@aheartforhome,
This was @scottfsmith’s report from 2005/- 2015. I could not find a newer version. Scott lives in MD.
Scotts stone fruits variety experiences 2005-2015.
Shiro is one of the best pollination partners. It is also productive. Fruit taste good if you let them hang for a while.
To me, most Asian plums taste similar, juicy and sweet. Lavina has nice aroma to it.
I am not sure how minimal spray you can get by growing plums. The most troubled plum disease I dread is black knot. Neither Euro or Asian are immuned. Not even Shiro.
