Pruning and it’s Effects on Plants by Robert Tripepi

Have you ever wondered how pruning influences plants? Why does pruning the right way result in beautifully shaped greenery? Why does pruning incorrectly result in poorly shaped and ugly plants? How can you prune to control size and shape while still encouraging your plants to look their best and/or fruit?

Do you want your yard and garden to look like a Home and Garden spread or like someone let several hyped up five year old kids loose in your yard with electric hedge clippers?

Who can answer these questions and more? Dr. Bob Tripepi, that's who. He is a professor of Plant Science at UI. I have known Bob for years and he is the expert in anything with chlorophyll.

Dr. Bob Tripepi will cover reasons for pruning plants, plant responses to pruning, timing of pruning, types of pruning cuts and locations of pruning cuts. All of these topics are related to how pruning can effect plant growth. Proper pruning can reduce plant maintenance needs for various inputs. The presentation will focus on landscape plants but the principles also apply to fruit trees.


Kole Tonnemaker of Tonnemaker Hill Farm in Royal City, WA. will tell you more about organic orchard practices and the philosophy behind it.

The Tonnemakers have been growing fruit since 1967, have been bringing fruit to the Moscow Farmers Market since 1984, and joined the organic program in 1997. As you can imagine, they know a lot about how to grow tree fruit organically!

Integrating beneficials, pollinators, and biocontrols in an organic farmscape.

Brad Jaeckel, farm manager at the WSU Eggert Family Organic Farm in Pullman, will discuss strategies to increase beneficial and pollinator insect species as well as other biocontrols to consider.  The 10 acre WSU Eggert Family Organic Farm produces vegetables, tree fruit, and provides space for research.  Implementing inter-cropped species and perennial habitat for insects  throughout the farmscape are key to increased biodiversity.  Attraction of raptor and native bird species are also encouraged to reduce rodent and insect pressure.   Benefits include increased pollination, reduced insect pests, and reduced rodent populations.  Presentation will include specific examples of plant species, planting techniques, and biocontrol designs.

Brad Jaeckel has managed the WSU Organic Farm since 2005 and also teaches three classes in the Organic and Sustainable Agriculture degree.  He lives in Moscow, ID, where he and his wife operate Orchard Farm.  Kate Jaeckel specializes in natural body care products and grows herbs, botanicals, and cut-flowers for the business and farmer’s market sales.

Coming soon: Ways to Protect Pollinators From Neonicotinoids and Other Pesticides

Background on use of neonicotinoids, environmental impacts and hazards posed by them, and ways to reduce exposure of pollinators to these pesticides

Learn how to protect pollinators from harmful pesticides in this presentation by Tim Hatten.

Did you know that the plants you purchase at commercial nurseries could be sprayed with neonicotinoid insecticides? The spray can last on the plant for several years killing or harming bees and other pollinators.

Tim Hatten discussed the background on use of neonicotinoids, environmental impacts and hazards posed by them, and ways to reduce exposure of pollinators to these pesticides.

The Palouse Pollinator Summit was February 23-24, 2022

We will be putting zoom video of the speakers here.
