July 2024 – Aberystwyth Demonstrator Hub Update
At the Aberystwyth Demonstrator Hub, crops show steady progress with seasonal changes. SRF species, including alder and black locust, are dropping leaves, with Eucalyptus demonstrating significant active growth. Miscanthus giganteus is thriving at around 2m tall, with some flowering, while grass weeds in Miscanthus Athena plots remain manageable. SRC willow and variety trials display mixed stages of leaf loss and limited signs of insect damage. Maintenance, such as mowing to control broadleaf weeds in reed canary grass and switchgrass plots, is ongoing to support crop health.
