Characteristics and features of the cultivation of honeysuckle varieties Indigo Gem (Indigo Gem)
The honeysuckle variety Indigo Jam has a lot of attractive characteristics for gardeners. It is one of the most fruitful varieties of honeysuckle and is recommended for cultivation on an industrial scale, since the berries of this variety are distinguished by high taste and marketability.
Bred in Canada. Varietal testing in Russia, the variety took place in the suburbs. Indigo Jam has already managed to earn high praise from Russian farmers, and in the USA the indicated variety is among the top best crops with high production potential.
The main botanical data of the plant:
- bush of medium height, up to 1.5 m, in diameter reaches 1.2 m, V-shaped;
- young shoots are painted in gray-green color, old ones - in brick-brown, the bark is peeling on them;
- foliage green, lanceolate, pointed at the ends, dense in structure;
- flowering occurs early;
- inflorescences, consisting of 2 white flowers, form in the leaf sinuses;
- the berries are large, weighing 1.3-1.9 g each, oval in shape, painted blue.
Did you know? Honeysuckle fruits are an aphrodisiac and also help men eliminate erectile dysfunction.
A distinctive feature of this variety is that the berries after ripening are stored for a long time on the branches, not crumbling. This feature allows the use of mechanical devices when harvesting, which is very convenient when a large number of plants grow on the site. In many other varieties of honeysuckle, the fruits are showered from the slightest blow of the wind.
Knowing the main characteristics of the culture, you can greatly facilitate your work on the site and increase the productivity of your work. Based on this information, you should first of all make a list of advantages and disadvantages, based on which you can correctly select the conditions and terrain for growing. In addition, given the characteristics of the culture, it will be possible to quickly correct deficiencies in care, if any.
Frost and drought resistance
The variety under consideration is characterized by increased winter hardiness. Without shelter, the bushes tolerate frosts well to -35 ° C. Even flower buds do not freeze during return frosts to -8 ° C. The only thing that can negatively affect plants in the winter is a long thaw. Under such conditions, the bushes may “leave” the dormant stage too early.In relation to drought, the crop also has a high degree of resistance. The plant rarely requires hydration, but water should be supplied in large volumes, and only in the driest periods. Indigo jam is rarely affected by diseases and pests.
The variety is early. It enters the fruiting phase in the second year after planting. Berries ripen in the second half of June. The yield of the crop is extended until the beginning of August, as the fruits ripen unevenly.
Important! In conditions of lack of light, Indigo Jem honeysuckle berries are small and sour.
Productivity from one bush per season is about 4-4.5 kg. Berries are distinguished by high taste characteristics. Their pulp is dense, slightly elastic. It has a pleasant dessert, sweet taste.
Advantages and disadvantages
- The culture in question has a lot of advantages:
- high productivity;
- early maturity;
- good resistance to negative factors of external influence;
- unpretentiousness in leaving;
- high taste and marketability of the fruit;
- the possibility of harvesting in a mechanized way;
- good transportability of berries.
Like any other plant, Indigo Jam has its drawbacks.But, compared with the advantages, they are much smaller. In addition, they can be easily eliminated by choosing a rational scheme of cultivation and care.
- The disadvantages of the variety include:
- partial autonomy;
- exactingness to lighting.
The variety is partially self-pollinated. Given this, another variety will need to be planted on the site to increase yield. As a pollinator for Indigo Jam, plants of the Hoynebi or Tundra varieties are well suited. Without the presence of additional pollinators, about 40% of the fruits are tied from all flowers.The main carriers of pollen are bees, bumblebees, and small insects. To attract them during flowering, leaf spraying is carried out with sugar syrup. 40 g of sugar are dissolved in a bucket of water.
Important! When spraying during the flowering period, you need to very carefully handle the bushes and make sure that the liquid does not get inside the flowers. Otherwise, all pollen will be washed away.
If you approach the organization of care correctly, honeysuckle bushes will remain productive for many years. One of the important stages is landing and preparation for it. The first step is to determine the timing of planting and select a nursery where you can purchase high-quality planting material. Then you need to prepare a place on the site, taking into account the requirements of vegetation.
