Octavia raspberries: characteristics, features of agricultural technology
Raspberry Octavia is excellent for growing in temperate regions. The variety is chosen for cultivation for its frost resistance and disease resistance. Description of the plant, as well as the technology of its cultivation, read below.
The bush was selected in the UK at the East Molling test station. Octavia raspberries were bred in 1992 by crossing Glen Ampl and EM 5928/114.
Did you know? There is an opinion that raspberry is not a berry, but is a multi-species, that is, it consists of many small fruits grown together.
Description and characteristics of the variety
Shrub reaches up to 2 m in height. Stems are powerful, with good flexibility. Fruit shoots reach up to 20 cm in length. A distinctive feature of the plant is that the thorns are mostly located only in the lower part of the culture at a height of up to 40 cm, and those that are higher are soft and do not cause harm when picking berries. Leaf plates are large, light green.
The berries are quite large, reach up to 7 g of mass. The fruits on the branches are collected in large brushes, they are dark pink or red. The shape of the berry is a regular cone, along its entire perimeter there is a slight pubescence. The berry is characterized by good transportability due to the dense structure of the pulp. Raspberries have a sweet taste, without acid. The aroma is pronounced, sugary.
Advantages and disadvantages
- Among the positive qualities of the variety are:
- excellent transportability;
- resistance to gray rot and stalk diseases;
- berries are not prone to drying under the influence of the sun;
- good frost resistance.
A disadvantage of the bush is a high risk of root rot infection, as well as a change in the taste of the product with a lack of light.
Drought resistance, frost resistance
Frost resistance of the Octavia variety reaches up to -30 ° CTherefore, it can be cultivated in regions with a temperate climate, without resorting to the procedure of winter shelter. But when landing in areas with severe weather conditions, such as the northern and northeastern regions of Russia, additional care will be required during the cold season.
The plant does not belong to drought tolerant varieties. With excessive heat, the growth of the shrub slows down, and fruit formation is also inhibited.
Productivity and fruiting
Depending on the growing region, the fruiting period falls in mid-July or early August and lasts for 5-6 weeks. Mid-late Octavia raspberry variety brings up to 3.5 kg of berries from one shrub.
To grow a strong raspberry bush, you must adhere to planting technology. Read about how to choose the right place for cultivation, as well as prepare seedlings before planting.
Important! All planting work in the autumn period must be completed 3 weeks before frost.
Raspberry seedlings can be planted in open ground in spring or autumn. In the spring, planting material is planted in mid-April, when the air temperature becomes as comfortable as possible up to + 15 ° C, and the buds on the bush have not yet woken up. In the fall, landing is carried out in the middle or end of September.
Choosing the right place
The site should be free of drafts, so that the wind cannot break the fragile branches of the bush, and there will also be less risk of the spread of fungal infections in the wind. That is why it is better to plant raspberries along the fence or behind the house.
The terrain should also be in partial shade. It is advisable to choose a site where the sunshine until about noon, so the plant will not suffer from excessive heat, and the berries will not become acidic from a lack of light.Groundwater should lie 1.5 m deep, otherwise there is a risk of rotting of the root system.
Selection and preparation of planting material
Sapling should be purchased only in a specialized nursery, which guarantees the authenticity of the variety. When choosing planting material, be sure to inspect it for rot and diaper rash, and also pay attention to the root system.
It should be elastic, uniform in structure and color, its length should be at least 20 cm with many small processes. The presence of dry or rotten roots is unacceptable. You should not buy a seedling that has been packaged in a plastic bag for a long time.
The packaging should be made of natural fabric, and the rhizome itself should be contained in a specially prepared clay substrate. Immediately before planting, you should unpack the seedling and place the rhizome in a solution of Kornevin 15 g per 1 liter of water to stimulate the rapid development of the culture.
Soil on the site for planting raspberry seedlings must be prepared for six months. The site is dug up to a depth of 30-40 cm and the entire perimeter is cleaned of weeds and other debris.
For each m² of area you need to make fertilizers of 10 kg of humus, potassium sulfate 30 g and 50 g of superphosphate. If the soil is heavy, then 5 kg of river sand is applied to the m². Planting of bushes is carried out with an interval of 50 cm between plants and 1.5 m between rows.
Important! When planting a seedling in a hole, make sure that the root of the neck is at the level of the soil. If the plant is too deep, it will be difficult for it to shoot, and if the level of planting is too high, there will be problems with drying of the rhizome and freezing of the plant in the winter.
Technology planting raspberry bush in open ground:
- Dig a hole 40 cm deep and 50 cm wide.
- Deepen the plant in the pit and gently straighten the rhizome.
- Fill the hole with soil and compact it tightly.
- Pour a bucket of water into the bush.
- Mulch the soil near the stem with sawdust.
