For optimal growth, the card/envelope should be planted during April – June in quality soil.
1 – Divide your card in single layers if it exists of multiple parts
2 – Briefly soak the card and its other parts in water
3 – Plant it 3 cm underneath the top soil
4 – Water it daily for at least two weeks to keep the card wet for disintegration
(! Make sure you have water outflow possibilities on the bottom to avoid mold formation)
5 – Enjoy the flowers and feed some bees!
