Why does the leaf tip of the azalea turn black and yellow and the yellow leaves not grow?
The editor will explain the related content of the green plants about the blackened leaf tip and yellow leaves of the azalea that do not grow, let's understand together.
This is the 917th day of the original article every day.
Yesterday, I shared two basic precautions about potting, but different flowers often have different situations, so the considerations for potting are naturally many.
Those who have bought azaleas, pop up and take a look. I believe most of you have encountered this problem.
There seems to be no problem with the azalea after buying it and repotting it; the flowers will also bloom, but after the flowers bloom, it gradually goes wrong.
The leaves start to turn yellow and wither from the tip, and then the leaves start to fall, and some flower buds that have not opened are charred.
At first, only the leaf tip withers and falls off, but as it progresses, part of the branches wither, and the leaves almost fall off, leaving only a few leaves at the top of the branches, which are still a bit discolored and yellowish.
Those who have encountered this situation, please raise your hand!
Then, why does this situation occur?
Many flower friends think it is because their potting soil is not good and has become alkalized. Of course, this reason cannot be ruled out, but for azaleas bought in the past few months, this is not the main reason.
Think about it, why didn't this situation occur when you bought it? The flowers bloomed well, but problems arose after the flowers bloomed.
Why does the leaf tip of the azalea turn black and yellow and not grow?
Actually, this is a problem of excessive nutrient consumption.
Why does excessive nutrient consumption occur?
To figure out this problem, first, take your azalea out of the pot and take a look.
You will find that the azalea has not grown any new roots, but is still the soil clump from when you bought it, and there is no new growth in the new soil added.
In other words, although we have moved the azalea to a larger pot, the root system of the azalea flower has not grown, and without new roots growing, it is no different from not repotting.
The original soil clump is so small, the nutrients are limited, and after the consumption of a large number of nutrients during flowering, it can be said that the nutrients are almost gone. Moreover, after a few months of care in our hands, the soil clump's fertility and acidity have been washed away, so the azalea has yellowed and lost leaves.
You might say, I added some bottom fertilizer when I repotted!
No new roots growing, the fertilizer in the new soil does not work on the azalea.
So, how can we avoid this situation?
To prevent this phenomenon in azaleas, we must take precautions and prevent it when repotting.
