Is it mulched?

Yes, have a couple inches of mulch around it.

Mulch is typically all that you need. Stakes might be useful in windy location with tall specimens or transplanted shrubs/trees. I have never used stakes wuth 1, 3 and 5g pots though.

Well, the stakes wouldn't be for support (sounds like that's what you're saying, Luis). They would just be something to wrap the burlap around to create a wind barrier, for a measure of protection against drying winds.

Wind protection sounds like a good idea for a new-in-the-ground plant of any kind. Actually, if you can come up with a more permanent wind-break, your plant will be at less risk of drying out, a situation that camellias do not appreciate. Wind-breaks also mitigate temperature extremes.

Good luck,
