Change culling distance in the view port

Hello All!

I am working on a 16km squared landscape. I am placing trees, grass, rocks flowers and everything you can think of on the terrain. However, I have to be zoomed in a massive amount to even see the objects I am placing because the view port culling distance is really close to the ground. I’ve changed the culling distance on the actual foliage objects themselves, but it doesn’t change the distance in the view port.

How would I go about changing the view port culling distance so I can see all of the foliage in a 1km radius?

Thank you!
