....or below, as the case may be!

you have our permission.. to do whatever you want to the plants in your garden ... what more can i say???

i dont know what else you need to know.. get saw .. apply to bark.. and continue back and forth motion.. until the top is severed ...

it will not kill it ...

who knows what it will look like in 10 years ... no one has that answer ...

worse thing you can do.. is make it so ugly.. you actually decide to remove it some time ...

personally.. i wouldnt do it.. but who cares what i think about your tree ...

perhaps a picture will get you alternatives ...

have fun.. teach it a lesson on who is in charge of this house..

No, no, no and no!! Topping trees of any kind is not an acceptable practice. Sometimes selective and judicious pruning can be used to restrain the size on certain species but in general, a tree growing too large for its location should just be removed.

Here is a link that might be useful: Stop topping!

When a conifer such as this has out grown its assigned place to grow it's time to remove and start over.

I have a Hinoki Cypress growing next to the support beam near my front door entrance-way......the top two feet of the Hinoki were knoocked off by a clumsy idiot I had (mistakenly) hired for an ice and snow removal job on the gutters and roof a couple of winters ago..
Well the Hinoki has recovered and one would never know it had been "topped". I also trimmed some of the branches to contain its sideways growth and it looks A OK.
So its my belief that one can control this type of evergreen pretty well. Certainly I do not want mine to grow beyond gutter height and intend to trim it from time to time.
