Weeds

Weeds are just plants that are growing in the wrong place. They could be dandelions, grass, vines, shrubs, and even trees.  Below you will find a garden guide to weeds in general, and then separate fact sheets for Dandelions, and for Quackgrass.

Removing Invasive Weeds Without Toxic Chemicals
Winter is the best time to remove invasive weeds from your property - while the ground is soft.

How can you get rid of Himalayan blackberries and English ivy without using toxic chemicals that can get into our salmon streams and Puget Sound? This video covers tools and techniques to make these jobs easier, when restoring a landscape taken over by invasive weeds. Along the way, it covers weed and native plant identification, the importance of replacing the weeds with other (ideally native) plants, and why English Ivy is one of the worst invasive plants in Western Washington. This project is funded by the King County Wastewater Treatment Division, in partnership with the Vashon Nature Center.

Sheet Mulching - Weed Control with No Chemicals

Sheet mulching is a way to keep your shrub and perennial borders almost weed-free, and is a low work, inexpensive way to convert a lawn area into vegetable or flower gardens.  Here is a guide to how to do it. This guide was prepared for residents of Vashon Island, Washington, but much of the information will be useful no matter where you live.  Click here to see and download the pdf file.


We also have created 3 short videos of the sheet mulching process:


Part 1 covers the preparation of the sheet mulching area and placing cardboard.

Part 2 covers tips on working with large piles of wood chips and loading wheelbarrows efficiently. https://www.youtube.com/watch?v=QX-FunfK5uY


Part 3 covers tips on spreading the wood chips, and when you would use compost instead of wood chips. https://www.youtube.com/watch?v=W9KjrhraHlY

Funding for the Sheet Mulching videos was provided by the Vashon-Maury Island Groundwater Protection Committee, with a generous donation of his time and talents for the videotaping by West McLean, founder of the Vashon Remembrance Project.
