Why gladioli degenerate and turn white


Garden plants

The development of new varieties of gladioli for the breeder becomes a matter of his whole life. The path from seed to registration of a new variety is usually more than 10 years. All this time, there is an observation of how the hybrid behaves, all changes that occur to the plant and all its characteristics are scrupulously recorded.
In order to say with confidence that the resulting hybrid has a complex of unchanging, inherent only qualities that are stable, inherited from year to year during vegetative reproduction, it must be observed for 10-12 years.

Breeding new varieties of gladiolus

Complexities of the process

Not every seedling that has emerged becomes a variety. Selective selection proceeds as in gold mines: one grain of gold per ton of sand. And only after making sure of the stability of the traits experimentally, the hybrid can be called a variety. This has always been the case in our country. Abroad, they also adhered to these principles for the time being.

Why not grade?

Everything has changed in recent decades. The pursuit of quick profit dictated its own conditions, therefore, one-day varieties appeared on the flower market, which received the common name "Dutch", but they cannot be called varieties either. In fact, these are hybrids, but their variety trials are carried out not by breeders, but by buyers, who are very surprised to see that the blossoming flower does not at all look like the one drawn on the label. And the sellers answer that they again received a re-grading instead of the gladiolus declared on the labeling.

Indeed, re-grading happens, but at the same time any plant tends to return to parental forms and qualities. And as a result, from the hybrids that did not pass the variety testing, flower growers have pink gladioli, which they never acquired, or white, or red ones, but not at all what they paid for.

Why did everyone turn white?

But sometimes the reason for this behavior of gladioli is completely different: the flowers are not planted in groups of varieties, but as necessary, in different places, without markings. During random storage, the bulbs inevitably deteriorate for various reasons, and it is no longer possible to find out what varieties they were. Disease resistance in different varieties is also not equally strong. The fittest survive, and it is likely that only one variety will remain as a result. And careless gardeners complain that gladioli have become dusty and all of the same color.

Do gladioli get pollinated?

A change in the qualities of a variety during cross-pollination is possible only with seed reproduction of gladioli, and amateur flower growers usually propagate this culture vegetatively. To protect yourself from such "surprises", pay attention to the varieties of domestic selection that have passed all stages of variety testing and registered with the appropriate authorities with the assignment of a name and a standard code.

In addition, so that the collection of gladioli does not degenerate, it is necessary to systematically replace old corms with young ones grown from children.

Why does the bark of trees burst?

Why does the bark of trees burst?

Sometimes from a sharp fluctuation in moisture in the soil. It was dry for a long time, and then you took and immediately made abundant watering. But more often this phenomenon is associated with a sharp fluctuation in air temperature in early spring, when, after prolonged warm weather, severe frosts suddenly set in.

Cracks should be washed with a light pink solution of potassium permanganate (hydrogen peroxide, brilliant green) and covered with liquid pitch.

Can be coated with clay with a mullein and tied with burlap. The bark will grow together.

Most importantly, do not postpone this work indefinitely, because pathogens will penetrate the crack, settle on the wood, and then peeling of the bark and its death cannot be avoided.

This text is an introductory fragment.


What to do to prevent this from happening

If the problem is physiological, it can be easily corrected by taking the following measures:

  • to establish agricultural technology on the beds, especially by normalizing the irrigation regime
  • limit the feeding of bushes with nitrogen
  • choose complex fertilizers with a high potassium content
  • making sure of the deficiency of minerals, potassium nitrite or monophosphate is introduced into the soil; chemicals can be replaced with a folk remedy - ash infusion (6 glasses of powder per bucket of water)
  • ash can be simply sprinkled in the beds next to the bushes
  • if tomatoes are grown in a greenhouse, then it is reasonable to whitewash the glass roof in the building.

Having discovered the signs of a viral disease, the problem will have to be solved radically. Phytoplasmosis cannot be cured, so all diseased plants are removed from the garden and burned outside the site.


Preparing the bulbs

Bulbs extracted from the ground should not be cleaned of scales and earth. They are placed in their original form in baskets or other containers that are well ventilated. You need to dry them in a dry and warm place for a week. Suitable for this:

  • veranda
  • ventilated barn
  • canopy
  • alcove.

