When I water my orchids that are in s/h, should I flush them with plain water before the fertilized water? I just recently switched my paphs and they are now ready to be watered. Thanks.
In my experience, it adds nothing to flush first - it probably wouldn't hurt either, but my standard recommendation is to use a fertilizer solution at 100-150 ppm N at EVERY watering. Fill the pot rapidly to the top and let it drain.
