Local Seeds

Seeds are available online from many seed companies in Canada and beyond, but here in the Kingston area we are fortunate to be able to support several local companies and organizations, which specialize in producing seeds adapted to our regional conditions.

  • Bear Root Gardens: Locally adapted vegetable seeds, all organically grown and packaged on their property in Verona.
  • Kitchen Table Seed House: Produces certified organic vegetable, herb and flower seeds with with a focus on supplying open-pollinated, regionally-adapted, farm selected seed. Located on Wolfe Island, near Kingston, Ont.
  • KASSI (Kingston Area Seed System Initiative): A non-profit, volunteer run organization founded by local farmers, gardeners and  concerned community members who want to ensure seed and food sovereignty in our region. Their seed commons is a living collection of locally adapted open-pollinated seeds, available on a sliding scale donation.

Seeds for cover crops are available TCO Agromart, Selby (north of Napanee), Willows Agriservices, Harrowsmith and through online seed houses.

Native plants

When purchasing new seeds or plants for your garden, consider native species when possible. Avoid invasives, defined as “non-native plants whose introduction or spread negatively impacts native biodiversity, the economy, and/or society including human health.” Invasive plants are sometimes still sold by nurseries, big box stores or even at community plant sales.  

The Ontario Invasive Species Council has produced this handy Grow Me Instead publication to help guide your invasive-free gardening choices.

Ottawa Wildflower Seed Library hosts many pop-up native seed and seedling giveaways through gardening season, as well as doing a mailout of native seeds in the winter.  They don’t have a permanent physical address, but are a key contributor to native plant stocks in our area.

Little Forests Kingston offers a choice of four different “pocket forests” - collections of native trees, shrubs and groundcover plants suitable for planting in small urban areas. Choose a collection for a Food Forest (edible fruits, nuts, berries), Keystone Forest (food and shelter for birds and Lepidoptera), Small Spaces Forest (increase biodiversity in the smallest of spaces) or Wet Forest (absorb rainwater and support pollinators).

The Friends of Lemoine Point manage a Native Plant Nursery at the north end of Lemoine Point to grow their own plant stock for reforestation activities, using seeds and cuttings collected from native trees and shrubs. Trees, shrubs and wildflowers are also available seasonally for sale to the public. (2025 sale date to be announced). Native perennials as well as native shrubs and trees can be also be purchased any Wednesday morning between 9:00 and noon between May and October. 1440 Coverdale Dr. Kingston ON.

Fruit and Nut Trees Nurseries

When buying a fruit tree, ask about the source. Often nurseries and and box stores source their fruit trees from Oregon. These trees may not have the same hardiness as trees grafted and grown in Ontario or Quebec. Nor can they list which root stock the fruit tree is grafted onto. Ideally, choose a fruit tree from a nursery where you can select a root stock best suited to your soil.

The City of Kingston holds a Neighbourhood Tree Planting Program which offers property owners within the City of Kingston an opportunity to purchase trees for a discounted rate to plant on their private property. Acting on the City’s strategic priorities to demonstrate leadership on climate action and to foster healthy citizens and vibrant spaces, the program encourages the community to help grow and preserve Kingston’s tree canopy.  Details of the 2025 program should be available on the city website in March.

Soil testing

Urban gardens that are intended for food production should be assessed for the presence of any soil contaminants that may be present as a result of past site activity.  Toronto Public Health has produced a helpful step-by-step guide to determining the level of soil safety for a proposed urban garden.

From the Group Up: guide for soil testing in urban gardens

There are different types of soil testing:

For mineral/chemical tests: The Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA)  maintains a list of accredited soil testing labs in the province. Refer to company websites for testing parameters, including macronutrients, micronutrients, pH, fertility analysis and soil microbiology.

For the living fraction of the soil, testing for microorganisms (bacteria/fungi, protozoa etc.); also compost quality, plant tissue analysis:
