Diana: I'm going with the "blame the weather" theories. If the red is not
from sun [you sure, no loss of nearby trees that might have been providing
more shade than you thought?], then it should be temperature which has been
weird and yo-yo-ish for the last several weeks. Up until just a couple
weeks ago, we were cooler than normal (except for a couple of hot spells),
now we're having record highs ...

Here at JBO, we had less leaf loss than usual last Dec-Jan, then they made
up for it in Feb-March. Kenni

Hi, Group,

Lately we've been watching far too many of our Vandaceous plants losing
leaves. The leaves turn yellow and drop. The plants are otherwise healthy,
blooming regularly and bug free. We haven't changed anything; water,
nutrition, location, all the same as usual. And to be precise, it's not
all of the plants. Some are just as full as ever.

Any ideas?

Diana
