Once the plant is ready to be planted in a bigger garden, do you remove it from the biodegradable pot or leave it in it?
The seedling pot is biodegradable, so you can also plant the seedling and the pot straight into the soil, as the wood pulp should break down and allow the roots of your seedling to push right through it. To assist the pot breaking down, soak the whole pot thoroughly in either water or a very diluted liquid seedling fertiliser, before planting it in the soil. Make sure the biodegradable pot is completely covered and the top lip is not left sticking out of the ground, as it will act as a moisture wick and draw water away from the roots, where it is needed.
