To encourage maximum growth and flowering, the plant should be exposed to temperatures ranging between 20°C to 23°C during the day and 15°C to 18°C at night.
Soil Requirements
Heliotropium cressoides Franch. grows well in a variety of soil types, including sandy, loamy, or clay soils. The soil must be well-draining and not waterlogged. A soil pH of 6.5 to 7.5 is optimal for the plant's growth. The addition of organic matter such as compost or well-rotted manure can improve the soil's quality and fertility.
Cultivation methods
Heliotropium cressoides Franch. is a drought-tolerant plant that grows well in well-drained soils. It prefers full sun or partial shade, and it is hardy to USDA zones 8-11. The plant can be propagated by seeds or stem cuttings. Seeds should be sown in early spring, while stem cuttings should be taken in late summer.
Watering needs
When it comes to watering Heliotropium cressoides Franch., it is important to avoid overwatering. The plant can tolerate drought, but it needs regular watering during the growing season to promote growth and flowering. Water the plant deeply once a week, but make sure the soil is well-draining.
