Re: Signa seed - PCI

 

One of my experiences with PCI seeds is interesting. I had planted them in a plastic seed box in my basement and after some length of time I don't recall, I left them ouside for the summer and forgot them. Came spring, after a colder than normal Minnesota winter (Zone 4) I had PCIs looking like grass  in the box in early spring. Surprise! but not so surprising, only a very few survived the next winter. I have had tenax and douglasiana survive a couple winters here but then die. I think I lost all five the next winter.        Joan Cooper     Roseville, Minnesota

Soaking is what is recommended for old seed. I have not had any
success with old seed - well, just once.

I grow a few hundred PCIs every year. I have no problems germinating
the current year's seeds. No toilet tank. No soaking. No fuss. I
sowed lots of different Pacific Coast hybrids on December 8, kept them
in a corner of the kitchen which is about 20 C (65 F) in the daytime
and cooler at night, and they germinated last week. They are now in
an unheated greenhouse which is usually about 5 C (40 F).

Ones I sowed earlier are now 5 cm high (thumb-length).
