We suggest adding to the irrigation water, in the spring, every 20-25 days, a specific fertilizer for flowering plants. We can also mix to the soil near the plants a granular slow release fertilizer, which has a 3-4 month action.
Generalities Polemonium caeruleum
The Polemonium caeruleum is a perennial herb plant. The Polemonium caeruleum is small in size and 45 cm in height; in the summer it assumes a purple colouring. These plants aren't evergreens, which means they lose their leaves some months during the year. These plants give origin to a brush with a rounded form.
Watering Polemonium caeruleum
Perennial plants are subject to some months of vegetational rest. During these months it isn't necessary to water them. 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.

Treatments Polemonium caeruleum
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 Polemonium caeruleum
We suggest a substratum characterized by an excellent drainage.
