Breaking Seed Dormancy for Fire Dependent Species

I wanted to pass on a trick someone sent me, for starting
seeds for container growing. This is a alternative to Hot Water Treatment, or
Burning Duff on Flat surfaces.

Seeds are interesting. So far I've had extremely poor
results with A. glandulosa, and mixed results with A. glauca. I soak the seeds
in a dilute solution (1:85) of liquid smoke seasoning and water for between 10
minutes and an hour, then plant them. I've had germination rates between 0 and
50%, but when I leave the flats alone (after extracting the seedlings that have
sprouted!), sometimes I get sprouts the next year .I'm growing some cuttings
and seedlings, but I try to get them planted out while they're still small. My
planting mix is 1 part sand, 1 part commercial potting soil, and 3 parts
perlite. Small pots get watered just about every day; slightly larger ones get
watered 3-4 times a week. I keep the plants in mostly shade (they get a couple
hours of sun in the morning, after that they're in dappled to full shade for
the rest of the day), and they're elevated off the ground so the pots never
ever sit in a puddle. I'm a hobby local native plant propagator, and this is
what I do for all my plants.The impenetrable
shell of a Manzanita seed has a little plug that becomes permeable upon contact
with smoke. Neither heat nor physical scarification has much effect on
Manzanita seeds. Smoke is their germination cue, and liquid smoke seasoning is
the elegant solution!
