Autumn Gelenium is a herbaceous plant with branching stems. The height of the stems can reach up to 160 cm.

Inflorescences are presented in the form of baskets, collected in corymbose flowers. The fruit of the plant has an oblong cylindrical achene, with a slight pubescence. Gelenium blooms from July to September. Among all plant species, there are also garden varieties, with yellow-red hues.

Features of autumn helenium

The peculiarity of autumn helenium is the death of the flower along with the stem and rhizome. It is a very light-loving plant that prefers fertile soil. Some varieties of autumn helenium do not need feeding at all.

Therefore, with abundant fertilization of the flower, its uncontrolled growth can occur. To ensure the lush flowering of the plant, it is necessary to cut off the wilted stems in a timely manner. And in order for the flowers to be branched and densely located, it is necessary to pinch off the tops of the shoots.

Planting and leaving

Planting gelenium should begin at the end of autumn. Before planting, the soil must first be fertilized with compost, manure or some other rotten organic matter. In the process of flower growth, it must be periodically divided into stems. If this is not done, then the rosettes of the plant will begin to freeze slightly, and the earth will be depleted. Experienced gardeners recommend planting helenium near fences and other decorative elements. Also, the flower looks good in a bouquet with autumn asters.

Growing this plant should be done in full light. Although the flower is drought tolerant, it needs to be watered regularly. Also, helenium needs to be fertilized with various mineral dressings. Still caring for the plant consists in its periodic loosening, to a depth of seven centimeters. In the event that the helenium has a single planting, then you need to deal with the formation of a bush.

Reproduction

Autumn helenium propagates by seeds and division of stems. It is better to divide the plant in the month of May. For this, slightly grown sockets should be planted. In the process of digging up a bush, the sockets almost independently begin to separate. In the spring, helenium can be propagated by stem cuttings. In order for young shoots to take root quickly and well, they must be placed in a greenhouse.

Reproduction by seeds is a little more difficult, since they have a rather low germination rate. Based on this, it is better to sow seeds at the very end of autumn. Seedlings will bloom next year. Before sowing seeds, they must be stratified. To do this, the seeds should be mixed with wet sawdust and left in this state for three weeks.

Storage of seeds in wet sawdust is carried out at a temperature of about three degrees above zero. After that, the seeds are placed in a special substrate until germination.

The next stage of seed reproduction is diving. It must be produced in such a way that no more than five seedlings are located on one square meter. You also need to remember that helenium does not tolerate numerous transplants, so it is advisable to immediately identify the plant on a permanent site.

If planting seeds is planned in open ground, then this should be done in May, when the ground warms up well. In general, autumn helenium is considered a frost-resistant variety, but prolonged frosts can weaken an already not so strong root system. To prevent damage to the flower, three weeks after sowing, it must be covered with plastic wrap. Sowing can also be carried out initially in a greenhouse. After picking, the plants cease to be vulnerable and are not afraid of low temperatures.

Another way to propagate autumn helenium is by cuttings of green shoots. For reproduction, young annual shoots are used, the average height of which is 10-15 cm. The top of the shoot is cut off and rooting takes place. For the tops to take root well, they can be covered with glass jars or plastic bottles. When the first leaves appear, cans and bottles can be removed.

After the plant is planted in its permanent place, you need to mulch the soil. This should be done with humus, or with peat. To prolong the flowering of the plant, you need to remove the inflorescences with a part of the stem. The division of the plant must be carried out no more than four years, otherwise it will be weak and not frost-resistant.

Pests and diseases

The most dangerous pest that infects helenium is the chrysanthemum nematode. The nematode worm damages leaves and flower buds. All flowers that have been affected by the chrysanthemum nematode must be dug up and destroyed. If this pest was noticed on the site even before planting, then the soil should be treated with ground sulfur or slaked lime.

Also, at the end of July, the plants themselves are processed. This is done with the help of a solution of thiophos. As for diseases, the autumn helenium practically does not lend itself to infections, the only thing that flowers can suffer from is waterlogging. Therefore, you should always monitor the water balance of the soil.
