Aha! Words of wisdom from a professional, Jalandar, in India. Quote:
Hello Jalandar,
What is the reason for removing the plant form the pot and letting it sit for a month or two after pruning?
Thanks,
Jalandar:
"when the root reach the bottom of the pot, it starts to recoil. After some time when there is no space for the root to grow it starts blocking the drain holes in the pot, thus preventing the water to drain. While removing the plant there will be micro injuries to the roots
If you pot immediately and start pouring water, the plant will start to rot from the bottom.
The other reason is forcing the plant to flower .
When you want to prepare for a exhibition take your plant out , sit out for a month, re pot, bingo 60 to 90 days the plant in full bloom without any leaves.

Of course, you do not --have to-- repot when pruning.