Avoid direct sunlight on the planting material. After a week, the tulip bulbs must be cleaned of integumentary scales and roots, removing damaged or rotten ones, and sort the remaining ones by varieties and sizes. If there are minor injuries, then they are removed with a sharp knife and washed. After that, the planting material is recommended treat with contact fungicides or a solution of potassium permanganate to protect against fungus and rot. It is best to store bulbs in wooden boxes in one layer.


My love for roses is serious and for a long time! Only for some reason, somehow I was not interested in climbing roses, but this spring I caught fire to put an arch in front of the entrance to a separate part of my garden and plant climbing roses on both sides of it, which look so beautiful on pictures on the Internet. Thanks to long flexible but strong lashes, such roses can be woven into a support and they will perfectly frame it. The choice fell on Schneewalzer from Tantau. I bought this rose at IM Garshinka for 350 rubles. You can see in that review in what condition and how my roses came to me. So, everything in order.

Description of the variety

This beautiful climbing rose is popular in western Europe and Scandinavia. Schneewalzer has large flowers, shaped like hybrid tea roses. Barely opened, they are very pale lemon, with a pearl pink center, later turning pure white. They usually appear one at a time on long stems, sometimes 2-3. Shoots with flowers are not rigid, but gracefully bend to the sides, and the flowers droop, so that they can be clearly seen from below. The foliage is dark, resistant to diseases, the bush is vigorous, branched. Flowers are densely double, appear almost without interruption all summer. They are damaged by rain. After the first abundant flowering, only individual flowers appear; in wet weather, buds may not open.

Climbing roses are long. Schneewalzer reaches a height of 2-3 m, a width of 2 m. My rose in the first year is much, much more modest - only 0.5 m in height and the same width. The foliage of the rose is luxurious. As she planted, she immediately went into growth, throwing out three lashes. I already woven one of them into the arch, but after flowering. I don’t think that this year it will grow decently, but all because of the rain, lack of heat. I believe that by next year it should take root decently and will grow a good green mass next spring. I'm not offended. While she goes for my usual park rose.

The Schneewalzer flower is just a fairy tale. Without exaggeration, I call her THE MOST BEAUTIFUL WHITE ROSE. Her flower is tenderness itself in its purest primordial form. Pure white, with a lemon center, an elegant glass, slightly drooping and this is its charm. You get a kind of 2 types of flower over time:

... in half-dissolution - the countess, in full dissolution - the empress.

With this disease, strawberry leaves also become covered with dark spots, gradually interveinal necrosis develops on them. First of all, the old lower leaves dry up, and then the whole plant gradually dies. If the disease spreads to the root system, the roots turn into dry rot. In place of diseased plants, new strawberry bushes cannot be planted, since the fungus remains in the soil.

There are two forms of this disease: transient and chronic. In the first case, at the beginning of the growing season, the peduncles or the entire bush wither, the roots are bare, and in the longitudinal section they acquire a reddish tint. In chronic fusarium disease, diseased plants lag behind in growth, the leaves become smaller, acquire a cupped shape and a grayish tint. Gradually, the leaves dry up, the peduncles are shortened, the mustache rarely appears, and the berries are not tied. The plant dies 2-3 years after infection.


Varieties of my selection

First of all, I would like to note the cultivar Mamin Rushnik 501-DR-SG 2008. It attracts attention with large white flowers with a barely noticeable shade of ivory, elegant intensely wavy corrugation of the perianth. This gladiolus has two-row inflorescences of the classical form with 24-26 buds, of which about ten are open at the same time. A large velvet coral spot, more intensely colored in the center, on the lower petals, gives the flowers a special tenderness. The inflorescence is very decorative, with a harmonious combination of white, dark and light coral shades. Peduncles are very tall, resistant to adverse weather conditions (sunburn and rainy weather). Cut flowers tolerate transportation well.

