Some of the older adult Wollemi Pines such as "The Bill Tree" may be more than 1000 years old.
 The most recent common ancestor of Agathis and Wollemia has been proposed to be at least 110 million years old (Early Cretaceous) deduced from the reported oldest fossils of these genera.
Here Tony learnt a lot about tree management within urban and park environments and also in Hamburg Botanic Gardens. During this time, Tony completed many expeditions plant collecting in East Asia, with the aim of adding to the tree collection and replacing trees that were lost in the storm of 1987.He currently holds a top in arboriculture Head of the Arboretum and Horticultural Services at the Royal Botanic Gardens, Kew.
The leaves are flat linear, 3–8 cm (1.2–3.1 in) long and 2–5 mm (0.079–0.197 in) broad. Comparison with living and fossilised Araucariaceae proved that it was a member of that family, and it has been placed into a new genus, beside the genera Agathis and Araucaria. Although less than 100 adult trees remain, they were thought to be widespread across Gondwana, an ancient supercontinent that existed before Australia broke off from Antarctica and began its movement north. Wollemi pine was found in 1994 growing in a remote canyon in Wollemi National Park, about 200 km (120 miles) northwest of Sydney.
Like many other Australian trees, Wollemia is susceptible to the pathogenic water mould Phytophthora cinnamomi, so this may limit its potential as a timber tree. It was known from fossil records and presumed extinct until it was discovered in 1994 by a bushwalker in the Wollemi National Park just outside Australia's largest city, Sydney. (Mark Lynas The Guardian, Wednesday January 24 2007) - So each person would need to plant about 45 Wollemi Pines per year to be Carbon neutral. genus of conifer in the family Araucariaceae. WollemiPine.co.uk has also teamed up with conservation partners Royal Botanical Garden, Kew. Thus, the recently discovered species represents a survivor of a group that was more widespread and diverse millions of years ago. However, a fungal pathogen Phytophthora cinnamonmi is one disease that affects many plants, including the Wollemi Pine.
A few Wollemi Pines in the wild were infected with Phytophthora cinnamonmi as a result of it being carried in on the footwear of unauthorized visitors. Hidden in a top secret location within a national park near Sydney, is one of the oldest and rarest trees on earth -- the Wollemi Pine. If kept indoors, Place in a well lit position one week in every month between May to September. It seems in general that the trees need to have -12 to -15 degrees centigrade for fairly long periods to actually kill them (as seen in central Europe in the winter of 2010/11). Pruning heavily can be done on the apical growth and the branches. The Wollemi Pine is one of the world's oldest and rarest tree species belonging to a 200 million-year-old plant family. Pollen grains described in the genus Dilwynites are common in the fossil record of portions of Australia, New Zealand, Tasmania, and Antarctica dating back more than 90 million years to the Cretaceous Period and are virtually identical to those of the Wollemi pine. The Wollemi Pine starts to need copious amounts of water when the flush of growth arrives in the late spring, until then just make sure that the compost is just kept moist.The new growth emerging on my Wollemi Pine is bronze or brown in colour.We assume that because of the extremely cold weather this year that some of the new growth is emerging yellow, bronze or even brown; in the past we have observed that as this growth matures it returns to a green colour. The bark is very distinctive, dark brown, and knobbly, quoted as resembling a popular breakfast cereal. [unreliable source? INSPIRE, NTv2, EPSG, GPS,. Adult Wollemia nobilis trees are up to 40 metres (about 130 feet) tall, frequently becoming multistemmed with age, with dark reddish brown bark characterized by spongy nodules that give it a “bubbly” appearance.
Planting trees is one of the easiest ways to offset your carbon footprint and become carbon neutral.Trees absorb carbon dioxide to produce oxygen and wood. The Wollemi Pine was discovered in August 1994 by David Noble, a NSW National Parks and Wildlife Services Officer who, when trekking and abseiling with friends, noticed the unusual nature of the Pine and took a small fallen branch home for identification. People are urged to not look for the groves, as they might trample young plants.
They are arranged spirally on the shoot but twisted at the base to appear in two or four flattened ranks. By taking this carbon dioxide from the atmosphere, trees clean the air. The Wollemi Pine has been found to be relatively resistant to most diseases. Dubbed the botanical find of the century, the Wollemi Pine is now the focus of extensive research to conserve this ancient species.
Another location to view the Wollemi Pine is Taronga Zoo. Some of the trees date back 400 years…
 After it was discovered that the trees could be successfully cloned, new trees were potted up in the Botanic Gardens of Sydney and Mount Annan. These can then be sown on top of seed raising mix and watered. These spots or sap blisters are a fairly common occurrence and are completely natural; they are not evidence of a disease or insect attack and rarely affect the overall health of the tree.It is assumed that they are a part of the same mechanism that helps the tree to produce the 'polar cap' but rather than sending the exudates to the growing tip they find their way out through the stomata in the leaves. If the branch is dead it is best to remove it, for large diameter stems and branches (greater than 5cm) use sterile, sharp pruning equipment to match the size of the stem or branch being pruned. Another unique feature is its pattern of branching with the mature foliage having two ranks of leaves along the branches. Seedlings from the park were taken from the park and sold commercially. Incorporate some slow release fertiliser into the compost along with the sachet of RootGrow that is supplied with the tree.  An early study of the rbcL gene sequence places Wollemia in the basal position of the Araucariaceae and as the sister group to Agathis and Araucaria. Wollemi pine, (Wollemia nobilis), rare evergreen tree, a member of the conifer family Araucariaceae and the only member of its genus.
The pendulous slender microsporangiate cones can become 10 cm (4 inches) long and have numerous tiny pollen-bearing microsporophylls.

Always ensure controlled release fertiliser is evenly placed around the tree and not in contact with the stem.It is important in a severe case of tipping as in picture B to Re-pot either into a bigger pot or one of the same size. , In November 2005, wild-growing trees were found to be infected with Phytophthora cinnamomi. The majority of seeds that fall from the cone are not viable so need to be sorted to retain the plump and dark ones.
He was advised against this as it was seen as a dying job in Britain and instead studied for his National Certificate in Horticulture (arb) where he qualified with the best practical marks in his year.
The more massive globose megasporophylls can reach 10–12 cm (4–4.7 inches) in diameter and appear somewhat spiny because the cone scales have outwardly curved elongate tips. Tony has also made numerous television and radio appearances and now has his own series that will air on BBC Two in Autumn 2006, entitled The Trees that made Britain.Tony recently ran in the Treeathlon to support the Trees for Cities campaign for more trees in urban areas in the UK, and states looking at trees anywhere in the world as one of his hobbies, something that he regularly gets to indulge by working at Kew Gardens. Tony then moved to Hamburg as the Germans were pioneers in arboriculture in Europe at that time. , Fossils indicate that the lineage leading to modern Agathis and Wollemia evolved from the common ancestor with Araucaria in the Early Cretaceous in southern Gondwana within climates experiencing cool moist conditions and a strong photoperiod regime. They disintegrate at maturity to release the seeds which are small and brown, thin and papery with a wing around the edge to aid wind-dispersal.
The Royal Botanic Gardens in Sydney have published information on how to grow Wollemi Pines from seed which has been harvested from helicopters from the forest trees.
