I have just moved and only grass in garden. Am a complete gardening beginner. Is there anything I can plant this time of year to add some colour to the garden. Shrubs or flower, preferably something that will come back yearly.
Mark out the position of new borders and beds. Prepare the ground by killing the existing grass, either by covering to exclude light or by using Roundup or similar.
Plant trees, shrubs and perennial flowers when the ground is free of weeds and grass. Autrumn is a good time to plant. Plant sprig bulbs in autumn too.
