Zinnias will flourish if planted out or sown directly when the soil temperature reaches 10oc(50oF). Then after ensure plants have plenty of space and they’ll reward you handsomely.

Deserving a place in every garden, these ornate and flamboyant blooms provide some of the boldest and brightest garden displays. The resilient flowers hold their shape whatever the weather and flower continuously over a long season. Butterflies are also highly attracted to their vivid colours. If you have not tried these beauties before, we urge you to give them a go. There are free-flowering, compact varieties for border edges and patio containers and taller varieties for stunning mid-border drifts and long-lasting cut-flower displays.

How to Sow and Grow Zinnias
Plants prefer fertile, free draining soil and an open, sunny position. Sow outdoors where they are to flower. 0.5cm(1/4in) deep, directly into finely prepared soil which has already been watered. Thin seedlings to 30cm(1ft) apart. Water well until plants are established. Or, sow indoors in trays of compost. Place in a greenhouse, cold frame or keep indoors at approx. 15°C(60°F). Transplant seedlings 5cm(2in) apart to other trays when large enough to handle. Gradually accustom young plants to outside conditions, before carefully planting out 30cm(1ft) apart, when frosts are over.
