As a planter, you need to understand when the vegetative stage starts. That is the first most crucial thing that you need to understand. Without this, you might start; however, you will not be successful at growing them. The stage starts as soon as a small leaf comes out of the seed. This is called the Cotyledon stage. Then soon after, you will notice that the seedling is growing a bit from the soil. This can take up to 2-3 days. Finally, when the plant has grown to have enough distance from the soil, then it will start having leaves.
