Hello, all: I have a Hick's yew in my backyard and am building a new garden
box to hold three or four more. I'm not describing this very well, but
what I need to know is how deep a Hick's yew's roots will go. The one I
have right now is about 6-7 feet tall and ideally I'd like the new ones to
grow to the same height, but I need to know how much room to leave for the
roots.

Any information will be gratefully received!

Hi David,
The major concern would be the spacing. They will grow to 6' to 8' wide or more, so space them accordingly.

I'd say to make the boxes at least 3' deep or more.

Many thanks! I looked everywhere on the internet and in the few gardening
books I had, but it's a very specific question. I'm grateful for your
expertise!

David, you are very welcome. I meant to tell you that yews have extensive root systems when they mature, so try and make your box without a bottom so the roots can grow into the native soil.
