Arborvitaes are very sparse
I bought about 60 trees and planted them, in July of last year, around my pool in the backyard. All but two survived the winter. I was happy! When I bought them they were anywhere from 1' to 5' tall. Some full and some pretty thin/sparse. Even my full ones do not look like what you would buy at the big box stores. I paid I think $1.50 a tree so it wasn't a huge expense and they had a bed they took them out of. They were really jammed in there tight so a lot of them had more growth on the top than at the bottom.
What I would like to know is how can I get these to fill out more? Will they if I just let them or should I trim the tops so the growth goes side to side until they look fuller.
Most of them look something like this:
That is just a picture I found online, I can take pictures when I get home if that would help. But I really want them to look more like this
Keep in mind, those aren't my plants I'm just pointing out how I want mine to look. Would love if someone could hlep me out. Thanks!
