The woody actinidia vine is attractive for its tasty fruits with a high content of ascorbic acid, unpretentiousness (planting and caring for it are not difficult), longevity (lives up to 40 years). In the temperate zone with cool summers and cold winters, many garden varieties of actinidia (colomikta, argut, polygamous, purple, etc.) have successfully taken root.

Planting Actinidia seedlings
If you decide to plant actinidia on your plot, then sprouts obtained by cuttings should be used (actinidia grown from seeds lose their varietal characteristics). You can grow seedlings yourself, and you can buy in a specialty store. When buying Actinidia seedlings, two things should be considered:
- How was the escape (if the shoot grows from the bud - it is obtained from the seeds, if a short trunk with side shoots - the shoot is obtained by propagation from the cutting).
- What floor is the plant (actinidia is a dioecious culture, so for fruiting it is necessary to buy seedlings of both sexes).
Optimum landing times
Cultivation of actinidia depends largely on the time of planting. Among gardeners there is no unity on the issue of optimal timing. There are several options:
- early spring, before the juices began to move;
- the end of April - the beginning of summer (after the end of flowering);
- autumn (at least two - three weeks before the start of frosts).
Soil composition
Actinidia prefer acidic and slightly acidic soils (pH = 4 - 5), but grow well on neutral (with good fertilizer). The least suitable clay soils with high groundwater levels. A necessary requirement for successful growth is that the soil for actinidia must have good drainage. It is advisable to plant plants in elevated areas with natural flow.
When planting actinidia in advance (two weeks), you need to prepare landing pits (when decorating walls - trenches):
- 0.5 m - width, length, depth (trench length depends on the length of the wall);
- drainage (brick chips, pebbles);
- over the drainage - enriched soil (humus (bucket), charcoal (50 gr.), superphosphate (250 gr.).
Good predecessors and neighbors of actinidia
The best predecessor is black currant (it loosens the soil, does not deplete it). The choice of "neighbors" due to the usefulness of the plant for actinidia. Beneficial effects provide:
- legumes - beans, beans, peas (improve the soil, maintain the desired moisture balance, improve the microclimate);
- black currant, filbert;
- flowers - petunia, gerbera, calendula, aster, etc. (do not dry the soil, decorate).
- adult fruit trees (especially apple trees). Trees sap the soil with their roots. Digging the near-stem circle is dangerous for the roots of actinidia. The described plant can climb tens of meters up and braid trees, making it difficult to collect fruits;
- young fruit trees (may die from the "hugs" of lianas).
Correct fit
Before planting, seedlings of actinidia are prepared as follows: pruned dry or broken shoots, roots are dipped into a clay mash, a pail of water is poured into a pit.
The root neck should be flush with the ground.It is necessary to make sure that no voids are formed, to trample the ground a bit and to mulch with organic matter.
For fruiting for every three female plants should be one male. The distance between the seedlings when planting is at least one and a half meters. Upon completion of planting, it is necessary to water the sapling with 2 - 3 buckets of water and close it with direct sunlight with gauze, paper, etc.
Basics of Actinidia Care
Proper planting and the complete absence of pests facilitate the care of actinidia. For better growth of the plant and increase fertility, it is advisable to provide it with supports - trellis (galvanized wire between the posts).
Watering and fertilizing the soil
Watering actinidia - moderate. Excessive moisture should not be allowed (the indicator is the ground at the roots).All actinidia love spraying leaves with water dust (morning and evening).
Fertilizers are selected according to the preferences of the plant (slightly acidic and acidic soil) - potassium chloride, ammonium sulfate, ammonium nitrate, wood ash, etc. Chlorine-containing fertilizers are strictly contraindicated, such as lime and fresh manure.
Before feeding actinidia in the spring, after the snow melts, it is necessary to gently loosen the ground near the roots (3–5 cm). Digging is impossible - you can damage the roots. Feeding is necessary:
- at the beginning of spring (they mulch with organic matter and fertilize - for every square meter - 35 grams of nitrogen, 20 grams of phosphorus or potash fertilizers);
- the middle is the end of spring (formation of ovaries) (15-20 grams of nitrogen, 10 grams of phosphate and 10 grams of potash supplements per square). In the summer you need to constantly monitor the root neck, fill the ground when it is exposed;
- at the end of the harvest, before winter. Creepers are fertilized with superphosphate and potassium chloride. The roots are additionally covered with a layer of peat and leaves.
How to trim
Actinidia care involves regular pruning.. Pruning is necessary for a young liana (for its proper formation) and for an adult plant (the constant growth of the liana leads to thickening, darkening, and lower yields).
When planning pruning, consider the following:
- The best time for the procedure are summer months, immediately after the end of flowering;
- in the fall, about a month before frosts (in different regions the time of frosts may vary) - pruning is not recommended (awakened buds and young shoots will not ripen and the frost will kill them). In the southern areas, sanitary pruning is carried out after the end of leaf fall;
- in early spring (when the juice is moving along the vine) pruning is prohibited - any violation of the integrity of the plant is fraught with its death.
