I like the article The Petunia is medium in size and 30 cm in height; in the spring, summer, autumn, winter it assumes a pink 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. The Petunia have a one or two year development cycle. Fertilization Petunia
Annual plants have a quite vigorous development and need, during the spring, a continuous fertilization; when placing them let’s add some humus or mature manure or some slow release granular fertilizer to the ground. During the spring months we suggest mixing some fertilizer for flowering plants to the irrigating water every 20-30 days. Exposure Petunia
The Petunia can't stand temperatures below zero; they should be grown in cold green houses or at least in a place where they are sheltered by the wind; when every risk of late freezings has gone by we can place them outside or remove the protections. the Petunia should be grown in a bright place, with direct sunlight.These plants have an annual development, therefore when it becomes cold they deteriorate, and get completely eradicated. Watering Petunia
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. As the cold weather arrives, in autumn, usually waterings is interrupted because these plants can't bear harsh temperatures. Treatments Petunia
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 Petunia
We advise locating these annual plants in a dissolved soil, with an elevated drainage.
