Spring Care Methods for the Fleshy Roots of Clivia

As the saying goes, to grow orchids you must first grow the roots. Spring is the season of vigorous growth for Clivia, but improper water and fertilizer management can easily lead to root rot. The main reasons are as follows.

First, overwatering. Whether they are small seedlings or large plants, water must not be applied in excess. When there is too much water, the temperature rises, and ventilation is poor, Clivia will definitely suffer root rot.

Second, the soil is too raw. Whether using leaf mold or pine needle soil, the potting mix must be fully fermented. If some raw soil is put into the pot, under high temperature conditions, this raw soil will ferment and generate high heat, scorching the fleshy roots.

Third, the fertilizer has not been fermented well. Water-soluble fertilizer applied to Clivia must be fully fermented first. If some raw fertilizer is applied to the potting soil, it will also generate high heat and scorch the fleshy roots.

Fourth, excessive fertilizer application leads to root rot. Try not to use chemical fertilizers, 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 can easily cause shrinkage and root rot.

Fifth, improper use of pots. Porcelain pots and plastic pots with very poor air permeability smother and rot the roots and stems when used to grow Clivia due to poor ventilation.

Sixth, 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 heated brick beds or radiators for a long time, and as a result the seedlings quickly smother and their roots rot.

Based on the above situations, we should take targeted preventive measures, such as appropriately adding charcoal and coarse sand to the soil mix and strengthening ventilation, and Clivia root rot can definitely be avoided. But if by any chance you find that Clivia has already developed root rot, there is no need to worry. Just take the plant out of the pot, cut off the rotted roots, apply charcoal or soot to the cuts, then replace the soil and repot it. If the fleshy roots have all rotted away, it still does not matter. As long as the pseudobulb is intact, it has not been sentenced to death. You can pinch off all the rotted roots, then wash the root stem with clean water, and place it in coarse sand to encourage rooting. Within a few months new roots will grow, and then you can move it into a pot for normal cultivation.
