Development control
The main task of the gardener is to promptly create the microclimate that is optimal for growing radishes in each time period. The seeds are planted in soil heated to 12°C. After planting, make sure that the air in the greenhouse warms up to 16°C. With the appearance of the first shoots, intensive ventilation is provided: the atmospheric temperature is set at 6o C. On the fifth - seventh day, the greenhouse is covered: the plants are provided with comfortable thermal conditions - 18 - 20o - for the period of molting and further development.
It is necessary to control the density of seedlings. Thickening can lead to a significant reduction in fruit weight, and in some cases, to their absence. But the planted plants are not prone to the formation of arrows.
At first, water the crop no more than once every three days, while making sure that there is no waterlogging - the fruits may crack. Excessive amounts of water can provoke the development of the disease - blackleg. Moisture retention and mulching are effective procedures: humus and peat are laid in a layer of up to 1 cm.
The beds are regularly loosened, giving oxygen access to the root system. If the soil is prepared in advance, the seedlings are not fertilized; in extreme cases, when the development is low, the radishes are fed with nitrogenous substances. Harvesting begins when the fruit size is 2 cm.
Disease treatment
Growing radishes in a greenhouse is associated with certain difficulties, the main of which are diseases. The most common diseases are: blackleg, dry rot, powdery mildew. There are few ways to treat plants: the main one is prevention. Treatment of crops with insecticides is not allowed. In some cases, the fruits are sprayed with a weak solution of copper sulfate. The seed material is subjected to hardening procedures: heated in a water bath at 50°C, then cooled in a 10°C liquid. Often you have to take the extreme measure of replacing the soil: thanks to its timely implementation, it is possible to grow a sufficient harvest of radishes. To prevent the occurrence of fungal diseases, you need to keep the area clean and plant strong varieties.

How to choose the right radish seeds for a greenhouse
When choosing radish seeds for a greenhouse, pay attention to the following points:
- Terms of ripening. Radishes are planted in a greenhouse before planting or after harvesting the main vegetables. In spring it is worth giving preference to early varieties. In autumn, the choice depends on climatic conditions. If there are 1-1.5 months before the onset of cold weather, it is better to give preference to mid-season varieties. They last longer.
- You should not believe promises that root vegetables will ripen within 15-18 days. It is not possible to create ideal conditions in a greenhouse. If you plan to use the greenhouse later for growing other vegetables, choose early-ripening and frost-resistant varieties. They are sown in early April.
- Preference is given to varieties that can be grown throughout the summer. Most likely, even in a greenhouse they will not sprout when the temperature rises.
- Pay attention to the dimensions of the leaf rosette. It is important that the plants do not shade or interfere with each other. Radishes with compact, erect rosettes and small leaves are suitable for greenhouses.
Soil preparation
If something was already growing in the greenhouse in the previous season, mandatory preparation is required. After all, the soil is significantly depleted by the previous “tenants” (tomatoes, cucumbers or herbs). To provide future radishes with proper care, the soil requires replenishment of nutrients.
To prepare you will need:
- remove all remnants of roots and branches from previous plantings;
- dig up the bed, adding 3 kg each. humus per 1 sq. m. area;
- It is also recommended to feed the soil with ash (0.5 cups) or potassium sulfate mixed with urea and superphosphate (1 tablespoon of each preparation).
After the soil is ready, it is leveled with a rake and shallow grooves are made at a distance of 10 cm from each other.
