Planting for the Future: Winter Sowing in the Columbia Basin

Winter might seem like an unusual time to think about planting, but for native seeds, it’s the perfect time to get started. Many native plants need to go through a period of “cold stratification” which refers to a period of cold temperatures often with alternating freeze-thaw cycles that allow the seeds to germinate in spring when warm weather arrives.

Winter sowing allows the seeds to settle into the soil naturally. The cold temperatures, combined with moisture, weaken the seed coat, enabling water to penetrate and initiate germination. The freeze-thaw cycles of winter also help work the seeds into the soil, creating better seed-to-soil contact.  For many native plants in our region, cold stratification is essential, as it prevents premature sprouting that could leave seedlings vulnerable to frost.

There are many different methods of planting seeds. One popular method is the seed drill. Seed drills are versatile and ideal for both small and large-scale planting projects, especially in areas where consistent seed placement is important. Seed drills allow for precise planting by creating furrows, placing the seeds at the right depth, and covering them with soil.

Another method of planting seeds in the winter is by using a drone. Drone seeding involves using an unmanned aerial vehicle (UAV) equipped with a seed hopper to distribute seeds over large areas. The drone flies along a predetermined path at a consistent speed and altitude, dispersing seeds at a specific rate (pounds per acre). Operators can adjust the flight path, speed, and height using a hand-held controller, allowing for precise control over seed distribution. This method is ideal for covering challenging terrains or large, inaccessible areas quickly and efficiently.


Spring can be a busy time for gardeners and producers. By getting your seeds in the ground during winter, you’re spreading out your workload and giving yourself a head start. As temperatures warm up, your seeds will already be in place and ready to grow. 



Tips & Tricks for Planting in Winter


  • Check the weather! Plant seeds during periods of precipitation. Seeds will stick to wet ground better than dry ground.

  • The ideal timeframe to plant seeds is during the winter months, typically after Halloween and through the end of February.

  • Enhance your seed mixture by combining it with corn, grit, and rice hulls.

  • When broadcasting seed lightly work the ground or use a land roller after seeding for better seed-to-soil contact and better germination rates.

  • Contact your local conservation district for expert guidance on seed selection, planting techniques, and improving soil health.


One of the most important aspects of growing native plants is patience. Native seeds can take longer to germinate and establish than non-native species, but the payoff is well worth the wait. These plants are better adapted to local conditions, provide habitat for wildlife, and contribute to a healthier ecosystem.
