Simple Winter Sowing Instructions
Start in January, when it is cold outside, even if there is snow on the ground.
1. Empty the soil into the milk jug.
2. Add water to moisten the soil.
3. Scatter the seeds on the soil and gently blend the seeds into the soil.
4. Place the jug OUTSIDE in a sunny location, even if the ground is frozen and full of snow.
5. Check jug once every two weeks when the ground is frozen. Add water if it dries out.
6. When the weather warms up, check the jug more frequently, and add water if it begins to dry out.
7. Sprouts will grow anytime after the end of March.
8. After most sprouts have appeared, gradually remove the lid for part of the day, working your way to completely removing the lids within a week or two.
8. After the frost free date (April 15th or so) and when sprouts have their second set of leaves (first true set of leaves), transplant them into the ground. Clumps can be separated and planted apart from one another.
9. Water newly transplanted sprouts each day for the first week, then water as usual.
