Oxfordshire, United Kingdom
We have a mature cordelyne which in the ten years we've been here has grown by about 6 ft to a height of about 20 feet, and formed four heads. It's also produced several flower spikes over the past two or three summers. Recently, it has started shedding green -- not faded brown -- leaves at an alarming rate -- about a dozen or more a day. The peak leaves on each of the heads are looking a bit sickly: pale with some dark spots (and difficult to photograph, thus no photo).
Maybe the harsh winter has affected the plant. It is a native of New Zealand where we called the cabbage tree when I was a kid. There it grows wild, and seems to tolerate a wide range of habitats, including cold and frost.
Any advice on how to deal with our shedding cordelyne will be gratefully received -- including reassurance that it's just going through a phase.
