I have a watering technique that seems to result in better looking pseudobulbs. When I water, I place the place the entire orchid
pot in a small plastic tub. (mine are from the olive bar at my local supermarket) I water the orchid and let the pot soak for about
an hour, then I water with my fertilizer water.
This seems to do a couple things. First, the potting medium becomes thoroughly saturated, and secondly, the fertilizer salt as able
to redissolve into the water in the tub. Every now and again I will do the soaking with distilled or rain water to really flush the media
Hope this helps. Good luck!
