How often should delphinium be fed with fertilizer?

Provide your delphinium with a liquid fertilizer for flowering plants about every two to three weeks. However, this measure is only necessary if your garden soil is not rich in nutrients. If, on the other hand, you have very dark, humus-rich garden soil, fertilizing with compost, humus, etc. at the beginning of the season and another one after the summer pruning should be sufficient.

Should the delphinium flower shoots be supported?

When the flower stems form, you need to support them with bamboo sticks or other sticks. Only dwarf varieties can do without support.

What is the best way to cut delphinium?

It is best to thin out young perennials to two or three flower stems so that the plants do not exhaust themselves from excessive flowering. On the other hand, you can leave five to seven flower stems on older, established plants. Otherwise, after the second flowering in autumn, the delphinium is cut back to just above the ground.

Can I stimulate the delphinium to bloom a second time?

Yes, because plants that have been severely cut back immediately after flowering often develop a second pile in September / October. To do this, cut off the bloomed flower stems to just above the ground.

How does delphinium reproduce?

How delphinium is best propagated depends on the variety. In principle, propagation is possible by sowing in spring (attention, delphinium is a cold germ!) As well as by division in early spring or autumn and by half-lignified cuttings.

Is delphinium particularly susceptible to certain pests or diseases?

Larkspur is susceptible to eating snails (especially the shoot must be protected from snails!), Powdery mildew, spider mites, leaf miners and rust fungi. The delphinium mosaic virus occurs occasionally. As a rule, however, voracious snails and powdery mildew most often cause problems.

Can you also cultivate delphinium in a bucket?

With a sufficient supply of nutrients (ie long-term fertilizers and regular application of liquid fertilizers), delphinium also thrives in the bucket. Bucket culture is particularly useful if the soil in the garden is unsuitable or snails are a major problem.

Can I transplant delphiniums that have been planted out?

Yes, it is also possible to transplant older specimens without any problems. If such a measure is necessary, you can also use the opportunity to split it up.

Is delphinium hardy?

Larkspur planted in the garden is absolutely hardy.

How is delphinium overwintered?

No special protective measures need to be taken to overwinter perennial knight spurs. You should only leave the withered inflorescences standing for one to two year old varieties so that the plants can sow themselves.
