Abandoned orchid

[Chantelle]

Hi Im Chantelle,

Iv recently moved to east london in south africa,
When i moved in here about 5-6 months ago i found an abandoned orchid in my yard! At first i thought, that could never be and orchid because it would surely be dead if it was since the house had been empty for AGES, but i nurtured it non the less just in case! Well it seems pretty happy now and i think it is a dendrobium orchid, i will have to take a pic and post it on the identification forum.

My biggest concern is the medium in which it is growing and to add to that, there is portulacca growing in the pot with it! I dont want to transplant it as i am afraid i will kill it! alot of the roots are above the soil medium and i have noticed a peice of orchid (almost like a cutting) which has been left in the pot which has put down roots and grown leaves!!!

What should i do? maybe take the little peice and plant it in the correct medium once i have identified it and leave the bigger plant in the pot that it seems happy in?

please help me take care of this poor thing!
