Post Re: Tree ferns after 40 years
I dont know if you in rainy climates know this but a non trunking tree fern- even with adult fronds,is easy to keep here. Once they trunk? Its like I cant water them enough..everyday isnt enough. It get worse by the year.
I should dig up C.brownii..its just a runt. To think it was off to a fast start 10 years ago..now going backwards. yes,I water it.

Thanks Boris and Mau, you could almost say that tree fern culture rejuvenates you!
So just go on here with this hobby :mrgreen:

Stan, I know it can be very dry in California, but that's no reason to not have a good trunk growth! I get the ferns every day soaked from the growth point, but also the soil under the tree ferns should always be moist.
I consume on average 8 months per year 400 liters of water every evening.

the rainfall is + - 750/800 mm per year in the Netherlands, but not sufficient for large tree ferns!

Eduard.

Dear Eduard, my congratulations on your birthday and 20 years with tree ferns, my favorite plants! You made fantastical work! Very beautiful pictures, pretty sure birthday party in your private "cloud forest" was great!

In your honor I gave name of my Dicksonia squarrose - "Eduard":)

Thank you!

Roman

Eduard - A bit of a mystery there. You spend much time watering every day, your tree ferns get older and bigger and yet you get younger looking. Is there a lesson to be learned?

Thanks John I will try , the day before I was born my mother was still working through the New Zealand garden in Wellington, and the neighbor came and told her you get a garden artist.

I'm not sure but think that my beautiful girlfriend in combination with the passion for plants, not too much food, everything in moderation keep me young!

Of course there are cracks, but you did not see in the picture :wink:

Post Re: Tree ferns after 40 years
Hi tree fern lovers, here is my latest update of this year.

This year was a good year for the tree ferns of temperature but to dry, I had to give a lot of water, luckily I had this year groundwater at my disposal!

Also my good places to put tree ferns are scarce. I had to be creative and have fortunately devise a good solution.

I'm also stopped expanding the collection, have too much. I got the double tree fern species first discarded, also think this is not enough the most cyatheas grow very big and I will have to make difficult choices!


I start from the living room to the veranda with tropical palms to the garden,

Image

Image

Image

Image

The C spinulosa grows well, not too big but nice,
Image

Image

D. fibrosa with green trunk've removed the skirt ! ,
Image

Summer photos of the C.medullaris,
Image

Image

And now late Oktober in the rain,
Image

We come to the New Caledonian species, they also make nice trunks,
Image

And the fernborder with in the middle the C.atrox var. atrox,
Image

Situated between the B.brasiliens,
Image

Image

Image

Image

The C.brownii. var. [Aussie Larrikin '] is also doing well they have little space to grow well,
Image

And C. australis coming back good after root pruning last year,
Image

Looking back to the house,
Image

Image

3rd garden area with C. c. revolvulum,
Image

Blechnum tabulare working on his late 2nd flush,
Image

D.squarrosa trunk growth well,
Image

D. antarctica it continues to do well in the old pot,
Image

4th part where I have created the new space, about 7 sq m,
old situation,
Image

Image

Image

Unfortunately there fit not many tree ferns on it!, only two being C.viellardy and C.cooperi from La Reunion,
Image

Image

What should have been C. glauca from La Reunion from spores but grow as cooperi as Steve told grown into a beautiful cooperi species,
Image

Image

And the C. viellardy,
Image

Image

For C. cooperi I found a new place, there should be pruned even more from the trees for better growth,
Image


And already the last images of this update from within 2nd floor

The tropical tree ferns stand for a while in the warm conservatory.

The mamaku,
Image

Eduard.

Eduard - Marvelous ferns and photos.

I can hardly belive you manage to achieve such sizes in relatively small pots. My D. antarctica here has grown well over the past year but is already in a 50cm pot and it weighs a fair bit, having just moved it inside due a threat of the first frost (+1c). Tmorrow it goes back out for a huge rainstorm. I don't want to increase the pot size for a few years and wonder what you think of top-dressing with rotted leaves frequently. I think next year I will have to add automatic watering and mist several times a day as the real growth flush doesn't really start until late July here and see no reason why it shouldn't grow quickly from late May onward. The last frond came out 10 days ago.

Eduard - Stunning, and as inspirational as ever!

John in Halifax - Does your D. antarctica continuously produce fronds all through the growing season? Could you post a photo of your plant?



Cheers

Andy

John, so I work for years, I make from all the old tree fern leaf compost, it must be digested properly and I add blood and bone meal to add powdered [I grind the grains in an old coffee mill] and create a good mix then add 2 cm above the root ball and irrigation washes it slowly along by the roots.

It is important to keep some space at the top so you can continue to add some compost!
The D.antarctica pot is from 2010, and that of the D fibrosa from 2008, So you can go a long time with proper fertilization :wink:

About growth here, I have a big flush in May [between 20/30 frond] before the flush was smaller and there were also solve fronds until September!
This I still have on the D.fibrosa.

Eduard.

From what I can see, there could be room to expand your collection rather than cutting it back. they're now at a height when underplanting is an option. Ok, so overwintering could be a problem :lol:

Hi Gary, I use all the good spots out there in semi-shade, more good space is not there, for smaller plants for the understory have no place to store it in the winter in the greenhouses, everything is full!

I would be able to choose to put more plants in the ground, but we have a colder climate here, and it is too expensive to protect everything :wink:

Other open spaces have full sun and that burn the tree ferns literally away.

I have everything for 90% in pots and can store everything so quickly, and I have the ability to create other composites in the garden, as I have in winter a north European garden and a subtropical garden in the summer.

And I have on this subject ever talked with Steve Pope, "it would be ideal to convert a large greenhouse on the garden", but unrealistic and too expensive, we have to make choices :mrgreen:

Eduard.

Thank you Jose, with such a reaction is certainly nice to share my experiences with the tree ferns here!

Here one I forgot! The C. milnei, he stood in the fern border and not see properly, have it removed for the photo shot,
Image

The trunk gets a nice base now,
Image

And an autumn shot of the C. medullaris.
