Spring and summer bedding will give you colour over a long period and will also fit in your beds. The spotted laurels are happy at the moment as they are small but they will grow big and your fence won't be happy.
Lovely brickwork, but I would be tempted to put a brick path through the lawn too. Looks like the grass is already worn by people walking across it.
My qusetion is if i plant these [spring bedding plants] now how long will they last for and at what point will I be swapping over for summer bedding plants ?
