Lilies are bursting into elegant and colourful blooms in summer.

It’s a dramatic sight, and one you can prolong by simply removing the flowers as they fade. It’ll also divert energy away from seed production, which can reduce flowering performance in subsequent years. If you’re growing martagon lilies, don’t deadhead these as they’ll gradually self-seed.

As you go, be sure to keep an eye out for signs of lily beetles. Look for the bright red adults and their larvae, which cover themselves in their wet, black excrement to deter predators. Pick them off and squash them if spotted.

When tidying up lilies, leave as much main stem and as many leaves as possible as these will help the bulb build up its food reserves for next year.
