Watch out for grub holes in the shell,get quality acorns from the tree just as others are falling.Plant on surface half buried either on its side or point down.Potting mix-50% pumis,25%compost,25%commercial potting soil.Styrafoam cups work great as a pot,just rmember to punch in a few drain holes.When repotting use the same soil mix,coarseness as well as drainage is important for healthy root development.Plant the small tree in a 1-3gal. nursury pot at a level so the remaining acorn is resting on TOP of the soil.Keep out of direct sunlight for about 3 weeks,then place into the yard and treat it the same as any potted plant.Do not fertilize for 1-month after repotting.
