Gardenia, azalea, camellia, etc. are all southern flowers, originally grown in the acid soil, potted, often because the soil is more alkaline and leaves yellow.
Gardenia can be watered point diluted vinegar, vinegar contains acetic acid, glucose, lactic acid and other substances, used to water flowers can not only adjust the pH value of the soil, but also improve the resistance of potted plants, so that the flowers grow strong and bright.
1. Select vinegar without salt (refer to vinegar ingredients list for salt content).
2. Dilute vinegar with water in the proportion of 1:50.
3. Pour vinegar solution on the basin soil.

4. Vinegar solution can not only treat yellow leaves, but also the powdery mildew of rose, the anthracite disease of peony, and the black spot disease of azalea.
1. In the morning, spray water on the leaves with a watering can.
2. Put it in nanyangtai, gardenia blossom needs sunshine.
3. Accelerating flowers can be diluted with 1:2000 potassium dihydrogen phosphate and watered.
There are two main reasons for the withered and yellow leaves of orchids: one is the natural aging of orchids and the yellow leaves at the bottom; the other is the yellow leaves caused by diseases, such as stem rot and white silk disease.
1. Natural yellow leaves are very normal. Just remove the bottom leaves
(author: Junda 1988 source: how to raise orchids)
2. Disease treatment:
(1) take off the pot and observe the root system.
(2) use a sterilized blade to remove the diseased plant.
(3) soak the roots in potassium permanganate solution to kill the virus.
(4) re-enter the basin, and sprinkle the surface of the basin soil, especially the part close to the affected area, with vegetation ash.
Not only can orchids be saved in this way, but most of the diseases of the roots of other flowers and plants can also be treated in this way
1. Liquid fertilizer and foliar fertilizer should be used for fertilization, and the concentration should be lighter than other flowers and plants.
2. In the spring morning, more water should be sprinkled on the leaves.
3. Orchids are best placed on the North windowsill.
It's easy to get yellow leaves when the hydroponic bamboo comes back, because the environment has just been changed, and there is no root to supply nutrients, the leaves will gradually turn yellow.
1. Put 2 aspirin tablets in water before rooting.
Because aspirin with water can be decomposed into salicylic acid and acetic acid, salicylic acid can kill bacteria, acetic acid can improve photosynthesis.
2. Drop a few drops of ferrous sulfate solution into the water, with the proportion of ferrous sulfate: water = 1:1000, rather dilute than concentrated.
1. It is not allowed to place the bamboo in the direct sunlight such as nanyangtai.
2. Clean the yellow leaves in time.
3. It is better to use pure water for hydroponics, and tap water should be exposed to the sun for three days to kill virus.
There are many reasons for the yellow leaves. Different reasons should be treated differently.
Solution:
1. Too much watering and yellowing: after loosening the soil, put the potted plant in a cool and ventilated place to make the water evaporate as soon as possible.
2. Lack of water and turn yellow: do not pour too much water at a time. First pour some water, slowly increase the amount of water, and spray more water on the leaves in the morning.
3. Excessive fertilization and yellowness: clean and replace the basin in time, and plant the root system of the pothos into the loose and fertile rotten leaf soil.

4. Lack of fertilizer and yellowing: liquid fertilizer is diluted with water according to the ratio of 1:2000, and root filling is carried out.
1. Sprinkle water on the leaves of pineapple every morning, and often scrub the leaves.
2. Keep away from the air conditioning port and South windowsill when placing the pothos.
Just a little step
Flowers and plants for 10 years are not yellow leaves are not dreams anymore!
