How to prevent plant root rot and what are the symptoms of root rot?

How to prevent plant root rotToday, the editor introduces how to prevent plant root rot and the manifestations of flower knowledge related to root rot, let's get to know it together.Home environment is inseparable from the decoration of grass and plant, placing 1 to 2 pots of grass and flowers in each room can make the environment vivid and lively, and relax both body and mind. However, potted flower cultivation is not simple and requires us to invest some time, energy, and money. Not only should we pay attention to watering, fertilizing, and lighting, but also soil issues. If the soil is not fertile and as hard as stone, it will definitely result in the death of a pot of plants. So, do you know what signals in the flowerpot indicate that it's time to repot immediately? Today, I'll tell you about these four signals. If you wait any longer, you'll end up with an empty pot.First point, white frost on the surfaceIf there are white crystal-like substances on the soil surface, it indicates that the soil may have become alkaline. Because most plants prefer to grow in slightly acidic and well-draining soil, soil alkalization can affect the absorption capacity of roots for nitrogen, phosphorus, potassium, and iron elements, resulting in yellow leaves, such as gardenias and jasmines, which are prone to iron deficiency yellowing. If there is something like this on the soil surface, change the pot as soon as possible.Second point, water does not penetrateWhen watering, you may notice a phenomenon that water does not penetrate downward for a long time. If this phenomenon occurs, it indicates that the soil may be compacted, and it can also be seen from the surface, which is definitely hard soil like stone. After watering, it is prone to waterlogging and can easily mislead people to pour half the water, which can also lead to the roots being unable to absorb moisture and die from dehydration. Over time, the plants will become increasingly difficult to maintain, so it's important to repot promptly if you notice this.Third point, flower roots growing out of the drainage holePotted plants should be changed every two years. Some people are lazy about growing flowers and use the same soil for three to five years, resulting in the emergence of non-flowering and rigid seedlings. Even if the soil chosen at the beginning is nutritious and well-draining, over time, the nutrients will be depleted. Moreover, statistics show that after one year of soil use, most of the nutrients are gone. As the plant grows larger and the roots longer, the pot cannot accommodate them, causing them to grow out of the drainage hole. This is a signal to repot, and if you notice it, you must act decisively.How to prevent plant root rotFor example, the Dracaena reflexa we often grow initially grows quickly, but after a period, it grows slower and slower. This is likely due to limited space and insufficient nutrients in the soil. Therefore, for fast-growing plants like Dracaena reflexa, it is necessary to repot and change the soil every year.Fourth point, white hair in the flowerpotWhen we first plant flowers, we choose a pot of well-draining, fertile soil. However, such soil may contain some bacteria and eggs. If the maintenance is improper, such as poor ventilation or high temperatures, once there is sufficient moisture, bacteria and eggs will multiply, resulting in a layer of white hair on the surface. This is likely caused by mold. In the short term, it may not cause significant impact, but over time, it may lead to root rot.So, in this case, it is also necessary to repot and change the soil without delay. Therefore, when changing the soil, it is recommended to add some fungicides, such as carbendazim. After watering, it is important to ventilate more, especially when temperatures are high. For drought-tolerant plants, be sure to water less.The above is all about how to prevent plant root rot and its manifestations. Green plant enthusiasts might as well refer to this aspect.
