Many gardeners realize the benefits of pruning woody plants and trees. But perennials can really benefit from some pruning too! Montauk Daisies, Nipponanthemum nipponicum, have a tendency to get huge and splay open late in the season, just as they come into flower. It’s nearly impossible to stake them or tie them and still make them look natural.
The solution to this problem is a little shearing early in the season. In May, cut back the growth by at least a third. Have no fear! They will rebound quickly, and the result will be a dense plant with shorter stems, capable of holding the flowers upright in Autumn. If you want a much smaller plant than previous seasons, consider one more pinching in June, before flower buds are set.
