Winter sowing is the technique of growing plants from seeds sown in winter to give them a head start in spring. As any gardener who has ever struggled with a self-seeding plant knows, some seeds do very well when left outdoors in the cold all winter. The seeds that does well in this technique are the ones that need to experience cold, damp conditions either because they have hard shells that are softened by the freezing and thawing or because they are triggered by the change in temperature to sprout. This is called stratification.
So, how is “winter sowing” different than “self sowing? Winter sowing essentially provides a mini greenhouse environment to control the germination of seeds within the boundaries of the container it is sowed in. A quick internet search told me that the phrase “winter sowing” is attributed to Trudi Davidoff, a resourceful gardener who had more seeds than indoor space. Ms. Davidoff sows seeds in covered containers (she uses take-out containers with foil bottoms and plastic tops) and then moves the containers outdoors. The containers act as mini greenhouses, allowing the seeds to experience the chill of winter in a controlled environment. When the temperature warms enough, the seeds germinate and start to grow. I learnt about this technique in the last few months and wanted to give it a try. I sowed Tiger Paw Asters, Monarda (Bee Balm), and Lupine seeds. I am eagerly waiting to see if I am successful in this process. I won’t write about the step by step process I followed, instead I am linking the video here:
I will provide an update on this experiment in spring. So make sure to follow me here or in my social media accounts.
