Zygo needs help
Not sure what to do with 2 of my Zygopetalum,which have accidentally been left in the sun one day and promptly turned most of their leaves black - or, was it the temperature dipping to 50 deg. that night that caused the damage.
One plant should be re-potted, as it has 5 back bulbs, along with the black leaves on 2 new growths. Only one new growth is green and healthy. How many back bulbs should I transfer into the new pot and, to improve the look, should I cut off the black leaves?
Thank you for your advise.
