I'm not sure I understand your question. Are you looking to buy a canistel or do you already have one?

Why would you want to cut a tree so small? My canistel has the first scaffold branches at 6' and these older branches are the first to bear.

Also my canistel branches hang low with fruit and break easily. I camnot see any benefit from a canistel bush.

Even 50 cm is VERY small canistel I know of are going to take 5-6+ years to bear from a large 3 gal 120cm tree
