Thriving in a Climate Crisis: Essential Gardening Tips for Today’s Eco-Conscious Green Thumbs

The sun brightened Melbourne’s gardens in May, giving warm-weather plants a boost just when they expected to fade into winter. Basil and roses perked up again, creating a curious scene as nature wrestled with unpredictable weather patterns. In contrast, parts of southern Australia faced dry conditions, increasing fire risks, while areas in New South Wales and Queensland experienced heavy rainfall.

With seasons becoming more erratic due to climate change, gardening techniques also need to adapt. How can plant lovers thrive when old gardening rules seem outdated?

Prof. Angela Moles, a biologist from the University of New South Wales, highlights that Australia is facing diverse changes. “The dry areas are becoming drier, and wet areas wetter,” she notes. This leads to surprising plant behavior: over a third of plants are moving to warmer areas rather than cooler ones, often shifting at an alarming rate of 800 meters per year. Past ice ages show similar plant movements, indicating a world in constant flux.

Plants are not just changing locations; they are also altering growth patterns. Some flower earlier, but their pollinators may not be around yet. This timing mismatch can threaten various species, demonstrating a pressing need to rethink our gardening practices to match this unpredictability.

Clare Hart, director of horticulture at the Royal Botanic Gardens in Melbourne, emphasizes the importance of focusing on adaptation strategies. Since 2016, her team has evaluated plant species for climate risks, aiming for a resilient future. “With temperatures projected to rise by 3°C and rainfall decreasing, we need to look at plants from warmer climates,” she explains.

In 2018, the gardens launched the Climate Change Alliance of Botanic Gardens and developed a useful climate assessment tool. This tool helps gardeners pick tree species suited to changing conditions. The Australian Drylands project at the gardens serves as an experiment to identify native plants that thrive in a warmer, drier climate, supported by traditional knowledge from Indigenous groups.

For local gardeners, here are some practical tips to adapt:

1. Observe Locally: Take walks in your neighborhood to see which plants are thriving. Note where they’re growing, especially any native species, as these will likely do well in your garden.

2. Understand Your Microclimate: Soil, sunlight, and water vary even between neighboring gardens. Knowing these specifics can guide your plant choices.

3. Seek Local Advice: Smaller nurseries or Indigenous plant nurseries provide great insights on what works well locally. Joining community groups can also help you learn about successful plants in nearby natural areas.

4. Protect Young Plants: Young plants need extra care to establish roots. Create a nurturing environment for them to grow strong.

5. Utilize Online Tools: Consider using resources like the Climate Change Alliance’s climate assessment tool or the Atlas of Living Australia to find plants suited to your area. The Bureau of Meteorology offers climate forecasts to help you plan.

The shifting climate poses challenges, but it also presents opportunities to discover resilient plants and adaptive gardening methods. By learning, adapting, and collaborating, gardeners can cultivate thriving green spaces, even in uncertain times.
