I planted a ~10 year old arbutus sapling in early March in Victoria, and am wondering about planting shock in the species. The saplings is around 1.5 ft fall and planted out of a small (20x20 cm) pot. I planted the arbutus in a south facing bed in full sun and was careful not to disturb its roots during transplant (the tree appeared root bound). I have recently noticed that a few of the upper leaves are getting yellow, and seem dry and brittle. Is this normal planting shock or is the site unsuitable (well drained but loamy soil)?
