Pollination and
Fertilization 101
![Page 13: Pollinators, Pollination, Fertilization, and More…eaglepubliclibrary.org/wp-content/uploads/sites/45/2020/04/Pollinators... · What is Pollination? • The transfer of pollen from](https://reader033.fdocuments.net/reader033/viewer/2022042812/5facb9711bb5aa5d6c676d52/html5/thumbnails/13.jpg)
What is Pollination?
• The transfer of pollen from a male part of
a plant to a female part of a plant
• Later enabling fertilization and the
production of seeds.
• This usually happens by an animal, insect
or wind.
![Page 14: Pollinators, Pollination, Fertilization, and More…eaglepubliclibrary.org/wp-content/uploads/sites/45/2020/04/Pollinators... · What is Pollination? • The transfer of pollen from](https://reader033.fdocuments.net/reader033/viewer/2022042812/5facb9711bb5aa5d6c676d52/html5/thumbnails/14.jpg)
What is Fertilization?• Merging of the male and
female genes to create seeds,
fruit etc.

Not all plants produce flowers with both the male and female parts. Those are noted as imperfect. Plants that produce separate male and female flowers on the same plant are called monoecious (men-ee-cious) (Latin meaning “one house”). Examples of this type of arrangement are cucumbers., pumpkins, corn, and European white birch.
Other species may have separate male and female plants with flower of only one sex on any plant. This is called dioecious (die-ee-cious) (again, Latin meaning “two houses). One example of this is holly. Only the female plant will produce berries and a male plant is close by to supply the pollen. Other examples of this type of arrangement is asparagus, spinach, and Japanese yew.

Attracting Pollinators
in the Garden
![Page 20: Pollinators, Pollination, Fertilization, and More…eaglepubliclibrary.org/wp-content/uploads/sites/45/2020/04/Pollinators... · What is Pollination? • The transfer of pollen from](https://reader033.fdocuments.net/reader033/viewer/2022042812/5facb9711bb5aa5d6c676d52/html5/thumbnails/20.jpg)
As a general rule….
• Plants that require pollinators usually have
large and/or bright/showy petals and
flowers
• Wind-pollinated plants tend to have
inconspicuous flowers

Tips for creating a pollinator habitat
• Plant your garden so something is always
flowering from early spring into late fall.
• Crocuses, tulips, etc. can start their food
supply in the spring
![Page 23: Pollinators, Pollination, Fertilization, and More…eaglepubliclibrary.org/wp-content/uploads/sites/45/2020/04/Pollinators... · What is Pollination? • The transfer of pollen from](https://reader033.fdocuments.net/reader033/viewer/2022042812/5facb9711bb5aa5d6c676d52/html5/thumbnails/23.jpg)
Tips for creating a pollinator habitat
• Also, some of our native bee pollinators need
a place to call home.
• In the fall, limit fall cleanup to establish
a habit where they can overwinter by
leaving some leaves on the ground and
not cutting your herbaceous perennials
back.
• Leave a small bare area; they can nest in
the ground.
