I got a great gift this weekend- two tall, full, large-caliper trees for my backyard. They're planted and loving this overcast Sunday, but I was wondering: does anyone have any tips or tricks that they feel help these bigger trees get established faster? One's 2.5", the other is easily 4".

I know there are constant debates about various fertilizers, root stimulators, etc., so I was wondering what everyone uses.
