Hi, I planted 6 Osmanthus burkwoodii plants in tall pots last summer as a 'neighbour screen'. They were growing well and seemed healthy. Over winter (Swiss Winter) they were brought into the garage where it is light and around 4°C (give or take). I watered them occassionally and may have left it a week too long in between watering them, though I don't feel it was too drastic!? But the problem now is that they have dropped most of their leaves and do not know why. The leaves are all green and you can see new leaves or possibly flower shoots appearing (I believe the latter). I do not have a clue what could possibly be worong with them all. They look so healthy BUT they're dropping their leaves and they are meant to be evergreens. I am worried that I am NOT going to have my 'screen' come summer when they go back outside to their usual positions. Does anyone know what this problem could be and what I should do or is this a normal phase???
