Why doesn’t potatoes bloom and how dangerous is it for the plant?
Many questions related to vegetable growing arise from a lack of understanding of their essence. Among them is the problem of potato reproduction, which is very relevant in our country. Knowing that this root crop can multiply in two ways, namely, with the help of seeds and vegetation, gardeners are often faced with the topic of potato flowering. So why doesn’t potatoes bloom, and can this affect tuberization??
The ability for vegetative and seed reproduction is inherent in this plant by nature. A person studies the comparison of these two methods of reproduction in school biology lessons. Gardeners are well aware of this aspect of nightshade. Only summer residents who plant potatoes of different varieties and ripening periods in their plots always neglect this knowledge..
The absence of a potato flower: problem or pattern
Potato bloom depends on many factors, and only a few of them directly affect the tuberization process. Let’s consider the reasons for the lack of flowering in a potato field in more detail:
- Will the bush bloom or not? In order to form full-fledged tubers, potatoes do not have to bloom at all. In some manuals on potato growing, you can find recommendations on the deliberate removal of flower stalks and buds. Agronomists, after conducting several studies on this topic, came to the conclusion that the breakage of ovaries and flowers has negative consequences, but not at all due to the absence of the flowers themselves. During bud set, many varieties begin to form tubers. Now you need to make a strong top dressing and increase watering. There are potato varieties in which the flowering and tuber formation cycles do not coincide. In our latitudes, it is customary to plant potatoes with medium early ripeness, namely, its tubers are formed during the flowering process.
An important point – when cutting off peduncles, summer residents trample the aisles and break off the greens of the tops, which leads to a decrease in yield!
- Is the variety important for the formation of peduncles? There is an ultra-early potato variety. Their roots are formed so quickly that they pass all known diseases, ripen until the summer of the Colorado beetles, but at the same time they absolutely do not have time to bloom. For example, the varieties “Roco”, “Timo” or “Mariella”. The abundance of their harvest leaves much to be desired, but when growing potatoes as a way of earning money from selling them early, early maturity is very important. In any case, such potatoes can be planted in small quantities on a personal plot, only for their own needs and to quickly get young potatoes on their table. Speaking about whether potatoes need to bloom, you should know that varieties are classified into those that thrive abundantly, those with average flowering, as well as rare-colored varieties and varieties without flowering at all. For example, potatoes of the “Vesna” variety refuse to bloom in dry years, and at normal humidity they bloom so quickly that many simply do not notice this period..
- Do Colorado beetles eat flower stalks? What this pest looks like is known to everyone who has ever grown potatoes on their personal plot. In addition to the Colorado potato beetle, other insects that are not so widely known can also harm the potato. Most of these creatures do not cause much damage, however, they are not useful either. Among such insects are ground beetles and potato ladybugs. When potatoes bloom, adults of these beetles begin to feed on its peduncles. If a lot of black and small beetles were found on a flower, then it was just the above-mentioned pest that appeared. Large clusters of beetles eat flowers very quickly, and the flowering process itself remains out of sight.
Is the issue of flowering important in growing potatoes?
Whether or not a potato has bloomed this season will not affect the mother plant in any way. Moreover, the flowers of the potato will absolutely not affect the formation of the green mass of the bush or its ability to form tubers..
All the processes that take place in the flower itself are of importance only and exclusively for the fruits of the potato, that is, the berries that are formed after flowering.
Tubers are formed without the participation of these processes, for them they simply have no value. They don’t need fertilization. The tuber itself is not the seeds of a plant in the usual sense of its word, it is just its vegetative part.
Therefore, answering your question – why the potatoes did not bloom, remember that the formation of flower stalks does not in any way affect the yield even before you start to panic. The complete absence or wilting of flowers can signal the summer resident that there is some urgent reason for this phenomenon. Whether it is a plant variety, insects, high temperatures, low humidity or soil depletion. In the case of a decrease in yield, it is not necessary to look for the reason at all in the absence of flowering..
