Title: New dwarfing white sapote variety?
Post by: BonsaiBeast on January 13, 2021, 09:43:12 PM
A friend of mine showed me a mysterious white sapote tree on his property in Solana Beach. He says that the tree could be up to 50 years old.

Whats interesting is it appears to be incredibly dwarfing by white sapote standards. The tree has never been pruned.

Any white sapote experts to weigh in on whether or not this tree might have some potential for propogation?

Looks interesting,Hows the fruit?
Trunk size is not that big for an old tree.
Any fuzz on the leaf underside indicating possible Tetrameria hybrid?

Must be some poor soil conditions there because I have a tree that's maybe 25+ years old that's my rainbow seedling that was planted from seed that's twice as big in trunk size as that tree in pic. But like Jonah mention how's the taste that's what is important. Not that size isn't important the only tree that I have out of collection from Bob Chambers collection (40 varieties) that is some what dwarfing so far are 'Salad' and 'Bravo' those two trees have stayed small compared to other varieties.
You should get scion wood and graft onto seedling rootstock and see how it grows for you.

I have a number of Sapote trees here in Nipomo.  My oldest tree is a monster, 2 ft diameter trunk.  It is grafted with Pike and Vernon, bushels of fruit everywhere enhanced with fruit flies.  I also have two dwarfed trees, one a Pike, one a Vernon.  Both produce normal sized fruit.  Each "tree" is approx 4 ft tall, and is over 15 years old.  These are the same varieties in the monster tree nearby.  The difference is that the C. edulis "Pike and Vernon" are grafted on yellow sapote rootstock C. tetrameria.  Obviously no incompatibility with more than 15 years since grafting.  One is in the ground, one in a half barrel.

Conversely, yellow sapote, c. tetrameria, grafted on c. edulis results in a semidwarfed tree, about the size of a peach tree.  I have both #6 and #7 varieties of C. tetrameria grafted on white sapote, C. edulis.  Each tree is approx 15 years old or more.

It seems that the size of white sapote, C. edulis, could be controlled with the use of a C. tetrameria interstem a technique used in apple dwarfing.  Perhaps then, a white sapote tree would fit in the average city-sized lot.
