How to Sow Seeds in Winter

Make your own miniature greenhouse from recyclables and get a jump on spring by sowing winter seeds.

You will need

  • Knife or scissors
  • Gal. milk jug
  • Potting soil
  • Half-hardy annual and perennial seeds
  • Clear packing tape
  • Liquid fertilizer
  • Garden

Step 1 Cut the jug Cut the jug horizontally with the knife or scissors, leaving a small attached piece that acts as a hinge where the handle is connected. Poke several holes in the bottom for drainage, around the top for air, and one in each side.

Step 2 Fill with soil Fill the carton with 3 to 4 inches of potting soil. Add water until the soil is moist.

Step 3 Plant seeds Plant half-hardy annual and perennial seeds according to package instructions and then tape the cut you made around the jug with the packing tape.

Step 4 Place in sun Place the jug in a sunny area outside next to your house. Water it only when needed to maintain soil moisture.

Step 5 Fertilize Fertilize with a very diluted liquid fertilizer if sprouts turn yellow or light green, which indicates a lack of nutrients.

Step 6 Plant after frost Separate the individual plants and plant them in your garden after the last frost of the year.
