Preparing to repot new 'cambria's

[Rowangreen]

Already posted a bit about my orchids here

Thought I know it's not the ideal time of year, I feel I need to get these repotted. All are looking a bit shrivelled on the p.bulbs, two are loose in their pots, and one that was knocked out by my cats turned out to have a tight little mass of roots and moss with few (not too healthy looking) roots coming out into the rest of the pot (bark). I've not had much sucess with orchids in the past, so I don't rate my chances of getting them through the winter if I don't sort out the potting medium. I believe having balls of moss in the middle is bad news as it can lead to root rot due to uneven moisture levels?

I'm trying to get some pictures sorted...

I already have some John Innes orchid compost soaking (mix of bark and peat - what I could get!). I'm off to get some hydrogen peroxide to give the plants a clean. I also have some rooting powder which I thought I'd try diluted with alcohol or putting on just briefly if the roots turn out to be in bad nick (not otherwise).

The plants are all at the end of flowering: finished, couple of flowers, all starting to wither respectively, with the plant in worst condition/got knocked over being the one still with flowers. Guess I'll be cutting the spike off...

I also have some phals which I think have some issues.... but maybe that should be another post!
