Reproduction secrets of remontant raspberries

Few people are absolutely indifferent to such a berry as raspberry. When it comes to its types, you should know that the reproduction of remontant raspberries is achieved thanks to special care.

Agrotechnical techniques to accelerate reproduction

The repairing raspberry differs from other varieties in the following feature - with the help of the usual methods of care, its reproduction is like a too useless process. But this is only one minus of the variety and one should not abandon the idea of ​​growing it because of it. Gardeners may face another problem - a small number of shoots, and therefore planting material. But accelerating the reproduction process of remontant raspberries is a real challenge. A number of agricultural techniques can help with its implementation.

One of these methods is to remove during the fall or spring a part of the shoots equal in diameter to 10-15 centimeters two years after planting. Parts are removed from the center of the bush. This procedure will cause the raspberries to produce more new offspring from the remaining roots next year. There will be about 2 dozen of them or even more. They are perfect as planting material.

The second agrotechnical technique is reproduction with the help of green cuttings growing at the rhizome. They have good nutritional qualities and also have excellent growth qualities. More than others, raspberries accept those shoots that have an aboveground part in height equal to 5 centimeters, and part of the shoot is located underground. It is not necessary for them to have a formed leaf outlet. To carry out the separation, they do not need to be dug out, it is enough just to carefully cut with a knife 3-5 centimeters deep. After the shoots are placed in a greenhouse to root, and sometimes shade.

The best time for harvesting is the morning of the last days of spring. The rooting procedure is carried out for about 15-20 days, then the shoots need to be transplanted to a growing area, or in a one-liter container.

One of the best ways is to propagate the remontant raspberry with green root suckers. To do this, you need a stem in height equal to 5-20 centimeters with leaves. In this method, the shoot is transplanted immediately to a permanent place of growth, while removing a third of the leaves from it. It is equally important to organize shady conditions for the seedling for 10-12 days.

To carry out propagation by root cuttings in late autumn, you will need to prepare roots with a diameter of 1.5 mm. Of these, we cut the cuttings of 7-10 centimeters.

The cutting itself is planted 2-3 centimeters deep on a site that is fertilized in advance. Then you need to water, mulch and cover new plantings with coniferous spruce branches.

The arrival of spring for the gardener means time to remove the shelters from the plants and cover the planted cuttings. The film is removed after the appearance of green offspring.

During a leisurely and correct approach to the reproduction process of remontant raspberries, in almost a few years it will be possible to plant the entire plantation, which will bring its owner excellent harvests of the most useful and sweet berries. In general, micropropagation is an excellent way out of the situation when a remontant raspberry variety is grown, which in itself is not very productive.

Propagation by green cuttings

It will be appropriate to dwell on the propagation method using green cuttings and consider its features more carefully.

While most of the berries require green cuttings taken from not yet lignified annual shoots, remontant raspberries need cuttings, the lower part of which is bleached (the one that was underground during the growth of the berry), and the upper part is green. They belong to young offspring. The best cutting is also the one that has risen about five centimeters above the ground. Its foliage should be bronze or red (closer to dark crimson), which indicates its underdevelopment.

The stalk must be cut, pulled out of the soil and rooted in the greenhouse, adding peat and coarse river sand along the way. In addition, the bottom should be treated with charcoal. Cuttings should be planted according to the 5 x 10 centimeters scheme.

In this case, the planting depth should correspond to the depth from which they were extracted. If the soil of the planting is sufficiently moist, and the air temperature fluctuates around 18-25 C, then the cuttings can confidently take root in about three weeks.

Since the reproduction of remontant raspberries requires constant monitoring, then with the beginning of the growth of the cuttings, it is necessary to feed them with a fertilizer solution, which consists of the entire complex of necessary minerals, and also begin to gradually encourage their adaptation to low air humidity and direct sunlight. After another three or four weeks have passed, the cuttings can be transplanted into open soil.

Reproduction by root suckers

As for the root suckers, the reproduction of remontant raspberries with their help becomes quite easy, although this variety of this berry, in comparison with the summer species, has quite a few of them.

In order to increase the planting material, it is necessary to cut out the center of the rhizome of each bush with a shovel in the spring and autumn. The growth in the center that remains will make the reproduction of remontant raspberries possible. This method is also suitable for any other type of raspberry. In addition, thanks to it, you can achieve the effect of "rejuvenation" of the whole raspberry plantation.

This is especially appropriate, since raspberries allow themselves to be grown in one place for up to fifteen years. However, this is exactly how much time it should be grown, since at the end of this period the bushes reduce their yield, which indicates the need to change the planting site. This creates a number of some difficulties in the process of solving this issue, but thanks to the "rejuvenation" of all possible difficulties can be easily avoided.

It should be remembered that it is in the fall that the remontant raspberry variety gives the most suitable offspring for "rejuvenation", although summer ones are also suitable. For a successful planting, the shoots must have a well-developed root system and strong stems. Immediately upon planting, you need to ensure that the root is in a straightened form. The top should be cut off, and the stem itself should reach a height of up to 40 centimeters.

During the summer, the remontant variety should be well cared for. The best shoots during this period will grow with the main part of the bushes. This can be the result of their excessive density, which will have a rather negative effect on the entire crop, so seedlings should be planted only with the onset of summer. This reproduction of raspberries has its drawbacks, although it is simpler than the first option.
