From a shallow four inch to eight inch deeper....... To big ?
Is that an African Gardenia (Mitriostigma axillare)?
If so aren't they slow growers?
Looks too large to me. I would be very careful to not over water.
It'll be okay in the Summer. But generally I would go from 4 > 6 > 8 : )
Instead of thinking of "pot is too big" and "overwater," think "mix is too muddy." If it is porous, well-drained, pot size should be irrelevant. I would use this mix, from what I can tell of it from a pic.
Hoping everyone is well and too Pots....Pot as big as you would like as long as the mix allows you to and if you have the room:-)
Very nice looking plant by the way.
Potsalot.......What does your mix consist of? It looks like a very well made 5.1.1 mix of some sort.
Did you make that on your own? Is the majority of that mix bark, because it looks like it?
It looks awesome.
Up sized potting question becomes an exchange of magic mix ideas.
Even better can it stay in that pot for the winter with out sending root though the bottom ?
