Add bright spots of colour to dry spots in your garden or landscape with drought-tolerant bedding plants. Bedding plants, perennials and annuals, are used in containers, borders or flower beds. Perennials bloom for a short period of time but live for several years, while annuals germinate, bloom, go to seed and die in a single growing season. Choose a variety of colours for visual impact.

When choosing plants for your garden or landscape, consider factors such as maintenance, moisture and light requirements and fertiliser needs. Low-maintenance flowers don't require constant pruning and deadheading to thrive. Plant species with similar water and light requirements close to one another. Before planting, amend soil with fertilisers, lime or peat moss as needed to ensure a continuous nutrient supply and a pH balance of 6.3 to 6.7. Finally, choose your colour palette.
Planting Bedding Plants
The Penn State Cooperative Extension in Monroe County recommends planting bedding plants on a cloudy day or in the evening to reduce the risk of transplant shock. Place plants at ground level with peat pots completely covered. Add a layer of mulch to hold moisture and reduce weeds.