Landing can be carried out in spring and autumn. When determining the period, one should be guided by the climatic conditions of a particular region and the vegetative characteristics of vegetation. Honeysuckle buds begin to swell already in mid-March, and the soil at this moment is warm enough for planting only in the southern regions of the Russian Federation.With this in mind, spring landing can only be done in the south. In all other regions it is better to attribute the event to the end of August - the beginning of September.
Site selection, well preparation
To obtain a full crop, in the volumes declared by the originators of the variety, it is necessary to select the territory that is most illuminated by the sun. In addition, you should take care of natural (trees, shrubs) or artificial (buildings, fences) fencing from cold winds. Given these requirements, the southern or southeastern side of the site, protected from the north from a draft, would be an ideal location.
There are no special requirements regarding soil quality. The main thing is that it has a neutral or slightly acidic reaction, in the range of 5–7 pH. At the same time, the best yield indicators are observed on light, loose, with a thick fertile layer, consisting mainly of organic matter, soils. Type - loam and sandstone. An important nuance when choosing a site is the location of groundwater: they should be no higher than 1.5 m from the surface.
They begin to prepare the territory six months before landing. At this stage, the soil is cultivated to a depth of 40 cm. Disinfection is carried out using 3% concentrate of copper sulfate (300 g of substance is added to 10 liters of water). 1 liter of working solution is enough for disinfection of 10 m². After 7–10 days, they again dig the soil to a depth of 20 cm, after having previously distributed 20 kg of manure, 400 g of wood ash and 10 kg of sand on each square meter. On sandy loamy soils do not make sand.Landing pits are also prepared in advance. This must be done 20 days before landing. It will be possible to achieve high-quality cross-pollination if you arrange the bushes not in a row, but in a circular pattern: in the center - a pollinator variety, and around - 4-5 copies of Indigo Jam. The distance between the bushes should be 1.5 m. The size of the holes is 40 × 40 cm.
Step-by-step preparation of recesses for landing:
- Make a marking according to the scheme described above, dig holes.
- Combine the soil from the hole with 20 kg of compost, 1.5 kg of wood ash.
- Fill the pit by a third with nutrient substrate, form a hill about 10 cm high in the center.
- Cover the wells with a film or tarpaulin so that the formed eminence does not erode before rainfall.
Selection and preparation of planting material
The purchase of plants should be carried out in specialized nurseries. Better and faster in a new place take root instances of 2 years of age. The height of the ground part of a quality seedling should vary between 25-60 cm. It is advisable to purchase planting material in containers. In such plants, the roots do not dry out, like those that are sold with an open rhizome. In addition, this makes it possible to plant plants at any time convenient for the farmer.
If you buy a seedling with an open root, then you will have to plant it within 1-2 days so that it does not deteriorate. The preparation of planting material begins to be carried out a day before moving to open ground. Plants are removed from containers.Rhizomes are freed from soil, which is easily removed, then washed with running water. Inspect the seedlings, cut off dried shoots as necessary. Roots that are longer than 30 cm shorten. Rhizomes are soaked for 18–20 hours in a bath with a growth accelerator. You can use "Zircon" (1 drop of water is 40 drops of the drug).
Previously, before landing, after about 2 hours, cover should be removed from the pits. In the center of the already formed mounds make indentations. Pour 5 l of water into them. After 2 hours, plants are planted. In the recess, you need to place the root system of the seedling, carefully straighten it. Then sprinkle soil into the pit, making sure that the root neck remains flush with the soil.
Filling the pit with soil, the seedling should be periodically gently shaken so that air cushions do not form. After the hole is completely filled, the trunk circle should be sealed and 10 liters of water filled in it. After waiting for the complete absorption of the liquid, the soil around the plants is mulched with compost to a height of 10 cm.
Indigo Jam is completely unpretentious in leaving.
Key activities to consider:
- watering - every 2 weeks, 30 l under the bush;
- loosening - after each rain and watering to a depth of 5 cm;
- mulching - as the layer formed at the time of planting settles, it needs to be updated.
From the second year after planting, fertilizer should be applied. In the spring, before the buds swell, while the soil is still moist, 10 kg of rotted manure is distributed in the near-stem circle of each plant. As soon as flowering is over, wood ash is added to the water for irrigation - 500 g for each bush. In mid-September, 30 g of potassium salt and 50 g of superphosphate are diluted in 10 l of water for each instance.
