Diseases and pests
Being a hybrid, the Dobry f1 tomato has increased resistance to many diseases - fusarium, tobacco mosaic virus. However, like all tomatoes, it is susceptible to other diseases, including late blight. Fitosporin or treatment with copper-containing preparations are used as a preventative measure to combat it.
To reduce the likelihood of infections in the greenhouse, it is recommended to carry out the following treatment every autumn:
- Clear the greenhouse area of plant debris.
- Disinfect the walls, frame of the greenhouse, and all auxiliary equipment with a solution of laundry soap.
- Treat the soil in the greenhouse with biological products - “Fitosporin”, “Shine -1” or chemicals - potassium permarganate, Bordeaux mixture.
- Treat the soil with lime and dolomite flour.
- Sow herbs – mustard, phacelia.
Carrying out these measures in the fall will reduce the number of harmful bacteria that actively reproduce in favorable conditions. Tilling the soil will also help in the fight against pest larvae inhabiting the greenhouse.
Tomatoes are affected by the following pests: slugs, spider mites, and Colorado potato beetles. To combat them when they appear en masse, there are many chemicals, but usually gardeners prefer folk remedies - infusions of dandelion, garlic, hot pepper.

Seed preparation
Tomato Red Rooster: characteristics and description of the variety
Not all seeds of this hybrid have pre-sowing preparation. When purchasing branded seeds, you need to read what is written on the package. Sometimes producers themselves prepare seeds for sowing. These seeds will cost more.
If the seeds have not undergone pre-sowing preparation, you need to do this yourself. To obtain disease-resistant seedlings, seeds placed in a cloth bag are treated for 20 minutes in an aqueous solution (1 gram of crystals per 1 glass of water) of potassium permanganate, and after the procedure the seeds are washed.
Wash Nuno tomato seeds
The next type of treatment is soaking in solutions of biological products that improve germination. You can take note of such drugs as Epin and Zircon. Soaking time is from 4 to 6 hours. Before sowing, you can harden the seeds by placing them in a warm place for a day, and then in a cold place for a couple of days.
Preparing seedlings
Planting of seeds is carried out in prepared containers with a soil mixture, which includes soil, humus and ash. The seeds are buried 1.5 cm into the soil at a distance of 2 centimeters from each other. The containers are covered with film or glass to create a greenhouse effect and accelerate seed germination. The room temperature should not be lower than 24°C. The condition of the top layer of soil should be monitored. You need to moisten the soil using a spray bottle using the drip method.
With the appearance of the third leaf on the plants, the seedlings are dropped one at a time into plastic cups. In order to better develop the root system, the main root is pinched during the dive.
The seedlings will grow in the cups for another month before being planted in the greenhouse. At this time, the plants need to be watered and fed with a solution of nitrophoska (15 grams of substance per bucket of water). A week before transplanting into the greenhouse, it is recommended to spray the bushes with boric acid.

