Key points for preventing root rot in clivia in spring and methods for preventing and treating edible mushroom diseases

Spring is the season of vigorous growth for clivia, but due to improper water and fertilizer management, root rot very easily occurs. The main causes are as follows.

1. Overwatering

Whether they are small seedlings or large plants, water must not be applied in excess. When there is too much water, the temperature is high, and ventilation is poor, clivia will definitely develop root rot.

2. The soil is too raw

Whether using leaf mold soil, horse manure soil, or peat soil to prepare nutrient soil, it must be fully fermented. If some raw soil is put into the pot, under high-temperature conditions, after this raw soil ferments it will generate high temperatures and scorch the fleshy roots.

3. The fertilizer was not well fermented

When applying soybean cake, hemp seeds, fishy water, and so on to clivia, they must all be fully fermented first. If some raw fertilizer is applied to the potting soil, it will also generate high temperatures and scorch the fleshy roots.

4. Excessive fertilizer application causes root rot

In particular, chemical fertilizers must not be applied in excess, because chemical fertilizers are too harsh. Although they can promote rapid leaf growth in the short term, excessive fertilization damages the fleshy roots too much and very easily causes shrinkage and root rot.

5. Using porcelain pots or plastic pots with very poor air permeability to grow clivia causes the roots and stems to be smothered and rot due to poor air permeability.

6. The temperature is too high

Especially during the seedling stage, keeping the bottom temperature at 22°C is sufficient, but some people leave seedling pots and boxes on a heated kang or radiator for a long time, and as a result the seedlings quickly have their roots smothered and rotted.

Based on the above situations, if we take targeted care to prevent them, clivia root rot can be avoided.

But if by any chance you are not careful and find that clivia has already developed root rot, there is no need to worry. Just knock the plant out of the pot, cut off the rotted roots, apply wood charcoal or soot to the cut surfaces, then replace the soil and repot it. If the fleshy roots have all rotted away, it does not matter either. You can pinch off all the rotted roots, then wash the root stems clean with clear water, and then place them in coarse sand to encourage rooting. Part of the leaves should be cut off.
