When is the best time to change orchids?

The best time for orchids to change pots should be at the vernal equinox or autumnal equinox, and the north should be after the vernal equinox or before the autumnal equinox. Because of the differences in climate in different regions, we can also master it according to the temperature. Generally, the low temperature is above 10℃ and the high temperature is below 30℃, which is the suitable temperature for normal pot changing. Here, Uncle Gardener introduces the best time to change orchids.

1. After two or three years of potted orchids, because the nutrition of plant materials has been exhausted, it can not meet the needs of the continuous development of orchid seedlings, and orchid seedlings look thin and short.

2. After years of sunshine and rain, the structure of orchid mud has changed, and the planting materials have become hard, which has affected the ventilation and water supply.

3. Blue seedlings are overgrown with weeds and intertwined, and there is no room for new seedlings and new roots to continue to develop, which also affects the normal growth environment of old seedlings.

4. Plant materials are infected by bacteria, fungi or viruses, which brings survival crisis to orchid plants.
