In what soil does the Rosemary tomato produce the highest yield and what else affects it?
Rosemary f1 tomatoes are an early-ripening hybrid with high yields, unsurpassed taste and aroma, resistant to nightshade viral diseases and late blight.
The fruits contain a high amount of beta-carotene and are suitable for dietary and baby food. In the article we will talk about the advantages and disadvantages of the hybrid, the nuances of cultivation in a greenhouse and in a vegetable garden under a film cover.
History of creation
Hybrid Rosemary (the more correct name is Rosamarin f1) was bred by biologists of the Research Institute for Breeding Vegetable Crops and Agricultural Firm Gavrish in 2003.
Included in the State Register of Breeding Achievements of the Russian Federation in 2004. Approved for cultivation in all regions of the country in open ground under temporary shelter and in film-type greenhouses. The hybrid is specially bred for spring-summer rotation.

Tomato agricultural technology
Growing rules are standard, as for everyone indeterminate hybrids:
- tomatoes are grown through seedlings;
- planting is carried out in well-heated soil;
- bushes are pinched and tied to supports or trellis;
- provide moderate watering with warm water;
- the soil is periodically loosened or covered with mulch;
- fertilize with complex fertilizers.
Seed preparation
Hybrid seeds do not require additional disinfection, since they are processed in production. To increase the percentage of germination, grains are soaked in ready-made growth stimulants - “Epin”, “Immunocytofit”, “Zircon” or use natural remedies:
- Juicy aloe leaves are kept in the refrigerator for 24 hours, then the juice is squeezed through cheesecloth and diluted with water 1:1. The seeds are soaked in the solution for 4-6 hours.In addition to stimulating germination, aloe improves plant immunity.
- A handful of onion peels and 1 tsp. wood ash pour 500 ml of boiling water and leave for three days. Before use, strain and soak the seeds in the infusion for 2-4 hours.
- Dissolve 1 tsp in a glass of warm water. natural honey. Soak the seeds for 5-6 hours.
Important! Before processing in stimulants, the seed is soaked in melt water at room temperature until it swells.
The soil
A mixture of turf, peat and humus in a 1:1:1 ratio is ideal for growing seedlings.
Before use, the substrate is calcined in the oven at a temperature of 100-110 ° C or steamed in a double boiler for an hour.
Sowing
Sowing is done in the last week of March or early April. The seedling boxes are filled with a moist substrate and the seeds are placed in furrows 1.5 cm deep at a distance of 2 cm. Cover the top with a 1 cm layer of soil and cover with glass or film.
The boxes are taken to a dark, warm place. The optimal room temperature is not lower than +24 °C.
Seedling care
The film or glass is removed after the sprouts appear. The boxes are taken out to a sunny place. The seedlings are watered as needed, after the top layer of soil has dried.
To prevent the development of fungus, seedlings are taken out into fresh air for 20-30 minutes.
After 3-4 true leaves appear, the sprouts are planted in separate containers made of peat or plastic, carefully pinch off the root tip.
Landing in the ground
The transfer of mature seedlings begins 60-65 days after emergence, starting in mid-May. The site is chosen on the sunny side, since productivity decreases in the shade. The best predecessors of tomatoes are radishes, dill, parsley, cabbage.
The culture prefers light, nutritious soil with neutral acidity - pH 7. Dense soil is loosened with river sand or peat. The soil is brought to normal using wood ash or chalk:
- sour – 400-500 g per 1 m²;
- medium-sour – 200-300 kg 1 m²;
- slightly acidic – 200 g per 1 m².
Holes for seedlings are dug at a depth of 15-20 cm and filled with a strong solution of potassium permanganate, add 1 tbsp. l. superphosphate. The seedlings are watered abundantly with warm water and transferred together with an earthen lump from a plastic container or planted directly in a peat glass.
There are no more than three bushes per 1 m². Planting pattern – 40x60 cm.
Care
The culture does not require care; it prefers moderate watering and fertilizing with mineral compounds.
Rules of care:
- The humidity level in the greenhouse should not exceed 70%.
- It is undesirable to overwater the soil and at the same time allow it to dry out. The best solution to the watering problem is to install a drip system.
- For glaze use rain or settled water.
- Bushes stepson once every 10 days and form into two stems.
- At the end of the growing season, pinch off the top. The plant will stop growing, and all the energy will go to the tomatoes.
- Execute garter not only stems, but also flower clusters, which can break under the weight of the fruit.
- After watering, the soil is loosened to prevent the formation of a hard crust.
Advice. Cover the soil with mulch (sawdust, straw, hay, synthetic black agrofibre) to eliminate routine weeding and loosening, retain moisture and prevent fungal infection.
