They need to be far enough from the house so they get enough sun on the back side. The foliage will die off otherwise. Roots are not a concern if your foundation is structurally secure/intact.

Thank you! I only have enough room for 1.5ft to 2ft from the house. Is this ok?

I dunno :-) Since I can't see the site and the amount of sun it might receive, it may or may not be sufficient spacing. Since the estimated width of a mature Blue Point spiral is 48 inches, 2 feet would be the very bare minimum.

Thank you! The sunlight is good. I plan on keeping it thin with spiral shape pruning as needed.

You can't keep it any thinner at the base than it is now. It will grow wider although not as wide as if it were left completely unpruned. A mature BP juniper will have a base width of 8 feet or more, whereas the spiral should max out around 4 feet.

FWIW, pruning a juniper - any juniper - beyond where healthy green foliage is present will result in permanent dieback Lack of adequate sunlight will do the same.

I am going to transplant them since they haven't rooted. Currently they are a foot from the house. Going to do around 2 feet because of space. I'm afraid though as it matures it will press on the lavenders up front and may need to transplant the lavenders eventually.

Can you keep a Blue Point Juniper in a large pot? I have a third one and plan on placing it in a pot and leave in the porch.
