Winter Sowing is sowing your seeds in milk jugs or other plastic containers, and using them as mini-greenhouses outside in the middle of winter. Your seeds will germinate when nature tells them it is time! See my website for a free winter sowing schedule printable!
First step is to collect your milk jugs or other plastic containers.
Poke a bunch of holes in the bottom for drainage, and a few holes around the top for extra air circulation.
Make sure to use a soil that drains well. If the soil stays too wet, the seeds may rot.
Plant the seeds into the soil as directed on the package for depth of planting. Spray the surface with water so the top 1" or so of soil is quite damp.
Close the jug and tape the jug closed all the way around. You can leave the plastic cap that came with the milk jug on, until the seeds germinate, then remove.
Set your Winter Sown containers outdoors in a sunny location that will receive rain. Do not put under an eave which might prevent rain from entering into the open top.
Make sure to label your containers so you know what is what.
