Cauliflower "Freedom" F1

Did your cauliflower fail to head? Why?..
This question interests many gardeners. The answer can vary: it's both mistakes in cultivation techniques and a lack of molybdenum, which it indeed needs, but in small amounts.
However, few have paid attention to the biological characteristics of this cabbage...
The progenitor of all types of cabbage is wild cabbage, which grows on the Mediterranean and Atlantic coasts of Europe. All species descended from it, including cauliflower, are moisture-loving and not demanding of heat. (The optimal temperature for their growth is +7+20°C). They are also not very demanding of light. At high temperatures (around +30°C), the cauliflower head does not have time to form. It either bolts into a panicle or doesn't form at all. In southern regions, where summer temperatures often hold well above +30°C, the cauliflower harvest is timed for spring or autumn.
Cabbage is a very moisture-loving crop. On a hot summer day, a well-developed head cabbage plant can evaporate up to a bucket of water. All cabbages need regular moisture. In dry weather, a break in watering even for one week prevents cauliflower from forming heads. However, it also cannot tolerate waterlogging.
Cabbage is demanding on soil fertility: you won't get a large head on poor soils. Therefore, to obtain a high yield, the area for cabbage must be well "amended" with semi-rotted manure or complete mineral fertilizer.
In spring, the cause of failure can also be the wrong choice of seeds. When starting sowing, you need to plan when you intend to harvest. Often, too little importance is given to the variety and sowing time: both early and late varieties are sown "with the same brush" - in late March – early April. As a result, both, at the beginning of head formation, fall into a period of high temperatures, and some plants do not produce heads at all, while others may produce underdeveloped panicles. Therefore, in our cool climate, it is preferable to grow early varieties ("Movir-74", "Snezhnyy Shar" [Snowball], etc.)
By sowing seeds for seedlings on March 15-20, we get a full harvest in mid-June. When intense heat sets in, almost the entire harvest is already harvested. However, if the temperature rises above +25°C, the heads begin to crack quickly and will have to be harvested daily.
When growing late varieties, seeds should be sown in mid or late April, aiming to harvest in August-September. It should be borne in mind that in September, when the nights are cold, head development is slower, but it becomes much larger than that of early varieties.
So, what you need to know to get a good cauliflower harvest.
First, select the variety and sowing time so that head formation occurs during a period with not very high temperatures.
Second, ensure regular watering of plants, not allowing the soil to dry out.
Third, when preparing the plot for planting, organic fertilizers or complete mineral fertilizer should be applied.
