- Formation of a bush . This is very important especially for Korean shrub chrysanthemums. For this, when the young shoots grow to 10-15 cm and they release 5-7 leaves already, their top should be pinched. When from each leaf left above, shoots will appear, they will also need to be pricked. This contributes to the formation of beautiful lush bushes.

Korean Chrysanthemum: Reproduction
You can propagate Korean chrysanthemums in the same way as ordinary garden ones - seeds, division of bushes and cuttings.
Cuttings are prepared for planting when the temperature of the air warms up to 21-26 ° C. We do it this way:
- in a plant 15-20 cm high we cut off the tip of soft shoots (8-10 cm);
- we remove the lower leaves and stick the cuttings for rooting into a pikirovochny box with moist soil;
- take the box outside and regularly water it sparingly;
- at cooling we bring in the house;
- cuttings take root in two weeks and they can be transplanted to a permanent place.
Planting shoots obtained by dividing the bush and cuttings, should be carried out no later than the second half of May - beginning of June, withstanding between them 30 cm, and for spreading shrubs - 40 cm. The first days after planting, these shoots should be watered abundantly.
Cultivation of chrysanthemum seeds from Korean is more troublesome as follows:
- first you need to collect the seeds from already discolored plants (in autumn);
- early in the spring, sow in boxes with wet ground, not sprinkling with earth;
- put on a sunny place;
- shoots will germinate in a week;
- to strengthen the seedlings and plant them in the open ground.
With this type of reproduction, species specific features of the variety are not preserved, but the flowers are more adapted to different
