I was graciously given 7 Concordia Oak acorns in 2018 from fellow member (Letemgrow) of this site. All seven sprouted in early 2019, but they did not grow much their first year. This past winter, I moved the seedlings from a raised planter bed to a large pot to give these trees one more year to do something. All seven trees are less than 8" tall. I have other oak seedlings twice as tall that were planted as acorns five months ago. The Concordias are in the same potting mix as all my other trees that are thriving and have sun the majority of the day. They look healthy, but they are just small. I cannot find anything online that discusses their growth rate except to say that they produce acorns early. Is this the normal growth rate for Concorida Oaks?
