When the plants are about 8cm high they are ready for planting outside.
Take them outside and water them well.
Push from the bottom of the module up to ease the compost and plants out of the module.
You should see the roots of the plant holding the compost together.
Make a hole big enough to plant the pea plant in your container.
Place the pea plant into the hole and fill the hole with soil. Press the soil down around the plant.
You can fit about four pea plants and sticks in a 5 litre pot. If the pot is bigger you can fit more plants in as long as there is about 10cm between each plant.
