suffer frostbite below 10 degrees (see Yushu), and the leaves are dull and yellow when frostbite.
Solution: Below 10 degrees can cut off the water, move to a warm place, and then check whether the stem is alive when the temperature rises.
