Not every greenhouse radish can grow well and quickly. For this he needs to provide certain conditions.
- There can be any type of greenhouse, but if it is a question of growing radish in a greenhouse in winter, then only good non-film greenhouses that can retain heat are suitable.
- Growing radish in a greenhouse involves maintaining a certain microclimate. The temperature required for germination is +18 degrees. At lower temperatures, development will be slow. Growing a root crop requires a temperature not lower than +10 degrees, and for pouring it + 15 ... +18 degrees.
Important! If you need a lot of radish and there is no time for regular germination of seeds, you can make thickened sowing in a separate container at home (like seedlings), and then plant the radish as needed in the greenhouse, to a permanent place. This will not only simplify the work, but also provide the gardener with shorter terms for ripening the crop.
- Heating can be any, as long as the temperature is correct. It may be central heating, heater, charcoal stove, biofuel and so on.
- Illumination is regulated regardless of the period of the year. For winter greenhouses need to do artificial lighting. Light day should be 8-12 hours. Illumination remains within 900-1200 lux.
- Humidity is maintained at 70% throughout the year.
- Airing is mandatory, even if it is cold outside. In greenhouses, with a constant stagnation of air, fungal diseases often develop, so you need to adjust the ventilation system or ventilate the building simply by opening the window.
Soil and Seed Preparation
Soil for planting radishes
Radishes can be of different varieties, but their planting is not much different. Culture roots go down to the ground by 25 cm or less. As in the case of the cultivation of any other root, there need a loose and fertile soil. If there is bad land in the greenhouse, it is brought back in the fall (1-3 months before planting), fertilized and well dug up.
Make a fertile soil of several components. 500 kg of humus, up to 4.5 kg of superphosphate, 3 kg of “Kalimagnesia”, 1.8 kg of sulfate sulfate, 2.5 kg of ammonium nitrate are taken per one hundred part. All these components are well mixed, and then distributed over the greenhouse under the digging.
Important! Use for fertilizing radish or soil for it, fresh manure is impossible. It spoils the taste of the root, makes it bitter, tough.
Seeds should be designed specifically for growing radish in a greenhouse, as not every variety will grow well indoors at high humidity and poor light. Before planting, they need to be treated with a weak solution of potassium permanganate (insist in the solution for 5-15 minutes), and then germinate in a paper napkin so that they have small roots.

Radish 12 days
Radish seeds can be sown simply in the greenhouse soil or in separate boxes, which are then installed on the tier racks or table tops. But regardless of where exactly the crops will be located in the greenhouse, it is necessary to sow radishes correctly. In the ground are made furrows 1.5-2 cm deep. The ground should be soft, loose. Germinated seeds are not densely sown in the furrows and covered with earth. Tamping them is not necessary, but it does not hurt - you will see the place of sowing.
Interesting! Watering is always warm, not hot and not cold water. Can be defended, but the main thing is that it is fresh.
After the greenhouse has been established for the cultivation of radish and the crop itself has been sown, it must be provided with proper care. Radish grows quickly, but to get a lot of root crops throughout the year, you need to put a lot of effort.
- After sowing, the bed is left for a while, so that the seeds germinate. The only thing that may be needed is watering. It is impossible for the earth to dry up, otherwise the root crop will simply not develop. Watering radish 2 times a week with the calculation of 15 liters of water per square meter.
- Watering conducted root or in the form of sprinkling. The latter is very useful at high temperatures and you should not be afraid to use it, because there is no scorching sun in the greenhouses, so there will be no burns on the leaves.
- If sprouted shoots grow too thick, you need to thin them. Growing radish in a greenhouse involves plant normalization, otherwise you can not wait for a good harvest. Between individual seedlings, 2-3 cm of free space should be left so that the root crops have room to grow.
- Top dressing bring with watering or separately. But often they can not hold. Radish ripens quickly, and if it is too late to feed it, the fertilizer will not have time to completely decompose and can harm the taste of the root or reduce its benefits. Feed radishes better 1-2 times during the entire development. Once after germination, the second - after 1 week, if growth will slow down.
- To reduce the amount of watering and provide radishes with a good nutrient medium, the aisle can be mulched with peat, humus or compost.
- The vegetative period of radish depends on the variety and varies within 45 days. Harvested as ripening. Perederzhivat it in the ground is not recommended, especially if it is for sale, because many varieties are susceptible to cracking.
Nuances of greenhouse cultivation
The main problem faced by gardeners when growing radish in a greenhouse - diseases and pests. High humidity, a variety of crops, the absence of low temperatures lead to the reproduction of fungus, mold, as well as a number of heat-loving insects.
Most of all from insects radishes like to eat cruciferous flea. If they were seen in the greenhouse (even if not on the radish itself, but on another plant), the planting of the radish should be treated with tobacco dust or well chopped wood ash. They need to sprinkle the tops and the ground around.
Growing radish in a greenhouse can be a real problem if rodents are common on the plot. From field mice, which often "wander" into the greenhouse, will help electric repeller, a cat, a bait or a trap.
Important! To avoid certain diseases on the radish or pests, it is necessary to choose varieties of radish resistant to them and plant only them.
Diseases in greenhouses are not uncommon. And if you do not fight them from time to time, they will completely fill the entire room (walls, earth, plants, ceiling, and so on). For radish, powdery mildew and bacteriosis are the most destructive. It is possible to cope with them by spraying the beds with biofungicides "Planriz", "Fitosporin-M", "Alirin-B".
