Hi. I was given this orchid in april when it was in full bloom and it has been in my office on the window sill. On Fridays when leaving office for the weekend i shift it into a shady corner. It is quite happy and since the flowers fell it has grown two new leaves. Now do i need to repot it in view of the aerial roots? My very first phal died suddenly so i really want to keep this alive and in good shape.
