I am looking for a virginia creeper. I have one but the leaves are very large. I am intersted in one with small leaves as it is for a small patio area - preferably a purple colour in summer. Do you have any suggestions as to where I could look on the internet?

The attached pictures show the condition of a plum tree in my garden. Where the branch broke off, the exposed wood is soft. Also, there appears to be wood worm. Can the tree be saved? Can you let me know please. Thanks, Geoff

The bark is coming away in some parts of the plum tree in my garden. In these areas there have been a lot of centipedes living there. Also, where one branch was cut off, there is a bubble of sap coming from the tree. From the attached picture, do you think this is a problem and how might it be corrected?

There is a silver birch tree in my garden which appears to be decaying. please see the attached picture. Do you think that the tree should be cut down or is it possible to save it somehow. Also, if it is a prevalent disease, is it possible to prevent it spreading to other trees? It would be great if you can answer soon as I am concerned that the tree may fall down.
