I purchase 3 3yr old trees (Washington Orange, Mandarin orange and Key Lime). When I recieved the trees 2 days ago the leaves look healthy and it has been two days now that it has been on the ground and I've noticed the leaves are withering. the leaves are still green. Is this common when the trees are planted to the ground for so many weeks so it can get used to it? What should I do to verify this or any recommendations. This is my first time planting. Thanks in advance.... lostboyca
