Why radishes goes to tops, what to do
The first reason why radishes goes to tops, is a violation of terms of planting. Radish is a vegetable of short photoperiod for normal development of the roots of this plant enough for 11-12 hours of daylight. For example, the light day in the middle zone of Russia is in the month of March, in April, daylight increases to 14 hours in may, it is already 16 hours. If daylight exceeds 15 hours, while the temperature is kept around 20 degrees and above, the radish begins to build up on the tops. To avoid such "whims" of radishes, try to plant it as early as possible, as soon as the ground warms up to around +8+10 degrees.
To go to the tops of the radish can and from-for incorrectly chosen soil. Radish likes loose soil with a high content of nutrients, so before planting be sure to edit it to make humus, manure, peat or any other suitable components. Remember, radishes are well "filled with" only in neutral or slightly acidic soils.
Ignoring the loosening of the soil around the radish, the lack of thinning as well as irregular watering can adversely affect the development of roots. Avoid leaving radish topper watering plants once in two or three days in hot dry weather daily and after each irrigation the soil is loosen, slide the thinning not later than weeks after germination. It is worth noting that the roots of radish can take up to 25-30 centimeters deep into the soil, so water the seedlings need abundant, otherwise the lack of moisture will trigger the release of "shooter".
