The Spider Plant is very easy to spread. They can be propagated by splitting its main rosette. It is even easier to remove plantlets from the stolons and plant them separately or put them in a glass of water. They will grow roots readily in water but establish faster in soil while still attached to the parent plant. Pinning the plantlet to the soil with a bent paper clip can be helpful. Make sure the soil is damp and well drained. The plantlet can then be removed from the parent plant in 7-10 days.
