Gardening for Pollinators - City of Kamloops

Planting for pollinatorsAttract bees by:• Choosing open flowerswith packed clusters of tinyflowers,• Planting blue, purple, whiteand yellow flowers.Attract pollinating flies such aslacewings & syrphid flies by:• Choosing open flowerswith packed clusters of tinyflowers,• Planting white and yellowflowers.Attract butterflies & day flyingmoths by:• Choosing open or deeperflowers to accommodatetheir feeding habits,• Choosing plants that aresuited as hosts for theircaterpillar stage,• Planting blue, violet, andred flowers.Gardening forpollinatorsWhat are pollinators? They are insects that transferpollen from plant to plant. Pollination is essential forfruit and seed production. Pollinators include avariety of bees, both native (such as bumble bees,mason, leafcutter and sweat bees) and non-nativehoney bees, as well as flies, moths, butterflies, andsome beetles.A note about native bees: There are well over 400species of native bees in BC. Native bees are mostlysolitary. They don’t form hives. Bumblebees formsmall nests, but over 70% of native bees spend mostof their lives underground in tunnels. Other nativebees live in cavities of dead wood or pithy stems.Unlike honey bees, native bees collect mostly pollenand do not produce surplus honey. Except forbumble bees, native bees don’t sting. They have ashort life span (often only 2-3 weeks) and have ashort foraging range of only 100 – 200 metres fromtheir nesting sites. Honey bees are not native toCanada.Threats to pollinators: Urban sprawl, industrialagriculture and landscaping practices lead to habitatloss and loss of plants used by pollinators for forage.Pesticide use kills beneficial insects as well astargeted insects. Honey bees are threatened byprotozoa and mites.• Native flowers, abundant in nectar and pollen.Exotics, especially double flowers and newcultivars tend to have less nectar and pollen.• Heirloom varieties that are rich in nectar andpollen,• Clumps or swaths of each flower species thatattract the attention of pollinators,• Shrubs and trees such as apple, dogwood, andnative willow (avoid weeping willow) that providepollen and nectar in the spring.Enhance pollinator habitat by:• Offering water to pollinators in a shallow dish orbirdbath,• Providing a muddy spot that supplies nutrientsto butterflies and nesting materials for some bees,• Allowing a corner of your yard to go wild withgrasses, weeds, wildflowers, logs and brush thatprovides food, nesting sites, shelter and overwinteringsites,• Leaving areas in your yard mulch free for groundnesting bees,• Allowing leaf litter to remain in your garden asover-wintering sites for bumble bees.Design: Mader & Assoc.Attract night flying moths by:• Choosing deep and openflowers with a strong, sweetscent,• Planting white, cream orpale green flowers that arevisible at night.Attract pollinating beetles by:• Choosing wide open bowlshaped flowers.Specific suggestions areprovided in a chart on the nextpage.Supporting bees andbeneficial insects...why should we care?The work of pollinators benefits us every day,whether it is the food we eat, the cotton t-shirt wewear, or the beautiful annuals in our gardens. Manyinsects that feed on nectar or pollen also providepest control in their larval and/or adult stages.What can we do to help pollinators?Supply plant diversity by choosing:• A variety of flowers that are in bloom at any timeduring the spring, summer and fall,• A variety of colours,• Flowers with different shapes. Pollinators comein many sizes and with different mechanisms forpollinating.Avoid pesticides, insecticides, herbicides,fungicides, etc.• Pesticides may kill beneficial insects as well astargeted insects.• ‘Organic’ and lower-risk pesticides may also killbeneficial insects.• Reconsider aesthetic standards to allow for somepests. (e.g. The presence of aphids is not alwaysa problem. Clover can be beneficial for your lawn.)syrphid fly native bumble bee ground dwelling native bee honey bee
