With their early to midsummer flowering larkspur are ideal rose companions - especially as they bloom predominantly in shades that do not occur in roses. The imposing flower candles also make an impression in the classic cottage garden and in the magnificent perennial flowerbed. So that they do not seem too massive, one sets the perennials individually, in pairs or in groups of three. Knight spurs are also popular shrubs.

To cut

Dandelion hybrids remount, if one cuts off the stems just after the withering of the flowers a hand's breadth above the ground. That is, they will form new, though less luscious, flower candles until late summer. To support this effort, you should provide the plants immediately after the pruning with some fast-acting mineral fertilizer and pay attention in the future on a uniform soil moisture.

divide

Above all, the Belladonna hybrids are not very durable and must be dug up and shared with decreasing vitality. The Elatum hybrids are a bit more durable, but they often need a makeover on poorer soils after only six years. If possible, do not plant the offshoots back in the same place, otherwise they will be overgrown due to soil fatigue.

Further care tips

High varieties should be supported on wind-exposed sites with a planting rod, as otherwise the flower shoots will bend very easily. When sprouting in spring, make sure you have a good supply of nutrients with compost and horn meal.

proliferation

Chestnut spears are usually propagated by division in late summer after flowering or in spring. Laymen also manage this problemlessly. The young plants for the nurseries are now almost exclusively from Meristemvermehrung.

Diseases and pests

In hot, dry locations with low air movement, larkspur are unfortunately very susceptible to disease. In particular powdery mildew makes the perennials to create. They thrive much more trouble-free in the cool-humid coastal climate and at altitudes of about 500 meters. Even with snails, all types and varieties of the delphinium are very high on the menu. Protect the shrubs especially when they are sprouting from access by the voracious pests.