The variety belongs to the very early group, in which there are not many varieties with a long spike, bearing a large number of flowers. The cultivar forms a lot of medium-sized children, which, with good agricultural technology, in the first year after sowing, can form corms of I parsing and bloom in late August - early September. On an adult corm I parsing, 3-4 full-fledged peduncles can form. In this regard, the flowering period becomes longer, and the amount of flower production when growing a variety on the same area can be doubled.

Another cultivar, which can be safely attributed to the group of industrial varieties, is Churaivna 520-С-СГ 2007. It has excellent adaptive properties, rather plastic. Shows its decorative qualities even in very hot weather. It multiplies well, forms a lot of large babies I parse, which can bloom in the first year of cultivation. In addition, this cultivar is resistant to common diseases of gladiolus, its perianth tissues are very dense, slightly damaged by gladiolus thrips. The variety keeps well in winter. But most of all, this gladiolus amazes with delicate pastel shades of flowers in a creamy-pale palette with very strong corrugation and long lilac stamens, giving the inflorescence a special expressiveness and elegance. The flowers are large, the corrugation is very exquisite, as if lace frames the edges of the petals, which at the ends become lighter and more iridescent. Flowers look great both in cut and in a flower garden. The spike is two-row, has more than 24 buds, about 10-12 flowers are open at the same time.

It is always difficult for breeders to get the emerald color of gladiolus. I managed to create an interesting cultivar Esmeralda 502-P-SG 2007. The variety belongs to the early group. The flowers are light-green when dissolved, then the two lower petals brighten a little, a barely noticeable red flare appears in the throat. The perianth is folded-corrugated, very dense (this is rare in green-flowered varieties). Differs in good growth qualities, reproduces well, is relatively resistant to diseases and is slightly affected by gladiolus thrips.

As a result of painstaking work, an interesting cultivar Pasadoble 554-R-G 2007 was selected. Its flowers are with a bright dark red color and a white border around the edges of all petals, a very dense texture of the petals and beautiful corrugation. The variety is grown for cutting, but it is also very effective in a flower bed.

This year, another novelty for the cut with a late flowering period appeared - the Sivash 454-P-G 2016 variety. This is a moire brick-red gladiolus with a white thread-like edging on all perianth lobes and small red arrows on the lower three lobes.

Excellent economic and decorative qualities are possessed by the variety with a pink corolla Romantica 441-R-G, 2009. In all weather conditions it grows slender, even, reproduces well, is resistant to diseases, gives a first-class cut and can be recommended for growing in all soil conditions. climatic zones.

The exotic variety Perlyna 542-P-SSG 2009 has also proven itself well. It has already become my “calling card”. The flowers have shortened petals of the inner circle of the perianth and wide elongated petals of the outer circle, which, in combination with wavy corrugation in the form of wide folds and pink highlights on a white-green background, creates a flower-within-a-flower effect. The petals are light pink, closer to the edge, the color intensity increases, smoothly passing from the white throat to the nacreous pink edge of the outer perianth circle. All petals are framed with a bright green scalloped border. Inner shortened petals with fantastic corrugation also create the illusion of a double perianth. The flowers are greenish-pink when dissolved, and over time they acquire a pearlescent sheen due to the very dense silky tissues of the perianth and unusual corrugation. The inflorescence is two-row, consists of 22-25 buds, 10-12 flowers are open at the same time. The variety reproduces satisfactorily and gives a large baby.

The group of sky-blue and blue gladioli in my collection is represented by such cultivars as Blue Valley 580-С-СГ 2007, Zoryana Nich 583-Р-СГ 2010, Melody Pidnebesya 485-С-СГ 2015, Blakytny Pavych 575-С-Г 2007. They fully meet the requirements for modern varieties.

To date, it has been possible to create and select up to two dozen promising gladioli cultivars. Every year I demonstrate the results of my work at exhibitions of gladioli, which are held in the National Botanical Garden. N.N. Grishko NASU. Both guests and exhibitors always speak positively about the presented items. I am happy to share my experience with amateurs and professionals in social networks, on the Facebook page of the Gladioli Without Borders public organization. I rejoice from the bottom of my heart when I see that the popularity of my favorite culture is growing.
