Going Nutty for Native Plants!

Many of our native plants have very ornamental branch structures, flowers, leaves, and berries, making them ideal for incorporating into an established landscape or using as the foundation for a new garden. Native plants are already adapted to our wet winter/dry summer climate and acidic soils, and do not require much fertilizer or supplemental water once established. Adding native plants to your landscape is a great way to increase its year-round beauty without increasing the amount of time and resources you use to maintain it.

This class will provide you with tips for determining which native plants will fit best into your landscape, which plants will also attract birds and beneficial insects to provide natural pest control in your garden, and planting methods for bare-root or containerized natives.

 

The class will include an indoor presentation with live plants and samples, plus an outdoor tour of mature native plants at the Center for Urban Horticulture!

Picking the Right Plant and Place

April 17th, 2015 by Sasha McGuire, Education Program Assistant
Which one to get?

Which one to get?

This class is for all those people who go to the nursery or greenhouse, see 50 seemingly identical plants and just throw up their hands. Which one to choose? Aren’t they all the same? Bare root, ball and burlap or container?  And all I need to do at home is just dig a hole and plop it in right?

Or maybe you have purchased plants before, (expensive plants, too!), only to have them mysteriously kick the bucket a year or two later. Find out what could have gone wrong and how to stop it from happening again. (No more wasted $$!)

Emily Bishton will demystify this process. Learn how to pick the best plants from the greenhouse by choosing those with the best root and branch structure, and predicting how they will grow in the future. Once you’ve picked  your perfect plant, find out how to plant, mulch and water it properly. With these tips, your plants will bring you joy and beauty for years to come!

Up By Roots: Healthy Soils and Trees in the Built Environment

September 30th, 2014 by Sasha McGuire, Education Program Assistant

Up by RootsUW Botanic Gardens: Up by Roots - Healthy Soils and Trees in the Built Environment is a one-day workshop on October 15 that highlights the principles of soil science and their use in facilitating the growth of healthy trees and developing water efficient landscapes. Healthy soils absorb and hold water and nutrients needed to grow long-lived trees. These same soils retain runoff and preserve water at the site, reducing the need for irrigation and limiting potential impacts on nearby water sources.

This is a hands-on workshop that includes lectures and field work intended to introduce the underlying scientific principles guiding tree biology and soil-water relations. It is only through a healthy respect of these guiding principles, that one can effectively design, install, and manage soils and trees in the urban landscape.

James Urban, FASLA, ISA is a landscape architect with over 30 years of experience in the field of urban development. This workshop combines Jim Urban’s extensive experience with contributions from local experts to address regulations and conditions specific to our area.

Presentations will be relevant to urban foresters, landscape professionals, consulting arborists, tree care professionals, urban planners, landscape designers, sustainability professionals, landscape architects, municipal managers, land managers, and planners.

LA CES PDH, CPH, ecoPRO, ASCA, APLD, PLANET, ISA credits available.

WHEN: October 15th, 8:15am-4:30pm
WHERE: UW Botanic Gardens – Center for Urban Horticulture, NHS Hall
