Yes I am---however, you will find many "qualified" people in this forum to help you. In fact, many of the excellent contributions made here are not necessarily offered by members with formal qualifications. One of the "side effects" gained thru enjoying gardening and being a gardener is that an increase in plant knowledge naturally follows. Regards.

Experimentation is fine if it is based on understanding the peculiar aspects of what ever plant we are dealing with. When it comes to Australian native Proteaceae plants there are unique considerations that need to be taken into account. Once we have an understanding of these characteristics then by all means we can take advantage of them. Experimenting blindly is not nearly as constructive. Australian Proteaceae plants are sensitive to Phosphorous to varying degrees. BUT it all makes sense if we are aware of what their original environment was. Proteaceae from the skeletal sandstone soils that have always been very low in nutrients, especially phosphorous, have over thousands of years, developed special adaptions known as proteiod roots. They are noticeably different. (I shall spare you further details about Proteiod roots, but a Google might give you more.) Plants developed these in order to maximise the surface root area so they can absorb the scarce nutrients that may be present in these sandstone derived soils. However in the more nutrient rich rainforest zones it is quite possible that Proteaceae are more tolerant of nutrients and maybe even Phosphorous. I always err on the side of avoiding common fertilisers with high rates of phosphorous. Even chook poo can cause problems, although I do give my rainforest plants a dose of Dynamic Lifter once a year. For example, I find Banksia ericifolia to be very sensitive while some Grevilleas are a bit more tolerant. As for your last remark Nathan I assume it is a joke. Anyone being wrong, should not inferr anyone is not wanted.

Hi funnelweb, appreciate your reply but Phytophthora is a serious issue in the bush and we have to be careful. On the issue of "is it or is it not" a fungus - and this is a sidetrack to the real issue - Phytophthora is a member of the Kingdom Chromalveolata where as a fungus is a member of the Kingdom Fungi - in the evolutionary process both are thought to have had a common ancestor but took different evolutionary paths. And yes, scientists are still arguing over the above points. The real issue with Phytophthora is stopping the spread - I live in an area with no recorded Phytophthora infestations and yet often work in Phytophthora infected sites and the last thing I want to do is bring the disease into my area. In applying Phytopthora protocols to ensure I am not responsible for the spread I have to assume that every site I work on is Phytopthora free and thus I apply the correct practices at every site to protect that site. Never assume that Phytopthora is everywhere - it isn't. Do you know for certain if you have Phytopthora on your property? Has this been confirmed by the authorities? If yes, what steps do you take to ensure you don't spread the disease to areas that are not affected? Phytopthora can be spread by soil particles on your boots, do you think about that when you go for a bushwalk? The chances of Phytopthora spreading from Australia are remote as most Australian natives are propogated in the USA by seed or cutting, not be Jumbos loaded with 6" potted plants, and even then the soil would have to be treated to be Phytopthora free. I really don't think we need to be putting the fear of Phytopthora into "jeeboo" or any of our other overseas friends who are discovering a passion for our wonderful Australian natives.

I only used slow release native fertiliser at planting, same with all the other plants.
