Raspberry Glen Ample is a European guest who is currently successfully winning her place in Russian gardens. This promising new variety quickly became widespread in Western Europe and occupies a leading position in terms of total planting area in industrial plantings and in garden plots. Such wide popularity of Glen Ample raspberry is promoted by its high productivity and endurance, combined with high taste.
Raspberry Glen Ample was created in 1998 at the Scottish Crop Institute in Dundee by crossing the British variety Glen Prosen and the South American Meeker raspberry. The selection result was successful: the absence of thorns and endurance was transmitted from the first parent to the Glen Ample variety, and from the second - high growth strength and productivity.
The raspberry variety Glen Ampl was not included in the register of breeding achievements of the Russian Federation, however, it was widespread in all regions due to its excellent characteristics. It is grown both on farms and in summer cottages.
The ripening period of the Glen Ample variety is medium late, the first berries in central Russia can be tasted in the second or third decade of July. The fruits ripen gradually, the yield of the crop lasts for a month. The ripening period can vary depending on climatic and weather conditions. The main crop is formed on two-year-old shoots. Glen Ample is a common raspberry (not remontant), but sometimes in very warm climates with a long summer season in August, flowers and ovaries can form on the tops of annual shoots.
One of the features of Glen Ample are vigorous, tough, rather thick stems up to 3–3.5 meters high, which give the plant a resemblance to a small tree. The bark on mature shoots is grayish-brown in color with a slight waxy coating. The length of the laterals reaches 0.5 m. Spines are completely absent on the shoots and laterals.
Laterals are fruit twigs with leaves and inflorescences that form on biennial shoots.
Thanks to its thick stems, Glen Ample raspberries look like a small tree
The yield of Glen Ample raspberries is high and stable. Two-year-old shoots bear fruit, from 20 to 30 fruit branches are formed on them, each of which is tied up to 20 berries. From one fruitful shoot, you can get a crop of 1.2 to 1.6 kg. When grown on an industrial scale, the yield is 2.0-2.2 kg / m2, but in garden plots, with increased attention to each bush, gardeners received a yield of up to 4-6 kg per square meter. Such a high yield characterizes Glen Ample raspberries as an intensive type with a high potential for fruitfulness, and this is its main advantage.
The yield of the raspberry variety Glen Ample is high - up to 1.6 kg from one fruitful shoot
The berries have a rounded-conical shape, when ripe they acquire a dull red color. On average, the weight of the fruit is 4–5 g, but with good care it can reach 10 g. Ripe berries are easily removed during harvesting. The presentation of the products is very attractive. Thanks to the delicate sweet and sour taste of juicy berries, the tasters rated the Glen Ample variety at 9 points. The direction of use of the fruits is universal, the berries can also be frozen.
Raspberry berries Glen Ample are round-conical in shape, their weight is 4-5 g (can reach 10 g)
When ripe, the berries can be on the bushes for 2-3 days without losing their marketable qualities, so they cannot be harvested every day. The dense structure of the berries and tightly linked drupes help preserve the fruits during collection and transportation.
Berries of the Glen Ampl variety are distinguished by their high transportability.
Raspberry Glen Ample is resistant to adverse factors. Winter hardiness and drought resistance are rated at 9 points; in frosts below -30 ° C, shoots require shelter. Disease immunity - 8 points, pest resistance - 7-8 points. Plants are not damaged by aphids, but may be susceptible to viruses.
Raspberry Glen Ample has good economic characteristics that allow you to get a decent harvest in any climate. However, if we take into account the peculiarities of the agricultural technology of this variety, it will be possible to increase its productivity.
The place for growing Glen Ample, like any other raspberry, is better to choose an open and sunny one, but if this is not possible, then the variety can tolerate a little shading. The soil structure should not be too light or too heavy. The variety is quite hardy to dry air and soil, but still grows better, bears fruit and tolerates winter on moderately moist soils. It does not grow in swampy places, as it does not tolerate dampness of the root system.
Glen Ample, unlike many other European varieties, tolerates Russian frosty winters quite successfully. Best of all, the bushes of this variety winter in regions where there is snow cover throughout the winter, in this case, the plants do not need additional shelter. In southern latitudes, where there is not enough snow and there are often winter thaws, there are critical reviews about this variety. Plants did not always successfully tolerate such winter conditions. It can be concluded that the most comfortable raspberry Glen Ample will feel in middle latitudes, where the summers are quite warm and the winters are snowy.

Raspberry Glen Ample is demanding on the content of nutrients in the soil, with a lack of potassium and phosphorus, productivity decreases, as well as the size and quality of berries. It is important to add a sufficient amount of organic matter when preparing the soil before planting. Digging for 1 m2 add 2-3 buckets of humus or compost. 1 liter of wood ash and complex mineral fertilizers are added to the planting pits.
Since the bushes of this variety are very vigorous, a thickened planting will contribute to shading and create conditions for the development of fungal diseases. In industrial cultivation, the distance between rows should be 3–3.5 m, and between seedlings in a row - 0.5–0.7 m. In the conditions of a garden plot, the row spacing can be reduced to 2.5 m or a single-line planting. The rest of the planting requirements for this variety of raspberries are standard for this crop.
