How to grow seedlings

Sowing seeds begins 60 days before planting seedlings in closed ground, transplanting into open beds is carried out a little later.

Seeds do not need disinfection before sowing. They undergo all the necessary processing before selling. Only the soil is prepared independently. The potting mix is ​​made from garden soil and humus. You can add some washed river sand to lighten the soil. The grains are laid to a depth of 1.5 cm, covered with peat, moistened with a spray bottle and the planting containers are placed in a warm and dark place.

Sowing can be done in a common wooden box or in separate plastic glasses and peat pots.

After the appearance of the first shoots, the containers are rearranged in a well-lit place. Moisten the soil as the top layer dries up with warm, settled water. For watering use shallow watering cans or a regular tablespoon.

When two real leaves appear, the seedlings are dived, seated in an individual container. During this period, spend first feeding liquid complex fertilizer.

2 weeks before planting the seedlings, hardening begins, taking the seedlings out into the open air for 2-3 hours. The time spent outdoors is gradually increasing to 16 hours. The temperature in the room at night, where the seedlings are located, drops to 12-13 ° С.

How to grow tomatoes

After 2 months, the seedlings can be moved to the greenhouse. Tomato should be planted on open beds a little later, when the soil is completely warmed up. For 1 sq. m, no more than 3 bushes are placed in order to exclude the thickening of the planting. Planted in a checkerboard pattern so that the plants do not suffer from a lack of sunlight. With this arrangement, the bushes are well ventilated, which prevents the development of fungal diseases.

The soil for planting is prepared in the fall. The earth is dug up and treated with copper sulfate (1 tablespoon per 10 liters of warm water). In the spring, one more top dressing is introduced in the form of peat, humus and sawdust. Add 3 tbsp to this mixture. l. superphosphate and 500 g of wood ash. Then the soil is dug up again and treated with a solution of lime. All this is done 10 days before transplanting seedlings into the ground.

After transplanting the seedlings into shallow holes, the soil is moderately watered, loosened, spud and mulched with straw. It is useful to spray young bushes with Fitosporin solution for the prevention of fungal and viral diseases.

Regular watering is established as the seedlings take root in a new place. Always watered strictly at the root, preventing moisture from entering the leaves, no more than 2 times a week. The culture responds well to drip irrigation. For this, a plastic bottle without a bottom is installed in the root system and water is poured into it, which gradually penetrates to the roots.

The culture begins to spawn immediately after transplantation. The plant is formed into 1 or 2 stems, removing all stepchildren above the third brush.

Top dressing is carried out 3 times per season with a full range of fertilizers:

• the first top dressing is applied during flowering;
• the second - during fruit setting;
• the third time is fed during the fruiting period.

A tall culture needs a mandatory garter. Next to each bush, a solid support is installed in the form of wooden stakes or metal rods. In the future, branches are also attached to this support, otherwise they will not withstand the weight of the fruit.

The garter is especially important during mass ripening, when ripe vegetables noticeably weigh down the fruitful clusters, as can be seen in the photo.

Diseases and pests

The culture has established itself as a variety resistant to the main diseases of the Solanaceae family. For the purpose of prevention, they are treated with copper sulfate, which reduces the risk of developing fungal diseases. Moderate watering, loosening of the earth and regular weeding of weeds also serve as prevention. Compliance with the rules of crop rotation and agricultural technology enhances the plant's immunity.

Young tomatoes suffer from aphids, whiteflies, thrips and slugs. In the fight against these parasitic insects, spraying with celandine broth or industrial insecticides helps. But do not forget that the use of chemistry is possible only before the appearance of the first ovaries.

Treating the stem with warm soapy water will save you from aphids. And ammonia will help get rid of slugs.

One of the most effective preventive methods is to regularly check plants for pests. Systematic monitoring of the condition of tomatoes will save them from the invasion of pests, and a small number of parasitic insects can be easily dealt with using folk methods, without the use of chemicals.

The nuances of growing in open ground and in a greenhouse

The Dutch hybrid is recommended for cultivation in all regions of our country, including the Urals and Siberia. In cold regions with a short summer, the tomato is advised to grow in greenhouses, otherwise the constant exposure to cold can affect the quantitative indicator, reducing it by 30%.

On a note. The growth of greenhouse and outdoor plants is practically the same, but the fruiting rate is usually slightly higher in greenhouse plants.

In greenhouses, it is especially important to monitor the air temperature and humidity of the beds. Infections and mold are most likely to develop here.Regular ventilation of closed structures reduces the risk of diseases and destroys the habitual habitat of some insect pests.

Harvesting and application of the crop

Harvesting ripe vegetables begins in the second half of July, closer to August, and lasts until the first frost.
