I got these in the post yesterday morning from a uk nursery on ebay, i repotted in chc instantly as they were potted in mud (I think the courier watered them), i could almost pour it from the pots
Ive used the pots they were in, but the roots nearly fill them so bigger pots are needed
variegated calamondin 2.5 foot high
Mandarin clemantine just over 4 foot high
Rio red grapefruit, just over 4 foot high
They were very wet when i got them, but no sign of any root rot, the company sent them 24hr delivery and said they were dry when sent, they were wilting a bit (probably from being posted) but seem fine now,
The only real fault i can find is 3 lower leaves of the mandarin were pale and even by tonight they are greening up a a bit, and the grapefruit had a tiny catapillar eating the tiny new growth leaves
Im not sure on how much these sort of trees cost the rest of the world, but in the UK its normal for 30 to 60 pounds each, i got them for 18 pounds each plus 15 pounds courier for the 3 so not bad for in the UK
