Pollinator populations are under real pressure — habitat loss, pesticide exposure, disease, and climate change have all contributed to declines in both managed and wild bee populations. The good news is that individual gardens, collectively, represent a significant and underutilised habitat resource.
Start with an honest assessment of your space
Before buying a single plant, observe your space at different times of day. Note sun exposure (most pollinator plants need 6+ hours of direct sun), soil type (dig down 6 inches and squeeze a handful), existing plants (mature trees provide nesting habitat — don't remove them without considering their wildlife value), and water patterns.
Design for continuous bloom
The single most important design principle: continuous bloom from early spring through late fall. Aim to always have something in flower from March through October.
| Season | Target window | Example plants |
|---|---|---|
| Early spring | March–April | Oregon Grape, Red Flowering Currant, Camas |
| Late spring | May–June | Lupine, Phacelia, Alliums |
| Early summer | June–July | Lavender, Catmint, Echinacea |
| Mid-late summer | July–September | Sunflowers, Agastache, Borage |
| Fall | September–October | Goldenrod, Native Asters, Sedum |
Even five plants — one from each window — create a garden consistently valuable to pollinators across an 8-month season.
Prioritise natives, but don't be rigid
Native plants evolved alongside native pollinators and provide nutritional matches that non-native plants often can't replicate. That said, some non-native plants — borage, lavender, catmint, phacelia — are extraordinarily productive and fill gaps in bloom timing. The goal is a diverse, season-long palette.
What to genuinely avoid: invasive non-natives like English Ivy, butterfly bush (which provides poor nutritional value despite the name), and ornamental plants treated with systemic pesticides.
How to actually convert a lawn area
Sheet mulching: Mow short, lay cardboard over the grass overlapping edges by 6 inches, wet thoroughly, and cover with 4–6 inches of compost. Plant directly through the mulch into the soil below. The cardboard smothers grass without digging and breaks down within a season.
Solarisation: Mow short, water, and cover with clear plastic sheeting for 6–8 weeks in summer. Heat under the plastic kills grass, roots, and weed seeds.
Deep mulch: Lay 8–12 inches of wood chip mulch directly over lawn. Grass dies within a season from lack of light.
Avoid tilling — it disturbs soil structure, kills beneficial organisms, and brings weed seeds to the surface.
Provide nesting habitat, not just flowers
For ground-nesting bees (70% of native bee species): Leave areas of bare, undisturbed soil in sunny spots. Ground-nesting bees need nothing from you except to leave the ground undisturbed.
For cavity-nesting bees: Leave hollow plant stems standing through winter — cut back perennials in spring rather than fall. A mason bee house provides supplemental cavity nesting.
For bumble bees: Undisturbed areas of long grass or leaf litter at garden edges are valuable. Avoid frequent, deep soil disturbance in established beds.
Reduce and eventually eliminate pesticides
Even pesticides marketed as "bee-safe" can harm native bees, especially smaller solitary species. Systemic pesticides persist in pollen and nectar for weeks to months after application.
A practical transition: Year 1 — stop all prophylactic applications. Year 2 — switch to least-harmful targeted interventions. Year 3 — a well-established diverse garden typically has far fewer pest problems as natural predator populations recover.
Starting small and building
A half-whiskey barrel with lavender, borage, and a native aster provides meaningful pollinator habitat on a balcony. A 4x8 raised bed with a deliberately chosen mix of natives and productive non-natives can support remarkable insect diversity.
Start with what you have, plant what you can, and let the garden grow from there.
