Hi, I need some advise about miniture conifer trees please.

The 3 foot one should be ok to move, and you can have a bash with the others if you want, but try to make sure you keep an intact root ball and don't break any roots. I'd do it mid October I think, when the plants are fairly dormant.

That is the snag with miniature conifers - eventually they grow into small trees and then big trees. I agree with the advice Bamboo has given you but wonder if you wouldn't be better off removing them and starting again. A 7ft conifer is going to have a considerable size of a root ball and, assuming it survives, will just keep on growing.

Out of interest which conifers are they Linda2?

There are such things as miniature conifers and those that grow about 1inch (3cms) per year are classed in this category. The majority of those sold in garden centers should be classed as slow growing, and this is just another example of miss information given to the general public about garden conifers

I agree Bluespruce - if anyone is considering buying a 'miniature' conifer check thoroughly first as to how big it will grow over time.

Spot on! Moon grower.
