Once planted succulent plants take around 4 weeks to root themselves and start to grow.
When succulents are growing they'll start to turn and bend toward the light source and then they will get taller with more space between the leaves.
Make sure the succulent plants are getting plenty of sunlight and enough water to grow although they don't require a whole lot of water.
Succulents only require watering at least once per week which is enough to keep the succulents growing and thriving.
