Yang Wen bamboo remember these three points are no longer afraid of yellow leaves, rotten roots

Recently, many flower friends have left messages asking the question of asparagus, either yellow leaves or rotten roots! In fact, asparagus is very easy to raise, flower friends raise asparagus yellow leaves, rotten roots, the fundamental reason is that the following three points have not been done well!

First, too much watering

Asparagus leaves are relatively small, the demand for water is not much, if we water it too much, basin soil can not dry for a long time, it will cause its root hypoxia, causing a large area of yellow leaves, rotten roots!

Second, there is too much light

I have told you before that for general foliage plants, we'd better put them in a place of bright astigmatism, that is to say, there are windows, but the sun can't shine!

Asparagus is a shade-tolerant plant, we usually put it in the bright astigmatism is the best, if you want to put it in the direct sunlight, within a day or two, all its leaves will be yellow!

Third, iron deficiency yellow leaves

Asparagus likes slightly acidic soil. If the soil is too alkaline, there will be iron-deficient yellow leaves, so we give it ferrous sulfate once a month to adjust the acidity of the soil!

But in the use of ferrous sulfate, do not overuse, we "would rather less than more", less can be supplemented, but once excessive use, it will burn roots!

In addition, we need to remind you that asparagus is not tolerant to fertilizer. If you apply a little more fertilizer, you will have yellow leaves and burn roots! Therefore, if it is asparagus bonsai, we'd better not fertilize it. If it is a climbing asparagus, we should give it a three-element compound fertilizer once a month, or "better less than more"!
