Clivia was placed in the sand, and Reagan was 3 cm long and moved to the original soil. What if Reagan is rotten again?

There are many reasons for root rot of Clivia, but they are mainly caused by high temperature, excessive watering, application of concentrated fertilizer or raw fertilizer, and cultivation of soil-borne bacteria. Generally speaking, there are two kinds of rotten roots: first, most roots are still good, and only some are rotten; Second, most or all of the roots are rotten.

In the former case, the rescue method is to knock the rotten root out of the pot immediately after finding it, remove the attached soil, rinse the root system with clean water, then cut off the rotten root with a clean blade, and then smear the rotten root with 0. 1% potassium permanganate solution (or smear charcoal powder, soot, etc. ). After drying in the shade for half a day, plant it in sterilized pine needle rotten soil or fully decomposed sawdust or mountain mud basin. After planting, put a transparent plastic bag on it and put it in a semi-shady place, and water it less to keep the soil slightly moist. At the same time, spray 0.2% potassium dihydrogen phosphate aqueous solution on leaves every 5~7 days to increase nutrients and promote their rooting. In this way, new roots can grow in two weeks. At this time, take off the bagging and gradually transition to normal maintenance.

In the latter case, the rescue method is as follows: firstly, wash the stem base with water, then cut off the rotten part horizontally with a sharp knife (the incision should be smooth), then apply sulfur powder or charcoal powder on the incision to prevent wound infection, put it in a cool and ventilated place, plant it in a plain sand basin after the surface of the incision is slightly dry, water it once two days later, and then keep the basin soil moderately moist to avoid fertilization. At the temperature of 20~25℃, new roots grow around the incision after about 10 days, and can be transplanted into a new culture soil basin after 50 days, and gradually transferred to normal maintenance.
