Phal - issues with fertilizer, pots, and environment, mainly - just issues...

[bil]

As said, everyone has their own way.

I like to repot immediately on purchase. I have little faith that they will be properly potted.

I pot them up in coarse bark (2") that has been sieved to remove the fine stuff, and I use a wide, shallow pot. (Remember if you use coarse bark you cannot overpot.
I don't soak it but pot it dry and leave for 2 days to let any breakages heal.

When I water I use RO water with the bare minimum of fertiliser in every watering (Go to 'first Ray's ' page and read all the fertiliser stuff). Basically fertiliser is the least of your worries (unless you use to much), and frankly almost any fertiliser will do as long as it is a very weak solution.

I spray the media till water runs out the bottom. I do that once a week in winter, three times in summer.
