Second flowering by pruning perennials

We can stimulate a second flowering of some of our perennial favorites by cutting them back after their flowering period. This also has other advantages. It can also prevent certain varieties from spreading too much by seeding. Karl Ploberger has recorded which varieties react positively to pruning and how exactly this should be done in a video tutorial.  

The following perennials are suitable for summer pruning

  • Delphinium

We #Beetschwestern did this once, whereupon the snails ate the entire plant, which is why we no longer cut back the last surviving delphinium spur

  • Lavender

It produces far fewer flowers than before, but at least we like it so much that we don't usually cut it back ...

  • Lady's mantle

This usually becomes quite unsightly after the first flowering and becomes really beautiful after a summer pruning, even if it hardly flowers at all. But the fresh foliage is much prettier to look at than the brownish leaves before pruning

  • globe thistle

We should try this out, we don't have any experience with it yet

  • Spur flower

These have developed many new flowers after our pruning

  • Steppe sage

As with the delphinium, you have to be careful that the snails eat the new shoots and the whole plant in no time, which is why we no longer cut them back
