Raspberry Glen Ample (synonyms Glen Ample, Glen Ample) is a versatile variety, whose berries are suitable for fresh consumption and canning, and also perfectly tolerate freezing, retaining their shape and taste after defrosting. The variety belongs to the standard, among gardeners there is a definition - a raspberry tree.
Breeding history of the variety
The authorship in the breeding of the hybrid belongs to the Scottish Institute of Plant Industry named after James Hutton in the city of Dundee (Szkocki Instytucie Produkcji Roslinnej w Dundee). Glen Ample became known in 1996. Outwardly, the shrub, indeed, resembles a tree-like plant, hung with bright, as if illuminated from within, lantern berries at the time of harvest. The breeders used the method of distant crossing in their work, which allowed them in the end to combine the best properties of the Glen Prosen and Meeker raspberries. The new hybrid gained height, power, high vitality even in a harsh climate, good health, excellent yield, taste, transportability.
Description of the variety
The vigorous upright self-fertile hybrid Glen Ampl belongs to non-repairable varieties - the plant bears fruit on the shoots of the second year. A distinctive feature is the structure of the bush. One shoot comes from the root, which gives life to 20-30 hard lateral branches. Subject to agricultural technology and in favorable conditions, the plant is able to reach 3 meters in height. Raspberries need a garter on the trellises, because together with the harvest, which is more than 20 large berries on each branch, a high load on the stem is created.
Glen Ample has a powerful root system, a central shoot (stem), green at the beginning, gets a lignified structure in the second year of life, is painted in a reddish-brown tint, may have a whitish bloom on the bark. Large, slightly wrinkled leaves of a dark green color are located alternately, the shoots do not have thorns, with the exception of the lower part of the plant. During flowering, the raspberry is covered with large white flowers, which contributes to its decorative effect.
Ripening terms
The hybrid belongs to the mid-late varieties - the fruiting period falls in the second or third decade of July. In the more southern regions of our country, harvesting begins in mid-June.
Growing regions
Glen Ample is adapted for growing in a European climate, grows well in Ukraine, Belarus and in the middle latitudes, characterized by warm summers and snowy winters.
Yield
The hybrid variety has high yields - up to 4-6 kg per bush and 20 tons per hectare. Yields are stable, fruits ripen along the entire length of the shoot.
Berries and their taste
The organoleptic properties of Glen Ample are evaluated by 9 points on a 10-point system. Medium-sized round-conical berries weigh 4-5 grams. The firm juicy pulp has a delicate sweet taste with a light pleasant sourness and a bright red, even carmine color, with a rich raspberry aroma. For transportation, the berries are harvested at the time of the onset of technical maturity, but even during physiological ripeness, the fruits do not fall off the vine for a long time and retain their presentation.
Growing features
Glen Ample agrotechnical requirements are no different from traditional varieties of raspberries. The hybrid prefers well-lit places, but with light shading in the afternoon, otherwise the berry may begin to wither and dry. In summer cottages, a distance between rows of up to 2.5 m is observed, or a one-line landing is made. The traditional opinion of most gardeners: it is better to plant raspberries in the fall, but they take root well after the spring planting. During the summer season, the seedling manages to grow an excellent root system, and in winter it leaves a strong and healthy plant.
Site selection and soil preparation
The variety grows well on all types of soil, but its yield directly depends on the fertility of the soil. The soil must have all the necessary trace elements and organic matter. Preference is given to loams with a light loose structure with the addition of peat and sand. When preparing pits, the organization of a drainage layer is needed, since the hybrid does not tolerate prolonged waterlogging. Low-lying, swampy, as well as areas with a close occurrence of groundwater are contraindicated. Before planting, the soil is filled with organic matter and complex mineral fertilizers, providing a young plant with adequate nutrition for a couple of years.
Pruning
The height of the bushes has led to the fact that it has become the norm for gardeners, especially those who grow the variety on an industrial scale, to use the braiding method. In this case, the vine of the second year is not cut, its tops are braided around the wire of the trellis at about a meter height, making it comfortable to harvest the future harvest.
The second method is double pruning, which allows you to form a "raspberry tree". The replacement shoots are cut at the beginning of the growing season, shortening them to 1 meter. In the middle of summer, a second pruning-pinching of the lateral shoots that have grown during this time is carried out. This is how a bush resembling a tree is obtained.
Watering and feeding
Top dressing begins in the spring of the third year, by which time the young plantings have already "eaten" the nutrients introduced during planting. In the spring, organic matter and nitrogen fertilizers are introduced, provoking a rapid growth of the vegetative mass. In summer, plants need complex fertilizers, which include potassium and trace elements, in autumn it is time to introduce phosphorus-potassium compounds.As for watering, during the dry period, raspberries need additional moisture in the spring, during the period of flowering and budding. Recommended irrigation rates are from 30 to 40 liters of water under the bush.
Frost resistance and preparation for winter
High frost resistance allows the bushes to tolerate winters well. However, in the middle lane, the plant needs additional protection in order to endure frosts down to minus 30-35 degrees without loss. The shoots are untied from the trellises, bent to the ground and covered with non-woven agrofibre, sprinkled with mulch, spruce branches.
Diseases and pests
Glen Ample has a high resistance to diseases - 8 points on a 10-point scale. It is important to respect the possibility of airing the aisles. Thickening can provoke the appearance of powdery mildew. Fungicides are used as prevention of fungal diseases, insecticides are used against pests.
Unfortunately, raspberries, like other plants, do not bypass various diseases and pests. Only by armed with the knowledge and the necessary means for this, you can cope with such troubles. To help the plant, it is very important to be able to recognize the disease in time and begin timely treatment.
Reproduction
There are no problems with the reproduction of a hybrid - it gives a sufficient number of offspring. By separating them from the mother bush, the gardener will receive a lot of planting material.
Review overview
Most gardeners, like farmers, note the high decorativeness of Glen Ample and its taste. Raspberry lovers appreciate it for its excellent keeping quality of the berry - elastic pulp allows transporting the crop for sale over long distances. Nowadays, many people prefer freezing to heat treatment, and the hybrid is ideal for this purpose. Its berries retain their shape after defrosting and can serve as a decoration for desserts, a festive table in winter.
