Orchid potting media begins to decompose and break down every one to two years. The time to repot is determined by growing conditions, watering habits and personal preference.>
Repotting Should be Considered When:
- The potting media stays wet for more than seven days
- Yellowing of the foliage
- The plant outgrows its container
- The roots appear rotten
Repot all orchids at the same time in like potting material. If all your orchids are in fresh new potting media they should require watering about the same, thus making watering easier and more consistent.
