Double Sprouting

By Harriet Tupper | June 27, 2016

Here are two photos of acorns collected at Hackfalls end of April and now germinating. They are Quercus macrocarpa and Q. crassifolia. If you look closely, all the acorns illustrated have two roots and two shoots. This seems to be the Quercus equivalent of having twins. Will these grow into decent trees or will they always be a bit of a problem because of being double? and is this normal?
