7 main conditions for a record harvest of remontant raspberries
The choice of remontant raspberry varieties for planting does not guarantee a rich harvest. Plants need quality care, and it is different from caring for regular summer raspberries.
The bountiful double harvest that remontant raspberries are famous for requires a lot of nutrients. The culture reacts especially strongly to a lack of nitrogen: the bushes become weak, the leaves lose color. In the first half of summer, nitrogen-containing fertilizers must be applied to the soil of the raspberry tree 2-3 times. Best of all, raspberries respond to liquid fertilizing with organic matter, for example, chicken droppings. It is poured with water and infused for 10 days, and then diluted in a ratio of 1:20 and added under each bush. The cowshed also works well. It is fermented for a week and diluted with water in a ratio of 1:10. It is recommended to use about three liters of organic matter for one square meter of raspberry plantings.
In spring and during flowering, phosphorus-potassium fertilizers are applied under raspberry bushes.
The root system of remontant raspberries is located in the top layer of the soil, so regular watering has a big effect on the yield. Their frequency depends on the weather conditions: in dry and hot weather, water often and abundantly, in wet weather, watering is reduced or stopped completely. under the bushes, it should be saturated with moisture to a depth of 40 cm. The raspberry plant experiences the maximum need for water during the period of flowering, growth and ripening of berries. In dry autumn, it is also advisable to conduct subwinter watering.
Raspberry bushes must be mulched. This protects the root system of plants from freezing in winter and from drying out in summer. In addition, a layer of mulch inhibits the growth of weeds and retains moisture in the soil. Sawdust, humus, straw, compost are used for these purposes, laying them around the seedlings immediately after planting. An important condition for mulching: the layer of covering materials after shrinkage should be at least 5 centimeters. In spring, when the soil is loosened, the mulch is embedded in the soil, and then a new layer is laid under the bushes.
Periodic loosening of the soil
An obligatory part of maintenance is regular loosening of the soil. This improves oxygen access to the roots, promotes the development of beneficial microflora in the soil, maintains an optimal level of moisture. The first loosening is performed in early spring before bud break. The following - as needed. The appearance of dry crust on the surface of the earth and the growth of weeds can serve as a guide.
In order not to harm the roots, the maximum loosening depth under the bushes should not exceed 8 centimeters, in the aisles - 12 centimeters. It is recommended to perform up to 6 procedures per season.
Correct pruning of shoots
The procedure for pruning raspberries depends on the number of crops that are planned to be obtained during the season. If the harvest is planned alone, in late autumn or early spring (before bud break), cut out all the branches of the raspberry. Shoots are cut off completely, without leaving stumps. If two harvests are planned for harvest, in the fall or early spring, old shoots and root shoots are cut out, leaving annual branches, from which the tops are cut off by 25 centimeters. Raspberry bushes planted this year are left in the first autumn winter with stems about 20 cm high. The general rule: for the bush to develop well and bear fruit, no more than eight yielding shoots are left on it. All weak growth is removed during the season.
Protection from pests and diseases
Repaired raspberries are more resistant to diseases and pests than common summer ones. However, additional protection will not harm it.To prevent fungal diseases in spring and autumn, after harvesting, the raspberry tree is sprayed with 1% Bordeaux liquid. During flowering and the formation of ovaries, regular examinations of the branches are carried out and all diseased and infected shoots are removed.
Tying thin shoots
A large amount of berries on top of raspberry shoots can damage them. To prevent this from happening, the branches are tied up. When bush planting - to the pegs, when trenching - to trellises. Shoots of remontant raspberries, from which two crops are harvested per season, are separated with a garter: one-year-old shoots are tied separately, two-year-old shoots are separately tied.

Repairing raspberries: planting and care, feeding and pruning
Caring for remontant raspberries has its own characteristics and differences from the care of conventional raspberry varieties. With remontant raspberries, you can harvest twice a season, but the quality of the berries of the second harvest is less high than the first.
Let's consider in detail: spring care for remontant raspberries, proper planting, pruning, watering, feeding.
Repaired raspberries have advantages over conventional varieties - they are more resistant to diseases and pests, and have almost no wormy berries. All remontant varieties are large-fruited, easy to care for.
Why it is necessary to observe the neighborhood of plants
Each plant requires certain care, appropriate soil conditions, watering, has the characteristics of the root system and needs fertilization. If the correct neighborhood is not observed, then the culture may suffer due to excess or lack of moisture and nutrients, as well as from the roots of those green spaces that are planted nearby. Experts divide plant compatibility into three categories: positive, neutral and depressing.
Getting a good harvest from raspberry bushes largely depends on what you plant next to the berry. Subject to the recommendations of agronomists, you can achieve not only a large number of berries, but also other positive results, such as the absence of overgrowth and the need for painstaking care. Therefore, if the area of your land plot is small, then you can save space by planting other crops in the immediate vicinity of the raspberry tree. But for this you need to familiarize yourself with the compatibility rules.