Top dressing
Tomatoes are fed at least three times during the growing season according to the following scheme:
- The first organic feeding 14 days after planting is chicken manure with the addition of water in a ratio of 1:10 or ready-made products: “Gumisol”, “Veromistin”.
- The second feeding 14 days after the first - with complex fertilizer “Solution” containing calcium, manganese, potassium and phosphorus. For 1 bush – 2 liters of solution.
- The third subcortex during the period of fruit appearance is “Solution”, 2.5-3 liters for each bush.
Growing difficulties
Tomatoes are sensitive to both deficiency and excess of mineral components. By the appearance of the bushes it is easy to determine the condition of the plant:
- It gains green mass, but does not bloom - there is an excess of nitrogen in the soil. Wood ash will help reduce its amount.
- The bushes stretch upward, the leaves turn pale - nitrogen deficiency.
- Leaves acquire a purple tint when there is a deficiency of phosphorus, and fall off when there is an excess of it.
- The green mass becomes dull when there is an excess of potassium and dries out when there is a deficiency.
The nuances of growing in open and closed ground
The technology for growing a hybrid in a greenhouse and a vegetable garden is the same. In closed ground, they monitor the appearance of the bushes and respond in time to signs of mineral deficiency or surplus. Errors in care lead to infection with fungal spores.
In the south of the country, the crop is grown in unprotected soil, but for the first time after planting it is covered with film, waiting for the seedlings to take root completely. The bushes are also formed into two stems and tied to a trellis or stakes.
Prevention of diseases and pests
Hybrid Rosemary is protected at the genetic level from infection by viral diseases of nightshades (verticellosis, fusarium, tomato mosaic).Seed producers claim that the crop is not afraid of late blight (brown spots, whitish coating on leaves and trunks, ugly shape of fruits).
However, prevention will not be superfluous:
- soil treatment with copper sulfate;
- disinfection of greenhouses with sulfur bombs;
- removing lower yellowed leaves;
- control of moisture level in the greenhouse;
- moderate watering at the root;
- covering the soil with mulch.
The main problem that gardeners face when cultivating tomatoes is leaf curling. If measures are not taken in time, you may be left without a harvest. The reason for this condition lies in an excess of organic fertilizers in the soil, the air temperature in the greenhouse is above +32 ° C, and a deficiency of copper.
Ways to solve the problem:
- application of phosphorus-potassium fertilizers;
- treatment with the preparation “Agrofon” containing copper;
- ventilation of greenhouses to normalize temperature conditions.
The hybrid is often attacked by mole crickets, Colorado potato beetles, whiteflies, aphids, and caterpillars. Modern safe insecticides help fight pests: “Grom”, “Fitoverm”, “Iskra”, “Force”, “Epin”, “Konfidor”, “Commander”.
Harvest Application
The first fruits appear approximately 112 days after germination. Remove the tomatoes carefully, twisting them from the stem, being careful not to damage the thin skin. The shelf life is minimal, so they try to use them immediately.
The fruits are eaten fresh. Due to their delicate skin, tomatoes are completely unsuitable for pickling and whole pickles.
Too soft tomatoes are used for adjika, lecho, sauce, juice, tomato paste.
Reviews
Gardeners' impressions of growing this large-fruited hybrid are mostly positive.
Elena, Kstovo: “Before deciding to grow Rosemary tomatoes, I read the reviews of those who planted them. Inspired, I purchased the seeds. The characteristics and descriptions of the tomatoes on the packaging are true. The seedlings grew strong, I didn’t feed them with anything. I moved it to the greenhouse in early June. Fertilizers included chicken manure and potassium-phosphorus fertilizers. I watered it with warm water once a week under the bush. During drought, the frequency was increased to two waterings. The harvest was a great success; I have never eaten tastier tomatoes.”
Yaroslav, Borisoglebsk: “Last year I tried to grow Rosemary in the garden, before that I planted it in a greenhouse. The bushes are strong, with thick stems, tall. I tied it to wooden stakes and covered it with foil in extreme heat. I didn’t notice any special problems with care. The main thing is to water and feed in moderation. The tomatoes grew large, fleshy and very sweet.”
Conclusion
Hybrid Rosemary or Rosamarin f1 (original name) is an interesting find for lovers of tomatoes with pink thin skin and aromatic, sweet pulp. The plant is reliably protected from the main “tomato” diseases (verticellosis, fusarium, tomato mosaic, late blight), and is suitable for growing in any type of soil. A prerequisite for successful cultivation in the garden is the organization of a temporary film shelter.
Tomatoes love sun, moderate watering, organic and mineral fertilizers. The fruits grow large and fleshy. One thing that upsets us is that they cannot be stored for a long time due to their thin skin.
