Petunias are one of the most popular flowers for summer gardens, loved for their vibrant colours, long-lasting blooms, and versatility. Whether planted in garden beds, pots, or hanging baskets, petunia plants bring instant charm and colour. With the right care, they’ll flower from spring through to the first frosts. Here’s everything you need to know about how to grow petunias successfully.
Choosing the Best Petunia Varieties
There are several types of petunias to suit different garden styles:
-
Grandiflora petunias - Known for their large, showy flowers, perfect for statement displays.
-
Multiflora petunias - Smaller but more weather-resistant, ideal for windy or rainy spots.
-
Trailing petunias - Also called spreading petunias, these are perfect for cascading from pots or petunia hanging baskets.
No matter which type you choose, petunias come in a wide range of colours, from soft pastels to bold purples and reds, making them a versatile choice for any outdoor space.
Petunia Planting Guide
Petunias thrive in sunny spots, so always plant them where they will receive at least six hours of sunlight daily. If you’re wondering about sun or shade for petunias, full sun is best for maximum blooms.
Soil Requirements
Use a free-draining, nutrient-rich potting mix or garden soil. Adding compost improves soil structure and helps retain moisture while keeping the roots healthy.
Planting
Space petunia plants around 20-30cm apart to allow good airflow and growth. In hanging baskets or containers, combine upright varieties with trailing petunias for a fuller look.

-
Watering petunias: They need regular watering, especially in summer. Avoid soaking the foliage to reduce the risk of disease.

Deadheading: Remove spent flowers regularly to encourage continuous flowering.

Pests and diseases: Watch for aphids, whitefly, or powdery mildew. Treat early with the appropriate garden products to keep plants healthy.
