Seed Swaps – Growing Community, One Seed at a Time

Seed swaps have been around for a looooong time. Even indigenous groups and farmers would share seeds to grow their crops or medicinal plants. Today, seed swaps are commonly organized into large events with one of the most popular being “Seedy Saturday” across Canada. The first Seedy Saturday dates back to the early 90’s in Vancouver courtesy of Roy Forster of the Van Dusan Botanical Gardens. 500+ people showed up for it!

What is a Seed Swap?

Seeds swaps provide an opportunity to access locally adapted seeds and build community. 

What to Expect at a Seed Swap?

Seed swaps are so diverse which can seem daunting especially for the beginner gardener! You don’t need to be the elite gardener to attend a seed swap. They can be casual or more structured with organized tables and trading systems. Some seed swaps operate via money over trade. Some are themed for veggies or tubers or even just flowers!

Typically, you’ll bring your own labeled packets of extra seeds to the event, then browse the tables where everyone has laid out their seeds, selecting the varieties you want to grow and taking a packet or two of each, while also leaving behind some of your own seeds for others to choose from; essentially, it’s a “potluck” style where everyone contributes and takes what they want, ensuring a diverse selection of seeds for everyone to try. 

Some seed events will also offer speakers, workshops, exhibitors, and even food trucks!

How to Participate in a Seed Swap

Before attending a seed swap, look it up online and understand the guidelines. Some swaps will allow beginners to take seeds. Some swaps are cash only. Some swaps require specific labelling.

Make sure seeds are viable and properly stored so they can benefit other gardeners. Take only what you’ll plant. Be prepared to chat with other gardeners. it’s best to come in with an open mind to ask questions and receive experience from other gardeners.

Attending Seed Swaps Online in 2025

Yes, virtual seed swaps exist! Many communities now offer online seed exchanges through:

    • Local Facebook gardening groups.
    • Websites like Seed Savers Exchange or local gardening forums.
    • Mail-based swaps where gardeners send seeds to each other.

Of course, you’ll need to understand any restrictions on mailing seeds and knowing there is always a risk of failure in the honour system.

Caution: Do not exceed the recommended amount. Keep out of reach of children and pets.

High Drainage

Moisten Thoroughly before use: (optional) Peat moss can be water-repellent. Before use, thoroughly wet the soil.

Potting:

Use pots with drainage holes to prevent root rot.

Fill the pot with the moistened soil, leaving enough space for the plant's root ball.

Gently place the plant in the pot and fill in around it with more soil.

Firm the soil gently.

Watering:

This is crucial! Water frequently, especially during hot weather.

Check the soil moisture regularly by sticking your finger into the soil.

Water deeply when the top inch of soil feels dry.

Fertilizing:

Since peat moss is low in nutrients, fertilize regularly with a balanced liquid fertilizer.

Consider Amendments:

For plants that prefer more moisture retention, you can add a small amount of coco coir or vermiculite to the mix.

Important Notes:

Overwatering: While frequent watering is necessary, avoid overwatering, which can lead to root rot.

Plant Selection: This type of soil is well-suited for seed starting as well as plants that prefer well-drained conditions, such as cacti, cannabis, succulents, and some tropical plants.

Adjustments: You may need to adjust your watering frequency based on the specific plant and environmental conditions (temperature, humidity, sunlight).

Alberta Blend

Moisten the Peat Moss before use: (optional) Peat moss can be hydrophobic (water-repellent) when dry. Before using it, thoroughly moisten it. You can do this by placing it in a container and adding water, then squeezing out any excess.

Mixing: (optional) Our Private Label Alberta Blend comes ready to use, expertly formulated for your plants, either indoors or outdoors.

If you're using this mix as your own base, combine it with worm castings, volcanic dust, vermiculite, etc. to improve nutrition, drainage and/or aeration.

Potting:

When potting your plants, ensure that the pot has drainage holes.

Fill the pot with the moistened potting mix, leaving enough space for the plant's root ball.

Gently place the plant in the pot and fill in around it with more potting mix.

Lightly firm the soil around the plant leaving ½ inch to an inch of space at the top for watering.

Watering:

Because peat moss retains water, be careful not to overwater.

Allow the top layer of soil to dry out slightly before watering again.

Fertilizing:

Since peat moss is nutrient-poor, you'll need to provide your plants with regular fertilization.

Use the correct fertilizer according to the plant's needs.
