I just purchased a Dwarf Washington Navel Orange tree. I can't remember if I should plant it so the graft is below the soil line or is it okay to have it exposed above? |
It is recommended to plant the graft (bud union) above ground so that it keeps dry, and is less susceptible to fungal diseases, such as Phytophthora, which is somewhat common with citrus. Along the same lines, don't allow this area to be hit with lawn sprinklers, hose watering, etc. |
