Most supermarket fertilizers containe Urea.

The best Fertilizer for orchids available in the uk is this Rain mix Orchid Fertiliser, potting compost and orchid supplies- Orchid Accessories

I've had no issues with Miracle Gro across many genera including paphs, phrags, and masdies for the last twenty years. Maybe I'm lucky but I'll keep using it as it's cheap and as you state can be easily picked up from the supermarket and can be used on all the other plants I grow as well.

For the Phalaenopsis, i wait for the media to go dry and roots grey, then give it a soak for a few minutes then drain.

As i say i'm just starting, so have so many mistakes ahead of me yet. I'm probably making a few now.

Sounds like the right approach to me, good luck growing and hopefully it will work for you.

Thanks for the advice. I think i'm going to start off in really low concentrations and go from there. I have a big tub of the stuff that will last me ages as i don't have a large garden at all, so if i can use it here that would be great. I suppose if i flush the root system / medium every now and again might help. I'm getting really good at preventing myself from buying more. The ones that got away.
