This new factsheet will walk you through: How to build the best soil; what time and money you’ll need; easy & productive plants to grow; and how to care for your plants throughout the growing season.
All factsheets are free on our website and onsite thanks to funding provided by the CRD.
*New* Factsheet #19 Bioremediation for Urban Gardeners
September 23, 2020
We are thrilled to announce the launch of our new factsheet: #19Bioremediation for Urban Gardeners, written by soil toxicologist and HCS program creator Danielle Stevenson, as part of our Healing City Soils project!
This factsheet is an introduction to beginner-level phyto (plant) remediation in soils that are contaminated with low-to-moderate levels of heavy metals. By working with native and non-native plants phyto-remediation is a process that slowly extracts heavy metal contaminants from soil. The factsheet is available for free online at our website: https://compost.bc.ca/…/09/19-Bioremediation_no-image.pdf
Bioremediation for Urban Gardeners is the third factsheet in the CEC’s factsheet series all about soil health and best practices if higher-than-normal levels of heavy metals are detected in your soil. If you’re interested in diving in, we recommend that you start with Factsheets #11 and #12, which introduce you to soil contamination and best practices for growing food in urban spaces.

Spring is the perfect time to be thinking about the best ways to conserve water for the dry summer months. To assist you in ideas around how to construct efficient systems that store our abundance of spring and fall rain, the CEC has created a new factsheet that spans a range of rainwater harvesting systems, from cisterns, to rain gardens, to bioswales. #16 Rainwater Harvesting Factsheet
The Healing City Soils project has been completed for 2016! Almost 140 soil samples were tested in Victoria and Esquimalt through this joint project with Royal Roads University and the results made into an interactive map (coming soon!) to inform the community about potential for soil contamination and best practices for growing healthy produce in back and front yards and boulevards.
As well, we are thrilled to announce that two of our new factsheets from the Healing City Soils project are now complete. These factsheets will help urban gardeners learn more about soil contamination and protect their health while growing their own groceries.
Soil Contamination: Whether you are already growing food or would like to begin a garden, it’s a good idea to learn more about your soil so that you can grow food safely. Urban soils are often compacted and nutrient deficient, and can sometimes contain heavy metals and other contaminants as a result of historical industrial activity, past and present land use and proximity to pollution sources (e.g. a major road). Soil contaminants may get into or onto our veggies and fruits and have negative health effects over the long term. Gardeners can take many simple and inexpensive actions to reduce their exposure to urban soil contaminants. Soils can be managed, improved and made healthy again so that you and your garden can thrive. Find the factsheet here.
Best Practices for Healthy Urban Gardens: We recommend that all gardeners follow healthy gardening practices to help reduce exposure to heavy metals and other contaminants. Generally, maintaining a neutral soil pH, adding organic matter and compost to your soil, mulching your garden soil and thoroughly washing your garden produce can reduce your exposure to many soil contaminants so you can enjoy the many health benefits of eating fresh garden-grown fruits and vegetables.

Bokashi is a Japanese term meaning “fermented organic matter”. Different from composting, which is aerobic, it is an anaerobic process that allows a person to deal with a wide variety of food waste on-site. Bokashi harnesses the power of effective microorganisms (EM) dehydrated onto a cereal base to carry out the fermentation process . It is best used as a partner to a compost pile, because you will need a place to compost the ‘spent’ material once it has finished going through the bokashi process. It is a great alternative to the green cone food digester as it breaks down the same types of materials but doesn’t need sunlight or to be buried down 2 feet in your garden work. You can make your own system or purchase a ready-to-use unit.
In general, tumbler composters are in the form of a barrel mounted on a stand so the unit can be turned or “tumbled” around a central axis. They can be mounted horizontally or vertically, both work well. Turning these units easily incorporates air into the material inside the tumbler, which can speed up the decomposition process. It is possible that you may get a finished product faster than with passive backyard composting due to the increased aeration that tumblers make possible. However, beware of manufacturers that say you will have finished compost in three weeks or less – anything that looks finished in this short amount of time will be unstable and need to sit for at least 6-8 weeks longer to cure.
When we built our new greenhouse wanted the plans for this project to be free and readily accessible. As such, this factsheet includes a budget and materials list for the greenhouse, a list of the lessons I learned, and some photos of the building process.
If you’ve popped into our office lately you may have noticed our swanky new factsheets, but we wanted to give an official introduction to them as well!
