What to Do About Root Rot in Cuban Oregano? Causes and Solutions
1. Mild root rot
Soil that is too moist easily leads to root rot. Watering too much at ordinary times, or failing to protect it from rain or drain water in time during the rainy season, causing water to accumulate in the soil, can both lead to root rot. In addition, improper fertilizing can also cause root rot. If the root rot is not serious, first try to save it:
Take the Cuban oregano out of the potting soil, clean all the soil off around the roots, then prepare a pair of disinfected scissors, cut away the rotted roots, then disinfect the roots with potassium permanganate, and plant it in clean, loose soil. After some time it will grow new roots.
2. Severe root rot
If a large number of roots have all rotted away, the situation is more serious, and you can only re-propagate by cuttings:
1. First cut off its stems; there is no limit on length. Then remove all the leaves from the lower part of the stems used for re-propagating, leaving only 2-3 leaves at the top, then place them in a ventilated spot to dry for 1-2 days, so they will not rot again after being planted.
2. Insert the dried stems into suitable soil, then place them in a cool, ventilated spot. You can also simply care for them like a healthy Cuban oregano. After a few days its leaves will recover, and before long it will grow roots. Do not water it excessively; it can be given a bit more sunlight as appropriate.