- first year - cut the aboveground part, leaving 2 - 3 buds;
- second year - cut off all the shoots, except 2 - 4 vertical (sleeves). After the end of the leaf fall, their apical buds are cut off;
- the third year - the strongest side shoots are selected and tied to the left and right trellis;
- fourth and fifth year - further garter of the strongest and most fruit-bearing branches, pruning of weak, thin, broken and non-bearing trees.
Winter hardiness of actinidia
Actinidia varieties grown in our latitudes have a fairly high frost resistance (colomicta can tolerate frost down to -35 ... -45 degrees ° C).The first 2 - 3 years of life, young plants for the winter is better to cover with a pillow of leaves, spruce branches or polyethylene.
It is not cold temperatures in winter that are most dangerous for vines, but spring frosts (young shoots of actinidia, flower buds and buds are most sensitive to them). Reducing the temperature below zero by 8 degrees can destroy a young shoot.
Planting an actinidia near a residential building partially neutralizes the danger of frost, but a problem may arise from the flow of rainwater from the roof.
Harvesting and Storage
Actinidia brings the first fruits to achieve three to four years of age. Plants of seven years old and older bear fruit regularly (one actinidia can produce from 12 to 60 kg of yield). Harvesting begins at the end of August and continues until frost.
The term of ripening berries of different varieties of actinidia is not the same:
- colomikta - in the middle of August (fruits ripen unevenly and some of them can crumble on the ground). Green fruits can ripen in heat after removal from the vine. For transportation and storage, it is better to pick slightly greenish berries;
- argut and Giralda - the beginning of September (they acquire a bright green color and tender flesh);
- polygamy - September (the color of berries - from yellow to orange);
- purple - the end of September (the berries are not showered, purple).
Fresh fruits are best kept in cool, well ventilated rooms (they strongly absorb odors).
- frozen (wash berries, wipe and freeze);
- dried (washed and dried in the oven (55 degrees);
- as raw jam (ground berries with sugar - 2 to 3);
- dried (washed berries poured with hot syrup, heated for 7 minutes, drained syrup, berries dried in the oven for 15 minutes at 80 degrees.
Reproduction actinidia
Propagation of actinidia is quite simple. Vegetative reproduction has advantages - it conveys the characteristics of the variety, sex, and fruiting on the 3rd - 4th year. Seed propagation provides an opportunity to get more hardy plants, but fruiting - from 7 years of age.
Root offspring
Propagation by root offspring is applied to actinidia polygam and colomicta.
Green and lignified cuttings
Description of the methods of vegetative propagation of actinidia, one must begin with the fastest and most common - grafting. This method allows you to inherit varietal characteristics and get a lot of seedlings. Used two options - green and lignified cuttings.
Green cuttings (the upper part of the shoot from 10 to 15 cm) are stored in late May - early June (when flowering ends): a cutting with two - three buds and internodes. The lower cut of the stalk should have 45 °, the upper - straight. Stalk:
- they plant for rooting in the planting pit with the substrate (drainage, 10 cm of a mixture of humus with sand and 5 cm of river sand), are kept under the film, sprayed twice a day;
- after 30 days they begin to air, from August they open for the night;
- for the winter they cover with a pillow of leaves, in the spring - they transplant.
To increase this index, the kilchevania method is used (a month before planting, cuttings are placed on the ice with the upper ends and closed - the development of the buds stops. The lower parts are warm. After 30 days the roots appear, then the cuttings are planted in the open ground).
Bushes division
The division of the bushes is rarely used in home farms as a method of reproduction of actinidia, but if there is a bush plant on the site (it grows on poor soils, suffered from frost, without support, etc.). Shrubs are divided after leaf fall before frost or in early spring before the movement of juices. Each part of a divided bush should carry stems and roots at the same time.
Breeding taps
The method of reproduction by layering is simple and effective. Under the liana they dig out grooves (7-10 cm deep), the soil in the grooves is mulched with humus, peat, sawdust.
Care for actinidia during breeding by spring taps includes laying the grooves of the lower young shoots, fixing them, falling asleep in the soil and regular watering. The tip of the shoot remains above ground. Layers are separated the following year.
Seed propagation
Actinidia from seed germinate difficult. Therefore, in order to speed up this process, the method of stratification is used:
- washed and dried seeds should be placed in a caprone and soaked in water for 4 days, then buried in sand (in a box);
- box to keep warm for 2 months, sand watered. Once a week for 5 minutes from the sand to get the seeds for airing;
- after that, the seed box should be wrapped in a cloth and kept cold in the street for 2 months;
- At the next stage, the seeds are placed in a cool place (not higher than + 12 ° C), watered and aired once a week. After 20-25 days, their cracking begins;
- It remains to plant seedlings in seed containers (ground with perlite 1x1), and with the advent of the third true leaf transplanted into the ground.
