The plant is represented by a herbaceous perennial form. It is formed as a multi-stem bush with a height of 0.8 m to 1.2 m. The root system is fibrous type, well developed. Pubescent shoots. The leaf plates are solid, up to 5 - 7 cm long, simple, slightly serrated, arranged in pairs.

The color of the leaves is deep green. The sugar content of dry leaves exceeds 11%. The flowers are white, collected in a basket inflorescence. The seeds are very small. In the wild, it grows in tropical climates, as an industrial plant is cultivated in warm countries with humid and warm weather. Therefore, in temperate climates, it is grown mainly as an annual crop or as a houseplant.

Choosing a place for planting stevia outdoors

For planting stevia in open ground, you need well-lit and sun-warmed places, protected from drafts. In areas with partial shade, stevia will also grow, but the sugar content in the above-ground parts will be lower. If the average daily temperature drops below + 20, then the growth and development of stevia slows down. The best temperature regime is + 22 + 25 degrees.

In terms of texture, the best soils will be sandy and sandy loam soils with a neutral or slightly acidic environment. Heavy clay soils can be improved by the introduction of sod land, sand, humus.

Stevia does not tolerate drying out of the soil and needs additional watering 2 - 3 times a week and the introduction of complex fertilizers every 15 days. For growing stevia in the open field, the best way is to grow by sowing seeds for seedlings, or you can plant stevia in the ground with green cuttings after the roots appear on them.

Growing stevia outdoors

Due to the fact that stevia does not winter in most regions of the country, it can be grown as an annual crop through sowing for seedlings. You can find seeds for sowing seedlings in specialized stores. Now they offer several varieties of stevia with an increased sugar content, up to 20%:

  • Delight
  • Detskoselskaya
  • Ramon sweet tooth

In the first decade of March, a soil mixture is prepared for sowing seedlings. There are no special recommendations on its composition, but it is important not to add peat, and add sand. Sand can be taken up to 1/3 of the total volume. The earth is moistened and the seeds are laid out on top, without embedding in the ground.

Cover with glass and put in a warm, bright place. After a week, seedlings appear, which grow very slowly in the first weeks. The glass is removed. The growing temperature should be at least + 25. At the age of 21 - 25 days, the seedlings are dived into individual pots. In early July, they are planted in a permanent place.

You need to be prepared that stevia seeds rarely give 100% shoots, and only half of the shoots received survives. An important condition for caring for seedlings is watering, spraying with warm water and maintaining the temperature.

Planting stevia with green cuttings

To get stevia cuttings in the spring, you need to dig up several plants in the fall, plant in pots and bring them indoors. Cuttings are cut from the shoots of the mother plant in mid-May. Each should have 3 - 4 internodes. Sweet water is poured into a suitable ceramic or glass dish, 1 tsp is added to 1 liter of water. Sahara. Put cardboard on top with holes in the thickness of the cuttings.

Leaves are removed from the lower internodes and cuttings are inserted into the holes so that they sink into the water. The water is changed every three days, and the top of the cuttings with leaves is sprayed with sugar and water twice a day.

Its concentration is 10 g per 1.0 l. From above, the cuttings are covered with a large-diameter cut-off plastic bottle. Roots appear on the 7th - 8th day. As soon as they reach a size of 2 - 3 cm, the cuttings are planted in open ground. Before planting, it is advisable to take out the pots to the open air to harden the stevia.

Stevia care during the season

Despite the fact that stevia loves good lighting, in the first week after planting in the ground, it is advisable to stretch a material that is semi-permeable to sunlight over it, for example, gauze. In 14 days after transplanting seedlings or cuttings, feeding begins. The first can be carried out with complex mineral mixtures diluted according to the instructions.

The next feeding is carried out after another two weeks. A mullein diluted in water will do in proportions of 1 to 10. The frequency of the next dressings is once every 14 days. Also, during the entire planting season, stevia is weeded, removing weeds while simultaneously loosening the soil under the plants. In hot summer, stevia planting needs systematic additional watering at least once every 3 - 5 days.

If stevia care is organized without big errors, then by the fall you can get powerful bushes more than a meter high. For personal use, the green parts of the plant are dried and applied as needed.
