The card can be planted inside or out doors depending on the temperature & conditions at time of planting.
Take your card & cover with compost, give it a good watering. During the first ten days keep the paper moist at all times as water is necessary for germination to occur.
Once seedlings appear keep the paper moist but be careful not to overwater.
Continue to care for your plants & watch your wildflowers appear.
For best results plant the card within two years.
Seed will still germinate after this time but the germination rate will slow down. Store the card in a cool, dry place until time of planting.
