Larkspur is absolutely hardy and does not need winter protection outdoors
Larkspur is absolutely hardy
The often found in German gardens perennial larkspur (lat. Delphinium) is popular not only because of their delightful, usually in different blue or violet blooming flowers, but also because of their winter hardiness. In contrast to many other garden plants that are not native to Germany, you can leave the larkspur planted in the bed unattended in the open air.
Dandelion prepare for the winter
However, the winter-hard larkspur needs a certain preparation for the winter, so that he drives out all the better in the following spring. It is essential to cut back the plant after the autumn bloom to just above the ground. On the other hand, leaving the decayed plant parts on the plant over the winter, it can germinate disease germs - it is known that Delphinium is particularly sensitive to mildew, gray mold and various bacteria.
Autumn composting
After the cut, you can - if desired - make a division of the perennial. Then it is recommended to mulch the root area with mature compost soil. This supplies the larkspur with nutrients over the winter and already creates a good basis for the budding in the spring. Compared to mineral or artificial fertilizers, compost is not readily available, but gradually releases its ingredients. Thoroughly work the compost into the ground.
Protect delphinium in the pot from frost
In contrast to the really absolutely winter-hardy Delphinium perennials in the garden, larkspur in the pot should be protected at all costs. After all, there is a risk that the substrate - and thus the roots - will freeze and enter the plant.
Larkspur in the tub should be poured in winter on frost-free days, but never fertilized. With the fertilization you can start again from the beginning of March and stop the gifts from about mid-August / early September.
Tips & Tricks
Although planted garden knight spur can be very easily supplied with organic fertilizer, but Delphinium in the bucket needs much more nutrients and should therefore be fertilized with liquid fertilizer.
