Keeping tender tree/shrub in pots over winter
Hello, I hope someone can guide me on how to keep a couple of plants over winter.
I have bought my mother in law an Albizia julibrissin and a Myrtus communis tarentina for Christmas. The original idea was to give them to her early to plant in the autumn (I bought them a while back), but she is having some landscaping done so has asked me to keep them till spring for her.
They are both currently in our annex which is unheated. It does get cold in there but not below freezing. Is this suitable? Also, do either of them need any water during this dormant period?
Many thanks in advance for any ideas.
