How to stop a fir tree from growing in height?

peasant

Some years ago we bought some kind of fir tree (don't know the exact kind) in a pot as a miniature Christmas tree.

After sevaral years of "service" it was decidedly unhappy in its pot so we dug a hole in the garden, plonked it in (without the pot of course) and waited what would happen (if anything).

Well, the tree is absolutely thriving. Every spring it explodes in fresh greenery all round and it has now quadrupled in height and bulk.
It's a joy to see it grow every year, but at the same time we don't want to end up with a massive tree taking over everything.

It's currently at the stage where the last spurt of growth is almost over, the new needles are almost as dark as the ones from previous spurts and the buds for next year's spurt are already forming.

Now ...what I'd like to achieve is the keep the tree alive, keep it growing and getting stouter but not much taller if possible.

Can I just cut off the tip every year?
Will that harm the tree?
If not ...when is the best time to do this ...now or just before next spring?


Any help appreciated

You can cut the tip off, on the understanding that we don't know what sort of tree it is, it won't do any harm. What it will probably do is start to produce two leaders (main shoots pointing upwards), you cut them off and it eventually turns into a sort of one-tree hedge, the shape will be gone.
