Marianna 2624 compatibility with Almond Varieties:
There is considerable difference in the degree of compatibility of almond varieties on this rootstock and also their productivity. Also be aware of increased incidences of Union Mild Etch considered by some to be incompatibility; new research is pointing to excessive irrigation practices contributing to this problem.
