#1. I want to get into junipers but i'm having trouble finding small
starter stock. Could i buy the 1 gallon size and just prune them back
?

#2. My dad has several very scraggly junipers that have not thrived on
a hill where he planted about 75 of them several years ago. Why not
replace a couple of them with big healthy gallon sized nursery ones
and work with the scraggly ones as bonsai ? Think that could be done?
