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.

The top questions of the calendar week 37

1. The trumpet flower is said to take four to six years to flower. Should you cut them back in spring?

Even if flowering does not start until after four to six years, a regular pruning in spring is not wrong until then - so keep the campsis in check and in shape. For the first time you can cultivate the trumpet flower in the tub, in the long term, it is better to plant the lush climber in the garden.

2. What can be done with the seed capsules of the trumpet flower?

If you enjoy planting, you can sow the matured seeds in the capsules. In good locations, trumpet flowers even sow by themselves.

3. My dahlias are beautiful, but they are getting bigger and bigger every year and will soon not fit into my bed. Can they somehow be kept in check?

That sounds like you have to share your dahlias in the spring when you bring them out of the winter quarters. This will automatically make them smaller.

Dug out dahlia tubers

Dahlias bloom from midsummer to late autumn. However, they must be dug out and wintered in the house before the first stronger winter frosts

4. I have grasses in the garden for the first time. When do I have to cut them?

In order to enjoy the inflorescences in winter, upright growing species such as miscanthus and lampreys can only be cut back to about 10 to 20 centimeters in late winter. Pampas grass is an exception: it will be cut later in spring. For upholstery grasses such as blue winged you should pluck only the dead stalks in the spring.

5. I got a red lamprey grass, which should be hardy. But everyone says that it will freeze to death in winter. What can I do to help it survive the winter?

Without knowing the variety, information is difficult, but there are not so many red-leaved lamprey grasses. Probably it is Pennisetum setaceum 'Rubrum', which is only partially hardy and is therefore offered in the trade only as one-year ornamental grass. But you can try the grass frost-free in the house, for example, to overwinter the cool, bright cellar and pour only moderately, because the water requirement in winter is much lower than in summer.

Pennisetum setaceum 'Rubrum'

The African Lamprey Grass 'Rubrum' (Pennisetum setaceum) can hibernate well in mild areas. Otherwise it has the best chances in the house

6. I am looking for a solitary ornamental grass, which comes into its own in a very large clay pot. What can you recommend to me?

Ornamental grasses such as diamondgrass (Clamagrostis brachytricha), blue-grassed oystercatcher (Leymus arenarius), dwarf miscanthus (Miscanthus sinensis' Adagio '), half-high miscanthus (Miscanthus sinensis' Red Chief') and golden-stem grass (Spartina pectinata 'Aureomarginata '), to name just a few. It is important to ensure a good drainage in the vessel, so a drainage layer in the bottom of the pot of expanded clay or gravel, so that excess water can drain.

7. When does Miscantus work best?

Miscanthus should not be cut back until spring, as the dry stalks protect the "heart" of the plant in winter. In addition, this ornamental grass with hoarfrost over sugar is a pretty sight in the bed.

Winter protection Miscanthus miscanthus

For miscanthus (Miscanthus) and other ornamental grasses own leaves is the best winter protection. Therefore, do not cut off the dry stalks in autumn, but loosely bind the long-stemmed grasses with a string in the middle

8. How do I know when my Hokkaido pumpkins are ripe?

When the stalk turns brown and fine corky cracks form around the point of attachment, the pumpkin is ripe. Also, the knock test is useful for determining the degree of ripeness: if the pumpkin sounds hollow, it can be harvested.

9. I have stinging nettles for the first time this year. How do I overwinter it?

With stinging nettles it is best to cut cuttings and not to overwinter the entire plant. In summer or autumn, cut off the shoot tips of the plants with one or two pairs of leaves with a knife and place them in a glass filled with water.Often, the first roots form within a week. The young plants should be pruned a few times to make them bushy. After just two weeks you can pave the new plant in potting soil. If you increase them in the fall, the young plants stay at 12 to 15 degrees Celsius on the windowsill in the house, until it goes out in spring again.

10. Do I have to sow chili every year or can I also hibernate my chili plants?

Chilies can be quite bring over the winter. If the temperatures fall below five to eight degrees Celsius at night, the plants must, however, in the frost-free winter quarters. Chilies are perennial and overwinter at 10 to 15 degrees Celsius in the brightest possible place. Cut back the plants vigorously before winter, pour sparingly and do not fertilize them any more. Check regularly for spider mites and aphids in winter quarters. At the end of February cut off the dry branches and topple the chilies. However, you should keep it as cool as possible, if you can not offer them a very bright place. From May onwards, after the ice saints, they can return to the outdoors.
