It gets really hot here too and humid in the summer. My old apartment was facing north so it didn't get too hot, but here it is facing south and on sunny days, it gets really hot. but we've been having rainy/cloudy days a lot lately so they are all alive and the buds are opening up all fine, which is nice.
Regarding their varying degree of vigor, maybe the ones I bought are either genetically vigorous or they had been grown very well in the nursery they came from, or both!
How long have you been growing these??
Do they grow better in the winter for you?
They will stay indoor year around here. the problem with the winter time is that there's not enough day/night temperature difference. The day will be warm and the night will also be warm because I have to be comfortable.
My other orchids all survived the winter indoor fine, so I will have to see how these guys will do, given that they will survive the summer first.
I really wish I knew the names and the parents in their background so I know better and expect what to do.
I just read somewhere that miltoniopsis phalaenopsis is warmth tolerant so if this is part of them, then they should be fine through the summer here. or so I hope.
One of mine has one leaf loaded with little black spots, which I am actually thinking of cutting off tomorrow.
Most other leaves are fine except a few big and small dark spots, which I suspect sunburn. Maybe the growers exposed them to high light to increase flower counts.
then many of the leaves show these subtle lighter green spots everywhere, which I have no idea what they are. hopefully not virus.
These are really beautiful orchids and I just wish I had more space to have more around.
One last thing, about keeping them evenly moist, I find that very difficult. I think I killed my last one by overwatering. All of mine are in plastic pots with slits on the sides. It looks like they are potted in fine grade bark mixed with something else, but they all seem very old.
I soak them in bucket full of water once a week, but mist the roots exposed on top everyday.
so far, all the buds are developing and opening fine, so I guess it's all good for now.
I just accidently damaged and lost some buds and spike while carrying them home.
