Petunia Festive Sky

Petunias flower heavily from spring into autumn, filling a pot, a basket or the front of a bed with colour for months at a stretch. They are fast, cheap seasonal colour and they repay regular feeding with more flowers. Full sun. Good potting mix in containers. Water regularly, at the base rather than over the flowers. Feed fortnightly with liquid fertiliser through the growing season. Trim back if the stems stretch, and replace annually.