The plant requires regular maintenance. In the summer, the shrub is especially in need of moisture, so it is watered as the earthen coma dries up 1-2 times a week. 5-6 liters of water are consumed per plant.
After each watering or rain, the soil near the bushes is loosened to saturate the rhizome with oxygen. Once a month, you can mulch the soil with peat or sawdust to avoid the appearance of weed grass, as well as maintain moisture.
In the autumn, culture needs to be cut. 2-year-old shoots that have already been fruiting are removed, and dry, diseased stems are also cut. In spring, the shoots are shortened, the optimal height after the procedure is 1–1.5 m, pruning will enhance the growth and fruiting of the bush.
In order to avoid breaking off branches, as well as to facilitate care and harvesting, raspberries are tied to a trellis. Along the perimeter of each row of plants you need to drive in wooden supports at a distance of 2 m from each other. A wire is attached to them at a height of 1 m from the soil, on which shoots are tied.
Harvesting and storage
Harvest in dry weather. It is advisable to choose no morning time for picking berries, because dewdrops may remain on them, which will reduce the stamina of products. For long-term storage and transportation of the crop, it is necessary to collect fruits that have not reached full maturity.
Fully ripened berries are harvested in order to immediately eat or cook jam. Fruits are carefully picked and stacked in wicker baskets. Fruits can be stored at a temperature of + 25 ° C for 24 hours to preserve the berries for 3-5 days, they are placed in a refrigerator at a temperature of + 4 ° C.
Before wintering, it is necessary to clean the area on which raspberries grow. If in the summer the soil was mulched, then this layer is removed, because field mice that harm the plant are often wound up in it.The territory is cleaned of weed grass, the soil is dug up.
The bushes bend and weave together, so as to protect against strong gusts of wind. In winter, bent shoots quickly cover with a layer of snow, which will serve as protection against freezing. In regions with a harsh climate above the raspberry, you can build a film greenhouse.
Raspberries can be propagated in several ways:
Reproduction by seed method is very laborious, but thanks to it all the qualities of the variety are preserved. For planting, choose the best fruits that are squeezed and rubbed on a sheet of paper to separate the bones.
Seeds are dried and sown in containers filled with a mixture of sand and coconut fiber. The substrate must be constantly moistened and warm, therefore pots with crops are kept at a temperature of + 20 ° С. After the seeds hatch and the sprouts form 3 leaves, they can be planted in more spacious containers.
Did you know? The first raspberry plantations were discovered on the island of Crete in the III century BC. e.
It is not difficult to propagate shrubs using cuttings. To do this, in the autumn period it is necessary to prepare cuttings 15 cm long and 3 cm thick, which are placed in wet sand for a period of 3-4 months. With the onset of the spring thaw, cuttings are planted in specially made trenches 8 cm deep. Until the fall, full-grown seedlings with a developed root system will be formed from these plantings.
Diseases and Pests
Most often, the plant affects root rot. The disease provokes a fungus of the phytophthora genus, which for a long time can quietly seep into the plant tissue. Fungal infection occurs due to the fact that the plant grows on heavy soils that retain moisture.
Rhizome in a waterlogged environment quickly undergoes the spread of fungal spores, as a result of which it ceases to supply the stems with the necessary nutrients. The bush begins to fade, its leaf blades turn yellow and fall off. The shoots dry out for a while, and then the whole bush.
- The acquisition of high-quality planting material.
- Planting a bush on light soils.
- Use of 1% copper sulfate (100 g per 10 l).
Raspberry bushes most often attack spider mites and a bug-soldier. The bug soldier is a large insect that reaches up to 12 mm in length. The pest has a bright red color with black spots on the elytra. Insects winter in the bark and dry leaves, wake up in the spring, and the females lay their larvae. Pests feed on the juice of leaf blades, which leads to their withering and shedding.
- Cleaning the area from accumulated debris.
- Irrigation with the drug "Fufanon" (5 ml per 10 l of water).
A spider mite is a small insect reaching up to 0.4 mm in length. Pest females winter in the remains of weed grass or fallen leaves, and with the advent of spring they begin to produce offspring. Ticks feed on the juice of leaves and stems, which is why they fade and turn yellow.
- Harvesting damaged leaves and stems.
- Irrigation with a soap-ash solution (300 g of soap, 300 g of ash per 10 l of water).
- Spraying with the preparation “Karbofos” (5 ml per 10 l of water).
To avoid the spread of fungal infections and pests, it is necessary to carry out preventive measures:
- timely pruning of the plant;
- cleaning the site of vegetable debris;
- weed removal;
- irrigation with 1% copper solution (100 g per 10 l of water), which is carried out 2 times with an interval of 2 weeks in the spring.
Despite the fact that Octavia raspberry is not a high-yielding species. It is large-fruited and has good winter hardiness, which favorably distinguishes it from other varieties.
