Heliotropium parviflorum L. commonly grows best in full sun. Therefore, it is recommended that it is grown in an area that receives continuous sunlight for a minimum of six hours daily. When heliotropium grows in semi-shaded areas, it has a slower growth rate, smaller leaves, and can exhibit stunting.
Temperature Requirements
Heliotropium parviflorum L. typically grows best in moderate temperatures, between 10-25°C (50-77°F).
Extreme hot temperatures may lead to drying out the soil and premature death. On the other hand, heliotropium is susceptible to frost and cannot endure temperatures below 0°C(32°F). Thus, it is necessary to move potted plants into warmer indoor temperatures or plant them outside during optimal temperature periods.
Soil Requirements
The soil type for planting Heliotropium parviflorum L. should consist of soil with good drainage and organic matter. Additionally, soil pH should be slightly below to neutral, i.e., between 6.0 and 7.5, which can be achieved by the incorporation of acidic fertilizers that can help acidify alkaline soils.
It is also essential to ensure that the soil's water-holding capacity is high, and it must be kept moist. If the soil moisture is low, it may lead to wilting or stunted plant growth. Heliotropium parviflorum L does not tolerate waterlogged conditions, which can cause root rot that may lead to plant death.
Cultivation Methods for Heliotropium parviflorum L.
Heliotropium parviflorum L. commonly known as small-flowered heliotrope or baby heliotrope is a small, drought-resistant shrub, native to North America, which is suitable for growing in gardens, containers, and indoors.
The plant requires well-draining soil rich in organic matter and thrives in full sun to partial shade. To grow it outdoors, it is preferable to start with well-prepared soil that is slightly acidic to neutral with a pH range of 6.0 to 7.0.
When growing indoors, the plant does well in containers filled with peat-based mixtures and a layer of drainage at the bottom. Ensure that the pots are not too small to hinder the plant's growth or too large to add unnecessary moisture.
Watering Needs
Heliotropium parviflorum L. is drought resistant but still requires adequate watering to grow well. Watering should be done when the topsoil feels dry or moisture in the container drops to below 50%.
Avoid over-watering the plant as this can cause root rot, yellow leaves, and wilting. Watering should always be done at the base of the plant to prevent water from sitting on the leaves as it can lead to disease and fungal infections.
Fertilization
Heliotropium parviflorum L. benefits from regular fertilization to boost growth and bloom production. Fertilizers rich in phosphorus are crucial for flowering plants as they help to promote the growth of healthy roots and flowers.
Fertilizers should be applied during the growing season, especially during spring and summer. Always follow the instructions on the package of the chosen fertilizer for the right application rate.
Pruning
Pruning Heliotropium parviflorum L. regularly is essential for maintaining a neat and healthy plant. Pruning helps to remove dead, wilted, and diseased leaves, stems, and flowers.
It is recommended to prune the plant at the beginning of spring, just before new growth starts. Trimming should be done lightly, no more than one-third of the plant's size, to prevent weakening or stunting its growth.
