If you want to grow the plant from seeds, then you must buy good quality seeds from a trusted company. Here are the steps for planting seeds:
Select an appropriate pot based on the type of the plant.
Choose nutrient enriched potting soil which supports the plant growth.
Sow the seeds up to 1.5 inches deep in the soil and keep the pot in a place, where it gets at least 2 to 3 hours of indirect sunlight. Once the plant starts growing, you can keep the plant pot in your balcony or backyard.