Row spacings for strong Glen Apple raspberries should be wide, 3–3.5 meters
This variety is prone to intensive formation of shoots and needs to be rationed. Experienced raspberry breeders in the fall recommend leaving up to 20 shoots per running meter. In the spring, the bushes are once again inspected and 10–12 replacement pagons per running meter are left. When placed in a row of plants at a distance of 0.5 meters, it turns out that 5-6 shoots remain per bush. The tops are shortened by no more than 20–25 cm, since fruit-bearing branches are formed along the entire length of the shoot. Long pruning increases yield and yield.
Two-year-old shoots, when the crop is ripe, cannot withstand its severity and require a garter. The height of the trellis should be 1.8–2 m. When tying vigorous varieties of raspberries, the so-called spiral method has proven itself well. Only the first shoot is tied to the trellis. The next row is taken outside, wrapped around the wire in a spiral and bent under the first. In this way, all subsequent shoots are recorded. The advantage of this method is that you do not need to tie each shoot, all branches and laterals have enough space, and good access for harvesting is formed. Fruit branches, despite their considerable length, are quite strong and do not require a garter.
Despite the fact that the Glen Ample variety is positioned as relatively resistant to dry air and soil, the yield will be higher and the quality of the berries is better if the plants are adequately watered. Especially raspberries need moisture during the period of setting and pouring berries. For maximum moisture retention in the soil, mulching with organic substances is used, as for any other raspberry.
Intensive varieties, such as Glen Ample, reveal their full fruiting potential only when the soil is supplied with sufficient nutrients. Raspberries are especially sensitive to a lack of nitrogen, as they carry it out of the soil in large quantities.
The most effective feeding is with liquid organic fertilizers, such as: fermented infusion of bird droppings (diluted with water in a ratio of 1:20) or cow dung (diluted 1:10). For each square meter, 3-5 liters of such fertilizer are applied. In the absence of organic fertilizers, a urea solution (30 g per 10 l of water) is applied, 1–1.5 liters per bush. The first feeding is carried out in the spring, and then it is fed another 1-2 times with an interval of 2-3 weeks.
With a rather high immunity of raspberry Glen Ample to diseases (8 points), in order to avoid infection, as a rule, it is enough to comply with the growing conditions and the rules of agricultural technology, as well as to carry out preventive measures. Due to the wax coating on the stems, the plants are relatively resistant to fungal diseases such as didimella and anthracnose. There is some vulnerability of the variety to viral diseases, as well as with high humidity and thickened plantings, Glen Ample raspberries can suffer from powdery mildew and rust.
With a disease of raspberries with powdery mildew on berries, points of growth of young shoots and leaves, areas with a light gray bloom of a cobweb character are formed (they look like they are sprinkled with flour). Fruits lose their presentation and quality, become unfit for consumption. To combat powdery mildew, biofungicides (Fitosporin-M, Planriz, Gamair and others) are used, which are environmentally friendly. These preparations contain live bacterial cultures that suppress the growth of pathogenic fungi. More effective (but less harmless) chemicals such as Topaz, Bayleton, Quadris and others.
In case of raspberry disease with powdery mildew, the leaves are covered with a light gray bloom.
Signs of raspberry rust are small convex yellow-orange pads on the upper side of the leaves, as well as gray sores with a reddish border on annual shoots, which merge into longitudinal cracks. Severe rust damage leads to drying of the leaves, which affects the yield and reduces the winter hardiness of plants. The most effective way to combat this disease is the use of chemical fungicides such as Poliram DF, Cuproxat, Bordeaux liquid and others.
Raspberry rust is characterized by the appearance of convex yellow-orange pads on the upper side of the leaves.
For the prevention of raspberry diseases, it is recommended to apply the following measures:
Raspberry Glen Ample is resistant to aphid attack, which is a carrier of many diseases. In order to prevent the attack of other pests, a number of preventive measures are used:
Raspberry Glen Ample is an excellent grade. It is difficult to find any disadvantages in it - they are absolutely insignificant in comparison with the advantages. The beautiful and large berries of Glen Ample will decorate the gardens of any region, given the peculiarities of the variety and give this raspberry a little attention. Delicious and healthy fresh fruits can be consumed in the summer season, as well as taken out of the freezer in winter and remember the summer.
I have several professions of different profiles, including a musician and an accountant. Higher education.

The Glen line is the most popular in Western Europe. What are the varieties Glen Ample and Glen Fine. The first occupies the bulk of European plantings, the second was recognized as the most productive for 2 years in a row. We have already talked about these varieties, they are common in Russia, have numerous reviews of gardeners, are grown not only in the central part of the country, but also in the Urals and Siberia. The hero of the current article is the Glen Dee variety, a new and promising variety, bred only recently, which is actively gaining popularity and is only undergoing trials in the CIS countries.
Glen Ample was bred in Scotland. To create a hybrid raspberry variety, scientists from the James Hutton Institute of Plant Industry from Dundee took two mother varieties - Meeker and Glen Prosen. The British variety Glen Prosen imparted hardiness and thornlessness to the Glen Ample raspberry tree, while the South American Meeker imparted high yields and vigorous growth. There is no Glen Ample raspberry in the register of the Russian Federation, but this does not prevent the standard hybrid from gaining popularity among farmers or summer residents.
Of great importance for every gardener is not only the description of the variety and gardeners' reviews, but also its pros and cons, which you need to know in advance. Glen Coe raspberries are characterized by the following advantages:
The only drawback of Glen Coe raspberries is their insufficiently high frost resistance. In regions where winter frosts drop below –20˚C –25˚C, bushes should be bent down and covered. At the moment, no other shortcomings have been identified in the variety.