Planting raspberries in the greenhouse
The size of the greenhouse for raspberries depends on the planned planting volumes.
To ensure uninterrupted fruiting, the first batch of seedlings is planted in January and after 1.5–2 months the fruits ripen.
Bushes from which the crop was harvested are pruned and left dormant. The second batch is planted in March. Thus, the continuous ripening of fruits is being established.
In order for the planted seedlings to take root and give a good harvest, they should be bought in special nurseries or well-recommended retail outlets.
Technology for planting raspberries in greenhouses:
- During the preparation of the soil, humus or peat is introduced into it.
Preparing the soil in the greenhouse for planting raspberries.
Planting seedlings in holes.
Mulching the surface of the earth with peat.
To improve the soil, fertilizers are applied, the composition of which depends on the type of original soil.
Caring for raspberries in a greenhouse is simple.
It is important to take into account some of the nuances and then the likelihood of a good harvest will increase:
- As you know, raspberries are very fond of fresh air and develops well even at low air temperatures. ... For her, it is considered the norm + 12-14 degrees at night and + 19-21 during the day. Therefore, in warm weather, the greenhouse needs to be ventilated frequently. Experienced gardeners recommend removing the end frames from the frame to provide access to the raspberries for beneficial insects.
- To keep the moisture level normal, raspberry bushes need to be watered twice a week. ... And in order to ensure that oxygen gets to the roots, you should loosen the ground around the bushes every 5-7 days.
- Many gardeners mulch the soil to make caring for raspberries less troublesome. ... Sawdust and crushed nutshells are used as mulch. And some just cover the soil with agrofibre.
- It is imperative to control the level of humidity ... It should be in the range of 65–75%.
- One of the important points of care is regular plant feeding. ... To do this, it is necessary to apply mineral fertilizers to the soil every two weeks together with irrigation. Gardeners recommend applying fertilizers based on manure, nitrogen and ammonium nitrate.
- Pollination of raspberry flowers is an integral part ... It is from him that the quality of the fruit will depend. To do this, you need to run bumblebees in the greenhouse. They are much faster than bees and also tolerate low air temperatures very well.
Compliance with the technology of growing raspberries in a greenhouse allows you to get a crop in two months after planting.
Before harvesting the fruits for a day, you must stop watering the raspberry tree. This will contribute to the production of aromatic and sweet berries. For raspberries to remain juicy immediately after harvest, the fruits must be placed in a cold room. In no case, you can not transfer raspberries from one container to another, as it can choke and thereby deteriorate the presentation. Therefore, it is necessary to immediately collect them in special boxes.
An important point! Raspberries should be picked every morning.
Growing raspberries indoors can bring not only pleasure for the gardener, but also not a bad profit.
Because in winter and spring it is almost impossible to buy a berry. And the places where it is are simply shocking at the cost of it. Therefore, growing raspberries in a greenhouse automatically becomes a brilliant idea for a personal business. It is only important to weigh the pros and cons and forward!
Raspberries are rarely affected by pests and diseases. But if this happens, try to avoid the use of chemicals, it is better to use alternative methods or biological preparations.

Pruning features: autumn or spring
As you can see, to the question: "How to properly cut remontant raspberries?" no, and there can be no single answer. It all strongly depends on the climatic conditions of the region where raspberries are grown. And even if you chose to grow remontant raspberries with one, but a good harvest in early autumn, then not everything is as simple as you would like.
Obviously, for regions with mild winters, there is little point in autumn pruning, because even after the plants have borne fruit, they will be able to develop for a long time under favorable conditions, accumulating nutrients for future use. Moreover, if you cut off raspberries in the fall, and frosts do not come in the next month and a half, then the underground buds on the rhizome may prematurely germinate. And with the onset of frost, they will freeze, and the next year's harvest will be significantly reduced. Spring pruning can prevent all of these problems.
Oddly enough, the transfer of pruning remontant raspberries in the spring is preferable for areas with severe and little snowy winters. At the same time, not removed raspberry shoots can contribute to better snow retention. Moreover, according to the observations of experienced gardeners, the farther north the region, the greater the productivity of raspberries is noted when pruning is carried out precisely in the early spring.
There is also an option to wait until the buds begin to bloom and only then carry out a complete pruning of the shoots. This makes sense, since at this moment the bushes will be able to replenish their supply of growth substances, which are formed only in the opening leaves. Therefore, after pruning raspberries at this particular time, the plant is able to quickly wake up and grow, which is especially important for the northern regions.
All work is carried out in absolutely the same way as in the autumn pruning, only in the spring.
Loosen the soil regularly and renew the mulch layer
To provide the roots of remontant raspberries with good oxygen access, to promote the development of beneficial microflora in the soil and better moisture retention, it is necessary to loosen the ground near the bushes regularly (4-6 times per season).
The first loosening is carried out in early spring before bud break on the shoots, and subsequent loosening as needed, when it becomes noticeable that a crust has formed on the soil surface or weeds have appeared. The last loosening of the soil is carried out in late autumn after significant cold snaps - this technique helps to destroy some of the pests wintering in the soil.
It is necessary to loosen the ground near the bushes shallowly, by 7-8 cm, so as not to touch the roots. In row spacings, loosening can be deeper, but not more than 15 cm.
If your berry has been mulched since spring, do not forget to regularly check the condition of the mulch and renew its layer as needed. It protects plantings from weeds and retains moisture in the soil, which is extremely important in summer, and also protects raspberry roots from overheating the soil.
As mulch for raspberries, you can use peat, humus, hay, straw, sawdust, crushed bark, compost (all with an initial layer of about 10 cm, taking into account that after settling the layer thickness is at least 5 cm) or synthetic black agrofibre with a density not less than 50 g / m2
Repaired raspberries in summer are not the most capricious shrub, unpretentious, resistant to diseases. However, he will also be grateful to the gardener for a timely set of measures for competent care - and he will certainly thank him with a bountiful harvest, or even more than one!
