A flowerbed full of vibrant bedding plants is one of the easiest ways to add instant colour, height and scent to your garden. Popular since Victorian times, bedding plants are ideal for relative beginners because they offer the chance for results without too much difficulty. Not only that, but you’ll see the impact almost immediately. Summer bedding plants should be planted out in late May or early June once the last frosts have passed.  You can plant winter bedding plants in autumn, to allow roots to take before the soil becomes too cold.
