Unlike grant I find they wire easily ( care to elaborate on that Grant? ).

They are in my list of easy care trees, and I cannot think of any reason why anyone would not have one :lost:

I just avoid using wire on Banksia; to try and get a more natural feel and look.

If you do wire you do it very lightly and avoid wiring down branches as they lose vigour.

Grant
Ok thanks. only ever wire the younger shoots before they lignify, Never had any go below the horizontal and so far no issues :-) :fc:

Yeah, I found this too. When I started wiring my banksia I tended to lose branches. I have never had any success at all with the species in general. I have tried Integrifolia, serrata, marginata and spinulosa. I would eventually lose all of them. I absolutely love banksia and think they look spectacular as bonsai. I am very jealous of people that grow them well, and seeing a few of Grant Bowie's was what inspired me to try them again, but I still lost them, and got frustrated at continually losing them that I gave up. I guess I should probably try again, but I think maybe the humidity and lack of sun doesn't help where my bonsai are. I planted a few Integrifolia at the front of our house for the garden that are doing very well and attract beautiful native birds, so the humidity can't be a problem for me, it must just be me and either watering or cutting back too hard that is the problem.
I have my larger ones in full sun. the smaller ones are in Dappled shade of Gum trees.
All are potted in Diatomite / Zeolite

Marginata is one not suited for high humidity areas, so Central coast or coastal suburbs of Sydney may struggle to keep them alive..

B integrifolia should do fine most places; mountains, plains or coast, Tasmania , Byron Bay even Perth. There are 3 varieties so you might wish to choose the better one for your area if you can.

B serrata is replaced by B aemula as you go north to Brisbane and further north; so if you are in a high humidity area I would recommend B aemula or B paludosa rather than serrata.Melbourne seems to be close to the edge of the natural southern range for B serrata and there have been some failures of old B serrata in Melbourne.

Still can't think why B marginata would struggle where Shibui lives!

What about the "ericifolia" as worked on by PeterH (viewtopic.php?f=69&t=7847&start=0&hilit=banksia+peter), where would that fit into your extensive list?

Hi all,
That is a magnificent bonsai PeterH has crafted. A real credit to him. Peter Banksia :clap: :clap: :aussie:

Ericifolia can grow up in the mountains(Mount Banks funnily enough) in the Blue mountains and right up the coast towards Brisbane so should do fine in a variety of climates. It also does well in pots in Perth.

There's a couple of possibilities I'm exploring Grant.
1. Provenance. Most of mine are seed grown from local trees which are quite rare in this area since superphosphate and agriculture. As mentioned earlier I have talked to some botanists who had noted several differences in coastal and inland forms of B. marginata. There was even talk of splitting into 2 species but that has not yet happened. It may just be that the form in this area is not particularly hardy and may not be suited to bonsai.
2. Phytopthera. WA banksias are quite susceptible to this fungal disease and I have always had trouble keeping them alive in pots and in the garden. most Eastern banksias are relatively resistant to it but maybe marginata (or even just this form) in susceptible enough to make a difference.

Whatever it is that's affecting my trees, this thread has stirred quite a lot of valuable info and ideas on cultivating banksias as bonsai. Thanks to all the contributors and please keep it coming.

Marginata maybe should be split into a number of sub groups.

Phil E from SA club showed me some really weird looking Marginata along the highway from Adelaide to Melbourne a few years ago. They are very variable!

You may be right and the strain near you is not a strong one.

I think everyone should have a B integrifolia in their collection, they are stunning bonsai material that reduce well.
There have been B integrifolia in the national collection through the years that are brilliant examples of the species.

Ahhhh! Look, I don't know... Thought I was just sticking in my :2c: but now it seems after the responses/images maybe I was missing something and I'm off in search of some new stock! Banksia Integrifolia... it's found a spot on the list, my wife is stoked! Thanks for the inspiration all, always happy to be persuaded on pretty much anything!... :yes:

This is a B integrifolia new to display in the NBPCA collection although it has been in the back of house getting into good condition for 2 years.

It is a very big tree with a fabulous base/spread and natural shaping.

I do love that bonsai, but for me, the nebari looks a bit contrived. Just my opinion.

This is definitely one of my favourite looking Integrifolias I've seen on this site as it looks exactly like the Integrifolias around here.

Grant, there was one you had a snap shot of in a background picture I recall. I think it was your personal collection... it was breath taking, but can't remember what the post was about.

Sorry, need more information.

If it is my B integrifolia that won the Ryuga prize in Gold Coast convention then I have donated it to the NBPCA.
