Re: Blechnum penna-marina


B. penna-marina grows natively in the mountains to the west of Canberra, in high sphagnum bogs. It's used to cold weather and survives happily under feet of snow, but it must have "wet feet" all the time.

It does experience quite high daytime temperatures in summer (up to mid 30's C), but usually cold nights.

It tends to grow low down, out of the wind.



Canberra, Oz.

Dear Fernatics,

During May I imported a lovely Blechnum penna-marina, from the UK. I
planted it in a pot, as it was easier keeping the moisture high, through
our very dry winter. It really did well, up to  two weeks ago, when I
saw it is no longer as happy. I still keep the humidity high and soil
moist. I have it an area that gets light, but no direct sunlight, on a
bench in my fern-garden. Currently our natural humidity is 25% and we
cannot wait for the rain to come. During the past two weeks we had
rather high max. temperatures of 33 - 35 degrees C. Could this be the
reason for my Blechnum not to be so happy?

I would also appreciate any other tips on growing Blechnum penna-marina.

Frondly regards

South Africa
