We planted three 15 foot himalayan birch trees on Thursday. They came from the nursery with metal baskets around their roots. My eager husband planted them without me. He took off the baskets and all the material fell away. Only the bare roots were left to be planted. Now their leaves are starting to droop and look crispy. I am looking for anything I can do to improve their chance of survival. How much to water them? Root hormone or transplant fertilizer? Should I mist them? Stake them? Read them poems? Help!
