What is the yellowing of calla lily leaves?
There are many reasons for calla lily leaves yellowing, such as improper watering, excessive fertilization or lack of fertilizer, high temperature and dry air. The solution is to apply the right medicine to the case, watering dry and watering thoroughly, keeping the basin soil moist; fertilization should be based on phosphorus and potassium fertilizer during flowering and nitrogen fertilizer before flowering, and less frequent application; it is appropriate to control the temperature between 20 and 25 degrees Celsius, if the temperature is too high, the plant is prone to yellow leaves; the air humidity should be controlled between 70% and 80%, and the leaves will yellowing when the air humidity is less than 50%. Already yellowed leaves need to be pruned off, because yellow leaves can also compete for water and consume nutrients.
Yellowing of leaves caused by too much watering
[cause of yellowing] calla lilies like to be wet, so they can't be short of water from budding. They should be watered every day, but too much watering will lead to yellowing of leaves.

How is the calla lily plant weak? solve 4 points to make calla lilies glow for the second spring.
The beauty of calla lilies lies not only in its neat plants, but also in its white and delicate flowers. At the end of the year, when the calla lotus florescence comes, we can enjoy a visual feast. However, due to improper maintenance and other reasons, the plant will have some problems, such as calla lily leaves yellowing, weak and so on, how is the calla lily plant weak? The following is by the editor to introduce four solutions, after the calla lily coruscate the second spring.
First, how is the calla lily plant weak? the root is damaged.
In the culture method of calla, we introduce that it has requirements on soil, light, watering and so on, but once these requirements are not met, calla will appear weak symptoms, seriously affecting its ornamental.
As for the weakness of calla lilies, the answer is: calla is a root plant, and its root damage is the main cause of weakness, which is caused by four reasons: improper watering, impermeability of soil, improper fertilization and diseases and insect pests.
1. Improper watering
In the growth process of calla lilies, the demand for water is very high. However, be careful when watering, do not water from top to bottom, because it is easy to water the center of calla lilies leaves, which will cause tubers to accumulate water. At this time, the plant is easy to suffer from bacterial soft rot, resulting in root damage. So why is the calla lily plant weak? maybe you watered it the wrong way.
Solution: watering method should be right, specific operation: with the method of soaking basin, let the water slowly soak into the flowerpot through the basin, so as to soak the soil surface. This way to avoid stagnant water phenomenon, so as to prevent rotting roots. In addition, flower friends can also correspond to a small mound of soil at the root of calla lilies, about 2 centimeters, so as to avoid pouring directly into the roots when watering.
2. The soil is not aerated.
In addition to improper watering, the soil is too wet and airtight is also one of the reasons for the weakness of calla lilies. Calla lilies like loose and breathable soil and avoid impermeable and poorly drained yellow clay. Once you use the soil improperly, or the tubers are buried too deep, it will lead to rotting roots, which will lead to plant weakness. Not only that, the root system caused by excessive dryness of the soil will also lead to plant weakness.
Solution: it is found that the plant is weak caused by the soil. Flower friends should dig out the root tuber and eliminate the rotting part of the root, then soak it in carbendazim solution and 1000-fold potassium permanganate solution for 30 minutes, dry and plant again in the pot. Note: if the basin soil has been infected, replace it directly. After changing the basin, cut the leaves and stems of calla lilies as short as possible to promote root development.
3. Improper fertilization
In the process of calla lily growth, the optimum temperature is 22 ~ 30 ℃. Once it is lower than 10 ℃ or more than 30 ℃, calla will enter the dormancy period, when the plant listens to grow. If they are new friends, they will not care about it and still apply fertilizer as usual. This will definitely not work, and the result will be rotten roots, which will lead to plant weakness.
Solution: read the above content, calla lily plant is weak how to return a responsibility, obviously is too much fertilizer. At this time, flower friends can adjust the temperature to make calla lilies wake up from the dormant period, do not apply fertilizer at this stage, a period of time will glow the second spring.
4. Red spider infestation
In the prevention and control of calla lotus diseases and insect pests, we introduce one of the pests of calla lilies, that is, red spiders, which will absorb plant juice, resulting in nutrient deficiency, plant weakness symptoms, serious will lead to death.
Solution: open windows for ventilation, usually pay attention to frequent spray, maintain air humidity. Found that red spiders, flower friends can use dimethoate 800 times liquid spray branches and leaves, focusing on the back of the leaves.
People who lack energy will be tired, weak all over, in fact, plants lack nutrients will be the same, this is the root cause of plant weakness. After reading the above, I believe we all know how the calla lily plant is weak. The solution is not difficult. If you love flowers, you must remember that when you encounter such a situation, you can solve it immediately. Finally, may your calla lilies blossom beautifully!
