In the greenhouse / indoors

• July is the ideal time to sow spring-flowering perennial seeds for next year in trays filled with good quality compost. Try aquilegia x hybrida ‘McKana Giants Mixed’, bellis and delphinium hybridum ‘Magic Fountains Mixed’.
• Sow summer-flowering perennials such as scabious ‘House’s Novelty Mixed’, echinacea ‘Green Twister’ and hardy geranium ‘Reflections’.
• Prepare for winter containers by sowing viola hybrida ‘Rose Shades’ in the greenhouse.
• For flowers that bridge the gap between spring and summer, grow biennials such as forget-me-not, foxglove ‘Alba’, sweet William and beautifully scented wallflowers for flowering next year.

Direct sow outdoors

• Sprinkle forget-me-not (Myosotis syvatica) seeds outdoors from May to September to mimic the natural process that follows their spring flowering. Ideal for areas of dappled shade.

Plant outdoors

• Fill any gaps in your beds & borders with garden-ready scented annuals for fragrant displays over the course of the summer.
• Plant up a beds of foliage bedding to fill any gaps with texture and colour.
