Adding organic matter, such as compost or aged manure, to the soil can improve the soil structure and provide additional nutrients for the plant.
Cultivation Methods
The Heliotropium strigosum Willd. var. stellulatum (Maire) Maire plant can be grown both indoors and outdoors. It prefers well-drained soil with a slightly acidic pH level between 6.0 and 7.0. It requires full sunlight for growth, although it can tolerate some partial shade. This plant is adapted to hot, dry climates, so it does not require high humidity or frequent watering. It can be propagated from seeds or cuttings.
Watering Needs
These plants are drought-tolerant and do not require frequent watering. In fact, over-watering is one of the most common causes of death for this plant. Water thoroughly but only when the soil is dry to the touch. Use a watering can or hose to water at the base of the plant to avoid wetting the leaves. During the winter months, reduce watering as the plant enters a dormant period.
Fertilization
Heliotropium strigosum Willd. var. stellulatum (Maire) Maire plants are not heavy feeders and can typically thrive without fertilization.

Pruning
Regular pruning can help keep the plant in shape and prevent it from becoming too leggy or bushy. Prune back any yellowing or damaged leaves, stems, or flowers. Deadhead spent flowers regularly to promote continued blooming. Use sharp, clean pruning shears to make clean cuts.
Propagation of Heliotropium strigosum Willd. var. stellulatum (Maire) Maire
Heliotropium strigosum Willd. var. stellulatum (Maire) Maire is a beautiful plant that can be easily propagated through various methods. The plant can be propagated through seeds, stem cuttings, and division of the root.
Propagation through Seeds
The easiest and most common way to propagate Heliotropium strigosum Willd. var. stellulatum (Maire) Maire is through seeds.
