Petunias are a lovely flowering plant that offer (almost) instant colour to your garden. The plants are available in a range of colours and styles and can be planted in pots, hanging baskets and directly into the garden.
You can grow petunias from seed, but seedlings can be bought relatively cheaply from plant nurseries.
Plant petunias in mid-Spring, in well-drained soil, preferably in full sun. They can grow in partial shade, but the more sunlight you give them, the more flowers you will get.
Petunias prefer to be out of the wind, and like a little fertiliser about once a month. Water at least once a week, more often when temperatures are consistently hot.
