growing phrags on windowsills
Tom,
sorry for the delay replying but I've been away. You should persevere with the phrags.
I have a collection of 9-10 phrags growing on a windowsill in the UK and they do Ok - better than most of my paphs.
Like you, my catts seem to be better adapted to the lower humidity of indoors.
I grow the smaller growing moisture loving kinds of phrag and try to keep to the more vigorous hybrids. I use standard bark mixes, repot once a year and keep each pot stood in one cm of rain water all the time. This seems to compensate for the lower humidity.
In summer the pots migrate into a cold greenhouse and spend time amongst the tomatoes.I've just brought all the pots back inside a couple of days ago.
As regards availability, Ratcliffes have some stunning phrags for sale each year, mostly from the EYOF but they tend to be expensive. No-one else in the UK has many. You need to import from some of the german nurseries if you want a good general range,
Regards,
David
