Following a few simple rules, you can grow a mighty oak from a tiny acorn
A master gardener recently asked me how to germinate acorns because she had repeated failures. To be successful, collect the acorns soon after they have fallen from the tree. Never collect acorns that have caps still attached because those acorns are most likely empty. Only solid, firm acorns that have fallen from the tree without caps should be collected. A healthy, well-developed acorn is one that has separated from its cap while still attached to the tree.
