Border and Patio Petunia

Petunias make excellent patio, bedding and border plants, producing wonderfully bright flowers with varieties that also have markings in contrasting colours. They flower prolifically during the summer months with colourful blooms against a background of distinctive foliage.

Creating a fabulous Hanging Basket display

Petunia are the perfect hanging basket plant, and will create an avalanche of fabulous colour. They also work well in baskets or containers where the blooms can spill and trail over.

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.
