I would take it outside during the growing season and bring it inside during winter. If your mild winters allow the containers to be left outside year around without cracking then that is another option. See the American Camellia Society link below for more info on container grown camellias.

Luis, what's "cracking"?

Some materials used to make pots/containers are not cold hardy and will crack if it gets too cold. Terra cota can crack if left outside during winter, for example. The materials expand when wet, freeze below 32F and then can crack.

My understanding is that camellias don't make good houseplants, although I have heard of camellias doing well in unheated rooms/porches that get some sunlight.

If your plant has been outside and doing well there and is now setting buds, my feeling is "if it ain't broke, don't fix it". If you get a forecast for freezing temps, you may want to bring it inside temporarily.

I don't know what's in your 5-1-1 mixture, but I wonder if a fast-draining soil is really appropriate for a dry climate like yours. It's true that camellias don't like wet feet, but they do like a moist- not wet- soil. If you were to add some compost or other organic material that retains moisture, you might be able to water and feed your camellias less frequently? Just a thought...
