It can take two years for some seed to sprout. If you get 80% germination
(insert any %) from a cross, some of the unsprouted seed will/may sprout the
next year. Some people chose to accept that number and move on. My practices
change year to year, but I usually lift the seedlings from the pots and let
the pots set another year--especially if it's a favorite cross. Seed that
were too deep might benefit from the soil level changing. Some seed never
sprout.
In recent years, I've been getting 50% to 60% germination and finding soured
or spoiled seed when I dig into the pots. I have no clue what is causing
this. The only change I'm conscious of is the switch from leaves to pine
needles for the cover.
This year I was sick and didn't get my pots covered at all and, now, I've
set the pots in near full sun. It will be interesting to see how, if at all,
it differs. The sprouting seems to really be taking off with the warmer
weather.
This year, my same pod parent crosses (but different pollen) are beginning to
sprout at the same time. I've not noticed this happening before. In 1991 I
made 10 crosses onto IMMORTALITY. I found several of these showing sprouts
when I returned from winter pot luck-2/25/1992, another sprouted on March 19
and the rest were scattered in between.
