Hub Site Update – SRUC Edinburgh – September 2023

September 2023 – Hub Site Update

The SRUC Edinburgh site experienced something of a heatwave at the beginning of September but it turned colder later in the month.

The electric fencing is still to be erected (once the tractor has sprayed the glysophate on the grass demo plots and corridors). Strimming and spraying have been ongoing to control weeds. Eucalyptus & SRF poplar inter-row spraying was carried out on 13th September, the SRF demo plots and SRC Poplar plot are planned for spraying next. The Sida plot will need to be hand rouged (OSR/Charlock).

The Grass Demo plots were glysophate sprayed on 4th September.

Some light deer grazing has been noted in the willow variety trial (but not in SRC willow plot).
