A garden is full of abundance come August. Summer-flowering perennials will be putting on a fantastic display of blooms that can be prolonged through regular deadheading as the season progresses.
Some perennials may not follow the script, straggly growth may droop over paths or lawn edges and the plants may be past looking at their peak. However, all is not lost, as some perennials can be trimmed in August to encourage one last flush of late flowers to enjoy.
