One of the best times for repotting orchids is right after they have flowered and you see signs of new growth. Repotting is definitely required when you see the roots of the plant growing over the edge of the pot.

Steps potting orchids:

1. Remove the orchid from its pot. Use your knife if necessary to loosen the roots from the sides and bottom of the pot. Put the plant and soil on newspaper.

2. Using the knife, remove the old potting medium and any dead or decaying roots that you may find.

3. If alot of the roots have been rotted, you will want to repot in a pot of the same size or one size smaller than the original pot. But, if the roots are healthy, and filling the pot, then choose a pot that is one size larger.

4. Place some chunky material, such as broken clay pot-pieces, stones, or styrofoam peanuts in the bottom of the new pot. This will ensure adequate drainage for your orchid.

5. Put the plant in the new pot so that it is at the same level it was in the original pot. Adjust chunky material and add growing medium as needed so any new shoots will be level with the rim.

If your find that most of the roots are on one side of the plant base, place it in the pot with the plant close to the edge so that the roots can continue to grow in their favored direction. If the roots are distributed all around the plant base, place the plant in the middle of the new pot.

6. Add orchid repotting mix to the pot and press firmly in place so that when the pot is full the plant has no wiggle room. Be careful not to damage the roots.

7. Place a stake in the middle of the pot and secure the stems with ties.
