Mounting/ and vanda questions

[NWBOCHs09]

Hey I'm not too incredibly new around here just read often but lately find myself with a few questions ...

Can you mount a phally to any kind of wood or just certain kinds... I picked up a yellow and purple bloomed phal at lowes tonight for 5$ in great health with new root growth and wanted to mount it to wood...


And... I have three vandas (also lowes) I've had for about a year and a half... They are mounted in a fern bark basket... Which is only 4 inches... Small I know but I'm scared to upgrade them and damage the plant... Anyway... One is red, the other purple and lastly orange.. The orange one I have had to bloom twice during this time period, however my other two have yet to bloom.... I have also had a hard time getting their lighting demands right, but finally think I've got them in a spot they will like... Before I had them were they got morning sun from about 8-11 but they were turning red.... So I moved them slightly back so they are shaded sooner but they remained redish.... I left them there fore several weeks... Still red, so a few days ago I took them and hung them where they receive only a little early morning sun, dappled sun throughout the day till about 3 then sun from 3-4 or so and dappled again. They are already turning green again. I'm also trying to keep them watered more. And fertilizing them now a little heavier with a mix of orchid plus and bloom booster added to distilled water. I spray them with that once a week or so, the rest of the time with distilled water. Any tips with these would help also.


Oh! And lastly... My catleya is producing plenty of new growth but the bulbs are alway striveled... It blooms fine, a beautiful red, but it's bulbs are shriveled... any suggestions here???


Thanks!
