How to sow in winter

Winter sowing is a method of outdoor sowing in winter. Long term low temperature promotes seed germination of some flowering species, which is called cold stratification. In addition, it is well known that winter sown plants are more resilient and robust than indoor sown seeds.

Here's what you need:

Transparent or translucent plastic containers, such as milk cans or 1-liter soda bottles

A sharp knife

Light commercial potting mixture

First, cut a cut in the middle of the container and around its circumference. Make sure not to cut off the upper half completely! Instead, leave a 1-inch uncut area that can act as a hinge. Punch holes in the bottom of the container to drain.

Fill the container with potted soil to a depth of about 2 to 3 inches. Water the mixture in large quantities to allow excess water to drain. Sow and pat the soil gently to make it firm. Remove the cover and replace the upper half of the container and secure with tape.

Label the container with date and plant variety. Place the container in an outdoor area that is sunny and exposed to rain. However, you need to protect the container from rain and wind.

Pay attention to the soil to ensure it is not too dry; If this is the case, moisten gently. In most cases, seasonal precipitation is sufficient. As the temperature rises, the top is opened during the day and closed at night. Soon you will have fresh seedlings!
