EMLA 9 has a dwarfing influence on all scions worked on it. It induces cropping early in the life of the tree. Moreover, the fruit is larger and ripens earlier in the season, especially during the early years of the tree’s life. Trees on EMLA 9 show a wide degree of tolerance to soil conditions, withstanding heavy soils and wet conditions. It is not, however, suitable for dry light soils. M.9a is a weaker rootstock than M.9. EMLA 9, though virus-certified, is distinctly more vigorous than M.9. All 9’s rarely sucker, but their roots are brittle, and trees on these rootstocks require staking throughout their life. EMLA 9 is resistant to collar rot (Phytophthora cactorum). It is susceptible to mildew in the nursery and a regular spray program is recommended.
