The soaking was a good idea, but now they need to be sown in 
pots and put outside in a cold frame until they germinate next 
spring.

A general rule, with a great many exceptions, is that seeds 
germinate around the same time mature plants of the same 
species leaf out in spring (or fall or whenever).
