The flowers have not turned yellow for 10 years, just because of this

Gardenia

Gardenia, azalea, camellia, etc. are all southern flowers. They originally grow in acidic soil. After being potted, their leaves often turn yellow because the soil is alkaline.

Solution:

You can water the gardenia with some diluted vinegar. Vinegar contains acetic acid, glucose, lactic acid and other substances. Using it to water the flowers can not only adjust the pH value of the soil, but also improve the disease resistance of potted plants and make the flowers grow vigorous and shiny.

1. Choose salt-free vinegar (refer to the vinegar ingredient list to see whether it contains salt).

2. Dilute vinegar with water in a ratio of 1:50.

3. Pour the vinegar solution onto the potting soil.

4. Vinegar solution can not only treat yellow leaves, but also has a therapeutic effect on powdery mildew of roses, sooty mold of peonies, black spot disease of rhododendrons, etc.

Maintenance points:

1. Use a watering can to spray water on the leaves frequently in the morning.

2. Place it on the south balcony, as gardenia needs sunlight to bloom.

3. To promote flowering, you can dilute potassium dihydrogen phosphate with water in a ratio of 1:2000 and then water the flowers.

orchid

There are two main reasons why orchid leaves turn yellow: one is the natural aging of the orchid, which causes the bottom leaves to turn yellow; the other is yellow leaves caused by diseases, such as stem rot and white rot.

Solution:

1. Natural yellowing of leaves is very normal, just pick off the leaves at the bottom.

2. Disease treatment:

(1) Remove the orchid from the pot and observe the condition of its roots.

(2) Use a sterilized blade to remove diseased plants.

(3) Soak the roots in potassium permanganate solution to disinfect.

(4) Put the plant back into the pot and sprinkle wood ash on the surface of the soil, especially the part near the affected area.

Not only orchids can be treated in this way, but most root diseases of other flowers and plants can also be treated in this way.

Maintenance points:

1. When fertilizing, you should use more liquid fertilizer and foliar fertilizer, and the concentration should be lighter than that of other flowers and plants.

2. Sprinkle more water on the leaves in the morning in spring.

3. It is best to place orchids on the north windowsill.

Lucky Bamboo

The leaves of hydroponic lucky bamboo will easily turn yellow when you first buy it, because the environment has just changed and there are no roots to supply nutrients, so the leaves will gradually turn yellow.

Solution:

1. You can put 2 aspirin tablets in the water before rooting.

Because aspirin can decompose into salicylic acid and acetic acid when it comes into contact with water, salicylic acid can kill bacteria and acetic acid can enhance photosynthesis.

2. Add a few drops of ferrous sulfate solution into the water. The ratio of ferrous sulfate: water is 1:1000. It is better to have a dilute solution than a concentrated one.

Maintenance points:

1. Do not place lucky bamboo in places exposed to direct sunlight, such as the south balcony.

2. Clean up the yellow leaves in time.

3. It is best to use purified water for hydroponics, and tap water should be exposed to the sun for three days to disinfect.

Pothos

Green radish can be grown in water or soil. Yellow leaves are caused by many reasons and different reasons should be treated differently.

Solution:

1. Yellowing due to excessive watering: After loosening the soil, place the potted plants in a cool and ventilated place to allow the water to evaporate as quickly as possible.

2. Yellowing due to lack of water: Do not water too much at one time. Water a portion first and then slowly increase the amount of water. Sprinkle more water on the leaves in the morning.

3. Yellowing caused by excessive fertilization: Clean and repot in time. After cleaning the roots of the green radish, replant it in loose and fertile leaf mold.

4. Yellowing due to lack of fertilizer: dilute the liquid fertilizer with water at a ratio of 1:2000 and irrigate the roots.

Maintenance points:

1. Sprinkle water on the leaves of green radish every morning and scrub the leaves frequently.

2. When placing the green radish, avoid air conditioning vents and south windowsills.

Just one small step.

It is no longer a dream for flowers and plants to not turn yellow for 10 years!
