Causes and prevention of root rot in clivia, with methods for controlling edible fungus diseases
Spring is the season when clivia grows vigorously, but due to improper water and fertilizer management, root rot can easily occur. The main causes are as follows.
First, overwatering
Whether they are small seedlings or large plants, water must not be applied excessively. When there is too much water, the temperature is high, and ventilation is poor, clivia will definitely develop root rot.
Second, 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, this raw soil will generate high temperatures after fermentation and burn the fleshy roots.
Third, the fertilizer is not well fermented
When applying soybean cake, hemp seed, fishy water, etc. 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 burn the fleshy roots;
Fourth, excessive fertilization leads to root rot
In particular, chemical fertilizers must not be applied excessively, because chemical fertilizers are too irritating. Although they can promote rapid leaf growth in the short term, excessive fertilization damages the fleshy roots too much and can easily cause shrinkage and root rot.
Fifth, using porcelain pots or plastic pots with very poor air permeability to grow clivia
Because air permeability is poor, the roots and stems are smothered and rot.
Sixth, the temperature is too high
Especially during the seedling stage, maintaining a bottom temperature of 22°C is sufficient, but some people leave seedling pots and boxes on heated kang surfaces or radiators for a long time, and as a result quickly smother the seedlings and rot their roots.
Based on the situations above, if we pay targeted attention to prevention, root rot in clivia can be avoided.
But if by any chance you find that clivia has already developed root rot, there is no need to worry. Simply knock the plant out of the pot, cut off the rotten roots, apply charcoal or soot to the cut surfaces, then replace the soil and repot. If the fleshy roots have completely rotted, it does not matter either. You can pinch off all the rotten roots, then wash the roots and stems clean with clear water, and place them in coarse sand to encourage rooting, cutting off part of the leaves.
