GETTING THE BEST FROM PETUNIAS...
Petunias will flower in partial shade, but the more sun they see, the more they’ll flower.
Well-drained soil or potting mix is essential.
Although petunias are drought tolerant, they give their best with summer watering.
Maintain peak flowering performance with controlled-release fertiliser or regular liquid feeding.
Most modern petunias don’t require much deadheading, but occasional light trimming helps keep plants tidy and encourages further flowering.
