Unhappy Magnolia Grandiflora: frost damage?
There is a Magnolia Grandiflora in my garden, about 1 metre 60 high (I don't know how old that makes it), which was here when I moved in. It's in a nicely sunny spot, but is currently not looking good.
One or two tiny branches have definitely died, the others are either green, or more usually, brownish or greyish towards the tips. ONe of the buds (the only largish one - about the size of a ping-pong ball) has gone black. The other tiny new buds are a coppery brown colour, as are some of the leaves, a few of which have holes in them.
Looking around this site it seems that this must largely be down to frost damage. Is there anything I can/should do to rescue the tree?
WHen I moved here the magnolia was quite advanced, and I noticed that it didn't produce a lot of flowers. I assumed this was because it was young, but might it just have been unhealthy?
