Secrets of how to grow large onions
The turnip is planted by all gardeners, but not everyone will be pleased with its size. Agree that peeling and chopping large onion heads is much more convenient and faster than spending half a day with small things, especially during the conservation period. Therefore, the "caliber" of the crop for this crop plays a primary role. There are some nuances of how to grow large onions that affect the size of the bulb. Late planting, the wrong variety and care errors are what can negate all efforts. However, if you do everything right, then the harvest will not only be plentiful, but also of high quality.
So, what needs to be done so that the onion grows not only lush feathers, but also large bulbs? For a good harvest, the following factors matter:
- selection of the appropriate variety;
- landing dates;
- competent care (especially in terms of watering and feeding).
Let's consider each item in more detail.
How to choose a variety?
If you keep the set warm, then after planting it will go into the arrow and there will be no large onions. The optimal storage conditions for the bulbs are the temperature not higher than 2 ° C heat.
In addition, when choosing a variety of onions, you need to focus not only on varietal characteristics with regards to size. More important is the information on zoning. Onions need a long day of light, so for the southern and northern latitudes you need to use "your" variety.
When to plant onions?
Timely landing is equally important. In general, onions are not afraid of frost, but not varieties grown for the sake of root crops. They need warmth to grow, especially in the soil. If you plant a seed in an unheated ground, it will shoot arrows and will not grow a large onion. Moreover, in the case of late planting, in dry soil, plants will develop slowly, which will affect the yield.
You can start planting onions when the earth warms up to 10 °, and the air temperature will be 5 ° C. Depending on the region of cultivation, this is the end of March - beginning of May.
How to grow large onions: the subtleties of care
Large onions will be in the event that the onions have enough nutrition. The poor land must be fertilized even before planting, digging in the fall with the introduction of organic matter (humus) and nitroammophoska.
During the growing season, planting onions for growing heads will need at least 2 additional fertilizing:
- The beginning of June - urea solution (1 tbsp. L. Per 10 l of water).
- End of June - a solution based on nitroammofoska (2 tablespoons per bucket of water).
If the bulbs are slowly gaining weight, you can carry out another top dressing by watering the beds with a superphosphate solution (40 g per bucket of water). It is also important not to forget to regularly moisten the soil, but not with cold water.
