Raising flowers will inevitably encounter yellow leaves, in the case of complete ignorance, the small flowers and green leaves raised at home will become yellow leaves, which is also a problem that makes many flower keepers annoyed, the purpose of raising flowers is to appreciate its green leaves, which become yellow leaves, how to treat it?
Flowers and plants appear leaf yellowing problem, is due to a variety of factors caused, the lack of "trace elements" is the most important, sometimes not we water improperly, or less watering caused, the most practical way to solve the yellow leaves or to add trace elements to the flower, which is the most effective, trace elements is "ferrous sulfate".
Many flower friends are very unfamiliar with ferrous sulfate, this kind of thing is not very understanding, first of all, simply tell you what is ferrous sulfate, ferrous sulfate is in the form of a powder, like the white sugar we eat, the particles are even more delicate than white sugar, there are blue and white two, the concentration of white is high, the concentration of blue is low, usually the blue is used more.
Ferrous sulfate dissolved in water, watered in the flower soil, can significantly improve the pH of the soil, so that the flower soil acidification, biased acidity, improve the soil pH at the same time can add iron to the flower, avoid yellow leaves, ferrous sulfate can be said to be the treasure of raising flowers, 70% of the flowers in the home can use ferrous sulfate.
Family-raised jasmine, gardenia, rhododendron, moon season, etc. are all in need of ferrous sulfate, more accurately they like acidic flower soil, and ferrous sulfate just happens to improve the acidity of the flower soil, ferrous sulfate solvent in water, the molecules will be extremely unstable, the use of time needs special attention, the use of good is the baby, the use of bad becomes a poison.
In addition, flower friends who have raised hydrangeas may have an understanding that a pot of hydrangeas can sometimes bloom two colors of petals, pink, blue-purple these two colors, the problem is ultimately the pH of the soil, acidic soil and alkaline soil will affect the flowering color of hydrangeas. Ferrous sulfate can also play a special effect on hydrangeas.
The concentration of ferrous sulfate that we can buy is very low, all of which are diluted and processed ferrous sulfate, which still need to be diluted again when using, and the ratio I use is in accordance with the ratio of 1:2000ml of water, stirred many times with a small wooden stick until it is completely dissolved in water, and then used to water the flowers.
Spring use once, once can adhere to a year, can greatly eliminate the emergence of yellow leaves, if a large number of yellow leaves appear again, in time to add once, up to 3 times a year, with more easy to burn roots, causing excessive iron in the soil, the flower is harmful.
Ferrous sulfate in the preservation, can be sealed is the best, open breathable is not conducive to preservation, over time will stiffen into a lump, lose the effect.
