I live in France and when we moved in 7 years ago very cold weather turned my lovely mimosa tree black overnight. I was advised to cut it back to the floor which I did and now have masses of 8ft high mimosa shoots which have sprung from the roots and form a mass of yellow flowers. I have had to cut it back to the ground twice since the first time and it never seems to suffer.


I too have a 4 year old mimosa which DOES seem to have suffered from the extreme cold. Previously it has coped being slightly frost burned, but now the whole top of the plant has gone brown and brittle and I am wondering if it is worth trying to cut right back in the hope that some life is still left somewhere! the plant is quite substantial (6' tall, girth 10" or so). any advice welcome.


my mimosa is inthe garden protected from easterly winds.It seems to have survived the severe recent rosts and snow.It is about 4or 5 years old and inclined to bend.Currently I stake and tie it.Will it grow more upright if I prune it, and is this advisable, if so when is the best time?


Mimosa is an infestant in Portugal ! see the link
