F - your soil choice dictates what size your pot can/should be. When you use heavy soils that support significant volumes of perched water, pot size can be critical because you need to guard against over-potting. As your soil becomes less water-retentive and the perched water table disappears, over-potting is relegated to nonissue status, leaving you free to pot even tiny plants in large volumes of soil. Soil volumes that ensure room for roots to run offer better opportunity for plants to grow at as close to their genetic potential as possible. No plant likes tight roots. When it's said of a plant that it likes tight quarters, in most cases what's being said is, the plant doesn't like wet feet - so it's better to grow the plant tight to eliminate much of the predisposition to root problems resultant of a heavy soil and the accompanying water retention. In essence, the stress of tight roots is preferable to the possibility of impaired root function or root rot - one limiting factor being chosen over another, or choosing the least of two evils. Choosing a well-aerated, free-draining soil and a larger pot eliminates BOTH problems, so what's not to like? ;-) Al

Hi Mike, I am not sure whether it's too late. Have you been visited the pantip website. It's a very nice plant lover community on the web for Thai people (similar to gardenweb). The only thing is that it's a Thai language website. But I'm sure you will get many friends there that are able and willing to talk to you. here is the link: http://www.pantip.com/cafe/jatujak/ Sunnybalcony

goldhills - I'm sure its a swallowtail of some sort - - one idea is to get into the University of Southern Queensland or Griffith University and find out who is doing a thesis or doctorate on butterflies of the region - - that's how I got a contact for the bats around home. I'm off to a biology residential in armidale in two weeks - I'll ask around the University of New England to see who the experts are. It's amazing - most professors or doctorate students are more than keen to help out individuals with their queries. Also - the Queensland museum has a great enquiry centre - they might be worth checking out. I got all of the sites through google and I don't have them bookmarked cheers Tony

As I have tried to make clear previously, I don't dispute that high P levels are relatively more toxic to Proteaceae than to other plant families, but I do believe that many rainforest grevilleas are less susceptible than WA species. Again its a relative thing, and I have certainly found one that isn't. A landscape supplier dumped a truckload of potting mix in my garden, close to some trees but about 6 metres from a G. baileyana. Some months afterwards it died, and on digging up the mix it was full of proteoid roots! Retrospectively, I have realised I have had a much higher proteaceae failure rate since using that mix, so I must find out what's in it. The seller told me it was fine for natives - you'd think that at my age I'd know better than to trust a salesperson, but my problem is I can remember back when most of them were trustworthy. Tony
