We enjoy planting 'Sweet Summer Purple Bicolour' in both cottage and wildlife gardens, where its blooms attract bees and butterflies, helping to support local biodiversity. With its compact size, extended flowering season, and bold colouration, it's a dependable and cheerful addition to any garden setting.

To create optimal planting conditions for Phlox in your garden, we advise selecting a site with well-draining soil and ample sunlight, ideally receiving at least six hours of direct sunlight daily. Ensure the soil is fertile and rich in organic matter by incorporating compost or aged manure before planting. Space Phlox plants about 12 to 18 inches apart to allow for adequate air circulation and prevent overcrowding. Mulch around the base of the plants to retain soil moisture and suppress weed growth.

We recommend watering Phlox regularly, ensuring the soil remains consistently moist but not waterlogged. During periods of drought, provide supplemental watering to prevent the soil from drying out completely. Apply water directly to the base of the plants, avoiding wetting the foliage to reduce the risk of fungal diseases. Feed Phlox with a balanced fertiliser once a month during the growing season, following the instructions on the fertiliser label. Alternatively, incorporate a slow-release fertiliser into the soil at planting time to provide nutrients gradually throughout the growing season.

Phlox generally requires minimal care once established. Deadhead spent flowers regularly to encourage continuous blooming and prevent self-seeding. Prune back the stems after flowering to promote bushier growth and a tidy appearance. Monitor for common pests like spider mites, aphids, and powdery mildew. Treat any pest infestations promptly with appropriate insecticides or fungicides. Phlox is relatively resistant to diseases and pests but may benefit from occasional inspections to catch any issues early and maintain the plant's health and vigour.
