Hi. My Gardenia has been in the same pot/soil since 1995. Roots are not growing from drainage holes, but I'd like to add more soil and/or repot.
It's in a 10" plastic, growing pot. What's the largest pot, an indoor-winter/outdoor-summer-grower can thrive? I'm afraid to repot in too large a container since, so far, cross my fingers, lol, the plant is fine.
Is there anyone here who grows Gardenias indoors in winter, who has their 'denia in a larger than 10" pot? Thanks, Toni
