Translated VuB annual reports, covering technical research projects of relevance to hardy nursery stock
AHDB have reached an agreement with Dr Heinrich Lösing of the Trial and Advisory Council (VuB) based in Ellerhoop, Germany, to make recent trials information available to UK growers.
Each annual report summarises activity delivered by VuB on nurseries in the Ellerhoop area over 6 years to 2019.
As the practical issues and problems covered by these trials are similar to those facing both container- and field-grown hardy nursery stock growers in the UK, this translation and sharing of the results should avoid unnecessary duplication of work.
Note some plant protection products mentioned in these reports may not be applicable to use in the UK.
