Cambria Orchid - Feeding

[Emma_TB]

Hi,

I was bought a stunning pink/red Cambria orchid for Christmas and it seems to be doing well so far, a couple of new flowers have opened up in the last week and it looks nice and healthy (though this is my first ever orchid, but the leaves look nice and green). I have been watering once a week so far, on a Monday morning, as the potting medium seems to have dried out by then. My question is about food, I have read different things about when to feed. Some people have said every week, some every 2 weeks and some once a month. I know it varies on the season and whether the orchid is in it's dormant period (mine isn't and it's quite a cold winter this year). When should I be adding food? When should I not be? Which is a good food to use?

I will probably have some other questions as my lovely plant progresses!

Thanks

Emma
