Standard raspberries differ from garden raspberries in the thickness and woody structure of the stems. The strongest shoot is selected, a standard is formed, and the rest are removed. If you do not prune, you will end up with an ordinary thickened bush.
What does standard raspberry mean?
The natural form of the crop is bush, the height and volume depend on the variety (whether it is a hybrid or a variety) and the place of growth. Over the course of a season, raspberries form quite a lot of root shoots, which have to be removed. Agricultural technology consists of pruning and fixing the stems to a support, especially if it is a tall bush.
Most of the shortcomings were eliminated through selection in 1986, when Professor Kichina V.V. created a culture with 1-3 stable, tough and rather thick stems for raspberries. This variety requires molding only at the beginning of growth. The lower part of the trunk (trunk) is bare, then there are skeletal branches in several orders.
This form does not require shelter for the winter and simplifies berry picking.According to reviews from gardeners who grow raspberries on a trunk, they are more productive than ordinary bush raspberries and are less affected by fungus, because air circulates better in the inner part of the crown. But the root system of all species is the same, so it is not possible to completely get rid of the growth; it should be removed.
Raspberries on a trunk (pictured) are clearly different from bush representatives.
Advantages and disadvantages
Standard varieties have their own advantages, for which gardeners value them.
Pros:
- stable yield;
- repairability;
- large fruit;
- frost resistance, most of the standard raspberry varieties can be grown in the Moscow region, in the Urals, in the Middle Zone;
- elastic and strong stems that easily support the weight of the fruit;
- the growing season does not slow down in partial shade, the berries do not bake in the sun;
- does not require crown cover for the winter;
- has strong immunity to infections.
Minuses:
- For full growth, more space is needed than for the bush variety.
The best varieties of standard raspberries
For cold regions, frost resistance is a priority, for southern regions - the ability to withstand high temperatures and a dry climate. There are old time-tested standard varieties and relatively recently created, new raspberry hybrids.
Tarusa
The Tarusa variety is one of the first non-remontant varieties. Created in 1992. Experimental cultivation showed good frost resistance (-250 C), but responds poorly to high air and soil humidity. Standard raspberries are recommended for growing in areas with a dry climate.
General characteristics:
- The height and volume of the crown is within 1.5 m.
- The lower part of the central stem is without shoots; they begin to form at 1/3 of the length, branched, without thorns.
- The foliage is intense.
- The raspberries are large-fruited, the berries are bright red, weighing 15 g, cone-shaped with a blunt end, length - 5 cm.
- The taste is sweet and sour, the drupes are large, the planting is dense, the flesh is juicy with a pronounced aroma.
4-5 kg of berries are harvested from one raspberry bush.
Galaxy
Galaxy is a relatively new variety of semi-remontant standard raspberries. Active fruiting begins in mid-July and lasts three weeks. The second wave is characterized by the appearance of single berries on 20% of young shoots. Starts in the second half of August.
The crop is suitable for cultivation in all climate zones where winter temperatures do not fall below -28 0C. The galaxy tolerates drought and high humidity well.
Characteristic:
- The standard part of the raspberry is short. The variety forms powerful stems with very long laterals with a dense arrangement of berries.
- Plant height is up to 2 m. Stem formation and formation of root shoots are intense. Thorns in the form of rudiments are observed only at the base of perennial shoots.
- Fruits weighing up to 18 g, dark red, with a matte sheen. The shape is slightly elongated, the seeds are small.
- The skin is thin, the raspberries are not transportable. It cannot be stored fresh.
- The taste is sweet, the structure is soft and juicy.
Penguin
Standard raspberry Penguin of remontant type. Bred in 2006 for cultivation in the central zone and the Moscow region. Frost resistance – 250 C. Responds normally to drought and overwatering. Does not get sick, pests practically do not affect the crop. Penguin is one of the high-yielding standard varieties. You can collect up to 6 kg from a bush.
Characteristic:
- Medium-sized raspberries - up to 1.2 m.
- The stems are powerful, with short internodes.
- Shoot formation is weak.
- There are practically no root shoots.
- The berries are round, dark crimson. Weight – 10-13 g, length – 3-4 cm. The skin is elastic, the raspberries are transportable and can be frozen.
- Fruiting is extended.
The fruiting cycle lasts four weeks. The second wave lasts from August to October.
Fairy tale
Raspberry Skazka is based on Tarus. The variety is not remontant, but has long-term fruiting. It does not have an active phase; it forms berries from July to September. Frost resistance up to -22 0C, if the indicator is lower, the raspberry needs insulation, which is problematic due to the height and tree-like structure of the stems. Does not tolerate high soil and air humidity. Recommended for the North Caucasus regions.
Varietal characteristics:
- Raspberries form a standard bush. It has not one, but several central thick tree-like stems up to 2.5 m long.
- The form is spreading, 4-5 skeletal branches with intensive shoot formation are formed on each trunk.
- The berries are bright red, the peel is elastic, the raspberries are transportable, do not fall off, and the peel is dry.
- Fruit weight is 12-15 g, the pulp is juicy, the taste is sweet and sour, the aroma is weakly expressed.
- Due to branching, up to 10 kg of crop is harvested from one bush.
