How do you propagate Fritillaria?
Actually Fritillaria seed ripens in mid to late summer and the seeds is best
sown as soon as it ripe or soon after in autumn. While the older Fritillaria seed
may still be viable it develops germination inhibitors that can make late
sowings germinate erratically. The Fritillaria plants have evolved to have
dispersal of their seed by the wind which results in their being adapted to
germinating on the surface of the ground. So it is vital to sow the Fritillaria
seed on the surface of the compost and not bury it any deeper. But the Fritillaria
seeds should be covered by a layer of grit about ½ to 1cm deep to help retain
moisture. The compost should be gritty (and so free draining) and a simple mix
of ½ grit and ½ of loam-based compost works well.
Furthermore, water the pots and then place
it in a cool, sheltered place out of doors such as in a cold frame. How do you
germinate Fritillaria seeds? The Fritillaria seed actually requires a period of
cold (but not freezing) to initiate germination, which means the pots can be
left outdoors through the winter until they germinate which is usually in the spring.
In mild winters it may be required to provide the cold period artificially by
placing the pots in a refrigerator at about four centigrade. Check the Fritillaria
seed regularly for any germination and then remove immediately to a bright
place to prevent etiolating of the seedlings in the dark.
Once the Fritillaria seed is germinated
keep the pots in a sunny position and keep watered throughout the growing
season until the Fritillaria seedlings start to die down for their summer
dormancy. While growing, the plant will benefit from a half-strength feed of a
balanced fertilizer applied one a fortnight. By the end of the 1st year,
the baby bulbs will be small and difficult to handle, so are better left to the
end of their 2nd year before any re-potting. Expect a
"typical" Fritillaria to take five to six years to flower from
sowing.
