| Can you post a pic of your plants? It takes a long time for a phal to turn yellow leaves from underwatering. Before that phase they will start to loose turgor - wrinkle and turn limp though still green. Underwatering is always preferable to overwatering on a phal IMHO. You need to depot your phals and inspect the root systems - even if you just put them back in the same pots for awhile afterwards. Inspect the roots for any soft, mushy, black, dried, etc. They should be fat and plump. If the root system is poor/nearly gone the plants will appear to be underwatered even if you water them plenty. "Soft" bark indicates the media is breaking down and should probably be replaced. Good bark will retain moisture but is also quite firm and provides good air spaces between pieces so that the roots can breath through the media.
You mention "pruning" - the only thing that is ever pruned on a phal is the flower spike - and no matter where you cut the spike it should not affect your overall plant health, so this makes me question if you have a phal or not? Hence - pics would be good!  |
