I found a better size box for this plant at uhaul. It is $8 and is 15x15x48. I can adjust it down to about 30” to what dimensions you are willing to pay for shipping. I also have a 15x16x27in Home Depot box that is around $30 to FL, just know that I will have to obviously chop this plant down a lot but it is a tough plant that will recover very well. Go to
https://www.pirateship.com/rates and put in 27295 zip code for mine, dimensions and 30lb weight and see what the UPS Ground reduced shipping rate is on there. You will find 10lb to 40lb is all the same as it is rated by dimensions. Also it jumps drastically in price from around 42” to 46” at least to FL from here. If interested let me know.
