A unique plant Japanese quince is relatively easy to propagate vegetatively. The source material can be written out by mail from collectors or asked from friends (grafting, grafting). Layers, root shoots to use from their own instance. Let's consider each method in more detail
Root shoots
New shoots are formed around the mature bush, coming from the roots. They are suitable for further reproduction. To form a good underground part, during the summer, the young are huddled several times to a height of 10 cm. Moisten the embankment as it dries. In autumn, seedlings with a powerful root system are dug, with a shoot length of 15-20 cm, a thickness of 0.6-0.8 cm.
Young plants with a clod of earth are planted immediately to a permanent place. They spill well at first. Humus is scattered around the mother bush, restoring a flat surface. Abundant moisture removes voids in the soil.
Cuttings
When cuttings, the varietal properties of plants are preserved. 3-4 cuttings are obtained from one branch. The starting material is harvested in early summer in the morning before the onset of heat. Sticks with 2-3 buds are cut. The lower leaves are removed completely, on the upper ones, we reduce the leaf plate by half.
On the cuttings taken from the top of the shoot, they grab a 1 cm piece of last year's wood. An oblique lower cut is dipped into Kornevin powder. Shake off the excess amount of the drug.
Prepare a bed of humus with sand. Cut grooves every 25 cm. Spill with potassium permanganate solution. Prepared cuttings are planted obliquely at an angle of 45 degrees with respect to the surface. Install containers with water, cover with foil to create a greenhouse effect.
With a favorable outcome, after 1-1, 5 months, the kidneys start to grow. The yield of finished seedlings is 70-80% when using a root formation stimulator. Without additional preparations, the number of quality seedlings is reduced to 30-50%.
By the end of summer, the shelter is gradually removed. The next spring, the young are transplanted to a permanent place.
Graft
The starting material is twigs from varietal large-fruited specimens (scion). Suitable as a stock: wild quince or seedlings grown from seeds, three years old. Experienced gardeners graft chaenomeles on closely related crops: hawthorn, spiked irga, rowan, pear.
The winter-hardy base makes it easier for the quince to tolerate significant drops in temperature in winter. The inoculation is placed at a height of 30-50 cm from the ground in order to protect the cultivated, young shoots from frost.
In the spring, before bud break, use the copulation method. Twigs with the same diameter are selected. Form an oblique cut. Combine the scion with the stock, combining the bark. Wrap with a strip of polyethylene, capturing an additional 3-4 cm above and below the cut. Secure the end with a loop.
At the same time, they are inoculated with the rotary method. The crown on the rootstock is removed at a right angle, the middle is split. The graft is cut from two opposite sides at an angle, forming "shoulders" in the upper part. The branches are connected, combining exactly the wood. Wrap the back of the tape (sticky layer out).
In the middle of summer (July) they are engaged in budding "with an eye". On a varietal branch, a bud at the base of the leaf is cut off with a small amount of bark. The bark is cut into the rootstock in the form of the letter "T". Neatly fold back the edges, insert the scion. Wrap with sealing material.
With a positive result, after a month, the kidneys start to grow. For protection from the wind, young shoots are tied to a support fixed on a bush. In the fall, the winding is removed. All buds below the varietal stem are harvested at the time of leaf blooming. The operation is carried out regularly as it grows back.
Layers
The lower branches of the bush are laid in prepared grooves to a depth of 10 cm. They are pinned with wire, the end is tied vertically to a peg. Moisten the trench, cover with fertile soil, mulch with sawdust.
Keep the soil moist throughout the season. By autumn, a branched root system is formed in the underground part. In the spring of next year, the plants are ready for transplanting to a new site.
Shoots are cut from the mother plant. Dig it carefully, trying not to damage the earthen lump. Transferred to prepared pits. With this method, 2-3 seedlings are obtained from one bush.
We will consider growing techniques in the next article.
