Generalities Red valerian
These plants give origin to a brush with a rounded form. The Red valerian is a perennial herb plant. The Red valerian is medium in size and 1 m in height; in the summer it assumes a red colouring. These plants aren't evergreens, which means they lose their leaves some months during the year.
Watering Red valerian
Water rarely, about once every 1-2 weeks with 2-3 glasses of water , keeping the soil dry for a few days before watering again; when wetting we suggest avoiding surpluses, however to wet the soil deep down. Perennial plants are subject to some months of vegetational rest. During these months it isn't necessary to water them.
Treatments Red valerian
Generally during this time of year we suggest a pre-emptive treatment with wide range insecticide and with a systemic fungicide, to prevent the attack from part of the aphids and the development of fungus diseases, often favoured by a mild and damp climate.
Soil Red valerian
We suggest a substratum characterized by an excellent drainage.
