Edinburgh botanic garden replaces 5,750 glass panes to shield plants from winter storms

The Royal Botanic Garden Edinburgh has spent five years replacing its greenhouse glazing with 5,750 panels of toughened glass to reduce the risk of falling panes during Scotland’s winter storms, according to reporting by the Guardian.

Staff are working to protect large numbers of tropical ferns, cycads and rare alpine heathers housed in the garden’s glasshouses. The new panes are intended to limit the danger posed when high winds cause panels to break and fall onto the greenhouse floors, a hazard that has previously forced closures and damaged plants.

Why the upgrade was needed

The garden’s glasshouses are exposed to strong autumn and winter gales that can dislodge panels. On the windiest days the risk has been severe enough that staff will not enter the glasshouses when winds exceed 30mph, the Guardian reports. Falling glass has in the past caused extensive plant damage, described in coverage as “decapitated” plant specimens.

Garden managers say the toughened glass is a major step toward reducing that risk, but they also signal the work is not yet finished. According to the Guardian, further measures are still required to fully secure the collection and to prevent future damage during storms.

What this means for the collection

The replacement of 5,750 panes aims to improve safety for both people and plants and to reduce interruptions to curatorial work caused by storm-related closures. The project is presented as the culmination of a five-year effort to fortify the garden’s infrastructure against increasingly severe weather in Scotland’s autumn and winter months.

Reporting notes that while the new panes increase resilience, the garden continues to assess and implement additional protections to safeguard its diverse collection of species.