Another of the honeysuckle care measures is pruning. For this variety, only sanitary manipulations are required, involving the removal of broken, thickening crown, creeping along the ground, branches. When the bushes reach the age of 10 years, a rejuvenating procedure is performed. It involves the removal of all non-fruiting shoots. Any kind of pruning is best done in the fall. In spring, you can adjust the result.
Propagate the vegetation of a given culture in one of 3 ways:
- green cuttings;
- stiff cuttings;
- dividing the bush.
When using the first method planting material is cut from the shoots of the current year. Harvesting of material begins to be carried out after the plants begin to form an ovary. The strongest growths are selected, cut, divided into several segments 12 cm long.Each should have 3 kidneys. For 24 hours, the raw materials are soaked in Kornevin (20 drops are added to 1 liter of water). Then plant the cuttings in the ground, cover them with plastic bottles with a trimmed bottom. Periodically planting moisturize, aerate. After a month, shelters can be removed.
Woody cuttings cut off in late September - early October, after falling leaves. The growths of the current year with 2–5 internodes are selected. Wrap the raw materials in burlap or paper, add them to a depth of 10 cm and cover them with foliage.In the spring, they are planted in open ground at an angle of 45 ° so that only 1 internode remains above the surface.Bush division carried out before the swelling of the kidneys or in the fall, after leaf fall. Dig plants 3-5 years old. Using a secateurs, divide the bush into several parts. The resulting seedlings are placed in prepared pits.
Diseases and Pests
With proper care, the honeysuckle of the variety in question is not affected by diseases and parasites. As a prophylaxis, at the beginning (before the swelling of the kidneys) and at the end of the season (3 weeks before the frost), the bush and soil are sprayed with 1% solution of copper sulfate. Throughout the season, if the weather is too humid, planting should be dusted on leaf and soil with wood ash or tobacco dust.
With improper agricultural practices, powdery mildew may appear on the bushes. This is a fungal disease, which is characterized by the appearance on the leaves and shoots of a whitish coating. When the first symptoms appear, immediately remove the infected parts of the plant. Then spray “Fitosporin” according to the instructions. It is necessary to remove the layer of mulch (completely), loosen the soil to a depth of 5-7 cm.
Did you know? The extract from the fruits of honeysuckle is used to create perfumes of the brands "Adidas" and "Avon".
After that, sprinkle the near-stem circle with sand mixed with peat (1: 1) and wood ash (0.5 kg). Of the pests on the shrub, aphids can settle. To eliminate it, you can resort to dusting the plantings with tobacco dust, having previously removed all the lesions. The soil around the plants and in the rows must be loosened up and replaced with a new mulch.
The winter horticulture variety under consideration does not require shelter for the winter. It is only necessary to increase the layer of mulch in the near-stem circle so that the roots do not freeze. Do this 3 weeks before the onset of steady frost. For the cold period, the mulch layer is increased to 15 cm.
Harvesting and storage
Harvesting is carried out as the fruit ripens. You can collect them manually or using special machines if the plantings occupy a significant area. Immediately, the fruits are placed in small boxes, with a capacity of up to 5 kg, with low sides. Berries are laid in a single layer, previously covering the bottom of the container with parchment.
Harvest is stored up to 7 days at a temperature of +3 ... + 6 ° C and in the absence of light. To extend the terms, it is better to freeze the berries or send them for processing. Of these, you can make various winter preparations in the form of jam, jam, as well as pastille, marmalade and other sweets, liquors.The honeysuckle variety Indigo Jam has a lot of advantages that allow cultivating the plant not only in private farms, but also as an intensive crop for commercial purposes in large farms. Suitable for growing in cold regions of Russia, due to its high winter hardiness.
It seems to me that the taste of some varieties of honeysuckle changes to 2-3 times as it ripens. A special advantage of Indigo Jam is that the berries are not only edible, but also very tasty, just a few days after dyeing, even with acid. This makes Indigo Jam a really early variety, comparable to early strawberry varieties or even earlier. And the varieties that first need to hang for a month in order to gain sugar before real edibility are early varieties are only on paper.
