| Maintenance |
Prune early to strengthen |
| Propagation |
Seed - sow early February in a greenhouse or outdoors in March.
Germination is often poor, usually taking about 6 - 8 weeks.
Stratification is said to produce a more even germination so it is
probably best to sow the seed in a cold frame as soon as it is ripe in
the autumn. The seed remains viable for up to 5 years if it is well
stored. When large enough to handle, prick the seedlings out into
individual pots and grow them on for at least their first winter in
pots. Plant them out into their permanent positions in late spring or
early summer, after the last expected frosts. Alternatively, if you have
sufficient seed, it is possible to sow in an outdoor seedbed. One report
says that it is best to grow the seedlings on in the shade at a density
of about 550 plants per square meter while another report says that they
are best grown on in a sunny position.

| Pests and Diseases |
Seed chalids typically
destroy 8 to 10% of white fir seeds and have destroyed up to 60% of a
crop. Cone moths, cone midges, and cone maggots also reduce yields. In
California and Oregon, the Douglas squirrel cuts and caches cones, but
generally takes less than 1% of the cone crop. Deer browse on
young shoots killing them.
