The National Geographic have produced an excellent article focusing on a recent study into rainfall levels and how these effect truffle harvests; it’s particularly important as climate change is dramatically affecting the truffle industry.
We’re often asked how important rainfall levels are for truffle cultivation and whether irrigation is required, both for the truffle trees and for the truffles themselves. We’ve had a good understanding of this for many years and know that both trees and truffles like a moderate amount of rainfall with a disbursement across the year. The climate in the UK, Ireland and across most of mid and eastern Europe is ideal for good tree and truffle growth and additional irrigation isn’t typically required on truffle plantations.
However, new research published by Prof. Ulf Büntgen of Cambridge University is revealing that the timing of when rainfall occurs in a particular year is also a key factor in when and how many truffles can be harvested the following year.
