Can anyone tell me what type of pine this is?

    Bill,

     

    One of the first things to look for when IDing pines is the number of needles in each bundle: it should be 2, 3 or 5.

     

    There is a tree key at the NHM. Here's a link that dives in at the start of the pines

    - http://www.nhm.ac.uk/nature-online/british-natural-history/urban-tree-survey/identify-trees/tree-key/#tree-s1-1-12-23-25-30

    Unfortunately, it doesn't get much further than 2/3/5-needled pines.

     

    There are other keys online, which may get you further. But bear in mind:

    - most ID keys do not cater for all species

    - as a garden plant, it is quite possible yours is a particular cultivar of a species (hence less likely to be covered by an ID key)

    Therefore you may not find an exact match.

    And even if you do, it may be wrong. That's because some of the species omitted in the key may be identical in terms of the characters you would have looked at getting that far (they would be distinguishable by other characters).

    Therefore, if you think you have found a match, I suggest you treat it as a possible ID, not a certain one.

     

    ...And you hoped it was going to be easy?!

    Sorry to disappoint you!

        Bill,

         

        That looks like a Cordyline to the left. If that survives, the pine probably will too.

        If the climate is not completely to its liking, it may survive but be a bit stunted.

        If it does well, though, you could indeed have planted it too close to the house (considering shading, root infiltration of drains, etc.)

         

        It is not easy to be successful with moving pines once past the seedling stage. They suffer from premature root curtailment in pots, which can lead to weak root structure, leading to the tree blowing down in a storm. They also generally don't like root disturbance, so you'd have to dig a big hole and carefully extricate a large ball of soil round the root. When replanting, stake it well but only up to half-way up the trunk (that allows a bit of flex in the wind, which the tree needs to react to in order to develop strength in its trunk and the top of the roots.

         

        Not an easy situation. You could take a lot of effort moving it, and still lose it.

        I'd leave it where it is and see how it goes. If it gets to be a nuisance, you can prune the top in various ways (taking the top off, raising the crown, topiary...)

         

        Good luck.

        Mike
