I like the articleCare Petunia
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. Feed 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. Temperatures Petunia
Let's grow the The Petunia In a cold green house or in the house, as they fear frost; we can move them outside in late spring, with minimum temperatures above zero. Plant which needs at least a few hours a day of sunlight.These plants have an annual development, therefore when it becomes cold they deteriorate, and get completely eradicated. Irrigation Petunia
Watering takes place only when the soil has been dry for days, usually every 1-2 weeks can be enough; if the climate is particularly hot we can slightly intensify the irrigations, using 2-3 glasses of water . As the cold weather arrives, in autumn, usually waterings is interrupted because these plants can't bear harsh temperatures. Adversity 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. Substrate Petunia
We advise locating these annual plants in a dissolved soil, with an elevated drainage.
When wanted we can grow these plants in a vase. The indications given in this article are related to a medium size plant.
