Growing conditions
Optimal soil temperature for germination is between 70°F and 90°F.

Well-draining, nutrient-rich soil with a pH between 6.2 and 7.0 is preferred.
Consistent watering is needed, keeping the soil moist but avoiding overwatering.
Regular fertilization every two weeks during the growing season with a balanced, water-soluble fertilizer is beneficial.
Support, such as stakes or cages, may be necessary as plants can grow up to 4 feet tall.
Pruning can encourage bushier growth and improve air circulation.
