Don't panic if your potted plant has yellow leaves - just pour a little something from the kitchen and it will quickly recover, staying green for 10 years

Many friends grow plants at home and don't know why the leaves turn yellow. Actually, there are several great things at home that can treat yellow leaves, very convenient and simple.
First, vinegar without salt
The vinegar we eat is all acidic. For some acid-loving flowers, such as gardenia and azalea, you can use salt-free edible vinegar diluted 50 times with water and spray it on
This can greatly improve the yellow leaf condition. It can also be used to water flowers, playing a role in improving the soil
Second, add a little white sugar.
White sugar isn't just for eating - it's great for growing plants too!
Sugar water can promote rooting in water-grown plants, add nutrients to potted plants, and reduce yellow leaves. The sugar solution is beneficial to microbial activity and is very effective for woody plants like Chinese rose and camellia, and herbaceous plants like spider plant and pothos.
When taking cuttings, you can add a little white sugar to make a homemade rooting agent, and roots will grow like crazy
Third, iron nails from home.
The rust on iron nails can release iron ions in water, supplementing iron for hydroponic plants and preventing yellow leaves. It is especially effective for lucky bamboo.
Just throw a piece of iron nail into the hydroponic bottle, but make sure the nail is rusty - a perfectly intact nail will have no effect.
