Actually, kobei is a very thermophilic vine. Therefore, we practice growing from kobei seeds climbing.
To start growing kobei from seeds, follow their purchase in specialized store... It should be borne in mind that the germination of kobei seeds directly depends on their age. Therefore, it is not worth purchasing last year's seeds, but it is necessary to purchase the seeds of this vine of the last harvest. To plant kobei seeds, in order to get a full-fledged, beautifully flowering plant, you need at the beginning, in the middle of March, as a last resort... Kobei seeds large enough so that they could be seated one at a time, and not in a bunch. Experienced gardeners who have already grown kobei for the beauty of their site recommend soaking the seeds for a while before planting in growth promoter, since such a procedure will help them become stronger, free themselves from seed skin during germination.
To allow kobei seedlings to grow strong before replanting, their seeds should be planted in individual dwellings from the outset. It is very convenient for this to roll up "cups" without a bottom made of foil. Such "cups" must be installed in a larger container, so that the earth does not spill out, that excess moisture would go away, and fill them with more than half of the nutritious soil. Having spread out the seeds of the kobei one by one in each "house", they must be sprinkled with 1-1.5 centimeters of earth. After 10 days, sprouts will appear, which need to be watered regularly. When the kobe becomes larger, it should be transplanted into special larger cups. This is where the prudently made foil cups come in handy, because they are easy to unfold without damaging the roots of the plants, and transplant the sprouts into another container right with a lump of earth. The kobei will have to be transplanted again before disembarking in open ground. This should be done when the plants are still growing and the roots need more space.
Permanent residence in open ground kobei are planted only when stable warm weather is established, because this plant is so thermophilic that it will not tolerate even small frosts. Most likely this will happen in early June.
It is not difficult to grow a kobei from seeds if desired, but she will delight you with her beautiful large flowers.