Sturdy
The classic standard variety Krepish with one powerful trunk, not counting replacement shoots. Branching begins from 1/3 of the part, more intense towards the crown. A variety of remontant type, fruiting from June to September. Characterized by good frost resistance down to -300 C, raspberries calmly respond to drought and prolonged rains. The standard variety is grown from Siberia to the South; different climatic zones do not affect the taste of the berries and the fruiting rate.
What does a raspberry look like:
- The plant is branched and reaches a height of 1.8 m.
- The berries are dark red, semi-oval in shape.
- The structure is juicy, but not watery, elastic, sweet, the seeds are small.
- Fruits up to 18 g. They are densely located on peduncles.
- Productivity – 4-5 kg.
Planting standard raspberries
Standard raspberries are planted in the fall only in the southern regions. Experts recommend selecting a seedling for the site in the spring (April).
The place for raspberries should be sunny or with periodic shading. When planting linearly, leave a distance between standard varieties of at least 1.2 m. A wetland area is not suitable for the crop.
Sequence of work:
- Two weeks in advance, dig up the soil, add organic matter, peat and sand.
- On the day of planting, dig a 50x50 cm hole, mix the turf layer with humus, add superphosphate and wood ash.
- Part of the substrate is poured to the bottom, the raspberries are placed in the center, and the hole is filled to the brim.
- Compact and water with a solution that stimulates root growth.The neck is deepened by about 5 cm.
Caring for standard raspberries
The agricultural technology of the varieties is standard, as with all crop varieties. Cultivation differs only in the method of pruning the standard plant.
Watering
Watering is oriented towards the frequency of rains, especially if the standard variety is drought-resistant. During the summer period, the plant is moistened up to five times with a volume of 30-40 liters so that the soil at a depth of 30 cm does not remain dry. This is a regime for adult raspberries; for seedlings in the first season, soil moisture is maintained constantly, but stagnation is not allowed. At the end of September, moisture-recharging irrigation is carried out using 25 liters of water.
Top dressing
Standard varieties are demanding of fertilizers, especially organic matter. In the first year of growth, raspberries are given one root dressing. Mix mullein or bird droppings (0.5 kg) with complex mineral fertilizer (5 tbsp), add nitrophoska (2 tbsp), dilute in water (10 l). One plant will require 2 liters.
In subsequent years:
- In early June, potassium sulfate, nitrophoska, and liquid organic matter are given.
- In early July, potassium sulfate is added under the standard raspberries.
- After picking the berries, they are fertilized with superphosphate.
When flowering ends and the berries begin to fill, spray with Energen.
Pruning standard raspberries
When forming a standard crop, it is important to prune correctly.
Algorithm:
- After planting, the central strong stem is selected, the remaining shoots are cut off.
- When the trunk reaches 1-1.2 m, pinch off the top.
- All vegetative buds are removed from the standard part. Only those where a crown of side shoots will form are left.
- In this form, raspberries overwinter.
- Next spring a crown will form.If the variety is early ripening, the plant will bloom.
In autumn, it is advisable to trim the side stems of standard raspberries, leaving the required number of replacement buds, or remove the old stem part completely to ground level. In the spring, the pruning pattern is repeated.
Mulching
In the first year of growth of standard raspberries, cover the root circle with compost. Watering or rain washes away some of the mulch and the layer becomes thin. Its optimal thickness is 6 cm, so manure humus is added several times. Raspberries of reproductive age are mulched immediately after spring pruning. On damp soils, the surface is left open and regularly loosened, improving aeration. Remove weeds.
Preparing for winter
For standard raspberries, if their frost resistance corresponds to the growing climate, the crown is not insulated. Fruit-bearing shoots are simply cut off. Water-recharging irrigation is carried out, they are hilled up, covered with a layer of peat or sawdust, straw is placed on top, and a snowdrift is thrown in in winter. If a standard variety is grown in the form of a tree, if necessary, you can wrap the stem and skeletal part with covering material.
Protection from pests and diseases
At the end of the season, all remnants of weeds are removed and the soil is dug up to kill overwintering pests and fungal spores. 10 days before frost, raspberries are treated with colloidal sulfur and the soil with Karbofos. In the spring (before the buds open), water the root circle generously with Topaz solution and cover it with ash. After seven days, the raspberries will form young leaves; they are sprayed with any antifungal drug.
Propagation of standard raspberries
It will not be possible to make layering, because...The lower branches are high and it is difficult to bend them down and cover them with soil. For the standard variety, you can use the cutting method. When the raspberries fully bear fruit, they are cut off and the material is prepared. Place in a container with fertile substrate and lower it into the basement for the winter.
In spring, cuttings are taken out to the site. The swollen buds will show what material has taken root. At the end of August, raspberries must be planted in a permanent place. Cuttings are an effective but labor-intensive method. Standard varieties are often propagated by root shoots. There is not much of it, but quite enough for planting.
Conclusion
Standard raspberries compare favorably with bush raspberries in terms of productivity, frost resistance and undemandingness to watering. All varieties are large-fruited, new varieties of remontant type. Raspberries with strong shoots do not require fixing support. Special pruning allows the plant to grow in the form of a tree.
