🌱 Cork Oak Germination
Apr 19, 2025 repotted
Long tap roots, about 8” total, with 6” below the acorn.
Three placing the tap root below a small hex tile. Wired in place. I believe roots will not encourage roots above the tile. (May attempt to correct this).
Two cut the tap root off, root hormone, and wired in place without a tile. Borrowed technique from JBP, for nebari.
Added a pinch of organic fertilizer on top.

Cork Oak Seed Germination
With cork oak, it’s simple enough. Here’s how to germinate their seeds:
Soak cork oak acorns in water for 2 days, any acorn that still floats after that time are no good, discard them.
Fill pots almost to the brim with peat-free compost.
Make sure your pots have drainage holes in the bottom.
Plant one acorn per pot, at about 2 cm deep.
Protect the pots from predation! Mice, and squirrels love acorns. Covering with fine wire mesh will work.
Keep soil moist, cover and avoid placing in direct sunlight.
They should germinate within one to two weeks.
