Citrus trees sold as ornamentals/houseplants in 1-gal pots are typically small-leafed with correspondingly thin branches, looking much like small bushes. Given the proper conditions they grow to much greater size and bear little resemblance to their original form. (Not surprising since they are trees.) So could it be that these ornamentals are treated with a growth inhibitor to maintain their small size? It occurred to me that this may be a possibility since poinsettias are so treated to make them short and bushy. [Question cross-posted to another forum.]
