The end of June is the time to do some summer pruning. If you cut back early perennials now, you’ll be rewarded with a second flush of flowers. Tall and spiky plants like delphiniums and foxglove can be pruned as soon as the tallest spike has faded flowers and this will allow side shoots to take over for weeks of more color.
Bushy bloomers such as coreopsis and daisies can also be sheared back by one half once the flowers fade, and a whole new crop of buds will appear. In the vegetable garden, use scissors to prune and harvest leaf lettuce and you’ll see new leaves popping up to replace the old.
