Fertilization German iris
Letís use a slow release fertilizer, or manure, when planting, mixing the product to the ground; during the spring letís mix, every 15-20 days, a specific fertilizer for bulbous plants to our irrigation water, starting from the moment in which the first flowers are withering.

Generalities German iris
These plants are bulbeous. This plant in the spring assumes a white colouring; it is medium in size and can reach 1 m high. It doesn't keep its leaves in the winter. When growing these plants tend to go up, developing very little in width, and they tend to have a columnar development.

Letís avoid watering the The German iris excessively, always leaving the soil dry for a few days between one watering and the other, therefore letís irrigate the substratum deeply every 1-2 weeks with 1-2 glasses of water .

Treatments German iris
As the day-time temperatures rise at the beginning of the spring, it is agreeable to practice a preventive treatment, with a wide-range insecticide, which should be applied when there arenít flowerings in the garden. Before the buds become too large, it is advisable to also treat them with a wide-range fungicide, to prevent the development of fungal diseases which spread easily when there is an elevated environmental moisture.

Soil German iris
Letís favour soft soils, with an elevated drainage.
