Question
QUESTION: I have a small christmas tree in a pot, which needs repotting into a larger one, what kind of soil should I use please?

ANSWER: Hi Philippa, Take a look at the soil in the container.  You want to match the soil type it is currently growing in.  Is it a bark based soil or a peat based soil?  Then purchase or make a soil of similar consistency.  
Are you sure it needs to be re-potted?  If you can easily push your finger into the soil, it probably doesn't need it.  Jim

QUESTION: The soil just looks like ordinary earth.  This is a christmas tree that I bought at christmas in a pot - could it be that this was a dug up tree, shoved in a pot and the root might have been damaged?  I have put it in a slightly bigger pot, but it certainly does not seem to have much root at all, so I think that might be the cause.  It is still going brown.

Many thanks for your help.


Answer
It's possible.  Many plants are field grown and then dug and potted.  But plants used as Christmas trees seldom survive.  You cannot keep an outdoor plant indoors for more than 3 days.  Longer than that, and the buds start to swell from the heat inside.  The plant thinks it's spring.  Then it is damaged when moved outside.  You usually don't see the damage until late spring when the temperatures begin to rise.  Jim
