Botanic Gardens Week is coming up 🌿

This year’s theme, Where Your Health Grows, celebrates the powerful role botanic gardens play in supporting wellbeing. In a busy world full of noise and distraction, the Australian National Botanic Gardens offers a restorative space — somewhere to slow down, move gently, reconnect with nature, and share moments with others.

🌱 Botanic Gardens Week is an annual celebration highlighting how botanic gardens strengthen mental, physical and social wellbeing, while deepening our connection to the natural world. From peaceful paths and native plants to birds, fresh air and quiet places to pause — there’s something here for everyone to rest, reflect and revive.

Scientists confirmed that trees in forests actively share sugars, water, and nutrients through underground fungal networks — supporting weaker and younger trees during stress periods in a biological cooperation system operating entirely beneath the forest floor.

Researchers at the University of British Columbia mapped mycorrhizal fungal networks connecting 300-year-old Douglas fir trees across 25 hectares of old-growth forest in British Columbia. Carbon tracer experiments confirmed that sugars produced by large hub trees traveled through fungal filaments to shaded seedlings receiving insufficient sunlight for independent survival. Seedlings receiving underground support showed 25 percent higher survival rates during summer drought compared to seedlings with severed fungal connections.

The largest hub trees maintain connections to hundreds of neighboring trees simultaneously, prioritizing resource flow toward genetically related seedlings during scarcity periods. This discovery fundamentally changes how scientists understand forest resilience, suggesting forests function as interconnected communities rather than simple collections of competing individual organisms. Future forest management will need to account for these underground communication systems in conservation planning.
