How to determine when to repot a plant
Today, I will introduce to you how to determine when to repot a plant and the detailed knowledge of the four situations related to repotting plants. This is a very useful tip, so I recommend you save it for future reference!
After the beginning of spring, the weather will get warmer and warmer, and flower enthusiasts will start to repot and change the soil for the flowers in their homes. However, there are also many people who, although they have many flowers at home, do not know which ones need to be repotted and which ones do not. After all, repotting all of them at once requires a lot of work, and repotting flowers that do not need it can be harmful to their growth.
Although spring is a good season for repotting flowers, it is not necessary for all flowers to be repotted and changed. Only those that have not been repotted or changed soil for several years or have been growing poorly for a long time need to be repotted and have their old and weak roots pruned. If the potted flowers at home show any of the following four situations, it is time to consider repotting.
The flowers do not grow for a long time
Many flower enthusiasts have flowers that, although they have managed to keep them alive, do not thrive and show no signs of growth or new buds. This is what we call a stagnant seedling, and it will not recover to a vigorous growth if left unattended, so it needs to be repotted.
For stagnant seedlings, you should trim the tangled branches and then remove the plant from the pot, prune the old and weak roots, and then disinfect the roots with potassium permanganate or carbendazim. After that, replace it with loose and breathable potting soil. If you have root-promoting water at home, you can pour some diluted root-promoting water, which will quickly restore the plant's growth.
Severe soil compaction
Many new flower enthusiasts do not pay attention to the use of potting soil, thinking that as long as they plant the flowers in the soil, they will grow. Therefore, they use ordinary garden soil to plant flowers, which leads to soil compaction in a short time and the entire potting soil solidifies into a hard mass.
It is difficult for flowers to grow well in such soil. If you use this soil to grow flowers or have not repotted for a long time, and the potting soil has compacted, you can take advantage of the spring season to repot and change the soil.
When potting or repotting flowers, use more soil rich in humus, such as pine needle soil, decomposed leaf soil, or self-made potting soil. This kind of soil is loose and fertile, and flowers can grow vigorously without much fertilization.

White substances on the surface of the potting soil
Most of the flowers we grow at home prefer slightly acidic soil. However, over time, the nutrients in the potting soil become increasingly scarce, and the soil gradually changes from slightly acidic to alkaline.
Alkaline soil often shows a layer of white powder on the surface. Once this occurs on the surface of the potting soil, it indicates that the soil has become alkaline, which is not conducive to the growth of flowers. Only by repotting with new soil can the plant recover its vigorous growth.
Many flowers prefer acidic soil, such as gardenia, jasmine, azalea, camellia, osmanthus, kumquat, and Chinese roses. To prevent soil alkalization, in addition to using loose and fertile soil, you can also apply fermented organic fertilizers or dilute ferrous sulfate or chelated iron fertilizers regularly, which can improve the soil quality and make the flowers grow stronger.
Roots growing out of the pot
If you do not repot the flowers for a long time, it will seriously affect the normal growth of the plant. Many flowers have roots that "eat the soil," especially some herbaceous flowers. If not repotted for a year or two, you will find that the potting soil becomes very little, and the roots grow into a tangled mass, mostly old and weak roots with poor absorption ability and insufficient potting soil to absorb nutrients.
When the potting soil is missing in many pots, the roots will slowly grow outward, some out of the pot surface, and some out of the drainage holes. Once this situation occurs, it is also a signal to repot.
If flowers show the above situations, it is necessary to repot them during the spring and autumn seasons when the temperature is suitable, trim the tangled roots, and then repot them with loose and fertile potting soil to help them recover their vigorous growth and produce more buds and flowers.
