I have two cordilines I grew from seed about 16yrs ago, over the winter the leaves have died off and fallen from the trees. I see that other trees of this genus around here are also in this sorry state and have not seen any healthy plants locally, has anyone any ideas as to what is killing off my best plants? My location is ayrshire on the west coast of scotland

Hi BUFFS. I'm afraid I can't answer the question, but for people more expert than me, can you describe the course of the disease? Fungal? Started at the bottom or the top? Any other info that might prove useful? -
There is one in a garden in our street that died back to ground level in 2010 during a period of very cold weather.
It came back from suckers and is now over 10 feet tall.
They just need a few years to harden off before they can be fully frost proof.

Almost certainly the cold. They're moderately hardy, but prolonged heavy freezes will kill the top growth.
As said above, though, the stump and roots (and often even some of the trunk) usually survive, so they should resprout in the spring.Comment

Also don't be too tidy.
Leave the old dead leaves on until the risk of pipe bursting weather has ended.
They will help to protect the growing tip where the wood will be less hardened.
