Will solitary oaks bear acorns?
Over 20 years ago, we planted three different oak varieties on our property: willow, red and white oak. Sadly, our red oak recently died. We are not aware of any oaks in the gardens of our neighbors. I realize oaks take many years to produce acorns, but will they do so without another nearby like specimen? I am aware that some trees need another to bear fruit (e.g. apples, chestnuts, holly berries). Do we need to plant companions for our remaining willow and white oaks?
Oaks do not need another for pollination to produce acorns.
