What do I need to use to transplant an orchid to larger planter:)

You will find out all you need to know on this website:

A. bigger pot with good drainage/aeration.
B. Orchid bark (usually fir bark) or perhaps tree fern
C. take off old pot
D. remove old media from roots
E. Rinse
F. put roots into new pot, holding plant above the media line
G. fill in bark/medium around the roots
H. Shake/compact down the medium to fill in between the roots

To remove the orchid from the old pot, turn the plant and pot sideways, and gently ease the plant out of the old pot, supporting the plant with one hand and the root ball with the other hand. Place the root ball into the new pot and turn the plant upright. Add more bark around the root ball until it's at the same level as it was when the orchid was in the old pot.
Soak the new potting material. To do this, use a bucket or something the plant can sit in and be swamped. Pour water into the bark until it just starts to float (the water level in the bucket or whatever gets high enough to float the bark).
