The Geelong Botanic Gardens are preparing to mark 175 years since opening, with the historic gardens continuing to serve as an important community, educational and horticultural space in the Victorian city.

The gardens were established in 1851 and have developed alongside Geelong over almost two centuries. Today, the site contains a significant collection of plants and mature trees, including specimens that have been part of the gardens for more than a century. The gardens attract hundreds of thousands of visitors and remain a popular place for people to walk, relax and connect with nature.

Behind the gardens' appearance is a large amount of ongoing work by horticultural staff and volunteers. Members of the Friends of the Geelong Botanic Gardens help maintain designated sections of the gardens, undertaking tasks such as weeding, pruning, fertilising and mulching.

Some volunteers have maintained connections with the gardens for decades. Their work helps preserve historic plantings while also supporting the gardens' ongoing role as a public space.

Garden supervisor Sheree Parker said caring for an historic botanical collection carries a responsibility to ensure it remains available for future generations. Staff use modern equipment, automated irrigation and collection databases alongside traditional horticultural methods to maintain the gardens.

The gardens' collection database is also being made increasingly accessible to the public. Information about individual plants, including their history and age, can help visitors better understand the significance of the living collection.

The gardens have also become an important location for environmental education. Their education programs work with local schools and The Gordon to introduce young people to plant science, sustainability and biodiversity. These programs are designed to help younger generations understand the importance of protecting natural environments.

The gardens' historic trees are another significant part of the site. Some trees across the gardens and neighbouring Eastern Park are listed on the National Trust Register, reflecting their cultural and horticultural importance.

Weather remains one of the practical challenges facing the gardens. Excessive rainfall can affect some plants by creating conditions that damage root systems, while changing weather patterns require staff to carefully manage irrigation and plant health.

The gardens have also attracted national and international attention in recent years. A corpse flower bloom in 2024 drew more than 20,000 visitors and generated hundreds of thousands of livestream views, demonstrating the ability of the historic site to attract large audiences through unusual horticultural events.

The 175th anniversary will be marked with a free community celebration on Saturday, October 3. The event will include guided walks, plant sales, heritage talks, cultural activities, workshops, exhibitions, children's entertainment and food vendors. The City of Greater Geelong has confirmed the event will run from 10am to 3pm.

The anniversary provides an opportunity to recognise both the gardens' long history and the people who continue to maintain them.

For Geelong residents, the gardens remain more than a historic collection of plants. They are a place used for recreation, education, community activities and public events, while the volunteers and horticultural teams continue working to ensure the living collection survives for future generations.

As the gardens approach their 175th anniversary, their history and continued community use highlight how a public green space can remain relevant while preserving its original heritage.
