Irrigation of Regal Pelargonium

Pelargonium grandiflorum (Andrews) Willd.

The irrigation regime for Regal Pelargonium is based on the 'dry cycle' principle, requiring the substrate to dry out between waterings, as the crop is extremely sensitive to waterlogging and standing water.

In the reference 5 varieties crop Regal pelargonium, where this is mentioned in the description.

For Regal Pelargonium, it is critical to ensure the top 2.5 cm of the substrate dries out before each subsequent watering. Excess moisture combined with low light levels triggers root system decay and the development of gray mold, necessitating strict drainage control and the removal of water from the saucer.

The application technique involves watering exclusively at the base; moisture on the leaves and inflorescences is unacceptable due to the risk of fungal diseases. Irrigation frequency during the growing season is approximately twice a week, with a significant reduction during the dormancy period; failure to manage the water regime directly inhibits the flowering processes in this species.
