First, observe the soil in the basin.
Whether the roots of plants are good or not can be seen from the pot soil. When the weather is fine, we observe the soil after watering for 24 hours. If the surface of the basin soil is slightly white and dry, it means that the root system of the plant is healthy and has good water absorption capacity. If the basin soil is slightly wet, then we need to be alert to the possibility of root rot in plant roots; If the potted soil is still slightly wet after 2-3 days, it can basically be judged that there is something wrong with the root system of this potted plant.
Second, observe the leaves.
When the weather is too humid, it is not good for us to judge whether there is a problem with the root system of plants by potted soil. This is also a good way to observe the leaves. If the plant is in the growing period, the green leaves should have lost their luster and turned gray, and the leaves are still wilting after watering, indicating that there may be problems with the roots of the plant. Plants with fleshy roots, such as Clivia, will have abnormal leaves, longitudinal folds and abnormal leaf shapes if the roots have problems.
Judging the root rot of plants, it is necessary to remedy it in time. First, take the plants out of the pot soil, clean up the soil attached to the roots, and cut off the rotten roots with sterilized scissors. Disinfect the root wound with 0. 1% potassium permanganate solution, or wrap it with clean plant ash and replant it in well-drained soil.
After replanting, we should trim the branches and leaves of the plants. Don't be reluctant. In order to restore the roots of plants as soon as possible, you can cut more branches and leaves and cut off more than half of them. In the recovery period of root system, it is necessary to estimate the soil moisture, do not water, spray more water, and stop fertilization until the root system is completely restored and plants grow healthily.
Sometimes, we can't be sure whether the roots of plants are rotten or not, and we can't be 100% accurate with our eyes. We can't dig up the roots of plants, so what should we do?
Therefore, we should learn how to prevent root rot of plants. To prevent plant root rot, we should start with improving the soil and then control watering, so as to ensure that your plants will not rot. We can add the following substances to the soil.
First, ceramsite
Ceramsite refined at high temperature has good air permeability. Sprinkling it in the basin can strengthen the drainage in the basin, make the soil loose and breathable, and effectively avoid plant root rot.
When using, it is necessary to determine how much to add according to the container, about 3-5 cm, and vermiculite, perlite or river sand is better.
Second, Songta
We can go to parks or roadside green belts to pick up some pine cones and put them at the bottom of flowerpots to become natural filter layers, which is very effective in preventing root rot. When it is slowly fermented and decomposed, it will become a nutrient for plants.
Third, eggshells.
It is convenient to get eggshells. After the egg shell is dried in the sun, it can be broken and mixed into the soil, which can improve the soil structure, supplement trace elements and various minerals, loosen the soil, provide nutrients for plants and prevent root rot. Very practical.
Fourth, loofah sponge.
Many friends use loofah to wash dishes. In fact, it can also be used as a filter layer to be laid at the bottom of the flowerpot, which can prevent the drainage holes at the bottom of the pot from being blocked and effectively prevent plants from rotting roots. Luffa is nitrogen fertilizer after fermentation, which can promote the thicker and greener leaves of plants.
Rotten roots are most likely to occur in summer. Usually, we should observe more plants to ensure their healthy growth. If we find the problem sooner or later, we can solve it. If you are worried that you can't find rotten roots in time, improve the plant soil according to the above four methods. These are all things we can find in our daily life, and they are very convenient to operate.
