What to do if orchid seedlings rot in summer (orchids should be ventilated during the rainy season to avoid rot)

First, the treatment of seedling rot caused by orchid root damage

If the tips of the leaves of new seedlings are burnt or turn yellow, it means that the roots of the orchid in the pot are damaged. The main reasons are: the planting material is compacted and not breathable, the root breathing is blocked due to lack of oxygen, the air circulation is poor, and the water supply is improper .

When encountering rotten seedlings in this situation, it is necessary to repot in time, remove the diseased area, sterilize and disinfect, dry the wound, use new planting material to replant, control the moisture, increase environmental ventilation, and keep the planting material slightly moist and dry.

Secondly, the treatment of physical damage to orchid seedlings

   Due to the blockage of leaf veins caused by excessive pressure on the leaves, the compressed parts of the leaves will gradually turn yellow; the leaf tips cannot recover after being broken, and the creases are too deep to resume growth; the leaves are torn from the middle starting from the tip, etc.

The emergence of these problems is all physical damage to the orchid seedlings. Once discovered, the local damage should be pruned immediately. Or the position of the orchid pot should be changed to make the space for the orchid seedlings to grow sparse to avoid further damage .

Again, rotten seedlings caused by poor cultivation management

   For example, if the outer bracts of an orchid seedling turn yellow and fall off, an orchid lover with a little cultivation experience can tell at a glance that the cultivation method is wrong.

Generally speaking, the incomplete outer bracts of orchid seedlings reflect that the planting material in the orchid pot is buried too shallowly, or the planting material on the pot surface is too coarse, or there is insufficient water supply in the pot, or at least the upper half of the planting material surface is too dry, and the roots are shriveled due to the influence of drought.

The treatment of this phenomenon is not restricted by time or season. Just identify the problem and deal with it in a timely manner.

In short, to avoid the phenomenon of new orchid seedlings rotting in summer, more attention should be paid in daily maintenance and management.

Environmental ventilation, plant material ventilation and drainage, orchid cultivation methods, and orchid pot placement should all be checked in a timely manner , and any problems found should be dealt with immediately. This will help reduce the incidence of summer seedling rot.
