I am living in Melbourne on South East coast of Australia and I'm wondering when the best time to plant the cuttings of English box which have sprouted roots about 8 weeks ago. They are currently in a greenhouse doing very well but I'm wondering whether I should leave them in pots or plant them out soon. It is currently early winter here. Days are usually 15 degrees Celsius which is about 59 Fahrenheit.
I can't wait to start my little hedge border and have about 60 of these to plant out. I just don't want to plant them too early and have them die. I'm trying to upload a picture but have problems doing so. Each cutting is about 4 inches high
edit: Thank you very much, I'll plant them out very soon, then I free up some more room in my greenhouse for more! And yes, I learnt a very hard lesson a few years ago leaving a whole lot of small plants in the greenhouse on a hot day
here is the picture showing the size, I was trying to upload it yesterday
