Before sowing
most broadleaved seed must be treated to overcome dormancy. Here seed is
mixed with sand and peat and placed in boxes with permeable bottoms before
being subjected to ambient conditions for up to 18 months before sowing.
Boxes of seed being treated,
are stored for up to 18 months in the open with netting protection against
predation and are subjected to the variations in ambient temperatures and
precipitation before being sown in the spring.