Greenhouse preparation
The greenhouse is disinfected before tomatoes are planted. Wooden structures are fumigated with sulfur, and greenhouses with a metal frame are sprayed with a bleach solution. The soil is changed every five years. The soil in the greenhouse is disinfected with Bordeaux mixture.
Planting seedlings in a greenhouse
Before planting seedlings, you need to add granular complex fertilizers to the soil. They gradually open up in the soil, feeding the roots of the young plant. Planting young plants in the soil of a greenhouse is simple:
- Two weeks before planting, the seedlings are brought into the greenhouse for acclimatization;
- Holes 15 cm deep are made at a distance of 50 cm from each other;
- Complex fertilizers are laid out at the bottom of the hole, which the plant will need in the first stages of its growth. These are nitrogen, potassium and phosphorus;
- The seedlings are deepened to the first leaf slightly at an angle so that lateral roots begin to form;
- The earth is compacted;
- Supports are installed, or twine is pulled from a peg installed near the plant to the crossbar of the greenhouse. The growing plant will be attached to it.
Advantages and disadvantages
A tomato of this variety usually begins to bear fruit somewhat later than most of its counterparts, but its positive qualities should be noted:
- High yield.
- Extended fruiting period.
- Resistance to diseases - fusarium and tobacco mosaic virus.
- Possibility of long-term storage of fruits.
The “Good f1” tomato, judging by the reviews and photos of plants offered by those who planted it in a greenhouse, can bear fruit for a long time, and the shelf life of ripe fruits reaches 30 days.
Unfortunately, late fruiting in the absence of a greenhouse is a disadvantage, since in open ground the tomato does not have time to produce a full harvest.
Some summer residents also consider the disadvantages of the need to spend time on pinching and shaping plants in the greenhouse.
Care
The tall Dobry variety requires special care, which consists of regular pinching. The plant is formed mainly into one stem, that is, all the side branches and stepsons of the tomato are removed, leaving only the main trunk. Excess shoots take most of the nutrients, preventing the development of the central stem and clusters that form the fruits. In addition, the stepsons make the bush too leafy, which interferes with normal air circulation. Thickening of plantings leads to stagnation of moisture, and as a result the development of fungal diseases.
The main problem in caring for plants of such size as the Dobry tomato is that the bushes need to be constantly tied up. When growing tomatoes, you need to use a trellis - two metal stakes are installed at different ends of the bed, on which the thread is first pulled at a height of 30 centimeters from the ground. As the plants grow, a new thread layer is stretched and the bushes are tied to it. The higher the plant grows, the more layers of thread will have to be made.
In a greenhouse it is more difficult to monitor the level of humidity, since, unlike an open area, the greenhouse room is more difficult to ventilate. Because of this, the greenhouse environment is often waterlogged, which makes the plants feel worse and, accordingly, grow more slowly. This is why it is so important to provide greenhouse plantings with fresh air. To do this, the doors of the heifer must be located on both sides so that air can “walk” freely.
Increasingly, gardeners, growing tomatoes in greenhouses, use mulch. Mulching the ground under the bushes allows moisture to stay in the ground longer, so you have to water the plantings much less often.
Tip: sawdust, dried grass and other materials are usually used as mulch, which reliably protect the soil from drying out and waterlogging.
Basic rules for caring for tomatoes grown in a greenhouse
- You need to water the plants once a week, pouring water under the roots and not touching the leaves;
- carry out regular ventilation, while preventing the creation of weeds;
- regularly loosen and weed the soil, both under the bushes and between the beds;
- form plants into one or two stems;
- remove lower leaves that are close to the ground;
- pruning the bushes only in the morning, so that the wounds have time to dry out in the evening;
- carry out at least three feedings throughout the entire season. In the first month, a solution of mullein and fermented grass is added to the ground. Minerals are also added, in particular nitrogen-containing preparations;
- After flowering, fertilizing with nitrogen is reduced, increasing potassium and phosphorus compositions.
Tip: Fertilizers are applied only after watering in the morning.
Greenhouse plants require much more nutrition than those growing in open beds. Therefore, tomatoes regularly need new portions of fertilizing.
Important: for better development of plants in the greenhouse, it is necessary to maintain optimal air temperature (no higher than 25 degrees Celsius), air humidity should be 70%.
Features of cultivation
To get a bountiful harvest of Dobry f1 tomatoes, it is better to grow the seedlings yourself, taking into account the following rules.
Carry out pre-sowing seed treatment:
- For disinfection, use a solution of potassium permarganate, hold for 20 minutes, then rinse.
- To improve germination, soak in growth stimulants such as Epin, Zircon for 6 hours.
The soil for tomato seedlings is prepared light and loose, from a mixture of garden soil, compost and ash. If the soil in the garden is clayey and heavy, add peat. Alternatively, you can use coconut substrate.
Garden soil for seedlings must undergo pre-treatment; for disinfection, it must be calcined in the oven or frozen.

Tomato Dobry
Early ripening varieties of tomatoes are always a delight, but summer does not end in July, after the mass harvest of tomatoes of these ripening periods. I want to get fresh tomatoes from the garden before the end of summer and in the autumn months. To satisfy consumer demand, breeders offer late-ripening hybrid varieties, such as the Dobry tomato variety.
Characteristic characteristics of the variety
The Dobry tomato variety is intended for cultivation in a greenhouse. This is a powerful indeterminate type (unlimited growth) plant, belongs to the group of tall tomatoes. The bush reaches a height of up to 2 meters, which requires mandatory tying to a support and forming the plant into one stem by pinching side shoots. This is the recommendation of breeders. The leaves of the plant are large and dark green in color.
Fruit
Tomato Dobry f1 has dense, rich red fruits, the shape of which is flat-round, and medium in size. Weight ranges from 140 to 170 grams. The pulp is fleshy and sweet. Fresh tomatoes are used in salads; tomatoes produce thick tomato juice due to the density of the fruit. Dobry tomatoes are suitable for canning and have the remarkable property of being easily stored and transported.
Maturation
Dobry belongs to the mid-late varieties. Ripening begins four months after sowing the seeds. That is why it is recommended to cultivate it in a greenhouse, since in the garden it will not have time to ripen before the cold weather. The brushes on the bushes form until October. Productivity is noted as high. From each bush, with good proper care, you can get up to five kilograms of selected sweet tomatoes or up to 10-13 kg from 1 square meter of area.
