Title: Woodwardia unigemmata
Post by: Véronique Macrelle on December 23, 2019, 10:50:53 AM
my Woodwardia unigemmata (2nd winter in open ground) produces 3 bulbils on its fronds. these are small fluffy balls of 3 to 5 mm.
 do you know how to make them become a fern? how to propagate this fern from the bulbils?
for now the leaves do not seem to suffer from the cold .. but it has only been - 6 ° C last week..

I would  remove the  bulbils  now  and pot them up, cover them lightly  with a  neutral ph substrate  and  put them somewhere  sheltered - I think they will sprout  in spring.  :-\

here are the photos of Woodwardia: it has only been planted for 2 years, and is still small: only 3 leaves this year, one of which is 80 cm long.


then the few bulbils on the leaves

Asplenium bulbiferum produces bulbils also. In the first pic you can see them attached and second pic is one detached waiting to be planted in a small pot. They take fairly easily.

At the end of December, I cut the ends of the leaves and buried them in potting soil.
today, I went to see a little underground, it seems to me that the bulblets thicken..

finally 2 years later, by trial and error, i found how to do it.
 of course the fronds are now fuller, and the bulblets a bit thicker too but the Woodwardia ( 5 nice fronds) is not yet mature enough to make spores.

It is better to leave the bulblet on the frond and treat it as a marcotte, which it probably does naturally.
 But the production of the new fern is accelerated if I bury the bulblet in a pot of potting soil. another method according to a fern grower, is to bury the bulblets under some plant material. But according to him it takes longer than germinating spores!

however, my little bulbils, which I put in a pot of potting soil in october, are now swollen to about 3 cm, blond in colour as far as I can see, and are developing nice roots.
I cut off the ends of the fronds: they have been free for 1 week.
2 out of 3 are starting a new leaf.
