Well i got the Aussie Gold mix in today,and started to repot my orchids in it right away.The seedlings from ebay actually looked pretty good

i had 4 of them that ive had for a month, all 4 had nice roots and growing a new leaf,Bad news is the 2 biggest phals i have,not from ebay, although the leafs looked great the roots were really bad mostly rotted,not by me though.but by the time i got done triming the rotten dead roots, i did have a few good roots maybe 2 or 3 thick ones each.So my question is should i do anything special for these 2 plants

i have all my phals outside under a covered east porch.
