An ultra-early variety, a compact standard plant, 30-40 cm high. Does not stalk, the fruits are red, round.

  • black soil - 45%;
  • sand - 5%;

How to plant at home: technology from A to Z


  1. It is best to purchase planting material in a store to be sure of its quality and compliance with the declared characteristics.
  2. Before planting, you need to sort out empty seeds that are not capable of germinating. To do this, they need to be immersed in salt water for ten minutes and substandard seeds will float up, while healthy ones will settle to the bottom.
  3. Next, the seeds are soaked for half an hour in a solution of potassium permanganate in order to develop immunity to late blight in future plants.
  4. After all procedures, the seeds are placed in a damp cloth.
  5. After the sprouts of the sprouts have appeared, the seeds are sown into the ground, deepening by a centimeter, observing an interval of three centimeters.
  6. The soil is lightly tamped, cover the container with plastic wrap and put it in a warm place until shoots appear. Small holes must be made in the film for air circulation.
  7. Seedlings will appear in a week. It is necessary to ensure that the soil is always moderately moist.


  1. Tomato seedlings dive in the phase of two true leaves.
  2. To make them easy to separate without damage, watering is stopped two days before the procedure.
  3. Gently prying the sprout with a spatula together with an earthen lump, it is moved into a new container with soil so that the stem is completely in the ground.
  4. The soil is slightly compacted and spilled with warm water.
  5. After a month, during which the seedlings need to be fed with mineral fertilizer, the mature seedlings are transplanted to a permanent place by transshipment.
  6. Dwarf plants can be planted one at a time in separate pots.

Step-by-step instructions for caring for a room crop

Watering and fertilizing

Potted tomatoes respond very gratefully to watering... Moisturizing the soil promotes healthy growth, amicable ovary formation and fruit ripening. Watering is carried out twice a week, without touching the stems. By the beginning of flowering, watering is stopped and resumed only with the appearance of ovaries.

Three weeks after the pick was carried out, special mineral fertilizers are applied for the first time. You need to feed the tomatoes at intervals of two weeks, applying fertilizer on the second day after watering.

Pruning and pinching, pinching

It is imperative to remove shootsformed in the axils of the leaves, that is, pinching. This is necessary for the correct formation of the plant. Not removed in time, stepchildren lead to thickening, take away nutrients and reduce the yield of tomatoes.

Reference! After the main ovaries have formed, you need to pinch the top, and cut off the lower leaves, which have withered during the growth process.

Supports, hanging

Varieties suitable for growing on a windowsill do not have branching, they have a stable trunk, so they do not need a garter. If, nevertheless, such a need arose, then a peg is stuck into the ground carefully so as not to damage the roots, and the branches are attached to it.

Diseases and pests

  • Late blight - a fungal disease transmitted through the air, soil, through seeds and plant debris. Symptoms are dark brown spots on the leaves, eventually spreading to the stems and fruits. Capable of completely destroying crops. For prevention, the method of soaking seeds in potassium permanganate is used even at the germination stage; you can also treat young plants with Bordeaux liquid.
  • Blackleg - a fungal disease caused by thickening of plantings and lack of light. The base of the stem turns black, the plants deform, fall and die. For preventive purposes, the soil is enriched with ash and sand. If the disease is already in the active stage, they are treated with fungicidal preparations.
  • Septoria- infection occurs through the soil. The lower leaves of the plant are covered with grayish spots with black dots, then the leaves turn brown and dry. Prevention - disinfection of the soil with potassium permanganate, the affected parts are destroyed, and the treatment is carried out using the treatment with Bordeaux liquid.
  • Brown spot - light brown spots on the leaves, caused by high humidity and soil flooding. Treatment is similar to septoria.
  • Whitefly - a small insect that sticks to the leaf and resembles scales. Poses a threat as a vector of diseases. Applying enough nutrients will promote resistance, and already emerging insects and their larvae can be washed off the leaves with soapy water or dandelion infusion.
  • Thrips - insects, traces of vital activity of which appear in the form of dry, falling leaves and dried buds. The fight is with sufficient watering and insecticide treatments.
