Lupins - When is a pruning sensible?
Basically, the cutting back of lupins is not necessary. Only if you disturb the sprouted plant in autumn, you can grab the scissors. In addition, you should always remove flowered inflorescences immediately.
When do you have to cut back lupins?
There are four maintenance measures where cutting the lupins in the garden or in the pot on the terrace can be useful:
Cut off blooming inflorescences
You should not do without this measure. By cutting off the withered parts, encourage the perennial to form new flowers.
In addition, you prevent seeds from growing in the pods. It spreads throughout the garden, so you can not save yourself from lupins.
Seeds of ornamental lupins are poisonous. That is another reason why he should not even be born in order not to endanger children and pets.
Pruning in autumn
It is often recommended to cut back the lupine shrub in autumn. Of course you can do that, but it is superfluous. The plant will continue to do well without pruning next year.
Most of the plant is absorbed by itself. The remainder serves as a natural protection that protects the soil from leaching in winter.
The remaining over the winter plant stems lay on the ground and rot there in the course of a few months. On the one hand they prevent the emergence of weeds, on the other hand they release nutrients through the decomposition process that improve the soil.
Cut cuttings in spring
To grow lupins, cut new cuttings from the center of the plant in the spring. Put them in potting soil and win new lupines for your garden.
Cut infected leaves
If the plant is affected by mildew, you should cut off the affected leaves generously. Then the spores that cause the mildew, can not continue to spread on the plant.
Tips & Tricks
If you want to remove old lupine plants, cut off only the upper plant parts and leave the root in the soil. It rots there and loosens the soil. It also releases nutrients and serves as a natural fertilizer.
