The Benefits of Winter Sowing

Winter sown seeds have a higher germination rate and grow to be hardier plants compared to those started indoors. By subjecting them to outdoor conditions like rain, snow, and wind, the seeds only germinate when they are ready, resulting in stronger, more resilient plants.

Moreover, winter sowing saves valuable indoor space, reduces the need for constant care of seedlings, and even promotes recycling by repurposing plastic containers as mini-greenhouses.

When to Winter Sow Flowers

The best flowers to sow in winter are perennials that require cold stratification. For those in Zones 2 through 5, January and February are suitable for sowing such flowers. As for Zones 6 and 7, December is ideal for starting perennials, with late February or early March recommended for hardy annuals and biennials.

How to Sow Seeds in Winter for a Spring Bloom

There are three ways to pre-seed your winter garden:

Tips for Letting Flowers Reseed Naturally

Allow mature perennials, biennials, or annuals to go to seed
Stop deadheading the flowers in early fall
Let nature take its course and watch your garden come to life in spring

Tips for Manually Winter Sowing Flowers

Direct-sow saved or purchased seeds into a prepared garden bed
Introduce freshly harvested seeds into the planting area
Water gently after sowing, before the ground freezes

Sowing Flowers in a Winter Mini Greenhouse

Repurpose one-gallon milk jugs as mini-greenhouses
Use seedling trays with humidity domes for best results
Plant seeds at appropriate depths according to instructions
Ensure containers receive regular moisture and airflow
