How to prevent and cure the phenomenon of rotten roots in potted flowers? Disinfection methods of flower culture soil

1, watering should be moderate, not too frequent, this is a mistake that many beginners often make. The principle of seeing dry and wet should be mastered. Special attention should be paid to this in the dormancy period of pot plants and in the early stage of pot replacement.

2. All kinds of organic matter mixed in the culture soil, such as rotting soil, manure, sawdust, farm manure, manure, organic garbage, etc., must be fully fermented and decomposed for a long time before they can be used. Do not use raw fertilizer. Otherwise, when the raw fertilizer is fermented, the temperature is too high, which will lead to the root burning.

3. When topdressing potted plants, the dosage and concentration must not be too large, and the principle of a small number of times should be followed as much as possible. If the dosage is too large, the roots will be burned.

4, to ensure that the basin soil seepage is good. When potted flowers are watered, water accumulates on the surface of the pot soil and is not easy to seep for a long time. There are several reasons for this:

(1) The newly installed pot soil is clayey and does not contain organic matter or fine sand, so it is difficult to penetrate.

(2) The tiles on the bottom of the flowerpot block the holes, or the gravel layer on the bottom of the pot is too thin, or the gravel drainage layer is not padded, resulting in poor water seepage.

(3) The potted flowers have not been changed for many years, and the roots are covered in the pots, so that it is difficult for water to seep.
