I have 5 Dawn Redwood in a bonsai bowl bought from a commercial garden centre. The label says to water frequently and is suitable for
outdoors. I put them in the garden when we bought them April but the leaves began to go red/brown which the label says is autumn colouring so I brought them back into the conservatory. I live in the North East of England which can be quite cold, even at this time of year. I have fed the trees regularly. I am very much an amateur so would appreciate any advice.
Thanks
