In almost every suburban area, you can find walnuts. It is grown not only for the benefit of the body, but also for decorating the garden. When the plant begins to bloom, the site immediately acquires an unusual appearance and attracts the attention of others.
How a Walnut Tree Blossoms
If you want to observe how the walnut blossoms annually, you need to plant a tree on your site.
Did you know? In the Caucasus, walnuts are considered a sacred plant. In this area, trees grow, whose age is more than 400 years.
Walnut Flowering Forms
It is impossible to determine exactly how flowers form on a tree. In total there are 2 forms of flowering. The reason lies in different varieties. Depending on the variety, flowering is distributed into protoginic and protandric forms. The tree is characterized by the presence of male and female flowers. The first look like earrings. On the top of the shoot are female flowers in the form of a pestle, and their number reaches 2–4 pcs.

The main difference between the forms is which flowers bloom first. In protoginical form, male inflorescences first bloom, and then female ones. There is a possibility that after flowering the tree may not bear fruit. This situation occurs when male inflorescences are revealed, and female not.
This form is fundamentally different from the first. In this case, female flowers bloom first, and then male flowers. It is likely that in this case, problems with fruiting may occur. If female inflorescences crumble before the male earrings bloom, then the ovaries will not form.
Important! Based on this feature, a nut tree needs a partner. His flowering time for female and male inflorescences should coincide.
What month does walnut blossom in?
The flowering of walnuts begins in late April. The process continues until early May. Duration is approximately 2 weeks. The first flowering occurs 3-4 years after planting. Once the nuts are pollinated, fruits will form.
The fertilization rate depends on the pollination range. The process is negatively affected by the thickening of the crown of the tree. Other causes that slow or hinder fertilization include:
- low or high humidity;
- weak wind blowing;
- frequent and cold rains.
How and when does a walnut fruit form
A phased description of the formation of the nut fruit:
- The seeds are covered with a green shell. It is formed from bracts of flakes and petioles of leaves for an embryo.
- The surface gradually becomes dense.
- Internal cotyledons develop.
- After ripening, the shell cracks.
The fruits begin to set after flowering, that is, their formation and development occurs in the summer.
Proper Nut Care
Walnut cultivation is not only a quality planting. The most basic thing is leaving. The tree needs top dressing and watering. All other stages of care can be used by the farmer at will.
Did you know? If you exceed the daily norm of a walnut, then you can provoke a mouth rash, headache, spasms in the vessels. In some cases, this leads to enlargement of the tonsils.
Watering should be plentiful. During the first years of life, plants contribute water with an interval of 2 weeks. Especially if drought prevails in the spring-summer period. 3 buckets of water are used for 1 plant. When the tree reaches a height of 4 m, watering is carried out 1 time per month, using the same volume of water.
Top dressing is applied twice a year. In the spring, nitrogen substances are used (600 g per 1 plant). In summer, it is necessary to use potash components (400 g per 1 bush). In the fall, during plowing, use phosphorus fertilizers (900 g of phosphorus per 1 tree).
Important! Remember to regularly loosen the topsoil and remove weeds so that more nutrition and oxygen enter the root system.
- ammonium nitrate use 7 kg;
- potassium salt - 2 kg;
- superphosphate - 10 kg.
Walnut pests and protection against them
The main pests of walnut include the moth, white butterfly, walnut moth and warty mite. In the fight against these parasites, you need to use strong chemicals that spray with an interval of 3-4 weeks.
Symptoms of moth damage include darkening of the nut fruit. They also fall off before the time comes. Against the moth, it is necessary to use the preparation "Strobi" (50 g per 10 liters of water). The harm from the white butterfly is that the parasite eats shoots and leaves. A greater number of pests can provoke the lack of deciduous cover on a tree. In the struggle they use Vectra (60 g per 7 liters of water).
To determine the presence of a nutty moth, just look at the leaf cover. On its surface there should be small dark tubercles. “Lepidocide” (100 g per 4 l of water) is used against the parasite. If dark tubercles similar to warts appeared on young leaves, then the tree is affected by a tick. Against it, it is advisable to use a solution of "Bitoxibacillin" (200 g per 10 liters of water).
So, now you know how a walnut blossoms and develops. It is not difficult to cultivate it, if you follow all the basic rules for care. The more effort you put into the development of culture, the more likely it is to get a quality crop.
