Actinidia, from the Latin Actinidia, belongs to the genus woody vines of the family Actinidia (Actinidiaceae). Among the most popular in the home gardening of our country are plants of the Kiwi species, or Delicious Actinidia. They propagate quite easily, and seedlings independently grown by gardeners retain all varietal characteristics of the culture. Seedlings obtained by vegetative propagation enter fruiting in the third or fourth year after planting.

Preparatory work

Actinidia is quite simply propagated by seeds, horizontal layers and green cuttings. You can carry out the procedure in the spring or in the fall.

Propagation of actinidia by cuttings makes it possible to obtain a large number of high-quality seedlings in a short time. Carrying out this procedure in the early spring period requires preparatory work.

When propagating by woody cuttings, cutting of planting material is carried out in the winter, even before the stage of spring movement of plant juices. The ends of the cuttings are treated with paraffin, and then the material is laid until it is planted in moist moss. In the spring, cutting into cuttings suggests the presence of two or three buds on the planting material. Prepared cuttings should be kept for some time before planting in a solution of "Heteroauxin" or any other root stimulant.

If annual green cuttings are used for propagation, then cutting is carried out directly at the base of the shoot. Then the planting material must be lowered into a container of water. As a rule, shoots are cut off in the middle of the first summer month. It is very important to remove 50% of the leaves on the cuttings, which will reduce the evaporation of moisture.

Seat selection

For the cultivation of liana plants in the garden, it is very important to choose the right site for planting. Actinidia grows, blooms, and bears fruit in one place for thirty or more years. The plant will need a fairly reliable and durable support.

For large plants, planting plants such as actinidia is not recommended. It is also very important to remember that it does not tolerate the neighborhood of fruit trees such as apple trees, but grows well next to currants. You can not plant actinidia next to garden plants that need annual deep digging in the trunk circles. Optimal is placement along hedges or buildings, which will allow the liana to rely on ladders, picket fence or trellis.

Soil requirements

For the cultivation of actinidia, you can use areas with a variety of soils, with the exception of flooded or clay soils with too close a location of groundwater. The main requirement is that the site has good natural drainage.

Actinidia survives best when planted on hills or slopes with the possibility of runoff melt and rainwater. The plant is characterized by intensive growth of the aerial parts, so it is advisable to devote soils rich in organic matter, with weakly acidic or acidic pH values. Important to rememberthat for planting, lime or potassium chloride should not be added to the soil.

Landing technology

After soaking, green cuttings should be placed in seedlings filled with moist moss and a mixture of soil with humus and a few centimeters of sand, which should be poured over the resulting composition. The lower part of the shank must be deepened in sand at an angle of 45 degrees, and then the beds need to be abundantly watered. To create a greenhouse effect, planting should be covered with a film. It is necessary to monitor humidity indicators and maintain the temperature regime at the level of 22-25 ° C. Under such conditions, rooting takes about three to four weeks, after which it is planted on a permanent place in open ground.

Landing pits or trenches should be prepared in advance. The standard width of the landing pit is 0.55-0.65 m with a depth of 0.45-0.55 m. The distance between the pits cannot be less than two meters. At the bottom should be laid drainage layer, represented by pebbles, broken bricks or stones of medium size. Then you need to make about 2/3 buckets of organic fertilizers in the form of humus, peat or compost with the addition of 0.15 kg of ammonium nitrate, 0.25 kg of superphosphate and a small amount of wood ash.

A layer of fertile soil should be poured onto the drainage layer, and then a mound of fertilizer with garden soil should be made. On it, you need to distribute the root system of the plant. Do not deepen the root neck of actinidia. After planting, you need to carry out abundant watering of plants based on a pair of buckets per vine, and then mulch with peat or compost.

Care Rules

Activities for the care of actinidia at the stage of active growth are simple:

  • weeding the area around the plants;
  • timely conduct of irrigation activities;
  • pruning of the crown of the plant;
  • systematic fertilizer application;
  • prevention of diseases and pests.

For hydration, it is recommended to use the airborne method, which consists in morning and evening spraying of actinidia, which is especially important in dry and hot periods. The soil around the plant should be loosened after watering, but very carefully and shallow, with the simultaneous removal of weed vegetation.

In order to increase the indicators of frost resistance and plant productivity, as well as to stimulate the growth of new shoots, it is very important to fertilize with quality mineral complexes. Early spring top dressing involves the introduction of approximately 33-35 g of nitrogen-containing, as well as 20 g of phosphorus and 20 g of potash fertilizers. Second feeding should be carried out at the onset phase, using 15 g of nitrogen, 10 g of phosphate and 15 g of potash fertilizers per square meter. Third feeding produced in the last decade of September with the addition of potassium and phosphorus. All dressings should be accompanied by abundant watering.

Useful properties of actinidia

In order to obtain the most decorative and productive plant, as well as to avoid excessive thickening of the crown, a shaping pruning of actinidia should be carried out after the plant reaches the age of three to four years. Also, preventive treatments with special insectofungicides cannot be neglected.
