In May, the weather warms up, and the flowers at home begin to grow, but why do other people's flowers grow wildly, but your family is thin, small, and even yellow leaves? Today, let's solve this problem together!
Gardenia old yellow leaves, pour a little ferrous sulfate!
Many gardenia flower lovers often find that the flowers at home are yellow for no reason, if watering and fertilization are no problem, then there is a good chance that the yellow leaves are caused by iron deficiency!
If the gardenia at home is missing iron, there will be yellowing disease, which is mainly manifested in new leaves, the leaves appear yellowish or white, and then the leaf veins also change from green to yellow, and finally dry up and die!
Once your gardenia has this situation, you have to fertilize it, especially the yellowing phenomenon caused by iron deficiency, and you have to supplement some iron elements, especially the famous ferrous sulfate, which is the favorite of many people to supplement iron.
The use method is also very simple, the 1g ferrous sulfate particles mixed with water 1000 times, mixed into ferrous sulfate solution, sprayed on the gardenia leaves, generally sprayed 3-5 times, and then the leaves that emerge are green and oily new leaves!
Pour a little ferrous sulfate water into the soil and never settle again
Many people know that the soil in the north is basically alkaline, when raising flowers in the south, often because the plants are not adapted to too alkaline soil, and there is a soil compaction phenomenon, affecting root respiration, slightly causing the leaves to yellow, and the entire root system is seriously stuffy and rotten!
Therefore, in the north of the flower, it is best to choose soft, breathable acidic soil, such as saprophyll soil, pine needle soil, peel made of nutrient soil, etc., are common acidic soils.
Of course, the water quality in the north is also alkaline, even if you use acidic soil, if you water alkaline water for a long time, the soil will also appear compacted, so the best way is to regularly water acidic water to improve the phenomenon of potting soil alkali.
We can buy a bottle of ferrous sulfate granules, 1g mixed with 500 ml of water into ferrous sulfate solution, and then give the flowers at home root treatment, generally half a month can be watered once.
After a long time of watering ferrous sulfate, the phenomenon of soil compaction will be significantly improved, and the flowers at home will not have yellow leaves. Such as gardenia, jasmine, bougainvillea, moon season, rhododendron, etc., are acid-loving flowers, can often be poured with a little ferrous sulfate to improve.
Hydrangea pours a little ferrous sulfate, the color is more brilliant!
As we all know, if you want to tone the hydrangea ball, you must follow a principle, that is, acid blue alkali red, that is, often watered acidic hydrangea balls, and the flowers that bloom can better adjust the blue and blue.
If you want to open a blue hydrangea ball, you have to start using acid fertilizer for it from the spring before it sprouts, such as the famous ferrous sulfate, which is the bluening agent that many people use.
Of course, there is also a special hydrangea bluening agent, the main ingredient is aluminum sulfate, its role is mainly to supplement the aluminum element, improve soil acidity, promote the combination of flying swallow and aluminum ions in the hydrangea, so as to achieve the effect of bluening.
You can buy a bottle of ferrous sulfate and aluminum sulfate hydrangea blues, the first week with blues, the second week with ferrous sulfate, so that the use of alternating, the effect of bluening is even better!
Rich bamboo total yellow leaves, give a little ferrous sulfate!
Raising rich bamboo is most afraid of encountering the problem of yellow leaves, especially if you change the water diligently and ventilate it, but why are the leaves still yellow for no reason? To spend flowers to say, it may be a lack of iron!
The method used by many people is to throw a rusty iron nail into the hydroponic bottle, or soak the rusty iron nail in water, and use the iron nail water to raise rich bamboo, but the effect is relatively slow.
The best way is to mix some ferrous sulfate into its water, which can make it quickly replenish iron and avoid yellowing of the leaves of rich bamboo. Just pinch a few grains at a time, don't put too much.
Raising flowers does not want to see yellow leaves
These methods must be memorized
Usually pour a little
The flowers and leaves are evergreen all year round
