Complete Guide: How to Plant Petunias

Petunias are a superb way of introducing bursts of fun colour into your garden beds, containers and yes, even hanging baskets. The Petunia can do it all. There is a Petunia for every type of summer display and they are available in every colour and colour combination imaginable. These prolific flowering plants can thrive in a range of soil PH levels and will do well in sunny locations as well as partially shaded ones.

Originating from the South Americas, the Petunia is linked to colourful folklore tales. The ancient Mayan and Inca people held the belief that the Petunia’s fragrance had powers and would ward off evil underworld monsters and spirits. According to the folklore, Petunias will thrive where there is positive energy and will not grow in places where there is negativity.

 How to plant Petunias:

  1. Petunias can be planted outside from early May, once all danger of frost has passed. We recommend planting three or four plugs in a 30cm diameter basket or pot for a full display come June. Plant in a hole deep enough to accommodate the plug.
  2. Use freshly prepared soil or a balance potting compost when planting. Place in a sunny or partially shaded location.
  3. To start with, water every three to five days, take care not to get the foliage wet when watering as this can damage the plant and promote disease. It is best to water carefully from the base of the plant, close to the soil.
  4. Ensure drainage is good to avoid waterlogging and rotting the roots, check the wetness of the soil beforehand so that you do not overwater them.
  5. Feed them with a slow release liquid fertiliser every 7 to 10 days throughout the growing season. Deadhead as needed to prolong flowering and encourage new growth.
