The bright blue cornflower used to be considered a nuisance weed and was fought against. Since it has become rare along roadsides and in fields, it has become increasingly popular as an attractive ornamental plant in our gardens. The sowing of the plant is so uncomplicated that there are hardly any pre-grown plants in the garden centers. With our garden tips, you too can look forward to a beautiful sea of cornflower blossoms.
Cornflowers can be sown directly into the bed from mid-April
Sowing indoors
You can start growing the cornflowers on the windowsill as early as March.
- Fill seed trays or seed pots (€16.68) with seed soil.
- Distribute seeds on top and cover thinly with soil (dark germs).
- Wet with a sprayer but do not soak completely.
- Cover the culture vessel with a hood or a clear plastic bag.
- Place in a warm, bright place out of direct sunlight.
- Air daily to prevent mold and rot.
The cornflowers germinate quite quickly and reliably. As soon as the second pair of leaves appears, it is advisable to separate the small seedlings. Each plant gets its own pot. The foil cover is no longer necessary. As before, the substrate is kept moist, but not overly soaked.
By the time of the Ice Saints, the cornflowers have developed into strong plants and can be transplanted to their final place in the perennial bed as soon as there is no longer any threat of night frost.
Direct sowing in the flower bed
From mid-April you can also sow the cornflower directly in the flower bed.
- Chop the soil thoroughly, remove all root and weed clippings and incorporate some compost.
- Level the substrate with a rake.
- Make grooves and sprinkle the seeds in them.
- Cover thinly with soil.
- Water carefully with a very soft stream so that the seed is not washed away.
tips
It doesn't always have to be the expensive seed trays. Old yoghurt pots are also well suited if you drill a small hole in the bottom to drain water. Put some small pebbles on top so that the drain does not clog and then fill in the potting soil.
