Push from the bottom of the module up to ease the compost and plants out of the module.

It is best to plant Spinach in a place where it will get some shade to stop it ‘running to seed' which means it will grow too quickly and produce seeds before you have a chance to harvest the leaves.
Make a hole big enough to plant the spinach plant in your container.
Place the spinach plant into the hole and fill the hole with soil. Press the soil down around the plant.
You can fit about four spinach plants 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.
