What Is Winter Sowing?

Winter sowing is a method of seeding and growing plants in containers outdoors during the winter months.

Plus, it’s great for beginner gardeners who may not have access to specialized equipment or greenhouses.

With winter sowing, all you need are some containers (like milk jugs or plastic tubs), soil, and seeds! It’s that easy.

Yarrow is an easy-to-grow perennial flower with ferny foliage and brightly colored flowers that attract butterflies. They also come in more pastel shades.

To winter sow yarrow, start by selecting a container—I recommend using clear or translucent 1-gallon water or milk jugs plastic because they allow light to penetrate through them and will help keep the soil warm as well as maintain humidity levels inside the container.

They are deep enough to put plenty of soil for the roots to have room to grow. I share all about my favorite winter sowing containers here.

the Best Winter Sowing Containers

Now, this can be debatable but I have winter-sown seeds for decades and these work the best for several reasons.

Check out what works and why!

Fill your container with about 2 to 3 inches of damp potting soil, then add your yarrow seeds (the seeds are tiny but seed thinly).

You can see me do it in the video at the end of this post.

Press the seeds firmly into the soil, then close the container and seal it.

Water well by setting the container into a tub of tepid water to absorb it for about an hour.

Finally, place your container outside in an area where it will get rain and snowed on. I like to put mine in one of my raised beds so they won’t get knocked over easily.

Place on soil or on a surface where the drainage holes do not become blocks. When I place mine on my deck I elevate them so they can drain easily.

Winter sowing Yarrow Care

If they aren’t buried under snow visually check your containers through the winter.

Usually, they will get plenty of water if you get rain but if you live in a drought-stricken location then check to see that the containers are moist inside.

You can usually tell if the containers are moist enough if they have some weight to them when you lift or if they are light feeling.

Also, on sunny days condensation will build up inside where the is plenty of moisture in the soil.

If not, place the containers in a tray or tub of water so it can draw up what it needs.

Only leave the containers sitting in the water for about an hour to hydrate then remove and let drain.

Winter-sown Yarrow Seedlings

You will start to see seedlings as your weather warms.

Keep an eye on the moisture and when the sun begins to really heat up open the containers during the day and close them again at night.

Once the seedlings have their true leaves (second set or more) then you may need to feed them with a diluted water-soluble fertilizer.

I prefer this one as it not only feeds the plants but also feeds the soil which is the best way to go about it.

Stop Fertilizing! Do this instead.

If you’re new to gardening, you might think that the key to a thriving garden is to fertilize, fertilize, fertilize. Just stop, Regenerate the Soil instead!.

Planting your Yarrow

Once all danger of frost is passed then it is safe to transplant into your garden beds or containers.
