Sounds fun S.G volunteering at a school!
I bought a budget friendly bare root Josephs coat climbing rose for $3.99. It is soaking in a bath right now.
I decided on a maple vine for an empty area where I've been wanting to plant a tree. The maple vines are truly beautiful. The vine I am thinking about grows small and narrow and is more hardy than the Japanese maple.This one in particular has red bark.
There is a tree farm near by. They sell grafts for $14
I am not really sure what a graft is compared to a 2 gallon. When the time comes I will ask.
