Last November, I stratified Quercus bicolor or Swamp White Oak acorns that two large trees profusely procuced in a park where my kids play. Here is their progression since spring.
April 11, 2021: planting the acorns
The acorns sprouted in the refrigerator and we can see their roots through the plastic bag. I disposed them uniformly in the pots and covered them with a layer of potting mix equal to the thickness of the acorns.
May 15, 2021: leaving earth
The young Oaks emerge like arrows before deploying their cotyledons.
May 27 2021: first leaves
The first solar panels are operational.
July 15, 2021: second growth
We can now see the first true leaves, with their detailed lines and their red color before they turn vivid green.
