The seeds must be moved away from the parent plant to prevent overcrowding. If too many plants grow in the same area, they may not get all the light and water they need to make their food.
To be able to germinate, the seeds need warmth, air and water. Seeds do not need light to germinate as they have their own food store.
Germination is when seeds start to grow. A seed will germinate when the environment is just right.
