Likely 20' in time. The 8-10' may be a 10-15 year estimate.

If you're talking a 'Turn around' in the driveway in front of the house, trees that grow 'up' will eventually block the view of the house.

If you could post some pictures, at different angles, there are people here well versed in design that could give you suggestions and you could go from there. :^)

Thanks for the input. I’ve attached a few photos here. Blocking the view of the house is actually part of the reason I’d like to put trees in, as the house is fairly close to a busy road and has lots of windows. I’d eventually like a slightly more secluded feel, even if it loses a bit of curb appeal.

I also have a large backyard that currently consists of mostly weeds (thanks, precious owner), so I’ll plant any of the trees that don’t fit up front back there

Where are you located? While they are sold all over the country, Colorado blue spruce/Picea pungens are native to dry land areas and will typically get fungal diseases that cause them to lose needles in more humid areas such as areas east of the Mississippi. Even in my cold part of the country, mine have become diseased and will need to be cut down. They are almost exactly 10 years old, and I wasn’t aware of issues with them in my area before I planted them. Here is a recent thread, though specifically for narrower blue spruce, that will give you some alternatives if you live in an area where they are a poor choice for long lived trees.

I’m in a state where they grow natively

No photos of the area?

Uploading through the built in photo function wasn’t working for me

"in conifers... with named varietals .... most estimates are at 10 years... and you can presume.. at 20 years.. they will be twice as big in each dimension ... etc for 30 years ..."

Not a particularly accurate assessment but it does contain an element of truth in that plant tags - doesn't matter if they are conifers or any other woody plants - will typically only give a size estimate at a particular stage of growth. And it's not always 10 years :-) And the plants won't always be double in size for twice as a long a growth period.....otherwise we'd have trees reaching half way to the moon!!

But if you Google images of the tree in question, you will often find examples of mature specimens that will illustrate how tall or full a tree will have the potential to get. The 8-10' width is very much on the conservative side of the picture!

Well, three 'Bakeri' in that area would be a bit much. Two maybe...for a long enough time...and since you've bought them already. Do you have another area of the yard for them?

I agree, two of them @15 ft. apart. That would give you 10 ft. all around for branches which would be plenty with a mature width of 15 ft. Even if the tree would eventually get to 20 ft wide, the branch tips would still be inside the grassy area.

And as long as you have another place for trees in the back, no problem. :-)
