Place the seeds into a pot with rich in nutrients soil. Plant them 1-1,5cm deep. Water the soil to keep moist at all times. Do not overwater. Keep the pot at a temperature of 15+ degrees average. Once the the tree begins to grow it will need as much sun as possible. (when there is an intense heat wave it is best to keep at a shadowy place). You can start planting indoors near a window until it begins to grow. Jacaranda blossoms every spring and summer. Spray water on its leafs 2 times per week to keep moist.
