Full cultural instructions will be provided with your flower seed, but the key points to bear in mind are: Select the correct mixture for the soil type and drainage characteristics of your site. Prepare a firm, weed-free tilth. Low nutrient regimes are best, which can involve removing the topsoil and sowing onto subsoil. Sowing time throughout the year, with best results sowing March/April and August to September. Sowing rate 5g/m2 - bulk up the mixtures with silica sand when sowing to make it easier to broadcast the seeds evenly. Then rake the seed lightly into the surface.
