Fruits with excellent presentation, one might say one to one. They are well transported and do not crack, even if there is high humidity. If storage rules are followed, they do not deteriorate and retain their presentation for a long time.
Tomato inflorescences do not fall off when the air temperature drops to +8 OC. For the ovary to begin to develop, you will have to wait until the thermometer rises to +14-16 OWITH.
Before planting tomato seeds, the soil is treated with a weak and hot solution of potassium permanganate.

Features of cultivation
To get the harvest as early as possible, it is recommended to propagate tomatoes by seedlings. It is recommended to sow seeds in late March or early April. You can use purchased soil or prepare it yourself using the following components:
- peat – 2 parts;
- rotted wood - 2 parts;
- greenhouse soil – 4 parts.
It is allowed to add eggshells or perlite, then the soil will be more loose. The soil mixture is prepared at least 24 hours before sowing. Picking is carried out after the appearance of 2-3 true leaves on the young plant.
The yield of marketable fruits is at the level of 96-100%
Before moving the bushes to a permanent place, they are fertilized twice. It is recommended to add a urea solution to the first, and a mixture of superphosphate and potassium soda, preferably mixed with wood ash, to the second.
Seedlings need to be hardened by taking them out onto the balcony every day for 30 minutes, gradually increasing the period.
At home, it is not recommended to grow seedlings for longer than 60 days. If the plants overgrow, the harvest will be late. To prevent overgrowth, it is recommended to carry out a second pick 21 days after the first.
Planting pattern in a permanent place - 50x45 cm. Per 1 sq. m there should not be more than six plants.
Olga tomatoes should be watered as the soil dries, but at least once every 6-7 days. If the weather is dry, then water more often - once every 2-3 days.
Loosening the soil around plants is mandatory while removing weeds
Do not neglect feeding tomatoes, otherwise the fruits will be smaller in size than stated by the breeder. Fertilizer application rules:
- in a permanent place, fertilizing is applied for the first time two weeks after planting, this can be a yeast solution;
- after another 14 days, add an ash solution;
- after 14 days, fertilize with boric acid and iodine solution.
After each watering, do not forget to mulch the soil. Any organic materials can be used.
Tomatoes of the Olga variety are not afraid of low light, but with a long absence of sun, the total amount of harvest decreases
Pest and disease control
If the Olga tomato is exposed to unfavorable conditions for a long time, then there is a risk of infection with cladosporiosis (brown spot). Recognizing the problem in the early stages is problematic. The disease begins from the bottom of the bush. Chlorotic spots appear, which over time acquire a brownish-brownish tint. Spores are visible on the spots. The pathology gradually spreads to the upper part of the plant. At the first stages, the problem is confused with powdery mildew, so the measures taken do not have the desired effect.
After the appearance of brown spot, not only the soil, but also the entire greenhouse and supports for the garter must be treated with fungicides
High humidity and temperature are favorable for the pathogen. Under such conditions, spores do not die for up to 12 months. To avoid problems, it is important to carry out preventive measures in the greenhouse:
- maintain optimal temperature;
- avoid sudden changes in air temperature;
- ventilate the greenhouse;
- remove all affected parts of the bushes;
- disinfect the soil before sowing and after harvesting.
Important! If cladosporiosis has already manifested itself, then use fungicides based on benzimidazole or dichlofluanid. In open ground, the pathogen appears less frequently.
Conclusion
Tomato Olga is a hybrid variety with very tasty fruits of the same size. The species is high-yielding, undemanding in care, with good immunity and keeping quality.Suitable for fresh consumption, for any preparation and cultivation on an industrial scale.
