September 2024 – Edinburgh Demonstrator Hub Update
Progress at the Boghall Biomass Connect site in September showcased healthy growth across all varieties, with regular interrow mowing conducted to support field maintenance. The SRF alder and poplar are growing well, despite some rust and insect presence, while Eucalyptus and black Locust generally show good health with minimal damage from pests. Miscanthus varieties are thriving with little disease or vertebrate impact, and although willow showed signs of aphid and beetle activity, it continues to grow robustly.
