Hi there, we moved house last October, only about 2 miles, bringing with us 2 large box plants which we dug up and put in pots. After a month we planted them out, next to a box of a similar size that was already there. All 3 were fine through the winter and into early Spring, nice and green and healthy looking. However as soon as the growing season really got going, first our box, then the 'resident' one, turned yellow/brown and died. We watered them, but no luck. They were planted about a metre and a half from a large conifer-type tree, but the one already there was obviously coping with the soil condition. What went wrong? The area is a prominent one next to our gate and we would like to plant again (not necessarily box) but don't want to lose more plants.
Thanks for any help.
