should i fertilize my christmas cactus while it is blooming

I've been thinking about that as well, and I'm not sure if you should fertilize your Christmas cactus while it's blooming. The main reason is that you want to protect those delicate flowers and not overdo it with nutrients. However, I think it would be okay to give it a light feeding every so often. Just make sure not to go too heavy on the fertilizer and wait until the flowers start to fade before giving it another dose.
