Ok, now my zygo's blooms are gone (more than one month after receiving it already in bloom) and spike cut. Initially I thought since it's Fall now and almost all other plants I grow are gradually ceasing growth, may be waiting until next spring to repot the zygo is the way to go... However after double checking the plant, I saw that the plastic pot is actually not 4" but in 3x3 size (square) and the plant (above the medium) looks quite oversized in the tiny pot (I know it's the rootball that should match the pot size). I survey available pots I have: one 6x6 (square) metal orchid pot, two 6" cray pots with slits on side, and several regular 4" cray pots. I am pretty sure the 6x6 is too big. In my heart, I would like to use the 6" slit cray pot, but know that it still is two size bigger than the original pot. So maybe repot it with a 4" cray pot now? or keep waiting until spring? (I see the medium the zygo came with is Rexius Orchid barks (informed/confirmed by the grower).
Appreciate your advice.
