Creating a Bee-Friendly Garden in Australia

Gardening is a delightful way to connect with nature, and creating a bee-friendly garden adds an extra layer of purpose to this rewarding hobby. Bees, including native and exotic bees, play a crucial role in the ecology and production of Australian landscapes and farms, ensuring the health of our ecosystems and food supply.

Here’s how you can transform your Australian garden into a haven for these industrious insects.

Understanding the Diversity of Bees

Bees are part of the order Hymenoptera, which also includes wasps and ants. Australia is home to over 1,700 species of native bees, from the small, non-descript black bees to the large carpenter bees. These native species, along with the European honeybee (Apis mellifera), each have unique needs that should be considered when planning your garden.

Overarching Principles of Bee-Friendly Gardening

Creating a bee-friendly garden involves adhering to several key principles:

• Biodiversity: Plant a variety of species to provide a varied diet and cater to different bees.
• Continuous Blooming: Ensure there are flowers blooming throughout the year, with a focus on early spring flowers to build numbers early in the busy season.
• No Pesticides: Avoid using chemical pesticides that can harm bees.
• Natural Habitats: Provide natural nesting sites and shelters. This can include leaving dead wood in trees and shrubs, leaving bare patches of sandy soil, and building a bee hotel.
• Use Organic Mulch: Organic mulch like chunky wood chips can also offer habitats or nesting materials for ground-nesting bees.
• Create Microclimates: Design your garden to include sunny spots, shaded areas, and windbreaks. Different bee species have varying preferences for foraging conditions.
• Avoid Monocultures: Ensure that your garden does not consist of large areas planted with only one type of plant. Diversity in plant species is crucial for attracting and supporting a variety of bee species.
• Water: Provide small dishes with water, or a bird bath (which should have water replaced every few days to prevent mosquito larvae and bird diseases spreading).

Sources of Food

Bees require nectar and pollen from flowers as their primary food sources. To support them, plant native species such as Grevillea spp., Callistemon spp., Westringia spp., and Kangaroo Paw (Anigozanthos).

But don’t neglect the exotic plants, because they’re often just as beneficial for both exotic and native bees, such as Rhaphiolepis spp., Murraya spp., and flowering herbs.

Including flowers of varying shapes, sizes, and colours will attract different bee species. Grouping plants of the same species together can make it easier for bees to forage efficiently, especially with regards to smaller ground-covering flowering plants.

Sources of Water

A reliable water source is essential for bees. Fill shallow dishes with clean water, adding pebbles or floating corks to create safe landing spots for the bees. Regularly change the water to keep it fresh and clean.

Habitat for Different Types of Bees

Different bee species have various nesting habits. Many native Australian bees nest in the ground, so leaving some bare, undisturbed sandy soil in your garden is beneficial. European honeybees typically nest in hives managed by beekeepers, and can become problematic when they become feral.

Installing bee hotels, which are wooden structures with drilled holes, can provide shelter for solitary bees.

On a fundamental level, having dense, biodiverse shrubbery, trees and ground covers with some dead wood, mulch, bare patches of soil, rocks and chairs for them to sun themselves on, and other types of habitat is generally better for an insect-friendly garden as opposed to a simplified landscape without changes in micro climate.

Buzz Pollinators

Certain bees, like the blue-banded bee (Amegilla spp.), are buzz pollinators. They vibrate their flight muscles while clinging to flowers to release pollen. Including plants that benefit from buzz pollination, such as Dianella spp., tomatoes and blueberries, supports these types of bees.

Seasonal Activity of Bees

Bee activity varies with the seasons. Most bee activity occurs during the warmer months of spring and summer when flowers are abundant. While some bees remain active in autumn and winter, their numbers generally decrease. Ensuring winter-flowering plants can provide essential resources during these leaner times.

Plants like Grevillea spp. and Correa spp. will often flower throughout winter and into early spring, providing a crucial resource early in the busy season as many pollinators wake up. Callistemon spp., lilly pillies, kangaroo paws and other arm season flowering plants can overlap with those cool season flowering plants to provide good coverage as the season changes.

Conclusion

By implementing these strategies, you can create a thriving garden that supports both native and introduced bee species. Not only will this enhance the beauty of your outdoor space, but it will also contribute to a healthier ecosystem. Happy gardening!
