Juania australis

[AJQ]

Here are some shots of my Juania, it has seen 5 winters now with out a blemish. The wind though is a different story.....

These shots are from last September so I need to get some updated ones.

Looking good Andy. Do you protect it at all during the winter? Can't remember if I asked you that before.

Gav, No I don't, it has never had any protection at all. I just let it do it's own thing.

Regards Andy.

Hi guys as promised a few shots of the Juania australis growing un protected here in the UK.

These are 300 miles from my house and all though not the sole reason for going so far it still was quite a journey but well worth it.

[kristof p]

earlier this week i was at the robinson garden in earlscliff (ireland) and saw what is probably the biggest Juania outside of Chilli. it looked very hapy on the spot were it is growing....

here it is with me underneath it for scale...

[Caryota_gigas]

There is a bigger one just a couple of kms up the road from me in NZ.

[gyuseppe]

I did not know that in Europe there are plants juania australis so big, beautiful plants and beautiful photos.

[Tyrone]

Amazing shots from the UK and Europe. It's probably the best pinnate palm for those areas apart from CIDP, and Butia's. It looks quite tropical too.

Best regards

Tyrone

[AJQ]

They look great Kev, where abouts in UK are they?

Mine is coming on well, the only damage I get is from the wind............

Edited to delete photo as it will not post correctly, I keep getting it 90 degrees right, regardless of how I edit it on Photobucket :rage: :rage:

Regards Andy.

Hi Andy.

Those beauties are from Glendurgan gardens near Falmouth and I have posted a few shots on our GOTE froum HERE........Kristof's was bigger though.

My own Juania got battered by cold last year but has come through but it has been set back at least a year.......wind is generally not a problem in middle England though.

Michael you cannot say there are bigger ones a few Km from you, I travelled 300 miles from those pics, we need pictures from yours now.

[AJQ]

Thanks for that Kev.

Yes Michael, you must post some piccies of the NZ one.

Regards Andy.

[Caryota_gigas]

I had been unable to locate photos on my comp of this palm, and have not had the time to shoot up the road to photograph it, but a friend sent me a pic, so here it is, taken about 1 year ago.

[AJQ]

Many thanks for that piccie Michael, I can't wait until my one gets to that size.

Regards Andy.

[Kev Spence]

Yes nice one Michael that looks a beaut!!! what sort of temps does it get then I suppose fairly wet with no extreme temps and minimal frosts?

[JasonD]

They all seem to have the spotty yellowing on the lower leaves that the established plant in San Francisco's Golden Gate Park has. Magnesium deficiency? It does not seem to change from season to season.

For anyone trying to grow this palm, remember to use gypsum. Turns out that higher calcium availability inhibits root rot in avocados, it would be worthwhile to do this for this palm as well. Gypsum is the only way to add calcium without raising the pH.

The one at Strybing is still alive, hopefully someday this plant will be readily available to try in Norcal.

This palm clearly lack some nutrient. K? Mg?........

[Caryota_gigas]

The one in Landsendt is a Male and is looking a bit better as it is now looked after much better. It now has a mulch of Mussel shells around its base which may be helping with its nutrient deficiencies.

It flowers quite prolifically each year now... it just needs a girlfriend

Do you have experience using gypsum for Juanias?

BTW _ Were are the "Santa Cruz" mountais located? Portugal, Spain, Latin America, California.......?

[Mauna Kea Cloudforest]

I don't have a juania, but based on what I've read and seen, root health seems to be the issue. We use gypsum on our avocados as research has shown it inhibits phytoftera root rot. It will most likely have the same effect on the juanita.

The Santa Cruz Mountains are south of the Bay Area, 100 miles south of San Francisco, 40 miles North of Monterey Bay.

Then try and grow it and report back to us. I think it is much more than just soil and root health issues, but I have not grown one either...

Those Juania in Britain are unbelievable. Thanks for posting!

I'm just concerned by the fact that, without a proper protection in case of exceptionnal cold, they will probably not survive on the long term. Even with protection during a polar wave, it might be quite difficult. The problem with the best micro-climates in the British isles is that you may have 50 years without a severe frost there, but when it comes, it's deadly. Remember 1985 and 1986. Temperatures reached -15ºC in Dublin, almost -10ºC in Cork (Ireland) and the weather station with the best temperature, Valentia, in the super-mild south-west corner nevertheless reached -7,7ºC.

In GB, -19º were recorded in Aberdeen, -18º in Glasgow, -12º on most of Scotland's western islands at sea level, -16º in Cardiff, -9º at the least frosty of the Isle of Man's stations, between -7 and -11º on the Channel islands and even -7º on the Scilly islands (another claimed zone 10). Actually, all of the Scilly's mature Rhopalostylis were killed during this winter.

So I'm not sure about Juania's chances on the long term there...

I might be wrong though (I wish I am).

It's just a shame that the only garden-enthousiastic countries in Europe are that far north. If Spain could discover there is a lot to enjoy with gardening, Juanias would be grown in one the the best climates for them (and for many other great plants): Galicia's lowland, in NW Spain.

Long range record low is only -3ªC in the bay of A Coruña and many places around are virtually frost free. High moisture, cool summers, no heat at all. Very reminiscent to Auckland's climate where I had the chance to see the famous "big one" at Dick and AnneMarie Endt's property.

