First of all: yes, you should wait until your orchid is done blooming to repot. And while we can’t know for sure without seeing the orchid in question, our best guess is that this owner’s plant has air roots.
Repotting an orchid while it is in bloom is something that many new and experienced orchid owners may have to do at one point for a plant. Unfortunately orchids are vastly different from many other plants and repotting an orchid while it is in bloom can lead to a world of problems. So when should you repot an orchid when it is in bloom?
When to repot your orchids?
You should plan to repot your orchids every one to two years even if everything seems fine. However, you should repot sooner if you notice that your orchid’s container has become too small, the growing medium has broken down more quickly than expected, or your orchid’s roots are becoming pot-bound.
When I was researching we ran into the query “How do you care for orchids after they bloom?”.
Return to your regular watering and fertilizing schedule. There is no concrete rule on watering orchids, and it’s very easy to over-water the plants. The American Orchid Society recommends only watering when the soil has dried out. Water by placing your plant in the sink and running the water for about a minute. You should fertilize your orchid about every 2 weeks.
How to repot an orchid step by step guide?
Step by step. 1 Remove your orchid from its pot, untangle the roots and remove all the compost. Shorten roots to 15cm and cut off dead or diseased pieces. Leave aerial roots (growing outside the pot) intact. 2 If the roots fit back into the old pot, then reuse that, as sizing up can leave seeds sitting. In wet compost for too long.
