Against the "Status Quo"

[Fairorchids]

I actually beg to differ. Salts will migrate across a membrane (= cell wall) from high to low concentration, but it is not an instant migration.

Thus:
Application of fertilizer will still be effective after a heavy watering.
Heavy watering is needed after 3-4 days of no watering.
Done in reverse, you waste a lot of fertilizer, either by watering 2-3 times with fertilizer mix, or by washing away the fertilizer the plants have not taken up yet. We then wash out excess in the next watering (drenching).

I sort of have the proof in my Paphs. Whenever I have had a Paph for 6 months or more, I can see a marked difference in the leaf shape & width, between leaves it had coming in (pointed & narrow), and those it grows under our conditions (blunt & wide).

Likewise, I purchased some 6-8 Phrags from Oct to Feb. All were single growth plants, or plants that had grown only single growths for several years running. All are busting 2-4 vigorous new growths under our conditions.
