When it comes to pugging, I'm beginning to 'dig it,' as in 'can you dig it.'
For instance, last year I did some substantial pugging on one of my 'Tikal' sapodilla/nispero fruit trees, in the form of doing some substantial branch and fruit pruning.
With regards to the fruit pruning, this was done when the fruits were about half an inch wide. The fruit pruning was done to about one half of the sapodilla tree. The tree is over two stories tall.
The objective of this pugging was to increase fruit size and quality.
Well, this year, I've done no such pugging. But, I have noticed an increase in fruit size and quality as a result of last year's pugging. For instance, this past week, about 8 sapodilla fruits were picked from the tree that had the size of a small-medium mamey fruit, which is huge for a sapodilla fruit, now that's saying something. I've never seen a sapodilla fruit be that enormous, especially for a 'Tikal' sapodilla which are know to be at best a small-medium sapodilla fruit.
Now I'm thinking that if I had pugged the whole tree last year and pugged all the fruit, - pugging the fruit is so much more tedious than pugging branches - perhaps I would now be having a sapodilla crop with a larger quantity of giant sapodilla fruit.
Perhaps some fruit varieties react with better fruit production than other fruit varieties. For example, after doing some severe pugging on my 'Keitt' mango trees, they respond with a production of giant, cannonball sized fruit!
Therefore, since the 'Tikal' sapodilla responded so well with larger fruit after pugging, and, the 'Hasya' sapodilla is a larger fruit that the 'Tikal,' it seems probable that by doing some adequate pugging to my 'Hasya' sapodilla tree, - when it reaches a height of 2 stories - that it will then produce larger than normal 'Hasya' sapodilla fruit. With any luck, the 'Hasya' will respond to the pugging even better than the 'Tikal.' And, the heavy production of 'Ox' (*) sapodilla sized fruit that I and others have been looking for will be finally attained.
(*) 'Ox' is one of the largest known sapodilla fruit varieties. The major problem with 'Ox' is that it has low fruit production.
