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 36

1. We have the little red and yellow-flowered clover in the lawn. What can you do about it?

The yellow-flowering clover is horn-sourclover (Lotus corniculatus) and has red foliage. What you should do if he gets out of hand in the garden, you can read here. The red clover (Trifolium rubrum) belongs to the same genus as the white clover. He is hardly ever in the lawn, because he does not tolerate the deep cut in the long run so well. Sometimes the flowers of the white clover are also slightly reddish - so we suspect that this clover is causing you problems. Tips on countermeasures can be found in the following article.

2. I have a problem with squirrel from the autumn leaf beetle. The lawn is already brown in many places and can be rolled up in the areas. How can I save him?

The use of nematodes helps against grubs in the lawn. The best time to use is mid-August to mid-September, when the soil is warm enough. So you can do something about it now. The application is recommended in the evening and on cloudy days. Then the soil must be evenly moist (not wet!) So that the nematodes can successfully infect the larvae. Even in spring, an insert may still be useful as soon as the soil warms up, but the pupation has not yet occurred. There is no way to fight the grubs in the soil with conventional pesticides, as the use in the home garden is strictly prohibited.

3. I would be very happy about an effective tip for displacing winds.

Field and fence winches have a deep, far-reaching root system that is difficult to remove. Unfortunately, there is no ultimate method for eliminating the winds. To a certain extent, a fight with Finalsan weed free plus (Neudorff) is possible, the plant must already have enough leaf mass and be about 15 inches high. Make sure that the neighboring plants are not wetted. Otherwise, only weeding by hand. If you do it consistently, the plants are so weakened at some point that they do not regrow.

4. My orange tree suddenly loses all leaves. What am I doing wrong?

From a distance and without detailed information on location and care, we can only speculate about the cause. High loss of leaves is usually a sign of stress. Stress arises in an orange tree, for example, when it has to accept an abrupt change of location factors. Possibly it was also poured too much, in stagnant wetness all citrus species shed their leaves. Often, however, they first turn yellow before falling off later. The yellow color indicates that the fine roots are damaged due to lack of oxygen and the supply of leaves no longer works properly. The care mistakes are usually already some time back, because the orange tree reacts quite slowly to changes in location. You should only water when the top half of the earth is dry. You can say that well with a finger test.

5. Do I really have to dig dahlias or is it enough to cover them?

Because dahlias are not used to the cold temperatures in our latitudes, they must be taken out of the bed before winter so they do not freeze and rot the tubers. Covering them only is not enough, as they sit relatively flat in the ground and are even damaged by light ground frost. You can read more about the right hibernation here.

6. Can I plant a new fruit tree at a place where there was an old pear tree?

An old rule says: One should not plant pome fruit after pome fruit or stone fruit after stone fruit. We advise against it, because as rose plants almost all fruit trees are susceptible to soil fatigue. Better choose a new location or wait four years with the replanting and sow at this time a green manure of marigold or Tagetes.

7thI wanted to ask if you can put hardy bulbs in flower boxes? Or then freeze the onions?

Flower bulbs of tulips, daffodils and haycinths, so spring flowering, you can easily plant in flower boxes. However, you should store them in a sheltered place in winter, for example, close to a house wall, and occasionally water so that the soil does not dry out. Summer flowering bulbs are planted only in April / May with a few exceptions such as the Madonna lily.

8. Is there an alternative to Roundup? I have over 400 square meters of paved area and neither time nor desire to mechanically remove the weeds.

On paved surfaces, the use of herbicides is generally not allowed - regardless of whether it is dealing with chemical products such as Roundup or biological, for example with the active ingredient acetic acid. An alternative are flame-retardants, which kill the weeds by deliberate action of heat. One has to hold the flame on the respective plant only until the green of the leaves shows a slightly changed, blue-green hue. It is not necessary that the plants be completely scorched.

9. My cornelian cherries are certainly already 20 to 25 years old and we cut them down a lot today because they have not worn much in the past few years. What can I do for more income?

Actually, the cornelian cherry does not need to be cut. If it has grown too large, it can be bleached, but only after flowering, because flowers and fruits form on the previous year's wood. With heavy pruning in late summer or autumn, it will hardly bloom next spring. However, the rejuvenation may lead to the formation of new fruit wood, so that your cornelian berry wears better the year after next. However, the weak yield can have other causes, such as poor fertilization due to bad weather during flowering. Late frosts can also be responsible for lack of yields, as the cherries already bloom very early in the year.

10. My rhododendron gets a lot of yellow leaves. What now?

From a distance, we can only guess what your rhododendron might be missing. If some of the leaves turn yellow or reddish in late summer or autumn, then this may also be due to natural causes, because evergreen rhododendrons repel the oldest part of their leaves every two to three years and thus renew their foliage. However, if the yellowing affects a large part of the leaves and also young leaves, nitrogen deficiency, waterlogging or a high pH (lime chlorosis) may be the cause. Nitrogen deficiency is remedied by nitrogen fertilization. In case of iron deficiency (recognizable by yellow leaves with green leaf veins), iron fertilizers combined with a reduction of the pH can help. The latter is a longer process and is achieved by regular mulching with a needle bed.
