The first truffles can be produced from 4 or 5 years after planting for some species e. It has been the Holly Oak, Q. Some early producing species will produce for up to 20 years, yet later producers are said to still keep going after 50 years.
The key is to look for grass dying off underneath the tree, leaving an area brownish in colour and rough on the surface — called brulee, like the dessert, it has a burnt appearance.
This indicates fungal activity for the truffle as it kills off other organisms around it. Electric fencing was also needed at the farm to keep out marauding foxes, rabbits and kangaroos and I guess wild pigs! Once exposed, the developing truffle is destroyed so control is critical.
Beetles, weevils, snails and slugs also need to be controlled for successful production. Does it all sound a bit too hard? I have inherited a property with hazlenut trees which have been innoculated with the truffle spore. I am not sure why because the property just up the road has had great success — the only difference is that they have Oak trees. Our property is in a cool climate zone in Australia with great volcanic soil with good rainfall. I have measured the soil PH and it shows 6 — 5.
What else do I need to check? How much lime do I need per square metre? Do the trees after 10 years of not producing need to be re-innoculated? Look forward to your advice. Kind regards, Sandy. There may be instances where you want to kill all fungi, but forests rely on fungi to access nutrients. Fungi turn tough leaves and cellulose wood into readily available nutrients. Local fungi is best adapted to compete. If you kill all local fungi with a product, you have the potential for foreign fungi to get established…and kill the UK woodlands and forests, the food for plants, butterflies etc…..
A lady had truffles and many species of mushrooms under a yr old oak many lovely in recipes! On the other hand many nurseries use mycelium from one or other fungi to grow plants whips faster…but then these tiny trees even if from local source or DNA, they are ruined for the local mycelium, and beautiful mushrooms…that is boletus, truffles etc.
I am glad to see that The Forestry Commission which looks after many hectares of woodlands and forestry did not seem to be interested. It is reassuring…. Hi just to add to what French Marie said, I produce a liquid organic fertiliser which is also a great fungicide which I have offered the forestry commission and other organisations on a number of occasions but they dont seem to interested.
Please beware that there are 33 species of truffles, and I have collected 13 species in the UK. If you want to buy truffles to eat, that may be fine to buy from outside the country, but for using as inoculum, throwing the debris on any land, you risk damaging the environment, import damaging bacteria, insect larva, and fungi species, to the UK. Northern Africa harvests mostly terfez, which are not truffles. They keep wanting to put them in the same categories but scientifically and culinarilly they are not.
They are hypogeneous fungi below soil level fungi eaten like potatoes. I do not recognise these dates as dates for harvesting species of truffles. See what has happened to the Dutch elm disease, oak die back disease rhododendrons , ash currently….
The ratio of Calcium to Magnesium is particularly important. It is Magnesium that appears to regulate the symbiotic trigger in these fungi a requirement to establish the fruiting body; this has been known for some time.
There are however other mechanisms of this symbiotic relationship that are more poorly understood that limit the scope of the truffles growing in Southern Europe. A new book on encouraging biodiversity in your woodland. Available free here ». French Marie 1 September, Has anyone ever heard of decent good truffles being found in Cornwall?
You will get the second answer when you respond to your locality of the woodlands of course. French Marie 4 August, French Marie 5 June, I am the secretary of a group of mainly European scientists, but some international ones also. French Marie 28 May, Hello French Marie, Do you think there will be truffles in west Africa.
Gorgibaby 26 May, Guy Kiddle 21 June, Andrea, The first truffles are noted in June on the surface of the soil. French Marie 21 June, Hi Andrea, Sounds like a lucky find this time of year, particularly if you are posting from the UK. Would also be great if Rob could get in contact with me at the same address? Guy Kiddle 19 June, Andrea Phillips 19 June, Vicky 29 May, Peter Burton 19 March, Peter, You have to be fully aware of what any introduced product does.
French Marie 19 March, Peter Burton 18 March, Your take, do you give back? Jamie 14 January, Philip 25 December, French Marie 18 November, Guy Kiddle 23 September, Truffles require a good downpour in spring and autumn for the truffles to form and to grow to maturity.
If your area's climate does not provide this, supplemental irrigation will do the trick. Planting out. We like to plant between and trees per hectare depending on the irrigation design and layout. More trees will work as you will get mycelium coverage reaching from tree to tree earlier. We are emulating a European woodland at the edge of the forest where sunlight filters down to the ground. If the soil was properly prepared at the liming stage, little will have to be done for some years depending on local conditions.
Our forester will visit on a thereafter to advise on tree-pruning and disease control. Soil and leaf testing will show trace element shortages and corrective steps will be advised.
As we do not want to compact the soil in the orchard in any way, only a very light tractor should be used to mow and annually aerate the topsoil with a shallow-tined implement. At least once a year, one of our team of experts will visit the orchard to identify the mycorrhizal progress.
The team will visit the orchard at the start of harvest time in winter to help identify the onset of production. Therafter each farmer is expected to manage harvesting with thier own dogs. Harvests are graded and marketed through Woodford Truffles.
Site Establishment Your site selection is the second most important step toward successful truffle production, a well drained soil is very important.
Soil preparation Your soil will need to be comprehensively tested to measure its natural pH, buffering capacity, organic matter content and the availability of plant nutrients. Irrigation As the melanosporum truffle originates from the northern hemisphere and grows with the natural rainfall there, we need to emulate these conditions if we want to be successfully cultivating it in the Southern Hemisphere.
