VF-11 Question. . .
Hi fellow hoya lovers,
Is it true that leaves take in nutrients from the under-side of the leaves? Is the plant not getting all the benefit if you only spray the top?
My common sense tells me it isn't true, as in the wild the under-side of the leaves probably never even get wet. But then again, perhaps they take in the nutrients when the under-side of the leaves come in contact with whatever they are clinging to. . .
Do those of you that spray with VF-11 pay particular attention to the under-side?
I do with the ones I can get to, but some of the fuller ones, it's nearly impossible.
