Decorah Envirothon Introduction to pollinator gardens

Introduction to Pollinator Gardens

Why use native plants? Adapted to local environment—weather, pests, soils, etc. (use local sources) Useful for native animals—food and shelter Won’t become invasive (some could be aggressive)

Good non-native plants: early color in the spring, complement for prairie yellows, but choose wisely!

Planning: goals, site evaluation, and research

Common goals: beauty, wildlife benefits, open space or visual barrier, etc.

Site evaluation: slope, aspect, moisture & drainage, soil, shade, and adjacent/competing vegetationBuilt environment: power lines, pavement/road, foundation, septic system, underground utilitiesOther considerations: maintenance needs, neighbors & visibility, potential deer & rabbit problems, etc.

Honeybees are arguably the most beneficial bugs in the world.

We know they pollinate most of our beautiful wild and garden flowers.

Honeybees are also the main pollinator for many crops we grow for food.

This apple orchard blooming in April needs to be visited by bees before any fruit can form.

Red ripe apples in autumn, thanks to the work of busy honeybees.

Honeybees get a reward, in the form of nectar, for that work.

Honeybees turn that nectar into honey, which we can siphon off a sample from their hives, for a real sweet treat.

Sulphur butterflies congregate along roadsides in late summer, especially beside puddles after a rain.

Cabbage white – no ring on hindwing. Cabbage whites can be found flying around from April to October.

Cabbage whites may be the most common butterflies we see around the yard, and especially the garden.

Where to find the cabbage white

Not what you want to see on your cabbage plants.

Cabbage white caterpillars aren’t fussy, feasting as well on plants in the mustard family.

Butterflies love native flowers like showy coneflower.

Grow as many different kinds as you can around the garden or out in the back yard.
