Everyone knows that the soil layer in pots with indoor plants needs to be changed periodically.
Over time, the soil becomes poor and even dangerous for flowers.
As a rule, soil replacement is done once every two years. But the procedure can be done earlier.
If you evaluate the top layer of soil in the pot, it should be soft and loose. If you see a "crust" of hard soil, it is better to replace it.
In this case, moisture and nutrients do not reach the roots.
This is the most important indicator that replacing the soil will be a good decision. If the plant looks weak, "sluggish" and lifeless, then replanting will help save it.
If you notice that all the liquid during watering ended up on the saucer, then it is worth transplanting the plant into a new pot. Another signal can be the "peeking" of the root system from the drainage holes.
If these signs are present, it is recommended to transplant as soon as possible.
