Horticulture Corner: Supporting Pollinators in the Garden
Bees, butterflies, and many other insects play an essential role as pollinators in natural ecosystems and cultivated landscapes. They support the production of many crops, including those commonly grown in home gardens. Creating and maintaining pollinator-friendly spaces is one practical way to support garden health and biodiversity.
If you are interested in attracting beneficial insects and pollinators to your garden landscape, the following tips and resources can help you get started:
- Identify and conserve the pollinator habitats you have around the garden.
- Identify the plants you already have and note when they bloom; this will help to identify gaps throughout the flowering season and help to decide where to add flowering plants so that pollinators have food throughout the growing season.
- Conserve existing pollinators' habitats such as untilled, partially bare ground and hollow-stemmed plants for nesting sites and untilled areas with perennial vegetation cover for over wintering sites.
- Include native plant species where possible; they are well suited to local pollinators and growing conditions and will help to increase overlap in blooming times. Plant native species in clumps of 3-8 plants to mimic natural pollinator habitat.
- Provide habitat features such as undisturbed soil, leaf litter, and pesticide-free areas to help support pollinator populations. Some native bee species tunnel into soft wood and utilize beetle galleries for nesting sites. Bumble bee boxes and a branch pile can provide protective cavities for bees to nest and over winter.
