Hi friends, I’m in a dilemma as we have 40+ year old cedar trees so tall that the bottoms are bare - where we would like add some privacy below them. I’m wondering if planting new cedars below the others will stick/even work with the roots? We would have room to create a 1 or 2 foot deep bed for them, just not sure if that’s the fix. Otherwise we’ll have to go the fence route which we all know can be pricy. appreciate any advice on this, thank you!
