planting

When transplanting into flowerbeds, care should be taken to space each specimen correctly in order to ensure proper root development and consequently aerial growth, achieving proportionate final results; in detail, an average density of 5 plants per square metre is recommended.

Reproduction/Propagation

Vegetative propagation is by apical cuttings.

Irrigation

Use rainwater, alternatively aqueduct water, either manually or with an irrigation system. When transplanting, pay more attention to the seedling, which may be more exposed to water stress in the new site, so avoid desiccation by ensuring constant humidity but not overdoing it. Afterwards, always keep the soil or substrate moist without causing stagnation which can lead to root rot. It is also suggested not to water the flowering plant from above so as not to damage the flowers.
