The 10 Facebook questions of the week

The Content Of The Article:

Every week our social media team reaches a few hundred questions about our favorite hobby: the garden. Most of them are quite easy to answer for the editorial team of MEIN, but some also require some research effort to be able to provide the right answer. At the beginning of each new week we put together for you our ten Facebook questions of the past week. The themes are mixed - from the lawn over the vegetable patch to the balcony box.

Facebook: The top questions of the calendar week 19

1. Can you actually replenish blue rain?

Although blue leaves can be propagated from seeds, the seedlings often only blossom after eight to ten years. Softwood cuttings from new shoots (about six to eight centimeters long, with buds) are cut from late spring to midsummer and put in a pot with moist soil. The rooting of the cuttings is not always successful. It is better to propagate through the sinker: A long shoot is led down to the bottom and the bark is slightly scratched at one point. This area of ​​the shoot is digged about 15 centimeters into the ground so that new roots form. The end of the shoot must stand out. Cut and transplant the rooted shoot of the mother plant.

2. What can be done against the leek fly or how can the infestation be prevented?

Unfortunately, there is no pesticide against the leekminer fly. Against leek moths helps a special protective net that can be placed over the plant. But the much smaller fly will slip through there, so the net has to be very tight. A good defense is a mixed culture of leeks and carrots, because leek flies avoid the smell of carrots and carrot flies that of leeks.

3. What can be done against the egrets of the cockchafer?

The grubs of the cockchafer are unfortunately not combated. Can help a thorough soil preparation, for example with a motor cutter. Attention: The egrets of the cockchafer are easily confused with those of the rose beetle (Cetonia aurata). Rose beetles are under protection and therefore may only be collected and re-exposed elsewhere. Although they occasionally nibble on pollen and petals, but they do not harm the plants significantly, otherwise they feed on mostly dead plant remains.

The grubs of the rose beetle crawl on their backs, while cockchafer larvae move on their side. Rose beetle larvae are commonly found in compost

4. Can a spinach be propagated over leaf cuttings?

Yes, it works. To do this, separate a leaf from the center of the spinach and cut it across into approximately three centimeters large parts. The best cutting quality results in the centerpieces. They are pressed into propagating soil and placed in a bright, warm place (18 to 20 degrees). Make sure that the soil remains evenly moist - it's best to put a foil hood over it. After about four to six weeks, when the cuttings have roots, they come in single pots.

5. Can you plant bluebells as groundcover between hydrangeas?

Bluebell flowers go well with hydrangeas that grow on rather arid soils in locations that are not shady - for example the panicle hydrangea 'Grandiflora' (Hydrangea paniculata). It should be noted, however, how close the hydrangeas are, for bluebells need a sunny to partially shaded location. You should definitely choose a hardy, low growing campanula like the Dalmatian bellflower. It multiplies over creeping foothills and can be easily kept at bay with the spade at the edges.

The fast-growing Dalmatian bellflower (Campanula portenschlagiana) is suitable as groundcover

6. The flower buds of my freshly planted tayberries are full of wood ants. Can they damage the berries?

The juice of young buds tastes forest ants especially well. Not only on typhoons shortly before flowering, but also often on peonies they are to be found. What that means for your harvest: Yes, it is in danger, because the buds are damaged by the ants. Since forest ants are protected, you should try to evict them - for example, by luring them in another direction with a sugar trail that starts at the ant.

7. Does the angel trumpet like full sun?

Angel trumpets prefer a sunny location. However, you should protect them from the blazing midday sun, as the large leaves evaporate a lot of moisture in the heat and the already high water demand increases enormously.

For the angel trumpet is a sunny, but not too hot place s.besten.During the midday hours, the plants should be protected from the blazing sun, because the large leaves are usually fast flabby

8. I am afraid that I planted my peony too shady last fall. Can I still implement them now or should I wait until autumn?

Peonies generally tolerate poorly when transplanted. That is why it is very important to wait until after flowering. From August to the end of September you can implement the perennial. It is important that the peony is shared equally, because peonies, which are implemented "in one piece", usually do not grow properly and often take years to worry about. This is especially true for larger specimens that have grown for several years in one location.

9. The Dipladenie looks nice, but I have to buy a new one every year. When wintering, all leaves fall off and the plant comes in.

Maybe she was too cold - after all, the Dipladenie is an exotic. Temperatures of 5 to 12 degrees Celsius in winter quarters are sufficient. Then the Dipladenia take a break from October to March. During this time, you should also pour only a little, so that the root ball can dry off in between. Normally, the plants are cut back in late winter (February / March). Do they go out fresh somewhere, or are all leaves really brown? With the nail test - simply scratch something on the shoots with your fingernail - you can find out if there is still life in the plant. If the shoot is also brown, it is dead and you can save the repot.


Dipladenias develop countless funnel-shaped flowers in pink, red or white throughout the summer. They love very bright, sunny places and year-round temperatures above 18 degrees with always slightly humid earth

10. May I pick lilies of the valley in the open air?

In fact, you can not simply pick lilies of the valley in the forest because they are protected. In the own garden the picking of the flower stems is absolutely allowed!
