Help with valentines day orchid

[xjasminex]

Hello!
I am new and was wondering how to best help my heart shaped orchid that i received for valentines day.

It was bought from wegmans and is actually two orchids in one pot. They are the phal variety. The flowers are now wilting. It is planted in sphagnum moss in a ceramic type pot with a drainage hole and a tray dish underneath.

I have no real experience with orchids other than buying them and trying to keep them alive.

I know that the bark mix is a better substrate, but im not sure when the best tome to replant is....and im not sure what kind of pot would be best either.

I am also unsure of when the best time to fertilize is...

Thanks for your advice!
Jasmine