[Keith N Tampa (ex SoJax)]

Phytophthora is virulent, adaptable, highly varied group of pathogens. The name Phytophthora is the genus and translates to "plant killer". It is probably the most damaging plant pathogen on the planet. One high profile disease outbreak is the Irish Potato famine which was caused by Phytophthroa infestans. Many of you from the West Coast of the USA are familiar with Sudden Oak Death which is caused by Phytophthora ramorum. Phytophthora palmivora attacks palms as well as Liriope and many, many other plant species. I point all of this out because I don't want readers of this particular thread to think that applying Calcium is a blanket treatment to protect plants from Phytophthora. I'm happy to have learned that it does work on Avacadoes, something I didn't know before. I believe this claim because I know of another disease; Black Root Rot, caused by Thielaviopis basicola, that prefers a higher pH and by keeping the pH below it's minimum threshold, the pathogen remains dormant. These examples reflect one of the 3 principals of controling a disease, make the environment hostile for the pathogen. Phytophthroa diseases are caused by many organisms in the Phytophthora genus so what works on the Avacadoes won't necessarily work on most potential host plants. I'm not saying you shouldn't try it or that it won't work, but I'm saying have realistic expectations. Chemical control of Phytophthroa is variable due to the limited scope of the chemical in question, as well as the pathogen's interaction with the host plant and surrounding environment. The rapid death of the Juania australis is typical of the way Phytophthora kills. Another cultural thing that might serve you well by makeing the environment less hospitible for Phytophthora is to plant on a hillside in well-drained soil. Phytophthora is a water mold and if the water is flowing downhill past your palm, the environment for the pathogen will not be as favorable as if the palm is planted in a site where water collects. Of course, it sounds like Juania doesn't like to be dry either. That means you'd need to keep the well drained soil moist at all times. Not an easy feat in a Mediterranean climate.

I used to post somewhat at "Infojardin" (Spanish gardening forum) and I know a lot of folks are trying to cultivate Juanias ,at least I know that in Gipuskoa in Spain they are growing well.

Excellent Alberto!

Muito obrigado!

The Basque country is indeed much milder than GB or Ireland. Only maybe a bit too warm in summer and still potentially exposed to frost.

Galicia and Asturias would be even better.

I have to go to work right now, but I'll read the full thread this evening.

Sounds exciting anyway

Thank you Alberto!!!

Those record lows may never be achieved again, who knows? Should people not bother to grow something just on the off chance that at some point in the future it may die in a cold winter?

I have a Juania in my garden too & the record low from my nearest 'official' Met Office weather station was -8C, also in the same year as those other lows you mention, but the lowest I have personally recorded in my own back garden in the last 12 years is -2.5C. My Juania has never shown any damage at all & is happily growing away now even in the middle of winter.

Yes they may not grow to maturity, but then again they might...

The Robinson Garden at Earlscliffe, Baily, Co. Dublin, Ireland

A video i took there in 2010, it is a very special palm when well grown. I made contact with the daughter of the founder of the garden and she wasw kind enough to give me a private tour seeing that i had come from Australia and new about the palm

After 4 years looking for this palm I finally get one. How are doing yours? Since this topic has been created in 2009 there must be some nice looking juania growing!

Any planting tips are welcome. and pictures too!

julien

[richnorm]

This is a dreadful picture as the light was too bright and makes it look terribly threadbare. This is actually a handsome palm now with a recurved look somewhat reminiscent of a Hedyscepe.

[AJQ]

My large one went down hill last August after being in the ground for 9 years....... Havent a clue why ????

It spear pulled about 3 months ago, I have been giving it H2O2 occasionally. It is completely defoliated except one frond, which although most of the leaflets have since gone the petiole is still green, as is the trunk........ I guess it us still alive..... Go figure :-((((

If it is phytophtora, why have the adjacent plams not been infected, Parajubaea sunka, Chaemadorea microspadix, Trachycarpus nova and princeps....????

The other two are just grand. :-)

[Darold Petty]

I dislike making negative observations but I don't care to grow Juania since it is subject to "Juania Sudden Death Syndrome". This palm will grow happily for years and then suddenly die: by the time trouble is observed it is too late. Efforts to salvage the plant are inevitably futile.

I grew five seedlings up to large, planting size palms. They were installed with the best of care at our Lakeside Palmetum in Oakland, California. Today one plant survives.

Any species of Ceroxylon is much more available, easier to grow, and more refined in appearance.

Where would you go about finding a Ceroxylon, Darold? I am not sure if there is a species that can make it in the EB, but I have never seen one available...

[Darold Petty]

Hi Ben, I have currently, as potted plants, C. echinulatum, C.parvifrons, C. ventricosum, and C. vogelianum.

I don't intend to plant any of these in my own garden. The seeds are rarely available, but I always purchase some when possible.

[Ben in Norcal]

I'll PM you Darold.

[AJQ]

Ceroxylons are like Hens teeth around here I'm afraid. Although I have managed to find a couple of alpinums which should arrive shortly. I will plant one of them, see what happens but info is conflicting on their hardiness depending on which source you read.

Any available in your neck of the woods are not available to ship to UK unfortunately.

[AJQ]

I suspect foul play with my Juania though, ( long story ) :-(

Hi Andy,

Where did you find them? I've been wanting to try a Ceroxylon outside for ages. Sorry to hear about your Juania, it looked great in those photos! They're beautiful palms, especially when young.

Thanks

Bump...

Looks like Kristof hasn't been on the forum since 2009 but I'm still wondering how his Juania does...

[Darold Petty]

Update on the last Juania at the Lakeside Palmetum in Oakland, California.  This palm has died, with approximately 50 cm of real trunk, 15 cm in diameter. 

[Kai]

That's a shame! It seems this palm needs near perfect conditions to not die.
