How to grow the Sodom Apple from seeds
The seeds should be soaked for 12 to 24 hours before sowing.
The seeds can be sown all year round in a bright and warm location. I sowed them in early January and used a plant light to grow them.

A permeable mix of sand or fine gravel is a good substrate. Standard mixtures for cacti and other succulents can be used. The seeds shown here were sown in a mixture of peat-free potting soil and bird sand.
The seeds of Calotropis procera must be covered with soil. The sowing depth is about one centimeter.
The soil should be kept evenly moist and not allowed to dry out.
At 73 to 82 °F (23 to 28 °C) it took five days for the first seeds to germinate.
Sites with morning, evening and winter sun are ideal for growing. The seedlings can be acclimated to the hot summer sun when they are between five and ten centimeters tall.
